BAMS Operation Concept
(click to view full)
The world’s P-3 Orion fleets have served for a long time, and many are reaching the end of their lifespans. In the USA, and possibly beyond, the new P-8 Poseidon Multi-mission Maritime Aircraft will take up the P-3′s role. While the P-8′s base 737-based airframe offers strong service & maintenance arguments in its favor, the airframe is expensive enough that the P-3s cannot be replaced on a 1:1 basis.
In order to extend the P-8 fleet’s reach, and provide additional capabilities, the Poseidon was expected to work with at least one companion UAV platform. This DID FOCUS Article explains the winning BAMS (Broad Area Maritime Surveillance) concept, the program’s key requirements, and its international angle. We’ll also cover ongoing contracts and key events related to the program, which chose Northrop Grumman’s navalized MQ-4C Triton Global Hawk variant.
Next-Gen Maritime Patrol Systems: Issues and Options
USN ERJ-145 ACS concept
The P-3 fleet’s heavy use in both maritime surveillance and overland roles points up a potential problem with its successor the P-8A Poseidon. The 737-based aircraft will be bought in fewer numbers than the aircraft it replaces, but its high end Littoral Surveillance Radar System (LSRS) capabilities could quickly turn it into a sort of “mini-JSTARS,” making it a platform with strong maritime and land surveillance capabilities like NATO’s similar sized Airbus 321-based AGS battlefield surveillance aircraft.
As an expensive but in-demand asset, the P-8′s coverage scope could easily translate into a fleet run ragged by high flight hours per airframe, and forced into early retirement. See the Strategic Review article “Brittle Swords: Low-Density, High-Demand Assets” [PDF] for more background on this phenomenon.
The logical response is to pair the P-8s with a lower cost counterpart.
Hence the P-8 Poseidon’s companion Broad Area Maritime Surveillance (BAMS) UAV program, run by NAVAIR’s PMA-263 program management office.
BAMS: Requirements and Missions

The BAMS UAV is formally designated MQ-4C Triton: “M” as a multi-mission aircraft, even though all of its missions are ISR/reconnaissance missions.
The name fits. In mythology, Triton was Poseidon’s son, and the messenger of the sea. Tritons will work with the P-8 Poseidon maritime surveillance aircraft on missions that will include maritime surveillance, collection of enemy order of battle information, battle damage assessment, port surveillance, communication relay; plus support for maritime interdiction, surface warfare, battlespace management, and targeting for maritime and strike missions. MQ-4C Increment 3 UAVs and beyond are slated to add SIGINT capabilities, to capture enemy communication and radar transmissions. They would begin replacing the current EP-3 fleet in that role.
The MQ-4C UAV’s required capabilities definitely placed it at the high end of today’s UAV spectrum. BAMS had to be capable of a completely pre-programmed mission track, communication plan, and sensor employment plan, with manual override possible to support real-time control and/or re-tasking. The baseline requirement for operation with the P-8A is currently Level II control (receipt of sensor data to/from), with a proposal to quickly increase to Level IV (full control except landings) in the P-8A’s first improvement cycle. It also needed the ability to land on its own if necessary, however, using pre-surveyed and pre-programmed air fields.
Many of those capabilities are already present in existing medium UAVs. The requirements that follow are not.
BAMS: expected ‘orbits’
(click to view full)
BAMS had to have a minimum mission radius of 3,000 nautical miles, with a 10 hour time to on-station at 2,000 nmi mission radius, and autonomous flight through moderate icing or turbulence. More to the point, the requirements were expressly crafted for persistence. They included an 80% Estimated Time On Station (ETOS) for a group of BAMS platforms, over a period of 1 week (168 hours). That means UAVs in the air, within their assigned patrol zones at an estimated 900 nmi distance from launch, for 134 hours out of 168. That’s the minimum – the goal is 95% ETOS, or almost 160/168 hours.
The Navy saw BAMS UAVs employed within 5 “orbits” around the globe, with no more than 3 UAVs operating at the same time within each orbit. While this may make BAMS seem like a tiny program, consider the fact that all aircraft have fatigue lifespans measured in flight hours. Many fighters have lifespans of 10,000-12,000 hours. Transport aircraft can reach 30,000-40,000 hours, with major rebuilds along the way. Now consider the number of UAVs required to support flight profiles within those orbits, which are estimated to sum to 43,800 on-station flight hours/year, plus flight times to and from station for each mission. Over an expected program operational lifetime of about 20 years.
BAMS also has an unlisted, but critically important, program requirement. As UAVs proliferate in this role and begin undertaking long-range missions, they’ll require enough secure bandwidth to transmit large first-pass processed data sets to accompanying aircraft or ground stations. That cannot be provided from within the BAMS program, though communications relay packages on high-altitude BAMS UAVs will help military commanders on the surface. BAMS is in turn reliant on the USA’s Global Information Grid’s future security and capacity, in order to reach its full potential.
BAMS Options

Some nations use smaller business jet derivatives for maritime surveillance, and this option was closely considered by the Navy. The joint ACS (Aerial Common Sensor) program had potential dual-use features that could have made it a maritime surveillance supplement, as well as a SIGINT/ELINT (Signals & Electronic Intelligence & intercepts) platform to replace the Navy’s aging EP-3 Aries II fleet. The ACS program’s demise has taken that option off of the table for now. As it happens, however, the Navy had already chosen a different kind of companion for its P-8.
