The contract provides for the design, development, fabrication, test, delivery, and support of four MQ-25A unmanned air vehicles, including integration into the carrier air wing for an initial operational capability by 2024.

“MQ-25A is a hallmark acquisition program,” said Assistant Secretary of the Navy for Research, Development, and Acquisition James F. Geurts in the announcement.

“This program is a great example of how the acquisition and requirements communities work hand in hand to rapidly deliver capabilities to our Sailors and Marines in the fleet.”

When operational, MQ-25 will improve the performance, efficiency, and safety of the carrier air wing and provide longer range and greater persistence tanking capability to execute missions that otherwise could not be performed.

“This is an historic day,” said Chief of Naval Operations Adm. John Richardson.

“We will look back on this day and recognise that this event represents a dramatic shift in the way we define warfighting requirements, work with industry, integrate unmanned and manned aircraft, and improve the lethality of the airwing — all at relevant speed. Everyone who helped achieve this milestone should be proud we’re here. But we have a lot more to do. It’s not the time to take our foot off the gas. Let’s keep charging.”

In 2016, after many delays over whether the ( Unmanned Carrier-Launched Airborne Surveillance and Strike) UCLASS aircraft would specialise in strike or intelligence, surveillance and reconnaissance (ISR) roles, it was reported that a significant portion of the UCLASS effort would be directed to produce a Super Hornet sized carrier-based aerial refuelling tanker as the Carrier-Based Aerial-Refuelling System, with “a little ISR” and some capabilities for communications relay, and strike capabilities put off to a future version of the aircraft.

In July thay year, the programme was officially named “MQ-25A Stingray”.

The Pentagon apparently made this change in order to address the US Navy’s expected fighter shortfall by directing funds to buy additional F/A-18E/F Super Hornets and accelerate purchases and development of the F-35C.

The introduction of this platform also addresses the carriers’ need for an organic refuelling aircraft, proposed as a mission for the UCLASS since 2014, freeing up the 20–30 percent of Super Hornets performing the mission in a more capable and cost effective manner than modifying the F-35, V-22 Osprey, and E-2D Hawkeye.

They are investing in getting UAV technology working from a carrier not just a “tanker”.

Good grief.

Lol. Aye it will be interesting to see what the cost would be if it went into pull production. Could it be produced for $50mm or less for 50 of them. There is a risk of specialising to much with uav’s of the airframe could be adapted to carry either fuel, pave-way or some sort of surface/airborne radar with high endurance it would be pretty invaluable

Yes a gloriously expensive idea @ $200 Mn a throw for the US Navy to refuel its F-35Cs and F-18s.

If you actually understood the program and this article, you would know that the USN is buying these UAV’s in order to preserve the remaining airframe hours on the F-18’s currently being used for tanking. And in so doing, delays the need to replace said F-18’s with new aircraft, which saves a shed load of money.

IOW, the program pays for itself through savings.

Why would they need modifying?

It means they nolonger need to modify F35b, V22 or E-2D to perform air to air refueling.

Ron5

There were zero plans to convert either the E-2D or F-35 to become tanker aircraft. Both aircraft are ridiculous candidates for that role. The V-22 is already qualified to perform air to air refueling for the Marines.

The current UN fleet of combat aircraft (all F-18 now) are all short on range, compared to previous generation of aircraft. The F35 is/will be similar to the F18. The old Tomcats and A6 intruder had much longer legs. The Navy boys need small, carrier borne refueling aircraft, to top them up after take off.

Also the CHinese now have a fleet of very long range surface to surface anti ship missiles, so the big carriers have to stay further out. They make a big target!

The F-35C has a much great range than the F-18.

Both the USMC and Royal Navy could do with something similar to extend the range of their F35B’s – they have a shorter range to accomdate the lift-fan. However they’d most probably need a VSTOL or rotor-based UAV for the purpose. If a general purpose rotar-based UAV then it could mean a Crowsnest module airborne 24×7 over the carrier.

