The U.S. Navy continues to make use of MQ-1 Predators as test and training assets, eight years after the U.S. Air Force retired the iconic drones. TWZ was first to report that the Air Force was looking at transferring some of its remaining Predators to the Navy back in 2019, but it was unclear what came of those discussions in the end. Now we know.
The Air Force officially retired the MQ-1 in 2018. At that time, the service still had dozens of these drones in its inventory. More than 50 Predators were heavily cannibalized for parts they shared with their newer cousin, the MQ-9 Reaper. A number of demilitarized examples were also put on display. Today, 15 MQ-1s remain in storage at the boneyard at Davis-Monthan Air Force Base in Arizona, and are technically the property of the National Museum of the U.S. Air Force. Then there’s the matter of the MQ-1s that went to the Navy.
“In 2019, Naval Air Warfare Center Weapons Division (NAWCWD) received 20 MQ-1 aircraft from the U.S. Air Force,” a spokesperson for NAWCWD, part of the Navy’s Naval Air Systems Command (NAVAIR), confirmed to TWZ. “These aircraft were redesignated as NMQ-1Bs to support our mission.”
The new nomenclature here is notable. In the U.S. military’s joint service designation system for aircraft and missiles, the prefix “N” refers to platforms that have been modified in some way, typically for testing purposes, that is not readily reversible. One of the better-known examples of this is the Air Force’s secretive NT-43A radar cross-section measurement platform, a heavily modified Boeing 737-200 with a completely new and enlarged nose, as well as a huge radome extending from the tail. Other “N” aircraft that various branches of the U.S. military have operated over the years have had far less dramatic modifications. How exactly the NMQ-1B configuration differs from a typical MQ-1B is unclear.
“NAWCWD is an RDT&E [research, development, test and evaluation] command and the platforms were acquired to support our targets department,” they added when asked for more information. “The NMQ-1B platform is being used for test and training. We have nothing further to provide at this time.”
TWZ had reached out to the Navy for more details after the Air Force had also confirmed the transfer of the MQ-1s. We had asked the Air Force about the status of any Predators still in its inventory after U.S. Central Command (CENTCOM) confirmed the loss of an “MQ-1” to Iranian fire at the end of May. By all indications, what Iran shot down was actually a U.S. Army MQ-1C Gray Eagle, a design that evolved from the Predator, but that is distinctly different.
When the Air Force retired the MQ-1, the service still had dozens of airworthy examples. TWZ pointed out at the time that at least a portion of them could end up as targets for air-to-air and surface-to-air weapons, as well as sensor testing and other weapons testing. The fact that NAWCWD says it is still using the drones today would seem to point more to the latter than the former, though anti-air missile testing does not necessarily have to entail the destruction of the target.
For instance, certain kinds of testing of some missile seekers can be done without it ever leaving a rail on an aircraft or a launcher on the ground. The Navy and Air Force test communities also use specialized podded systems to support the development and evaluation of new and improved seekers for anti-air missiles, something we have explored in detail in the past. Even live fire tests do not always result in the target being destroyed if that is not the intended outcome. Just by removing the warhead, missiles will still pass within lethal distance with their proximity fuzes being triggered to confirm a simulated kill. The missile will fly on, and the target will survive to live another day.
As noted, at least based on the NMQ-1B designation, the Navy’s Predators have been altered in some significant way. One possibility is that they have been modified to be able to mimic an array of different radar, infrared, and/or other signatures. In this way, a Predator could offer a lower-cost and long-endurance flying asset capable of replicating a variety of aerial threats to support testing and training requirements. The U.S. military already uses smaller crewed aircraft as surrogates for cruise missiles and long-range kamikaze drones, as can be seen in the TWZ video below. This is in addition to target drones specifically built for this purpose.
The NMQ-1Bs could also be modified in a variety of other ways to support more specific NAWCWD requirements, or to make them more adaptable to meet changing demands. The standard MQ-1B variant also features two underwing hardpoints that could be used to carry various stores, such as countermeasures and small munitions. This would further expand the Predator’s flexibility as a test and training asset from one sortie to the next. Being able to more readily modify or swap out the drone’s internal systems, as well as the software running them, would also be a boon for its current role.
Despite being housed within NAWCWD’s targets department, depending on their current configuration, the NMQ-1Bs could also help monitor missile and other test activities, or even act as signal relays. Before armed MQ-1 versions arrived, RQ-1 Predators were already flying surveillance and reconnaissance missions using infrared and electro-optical full-motion video cameras in turrets under their noses. The drones could also be fitted with small radars with synthetic aperture modes capable of capturing still imagery, even through cloud cover, smoke, and dust, and at night.
News that the Navy is still using Predators for testing and training purposes certainly comes at a time when drone threats at home and abroad have become firmly top of mind for the U.S. military. For American authorities, the ability of long-range kamikaze drones, in particular, to hold prized assets at risk was just highlighted by the latest conflict with Iran. Russia’s ongoing war against Ukraine, as well as other conflicts globally in recent years, have also underscored this reality. For years now, TWZ has been calling attention to the dangers that various tiers of uncrewed aerial systems pose, which are only set to continue to expand in scale and scope.
Confirmation that NAWCWD continues to operate a fleet of NMQ-1Bs also comes amid a surge in U.S. military flight testing activities, and commensurate demand for supporting test assets. This is being driven heavily by a flurry of next-generation aircraft and missile developments, as well as efforts to modernize existing platforms to keep pace.
Around their retirement, there were rumors that the remaining MQ-1 fleet could be used to test cooperative swarming capabilities, including hardware, software, and communications networks. There is no hard proof that this occurred, but it seems quite plausible considering the timing and how well-known and adaptable the Predator was at the time.
Using surrogate drones in the development of autonomy agents, teaming architectures, and swarming capabilities is now a very well-established practice. The big question is that if these Predators are still flying, or at least have been since their retirement, how is it that we have not caught a glimpse of them? One answer would be that this work was done at clandestine test facilities like Area 51 or even less secretive but still somewhat remote locales. If this is the case, these aircraft likely have historic significance, paving the way to the autonomous air combat revolution currently underway.
Overall, how much longer the Navy might continue to make use of the NMQ-1Bs remains to be seen. The service’s test community has already given the iconic Predator nearly a decade of extra life.