While business jets offered economy and numbers, the US Navy believed that unmanned UAVs could bring more to the long and oft-times tedious job of maritime surveillance. They can undertake very long-endurance flights of 30 hours or more, in part because they don’t have to carry processing stations and crew, or worry about aircrew endurance.
Northrop Grumman was always the favorite to win the BAMS competition. Its unarmed RQ-4 Global Hawk UAV had already proven itself in battlefield surveillance roles around the globe, and had been used as the Navy’s GHMD/BAMS-D maritime surveillance UAV testing and concepts research.
In contrast, the General Atomics MQ-9N Mariner’s main offered efficiency at much lower flight ceilings, up to 3,000 pounds of integrated weapons, and commonality with the Air Force’s MQ-9 Reaper strike UAV.
Boeing’s manned/unmanned G550 business jet was the 3rd major entry, offering the largest payloads, twin-engine redundancy, and compatibility with a civilian fleet.
BAMS: The MQ-4C Triton
MQ-4C Triton rollout
(click to view full)
The “RQ-4N” system chosen by the US Navy was based on the USAF’s RQ-4B Block 20 Global Hawks, but it incorporated a wide range of changes on the way to its unveiling as the MQ-4C Triton.
Sensors received the biggest overhaul. MQ-4Cs will have a more rounded belly housing for Northrop Grumman’s own 360-degree coverage AN/ZPY-3 AESA radar, as part of their Advanced Integrated Sensor Suite (AISS). Unlike conventional mechanically-scanned radars, AESA radars offer the ability to zoom in on several targets of interest, and they can do this without stopping the broader scan. That shift from Raytheon’s side-looking AESA radar used in the RQ-4B could have become a major risk factor, which was a big reason behind Northrop Grumman’s decision to field their new radar on a Gulfstream II BAMS test bed during the competition.
Beyond the radar, “Electronic Support Measures” systems that can pick-up, map, and identify radar emissions initially relied on Northrop Grumman’s LR-100, but Sierra Nevada’s Merlin ESM system was substituted in order to meet the program’s requirement for 360-degree, 300 nm/ 555 km coverage. In the visual spectrum, AISS includes an optical day/night surveillance and targeting turret.
Other sensors expected for the MQ-4C include a “due regard” radar and other systems that let them descend safely into potential air traffic over international waters (currently facing development difficulties), Identification Friend or Foe (IFF) in various modes, and of course sensor packages with additional SIGINT/ELINT equipment and other specialty mission packages. The UAV must be able to perform “first pass” processing of any data it receives, before sending it on to other ships, aircraft, and/or ground stations.
RQ-4N concept

Communications. A Ka-band Wideband Gapfiller satellite link will replace the commercial Ku-band link used by the USAF, in order to ensure 100% accessibility over long stretches of water. In addition, a pair of Ku-band and X-band datalinks have been added to the fuselage sides, to act as communications relays. Those relays, plus the addition of dual Common Data Links instead of single-CDL, and Link 16 capability UHF/VHF radios with HAVE QUICK and SINCGARS capability, will allow real-time data feeds to other Navy ships and aircraft. The US Air Force is reportedly considering this upgraded set for its own Global Hawks.
On the MQ-4C, an Automatic Identification System (AIS) receiver will allow the detection, identification, geo-location, and tracking of cooperative ships equipped with AIS transponders.
Mechanical. The need to have Navy UAVs descend and rise from altitude during over-water missions requires de-icing systems on the MQ-4C’s engine inlet, wings and tail. Strengthened wing structures were also deemed to be necessary.
One final mechanical issue concerns the Global Hawk design’s single turbofan engine. To cope with possible engine outages without losing these ultra-expensive UAVs, the USAF reportedly uses a combination of modified control software and alternate “glide-to” landing bases. When flying over vast ocean expanses, high altitude flight will be required, in order to keep the “glide-to” option alive.
BAMS: The Program
In April 2008, NAVAIR’s PMA-263 selected Northrop Grumman’s RQ-4N Global Hawk, which has since been re-designated MQ-4C. The FY 2014 budget cut the program from 70 (5 test + 65 operational UAVs) to a total of 66: 5 test + 61 operational UAVs.
BAMS Budgets from FY 2009 include:
Industrial team members include:
NGC performs Global Hawk sub-assembly work at its Unmanned Systems Center in Moss Point, MS, and anticipates performing final assembly at its St. Augustine, FL manufacturing center.
Triton’s Tactical Support Centers for command and control will be focused around the P-8A’s main bases: NAS Jacksonville, FL and NAS Whidbey Island, WA. Initial MQ-4C basing will include Ventura County Naval Base, at the Point Mugu, CA facility. Beyond that, NAVAIR has been tight-lipped, but reports have highlighted a few likely locations.
Andersen AFB on the island of Guam, which already supports some RQ-4 Global Hawks, is expected to become an important forward Pacific base, along with Hawaii and Diego Garcia. A fall 2013 agreement with Japan will provide for some Global Hawk basing in Japan itself, as a forward deployment from Andersen. It would be logical to expect MQ-4Cs as part of any eventual arrangement there. Australia’s Cocos Islands in the Indian Ocean have also been discussed as a way of relieving congestion at Diego Garcia, while keeping RQ-4 and possibly MQ-4 UAVs closer to sea lanes and countries of interest. The required infrastructure upgrade is an issue for Australia, however, and much may depend on Australia’s own purchasing decisions regarding the MQ-4C.