Maybe the Airlander idea could meet this need in future. Giant airship with multi day endurance and the ability to land on water. Perhaps you wouldn’t use it as a tanker but as a crowsnest station etc it could work really well.

All they need to do is work out how to fly the thing when it’s windy…

csm
Guest
csm

I’ve had the same thought; give it the ability to be remotely controlled and refueled by helicopter and you’d have a 24/7 365 crowsnest with better ability for less cost.

As for windy conditions, think it needs wind data or a system to measure the wind loading to then feed into a fly by wire system. Also there should be less to crash into up there …

Airlander is great concept for long range logistics and with current ’50’ builds designed for up to 60tonne payload it has potential to fly 1000km from somewhere.. .loiter for a day and fly back. Not very discreet and no ability to get out of Dodge quickly if rumbled with cruise speed of only 105 knots however. Was thinking it could be a fantastic replenishment tool for containerised packages… CAMM? Or specialist mission modules for larger vessels that could accept an air drop… Hoist out old containers… Drop back in fresh containers…. Use self compensating lift technology utilised in offshore oil… Read more »

The only available option the RN have for aerial refuelling the F35Bs is via a buddy-buddy method. By using a F35 you take it away from its primary purpose as well as burning through airframe hours. The Merlin could possible be fitted out as a tanker, however it flies too slowly for the F35 to make it viable. The only proven method of aerial refuelling would be the V22 Osprey. The Chinook whilst being able to carry the fuel (7200Kg via ferry tanks) probably wouldn’t be suitable as it also couldn’t fly fast enough and the down-wash it generates may… Read more »

Chris
Guest

(Chris H) The air tanker contract has nothing to do with maritime refuelling although it does act as the main tanker resource for operations where required. As in F-35s off a QE attacking a ground position just as the UK A330s support US Navy F-18s off carriers in the Med attacking ISIS. If the Navy needed to sort Buddy up refuelling it could.

More false information David or ignorance? You are better than this and I am disappointed

Ron5
Guest

Few points: F-35 fuel capacity is well documented and can easily be found on the internet The only existing tanking capability that could be operated off the QE is the V-22 tanker. That program is more advanced than you think, the Marines are already planning on how to use it to extend their F-35Bs. None of your other suggestions are more than ideas. AFAIK none are funded for development. F-35B buddy tanking was for a while on the Marine’s wish list but was an early program cut. One option to extend F-35B range that I don’t think you mentioned, would… Read more »

Drop tanks would seem like a really good option to have available. Surely someone is going to develop them? Nice for a supplier from a business perspective too since they are, by their very nature, single use only (assuming a mission doesn’t get aborted). Are any of the F-35 external hardpoints designed to be wet? I think the Israelis were even talking about conformal tanks at one point although, given the differing forward fuselage shape of an F-35B vs F-35A due to the lift fan, I’m not sure how much transferability to the F-35B there would be of any Israeli… Read more »

Some useful information in relation to drop tanks. “In laymans terms, the F-35 has the piping in its wings, the pump systems, the connections, etc, but nobody has physically built tanks optimised for its aerodynamic qualities (external fuel tanks create a lot of drag; often quite a bit of the fuel they provide is cancelled out by the extra thrust required to fly with them), and nobody has run testing to make sure that such a fuel tank will jettison safely without impacting the wing or tail (this isn’t a major challenge, but it takes time to tune how the… Read more »

Julian
Guest

Thanks Nigel.

I suspect that due to the much more accurate computer simulations of aerodynamic properties developed in the last 20 years it is a lot cheaper to develop drop tanks (relatively speaking) and easier to maximise efficiency than it would have been for things like F-18. On the negative side though, any F-35 developments would presumably want to spend time and money to model and then measure the effect on RCS and reduce that as far as is practical.

Chris
Guest
Chris

(Chris H) Nigel – And of course while you can drop the tank you cannot drop the pylon on which it was mounted after tank drop. This will still add (as you say) drag and reduce fuel efficiency and more crucially reduce the ‘Stealth’ factor of the aircraft. One of my criticisms of the F-35 concept is that if ‘Stealth’ is its only saving grace then it can never carry wing pylons as Stealth’ goes right out the window. Or venturi. Or wherever…

The Israeli Air Force needs long-range aircraft that can carry a lot of fuel and weapons, because of Iran.