Sigonella AB in Sicily, Italy is already a key Global Hawk base, and it will also house NATO’s RQ-4B Block 40 AGS fleet. It’s likely to serve as the Triton’s hub to help cover Europe, the Middle East, and Africa, but other bases in that region would make the fleet much more effective. Advanced spy planes have already flown out of the UAE, which would be very convenient for covering the Middle East and western Indian Ocean. Portugal’s Azores was a key naval air waystation for decades until NAF Lajes was inactivated in the late 1990s, and would be well positioned for operations to cover Africa’s oil-rich and piracy rich western coast. It’s worth keeping an especial eye on developments in those 2 locations.
BAMS: The International Angle

The US Navy has been using the RQ-4 Global Hawk as a demonstration and proving platform to refine requirements and concepts of operations for BAMS, under the GHMD(Global Hawk Maritime Demonstrator) program. Even so, UAVs aren’t widely used for maritime surveillance just yet.
Beyond America’s shores, India has successfully used Israel’s Heron and Searcher II UAVs for coastal patrol as well and overland surveillance; UAVs from their 2005 follow-on Heron order have also been pressed into service along the coasts. To the southeast, Australia has undertaken successful trials with the General Atomics’ Mariner UAV for Coast Guard duties along its resource-rich Northwest Shelf. In the Great White North, Canada is evaluating UAVs for a maritime surveillance role under its JUSTAS program; Phase 2 could even include arctic surveillance out of Goose Bay, Labrador. IAI/EADS’ Eagle UAV, and General Atomics’ Altair high-altitude UAV derived from the MQ-9 Reaper, have already been tested as part of requirements definition.
Every one of these countries could eventually end up involved in the BAMS program.
P-8i test flight

India’s MPA competition chose the “P-8I” as their next maritime patrol aircraft. With BAMS integration already scheduled for their chosen platform, a nation that sees its responsibilities stretching across the Indian Ocean from the Straits of Malacca near Singapore, to the Persian Gulf, and down to Madagascar, has obvious uses for the compatible Triton long-range, long-endurance UAV platform.
India seems to agree with this logic, but a treaty that it hasn’t signed is in the way. MTCR was originally aimed at limiting cruise missile exports, but a jet-powered UAV shares enough characteristics to create problems. Discussions are ongoing.
The Canadians have also been approached as possible partners in the P-8A Poseidon program, as a future replacement for their P-3/CP-140 Auroras. Thus far, they have made no commitments. Meanwhile, Northrop Grumman is offering them an RQ-4 variant called “Polar Hawk” for Arctic patrol, incorporating some MQ-4C features like de-icing. The vast expanses of Canada’s north make the speed of a jet-powered UAV very attractive, Northrop Grumman will have to beat General Atomics, which is offering its jet-powered Predator C as well as its slower MQ-9 UAV. If NGC can win, adding more Global Hawks for other missions would become easier.
AP-3C: who’s next?

Australia went even further, and made itself a partner in BAMS via its AIR 7000 program. First Pass Approval was given in September 2006, and a Project Agreement was signed on Jan 13/07. Australian Embassy personnel have attended NAVAIR PMA-263 industry days, Australian technical experts are part of the BAMS integrated project teams, and NAVAIR’s BAMS RFP now includes an “Australian Unique Option” section. BAMS had passed its Milestone B “go/no-go” decision, and was analyzing unique Australian requirements before an expected Australian second-pass approval decision that could begin Australian BAMS production in 2012, and achieve Initial Operating Capability in 2015.
In 2009, however, Australia chose to drop out of the BAMS program, with sources citing both operational stress over the P-8A’s similarly-timed introduction, and fiscal pressures. They could still choose to drop back in, and their May 2013 Letter of Request for technical information is a step in that direction. The trade-off is that they’ll be looking at more of a finished product, with less scope for free-of-charge changes.

April 9/14: Sense-and-Avoid. The US Navy still wants to place this technology on the Mq-4C, not least because it will be required for low-altitude flying in many areas of interest. The problem is that miniaturizing the Exelis AESA radar turned out to be much harder than they thought, to the point where they had to pause and look at other options (q.v. Aug 13/13).
Above 18,000′, standard ADS-B (Automatic Dependent Surveillance-Broadcast) and TCAS (Traffic Collision Avoidance System) “due regard” systems can keep the UAV from getting too close to civilian aircraft, and to many military airplanes as well. Below that altitude, ground and ship-based radars can be used, and something might be doable using aerial radars like AWACS plus datalinks. On the other hand, the whole point of the MQ-4C is to survey areas where those assets aren’t already on patrol.
This is a serious issue for UAVs generally, so it may be worth biting the bullet and investing the funds required to solve the problem. It may even be a hard and significant enough problem to justify DARPA’s involvement. Sources: USNI, “Navy Expanding Search for ‘Sense and Avoid’ Technologies for Triton”.
March 31/14: GAO Report. The US GAO tables its “Assessments of Selected Weapon Programs“. Which is actually a review for 2013, plus time to compile and publish. The program dashboard and timeline have been updated accordingly, though the Navy’s program office has authorized NGC to develop a new target baseline and schedule with increased costs and schedule delays. That isn’t represented in the charts yet. The program has 3 big technical risks left.