Cheers guys on a sensible debate. I never looked at the drop tank solution purely on trying to keep the aircraft with its standard RCS signature rather than loading up the wings. I would have thought that if the F35 was operating in the tanker role it would require drop tanks to augment the fuel required to be useful, so the capability would have been designed in. Didn’t know the USMC had dropped this requirement in favour of the V22, as I was led to believe this was an ongoing trial and therefor not a future plan. My repeating thought… Read more »

It would be very interesting to see (but unlikely to ever be seen because it’s probably classified) some fuel usage graphs for F-35B taking off from a QEC & entering level flight towards a target with various payloads. I’m thinking that the amount of work the lift fan is having to do to provide the lift augmentation on takeoff that a cat would otherwise provide (by the cat imparting extra airspeed over the wings) plus the aerodynamic drag from the lift fan flap being up during takeoff that presumably requires the main engine to be at full thrust for longer… Read more »

Chris
Guest
Chris

(Chris H) Julian – You make some interesting observations and I am sure you are right about the extra on-board energy needed for F-35B take off (even with a ramp). CATs will impart that energy but I think you will find an F-18 launched from a CAT isn’t fully fuelled if it has a full weapon load as there are limitations and why Buddy Up is so crucial. When the RN was the first to develop this for carrier use it was to support Supermarine Scimitar and de Havilland Sea Vixen and more crucially because the S1 Buccaneer was so… Read more »

The F-35B’s will use far less fuel when landing & taking off from the carriers than the F-35C mainly due to them not using afterburners for those evolutions. Afterburners use up a lot of gas as I am sure you know.

And in addition, the F-35B needs to retain far less fuel in reserve when landing. Arrested landing types need to retain enough fuel to enable bolters. The F-35B does not.

Chris
Guest

(Chris H) DaveyB – While it isn’t a current policy I have always thought that given the 3 Test & Evaluation aircraft at Edwards at some point will cease to be of value in that role, with advanced simulators now available making ‘trainer’ F-35s a waste of money and they will never be fitted out for combat use this leaves two options – Break up for parts or (as I believe) convert to tankers. The attraction of this is a) it makes further use of the large investment in these most expensive early aircraft and b) it is fundamentally simple.… Read more »

@DaveB It’s no secret that the Royal Navy would very much like to acquire some V-22 and that desire will only increase when the US marines bring theirs onboard. I would imagine that the new USN version (CMV-22B) would be the variant of choice given its extra long range. The RN could use it for long range night/day COD, search & rescue, SF insertion and, of course, tanking. The Marine’s V-22’s are qualified to tank but I don’t know that the CMV-22B will be qualified. Probably not. So adding that capability would cost some more testing. As you point out,… Read more »

By the way, the original idea for the Marines F-35B tanker was a reel and hose in one weapons bay. No extra fuel. I saw a drawing of it many moons ago. It might still be on the web somewhere.

I don’t remember any discussion about the proximity of the hose to the aircraft’s engine jet stream. I agree it would look to be awfully close and vulnerable. Maybe that was a factor in it being discarded. Long time ago now.

(Chris H) Ron5 – I haven’t seen that concept but you have triggered a Google search .. The other factor I was more concerned about was the ‘what if’ scenario where a central drogue could get stuck and was unable to be retrieved and then what happens when the ‘B’ comes in to land with its jet exhaust angled down right over that fuel pipe? I just think the idea is so very deliverable given what is already built into the airframe itself. The other thing that has intrigued me and maybe you know the answer is whether the larger… Read more »

The air intake on top is actually quite brilliant when you think about it. One of the most dangerous things on a crowded flight deck are the engine air intakes, and crew getting pulled into one. This is obviously even a bigger issue with unmanned platforms. The air intake on top makes that a non-issue i imagine.