One is software, thanks to about 1.6 million lines of new code in an 8 million line system. There are another 2 software phases left before operational evaluation begins in January 2016.
Another is navigation. In September 2013, the Global Hawk program experienced an anomaly with a navigation system, suspending the derivative Triton’s test flights until a workaround was identified. The problem remains unfixed.
Finally, the air-to-air “sense and avoid” radar subsystem (q.v. Aug 13/13) for operating in civil airspace has hit a wall, and delayed the program by about 1 year.
March 28/14: Infrastructure. The Guam MACC Builders joint venture in Honolulu, HI wins a $45.5 million firm-fixed-price task order under a multiple-award construction contract. they’ll design and build a high bay maintenance hangar to support MQ-4C forward operations and maintenance at Andersen AFB, Guam. That involves scheduled inspections, airframe repairs, pre- and post-flight operations, as well as technical order compliance and aircraft modifications. A pair of unexercised options could raise the total to $46.7 million.
All funds are committed immediately, using a combination of FY 2010 and FY 2014 budgets. Work will be performed in Yigo, Guam, and is expected to be complete by April 2016. Six proposals were received for this task order by NAVFAC Pacific at Joint Base Pearl Harbor-Hickam, HI (N62742-10-D-1309, #0003).
March 24/14: Testing. The Mq-4C has completed the envelope expansion portion of its test flights (q.v. Jan 6/14). Sources: NGC, “Northrop Grumman, U.S. Navy Complete Initial Flight Testing of the Triton Unmanned Aircraft System”.
March 4/14: FY15 Budget. The USN unveils their preliminary budget request briefings. Precise figures are only offered later, but the Navy does offer planned purchase numbers for key programs between FY 2014 – 2019.
MQ-4C Triton production was supposed to start with 3 UAVs in FY15, but that isn’t happening because the program is behind. In addition to the late start, the Navy’s mid-term budgets will also slow the production ramp-up. Production begins in FY16 instead with 4 (unchanged), and continues with 4 in FY17, 4 in FY18 (-2), and 4 in FY19 (no previous comparable). Subsequent documents show that the program’s overall budget doesn’t change all that much, but around $400 million is added to R&D, and costs per UAV rise a bit. Those costs may drop a bit in future, if Australia buys in as expected.
The immediate pause makes sense, but the vastness of the Pacific and supposed importance of the “Pacific Pivot” don’t seem to be getting a lot of weight in the Navy’s 5-year plan – which also cuts P-8 sea control aircraft, and E-2D Advanced Hawkeye AWACS. Sources: USN, PB15 Press Briefing [PDF].
Jan 6/14: Testing. Northrop Grumman announces that the MQ-4C is half-way through the envelope expansion portion of flight testing. It’s still early days, with the longest mission being just 9.4 hours at up to 50,000 feet. Sources: NGC, “Multimedia Release — Northrop Grumman, Navy Complete Nine Flights of Triton Unmanned Aircraft System”.
Nov 4/13: Northrop Grumman Corp. and Triumph Aerostructures’ Vought Aircraft Division have finished initial MQ-4C structural strength testing at Vought’s Dallas, TX facility. Which means torturing the wings and bending them 22% beyond US Navy structural requirements, in hopes they don’t break or permanently deform. This isn’t just a life-span issue. It’s a very immediate requirement whenever a Triton UAV has to drop down for a closer look at something, possibly through inclement weather.
Vought was involved in these tests because they produce Global Hawk family wings. A fatigue test of the entire airframe will begin in 2017. Sources: NGC, Nov 4/13 release.
Oct 7/13: The Whidbey News-Times reports that the MQ-4C’s Tactical Support Centers for command and control will be placed at the 2 main P-8A support centers: NAS Jacksonville, FL and NAS Whidbey Island, WA. It seems like a fairly obvious operational conclusion, but it was also the consensus of environmental assessments.
“Four of the MQ-4C Tritons will be based out of Ventura County Naval Base in California [by 2016], but the existing P3 tactical support center at Whidbey Island Naval Air Station will be expanded to support both the P8-A and the Triton…”
Sources: Whidbey News-Times, “New drone supports P-8A Poseidon”.

MQ-4C: 1st flight

Sept 9/13: Australia. Australia’s Liberal Party is back in power after a convincing electoral win over Labor. While the new government’s commitment to 2% of GDP for defense spending is a broad positive for industry, their level of commitment to the MQ-4C weakened:
“The acquisition of unmanned aerial vehicles will be dependent on the advice of the chief of the Defence Force and service chiefs, as well as a clear cost-benefit assessment that demonstrates the value of these aircraft.”
Triton is likely to pass that test, but this is a step back from earlier statements to the effect that Triton was a high-priority buy. Sources: Australian Liberal Party, “The Coalition’s policy for Stronger Defence” | Defense News, “New Australian Leadership Pledges to Boost Defense Spending”.
Aug 14/13: Infrastructure. Small business qualifier Whitesell-Green, Inc. in Pensacola, FL wins a $15.9 million firm-fixed-price contract to build a BAMS Mission Control Complex at NAS Jacksonville, FL. It will be a freestanding 2-story structure with two Electromagnetic Interference Shielded Mission Control Systems, a Tactical Operations Center with sensitive compartmented information facility spaces, and numerous roof-top mounted antennas. This project will also renovate some interior spaces, including a reconfigured command suite, systems reconfiguration, and in some cases finish upgrades. Finally, additional antennas will be built at a remote site south of the new facility.
All funds are committed immediately. Work will be performed in Jacksonville, FL, and is expected to be complete by December 2014. This contract was competitively procured via Navy Electronic Commerce Online, with 8 proposals received by NAVFAC Southeast in Jacksonville, FL (N69450-13-C-1258).
Aug 13/13: Sense-and-Avoid. BAMS Program manager Navy Capt. Jim Hoke says that ITT Exelis’ radar-based Airborne Sense And Avoid system (q.v. Aug 10/12) is “behind schedule,” so the Navy has “made a decision to pause on the capability right now” and has stopped work. Hoke says that he understands how important this capability is for operations in crowded airspace and allied countries (vid. May 29/13, May 14/13), especially given the MQ-4C’s operational need to descend to lower altitudes at times for a closer look, but “all options are on the table.” If the system really is seen as critical, that could mean a re-compete of the sub-program, or the Navy could decide to join the USAF’s ABSAA effort (q.v. July 30/12).
Re-competes can be problematic, but this may be a case where the circumstances are attractive. The natural scalability of AESA radars means that any successful implementation could be applied to other large UAVs, from NATO’s planned RQ-4 Block 40 AGS Global Hawk variant, to smaller MALE UAVs like the MQ-9 Reaper or MQ-1C Gray Eagle. That’s a significant and growing opportunity for the winning contractor, with follow-on “proven leader” opportunities around civil UAV use. This dynamic could attract firms willing to invest up front with low bids or substantial resources, and the base ABSAA field is a mature one thanks to civil aircraft. Breaking Defense.
Sense-And-Avoid radar on hold
June 25/13: Australia. With an election coming, the MQ-4C Triton seems secure, as both parties remain committed to it. Reuters:
“There’s not a lot of new money in our policy, (but) we are going into Broad Area Maritime Surveillance, the Triton,” said conservative defense spokesman David Johnston, who is likely to become defense minister following the September 14 elections…. “This is about maritime security and surveillance in the Indian Ocean,” a senior Labor insider with close knowledge of defense planning said. “This is a force multiplier. It’s better to think of Triton as a mobile satellite we can steer around the Indian Ocean,”
June 14/13: Sense-and-Avoid. BAE Systems’ AN/DPX-7 Reduced Size Transponder (RST) Indentification Friend-or-Foe system flies on the MQ-4C for the 1st time. IFF transponders broadcast coded location signals to friendly aircraft, and also receive signals from civil and military aircraft around them. They aren’t a complete solution to the problem of operating in crowded airspace, but with the right programming and UAV flight system connections, they can help. Unmanned Systems Technology.
May 29/13: Sense-and-Avoid. Answers from Northrop Grumman clarify the MQ-4C’s sense-and-avoid systems:
“Triton’s due regard radar is meant to provide safe separation of aircraft while the system is in flight at lower altitudes. The U.S. Navy’s mission requires that Triton be able to descend to lower altitudes to make closer identification of surface vessels. The radar is still in development and would be flight tested on Triton at a later date. This is a Navy requirement to ensure that the Triton UAs can safely operate over international waters.”
With respect to ICAO certification issues, Northrop Grumman would only say Global Hawk is the first unmanned aircraft system to achieve a military airworthiness certification. That can only be used to fly a pre-approved, monitored flight plan in American civil airspace, and then only if a specific supplemental FAA certificate of authorization (COA) is granted in advance. Whether this level of certification will work at NAS Sigonella, Italy is a question that the US Navy will need to answer. “Saigon” has already been a base of operations for RQ-4B Block 20 Global Hawks, which lack any form of collision avoidance system. The question is how restricted future MQ-4C flight options would be, absent further certifications.
May 22/12: Fly! The MQ-4C has its 1st flight. The flight was originally scheduled for March 2013, but all goes well, The Navy and Northrop Grumman flight test team conducts an 80 minute flight from Palmdale, CA, reaching up to 20,000 feet while remaining within restricted airspace.
Northrop Grumman says that additional flight tests will take place from Palmdale to mature the system, before it’s flown to the main flight test facility at NAS Patuxent River, MD, later this year. It will be interesting to see if it flies there under its own power, or is disassembled and carried in a heavy-lift aircraft. Even the carrier-based X-47B stealth UCAV had to travel to Pax River on a truck, because the FAA wouldn’t certify it for flight in civil airspace. The MQ-4C is designed with a sense-and-avoid system, so the FAA could conceivably grant it a waiver. US Navy Capt. Jim Hoke is the current Persistent Maritime UAS office (PMA-262) program manager, and it will be up to him to oversee transportation arrangements. US Navy | US NAVAIR | US Navy Live | NGC.

May 22/13: XP – 7. Northrop Grumman Aerospace Systems in Bethpage, NY receives a $15.3 million cost-plus-award-fee contract modification to upgrade some MQ-4C Triton components from Windows XP to Windows 7. Microsoft is ending support for XP, hence the shift, which will happen in quite a few US military programs. We wonder about the security implications of using Windows at all in an incredibly expensive autonomous system, but that’s a separate discussion.
Work will be performed in Hollywood, MD (33.5%); Bethpage, NY (25.8%); Rancho Bernardo, CA (15.6%); San Diego, CA (12.7%); Salt Lake City, UT (9.8%); Stillwater, OK (1.10%); Melbourne, FL (1.0%) and Van Nuys, CA (.05%), and is expected to be complete in April 2014. Funds will be committed as needed by US Naval Air Systems Command in Patuxent River, MD (N00019-08-C-0023).
May 16/13: Australia. Australia’s government announces that they’re sending a formal Letter of Request to the USA for the MQ-4C Triton UAV. The letter will become a Foreign Military Sales Technical Services Case with the United States Navy to obtain detailed cost, capability and availability information. They emphasize that they haven’t picked the MQ-4C yet for AIR 7000 Phase 1B, but they didn’t announce letters of request for any other platforms that might compete with the Triton, like General Atomics’ MQ-9. Which may have separate opportunities of its own:
“As also outlined in the 2013 Defence White Paper, Defence will analyse the value of further investment in unmanned aircraft for focused area, overland intelligence, surveillance and reconnaissance, including for use in border security operations. This will include the potential expansion of the role of these assets in the ADF to include interdiction and close air support, subject to policy development and Government consideration.”

May 14/13: Euro Hawk falls. Germany has decided to end the Euro Hawk UAV project, after spending EUR 562 million on system development and test flights. Not only would it cost hundreds of millions more euros to attempt EASA/ICAO flight certification, but German authorities reportedly lacked confidence that they would receive a certification at the end of the process. Rather than pay another EUR 600 – 700 million for additional UAVs and equipment, and an equivalent amount to attempt EASA certification, Germany will attempt to find another path.
The remaining questions fall instead on Sigonella, Italy, where NATO and the USA plan to base MQ-4C Tritons, and RQ-4B AGS Global Hawk Block 40s. German lawmakers are raising those questions, and some are advocating pulling out of NATO’s AGS as well.
March 4/13: Australia. Aviation Week reports that Australia may want more P-8As, at the possible expense of its MQ-4C companion UAVs:
“The RAAF is quietly making a case for 12 Poseidons, arguing that eight would not be enough to cover the vast oceans surrounding the continent. And the unmanned requirement is now described as “up to” seven high-altitude, long-endurance aircraft, potentially reducing Northrop Grumman’s opportunity. At the same time the air force sees an argument for a supplementary drone, possibly the Predator, to take on some of the electronic-intelligence missions that would otherwise fall to the Poseidons and Tritons.”
This is a bit of a head-scratcher. The stated purpose of sustained ocean coverage would be better served by adding another orbit of 3-4 MQ-4Cs (to 10-11), using the P-8s as more of a fleet overwatch and contact response force. Likewise, it makes little sense to use a different UAV for ELINT/SIGINT collection, especially the slow and shorter-range MQ-9. Rather, one would use the MQ-9s in nearer-shore maritime and EEZ patrols, along the lines of the 2006 Northwest Shelf experiments, in order to free up MQ-4Cs for longer-range expeditions over strategic corridors, and the ELINT/SIGINT mission they will be equipped for as of Increment 3.
Feb 22/13: Australia. Australia may have officially dropped out of the BAMS development phase (vid. March 2/09 entry), but News Corp. reports that Defence Minister Stephen will sign a formal export letter of request for the MQ-4C at the 2013 Australian International Airshow. Australia has remained part of the P-8A program for a manned sea control jet, so the MQ-4C is a natural pairing.
The purchase budget is expected to be $A 2-3 billion, but it may be overshadowed by Australia’s expected announcement that they will buy another 24 F/A-18F Super Hornets. News Corp.
Feb 7/13: India. Northrop Grumman’s MQ-4C business development lead Greg Miller tells Shephard’s UV Online that India’s RFI for a High Altitude, Long Endurance maritime surveillance platform holds promise:
“They want to follow the US model; P-8 and Triton…. The Indian Navy agrees with the US’ requirements, which exactly fits our sweet spot.”
Their problem is the same problem facing South Korea: the Missile Technology Control Regime (MTCR), which bans the export of cruise missiles or unmanned vehicles with certain range and payload limits. India hasn’t signed MTCR, but the issue needs to be resolved at a government-to-government level. UV Online.
March 28/13: GAO Report. The US GAO tables its “Assessments of Selected Weapon Programs“. Which is actually a review for 2012, plus time to compile and publish. With respect to BAMS, they say the design is stable, with 99% of drawings releasable to manufacturing. Software code is a challenge, as are the UAV’s new-design wings. Disruptions to the USAF’s Global Hawk programs aren’t expected to affect schedule, but fewer UAVs produced does drive up the cost per UAV. Excerpts:
“The second development aircraft, the first aircraft with a full sensor suite and the air-to-air radar subsystem, is nearing completion and is expected to begin testing in 2013…. However, the program poses a significant software development challenge, utilizing nearly 8 million lines of code, more than 20 percent of which will be new. Much of the remaining software is derived from Global Hawk; however, officials noted that integration and testing of this code is taking longer than expected. Officials also noted that delays in the manufacturing of the aircraft wing as well as corrections to software during integration of subsystems are the primary reasons for a delay in the program’s operational assessment and production decision….”
Jan 17/13: DOT&E testing. The Pentagon releases the FY 2012 Annual Report from its Office of the Director, Operational Test & Evaluation (DOT&E). The MQ-4C Triton is included, and the program is falling behind. The plan was to conduct an Operational Assessment in June 2013, leading to a Milestone C decision in October 2013.
Unfortunately, a combination of UAV mission computer software stability problems, and radar performance issues identified in tests with Northrop Grumman’s radar-equipped Gulfstream-II jet, delayed flight testing from May 2012 to “at least” January 2013. The program has also “deferred development and testing of [unspecified] air vehicle and sensor capabilities until after Milestone C in order to reduce current test schedule pressures.”
The plan to reach Milestone C by October seems less and less likely, especially given additional “ground test delays encountered in [fall 2012].” Northrop Grumman will also need to resolve issues with software stability for both the mission computer and ZPY-3 MFAS radar, radar detection and tracking consistency, and radar image quality.
Jan 8/13: Company bird. Northrop Grumman is spending its own money to build and equip its own MQ-4C UAV, complete with the same sensor set the Navy will get. The UAV is under construction, and just had its wings and fuselage joined.
It isn’t the first time Northrop Grumman has done this; indeed, in many ways it’s just a further extension of the company Gulfstream-III business jet test bed, which has been flying since before the development contract was awarded. Initial missions for the company’s UAV will involve supplementing Navy tests, in order to help the team reach their goal of operational UAVs by late 2015. Eventually it will become a platform for demonstrations, integration of different sensors that the US Navy or other customers are interested in, and system performance improvement testing.
1 MQ-4C for Northrop Grumman
September 2012: Testing. A 2nd MQ-4C is added to ground test efforts, with a focus on control software and subsystems. NGC.
Aug 10/12: Sense-And-Avoid. ITT Exelis exhibits their BAMS airborne sense-and-avoid (ABSAA) radar for the first time, at the Unmanned Systems North America conference in Las Vegas. It’s the 1st U.S. Department of Defense ABSAA/ ICAO “due regard” radar program of record, with flight testing expected to start in Q1 2013.
Aug 10/12: Sense-And-Avoid. ITT Exelis exhibits their BAMS airborne sense-and-avoid (ABSAA) radar for the first time, at the Unmanned Systems North America conference in Las Vegas, NV. It’s the 1st US Department of Defense ABSAA/ ICAO “due regard” UAV radar program of record, with flight testing expected to start in Q1 2013.
Their “SkySense 2020H” can be adapted for other UAVs, but the self-contained, 50 pound MQ-4C configuration involves 3 thin-tile AESA array panels mounted at the front of the UAV. It operates in the Ku-band with an 8-10 nmi range, and a 110 degree wide x 30 degree high field of view. AESA radars are flexible if the right software is installed, and Exelis is also looking at using SkySense for weather radar and communications functions. AIN Online.
July 2012: Testing. 1st MQ-4C Triton begins ground tests. NGC.
July 30/12: Sense-And-Avoid. The USAF Research Laboratory (AFRL) has been working on a sense-and-avoid system called Multiple Intruder Autonomous Avoidance (MIAA) since 2008, and is about to conduct the final test phases using a Calspan-operated Learjet as an RQ-4 surrogate. Co-operative commercial aircraft are dealt with using standard methods: a traffic collision avoidance system and ADS-B. Aviation Week says that for non-cooperative aircraft:
“The flights will evaluate collision-avoidance algorithms and a new electronically scanned sense-and-avoid radar, as well as a new technique to perform passive target ranging from the two-dimensional imagery provided by electro-optical sensors.”
Once they’re done, MIAA will become move to EMD system development as part of the USAF’s Global Hawk program. The Navy and Army are both interested, however, and are partners in this effort. A Global Hawk flight is planned in 2015, with Initial Operating Capability planned in 2017. Aviation Week, via NPS.EDU: “Sense-And-Avoid System To Transition To Global Hawk”.
June 14/12: Triton unveiled. Northrop Grumman and US NAVAIR unveil the 1st MQ-4C at Northrop Grumman’s Palmdale, CA plant, and announce its operational moniker: “Triton.” In mythology, Triton was Poseidon’s son, the messenger of the sea. US NAVAIR | Northrop Grumman.

June 11/12: BAMS-D Crash. An RQ-4A BAMS-Demonstrator Global Hawk crashes into a marshy tributary of Maryland’s Nanticoke River, during a routine training flight from Naval Air Station Patuxent River. There were no injuries to civilians and no property damage, but the crash site has been blocked to recreational boat traffic while the agency investigates. The crash leaves 4 UAVs in the program: 3 for testing, tactics, and doctrine development in the USA, and 1 deployed abroad with the 5th fleet. CNN | Wired Danger Room | WBOC.
May 30/12: Canada. Northrop Grumman Corporation and Canada’s L-3 MAS announce plans to offer Canada a “Polar Hawk” UAV for surveillance of Canada’s arctic land and seas.
As one might guess, it will need to share a number of structural features like strengthened wings and improved de-icing with the MQ-4C Triton. Improved satellite communications, with specialized receivers for polar-orbit satellites, will also be necessary. Sensors aren’t discussed, but the accompanying picture shows a conventional Global Hawk shape, without the AN/ZPY-3 MFAS. NGC.
May 29/12: More SDD. Northrop Grumman Aerospace Systems in Bethpage, NY receives a $32.8 million cost-plus-award-fee contract modification, for BAMS system development and demonstration. This modification funds a maintenance concept change that will develop a logistics management I.T. system, and improve the transition from contractor logistics support to organic military maintenance by the Navy. Funding will be committed as needs arise.
Work will be performed in Bethpage, NY, (74.54%), Rancho Bernardo, CA (20.82%), Melbourne, FL (4.59%), and Palmdale, CA (0.05%); and is expected to be complete in September 2015 (N00019-08-C-0023).
January 2012: Testing. The Pentagon approves the MQ-4C Triton Broad Area Maritime Surveillance Test and Evaluation Master Plan (TEMP), which will guide efforts to bring the UAV to a successful Milestone C decision, and into low-rate initial production. DOT&E.

April 25/11: ZPY-3. Northrop Grumman announces the start of system tests for the BAMS UAV’s Multi-Function Active Sensor (MFAS) maritime surveillance radar. MFAS will use a 2-dimensional radar with both electronic and mechanical scanning.
Northrop Grumman’s Aerospace Systems sector facility in San Diego, CA is expected to take delivery of the 1st MFAS in June 2011, following ongoing radar software mode development and hardware synchronization and integration activities. A 2nd radar is slated for delivery in September 2011, and risk reduction flight tests on board the company’s Gulfstream II test-bed expected before year end.
March 16/11: Northrop Grumman Corporation completes the 1st of 3 BAMS fuselages under the SDD phase. The MQ-4C fuselage will undergo final assembly and system checkout at the company’s Palmdale, CA facility, ahead of its first flight in 2012. NGC.
March 7/11: CDR. Northrop Grumman announces that the BAMS program completed its system-level Critical Design Review (CDR) with the U.S. Navy in February 2011 – but it is not fully closed yet. The government and Northrop Grumman teams will be working to close out issues raised during the CDR, before it can be officially over.
The system-level full CDR sets the initial product baseline for the MQ-4C system, and was preceded by 10 subsystem and segment CDRs. Northrop Grumman VP and BAMS program manager Steve Enewold says that the SDD phase’s first 2 UAV fuselages are being built at Moss Point, MS, and the first will ship in April 2011 to Palmdale, CA for final assembly. The next major milestone is Test Readiness Review, planned for fall 2011. First flight is expected in 2012, and Enewold says the program continues to meet its acquisition baseline cost, schedule and performance requirements.
Feb 18/11: Sense & Avoid. Northrop Grumman Aerospace Sector’s Battle Management & Engagement Systems Division in Bethpage, NY receives a $25.6 million cost-plus-fixed-fee delivery order to develop an “airborne sense and avoid capability for the Broad Area Maritime Surveillance (BAMS) unmanned aircraft system in support of the Navy and Air Force.” The goal is a TRL 7 system, i.e. a prototype tested in operationally-relevant conditions.
The wording is interesting, as it implies that USAF RQ-4A/B Global Hawks will also be fitted with this capability. As they should be. Sense and avoid technologies are used in commercial aircraft, in order to prevent mid-air collisions. While flying at 60,000 feet will go a long way toward zero collisions, the UAVs do not begin at that altitude, and BAMS in particular will not spend all of its mission time at that level. Throw in funded experiments like aerial refueling between 2 Global Hawk UAVs, and expectations that the stratosphere is likely to be more crowded in future, and the necessity of sense & avoid technologies becomes clearer. To this point, however, the US Navy and USAF have pursued different technology approaches: an ITT-supplied air-to-air radar and ADS-B cooperative surveillance for the Navy, and a multi-sensor “multi-intruder autonomous avoidance (MIAA)” USAF project that uses 3 electro-optical cameras, a low-power radar, and the civil TCAS traffic collision avoidance system.
Work to reconcile those approaches into a common prototype will be performed in Bethpage, NY (50%) and San Diego, CA (50%), and is expected to be complete in November 2012. $7,368,022 will expire at the end of the current fiscal year, on Sept 30/11 (N00019-10-G-0004). See also: Aviation Week.
Feb 9/11: Northrop Grumman announces a $3.3 million contract to participate in the Unmanned Aircraft System (UAS) Control Segment (UCS) Architecture Working Group (UCSWG), sponsored by the Office Secretary of Defense’s (OSD) Unmanned Warfare Office.
The UCSWG is an open technical standards committee consisting of industry and government representatives from each UAS program of record, several emerging UAS programs and small businesses. The objective of the UCSWG effort is to define a common UAS control station architecture based on standard data models and service interface definitions to enable interoperability, scalability and adaptability of UAS ground stations.
Sept 1/10: New designation. A ceremony at Northrop Grumman’s Moss Point, MS manufacturing facility marks the beginning of RQ-4N BAMS UAV construction.
It is also the first official mention of the platform’s MQ-4C designation. Northrop Grumman spokesman Jim Stratford explains that “M” stands for “Multi-mission,” referring to planned expansion to communications relay and SIGINT missions. The “C” is because there are significant differences from the USAF’s RQ-4B Block 20/30/40, such as anti-icing and sense/avoid capabilities. The “RQ-4N” was Northrop Grumman’s designation during the BAMS competition, but it was never official. Northrop Grumman.
