So apparently Boeing has won the contract...

I'm surprised it wasn't announced somewhere. ???

It's such a small acquisition, really. Just four airframes.

Which is why I doubt it will have a lot of impact on the T-X decision.

The program isn't for just 4 units. Where Boeing seems to have won the program that will mean more units down the road.

The program isn't for just 4 units. Where Boeing seems to have won the program that will mean more units down the road.

This award is for four aircraft with no guarantee it transitions to production.

Even if they actually buy it out fully, it's less than 80 airframes.

Sure, but the same could be said of any program at this phase. The point is they're aren't going to have Boeing build four units and go, "whoa, did we say 'Boeing'? We meant General Atomics."

Well, the US Navy did that after a two unit build mind you.

"The Unmanned Combat Air System – Demonstrator (UCAS—D), is a six-year project that calls for proving carrier operations with the X-47B starting in 2011. The USN currently plans to make a decision after 2013 on a potential follow-on acquisition programme for a long-range strike fleet."

From the contract:

"The Boeing Co., St. Louis, Missouri, is awarded a ceiling price $805,318,853 fixed-price-incentive-firm-target contract to provide the design, development, fabrication, test, verification, certification, delivery, and support of four MQ-25A unmanned air vehicles, including integration into the carrier air wing to provide an initial operational capability to the Navy."

That was never part of the X-47B work AFAIK.

Correct. Specifically to your comment though, the US Navy has not yet shown a follow-on production program in their future carrier airwing documents or budgets.

One would hope this is the end of the six year cycles, but so far:

The Navy held a competition and paid a contractor for six years to build two operationally relevant vehicles to demonstrate CVN compatibility and USN aerial refueling receiving with a follow on decision for an acquisition program.
The Navy now held another competition (after much debate) and is paying a another contractor for six years to build four vehicles to certify CVN compatibility and USN aerial refueling giving to a four vehicle IOC state with an apparent follow on decision and funds for a production program.

Fair enough. It does seem more solid than UCLASS/X-47B/whatever was.

Well it's not an X anymore but has a proper designation :

fixed-price-incentive-firm-target contract to provide [...] four MQ-25A unmanned air vehicles

[aero-engineer]

Fair enough. It does seem more solid than UCLASS/X-47B/whatever was.

UCAS-D (D for "demonstration" program) was X-47B flight test and ran from Aug 2007-2014 and the 2015 aerial refueling was added. First flight was in Feb 2011. UCAS-D evolved from the J-UCAS program of the early 2000s.

UCLASS was development program to develop a future UAS system. The RFI was spring 2010, requirements were formulated, PDR contracts fall 2013 to spring 2014 to four contractors, but the final RFP was never let and portions of UCLASS were rolled into the new CBARS/MQ-25 program in 2016.

UCAS-D and UCLASS were two separate activities occurring at the same time (but in different phases) managed by the same program office.

 

[Hanse]

I stopped trying to keep the whole mess straight years ago. In the end tossing away the X-47B seemed like a tremendous waste.

 

[marauder2048]

Unlike UCAS-D/UCLASS you're required to have an LRIP quantities/strategy at this milestone for MQ-25.

But, AFAIK, there's been nothing but silence on that point.

LRS-B, a program at a much higher level of classification, had its LRIP quantities/strategy announced *before* the contract was awarded.

[fredymac]

Only 2 key performance parameters: carrier ops capable and fuel delivery at range. No tie in for strike/recon application other than the control software that provides the carrier capable operations which will be made open to government transfer for other uses. Does sound like this is a program intended for series production and application to the entire carrier fleet.

[TomS]

Much better sense of scale from these images. That is not a small aircraft. Could be the largest on a carrier since the A3D.

 

[LowObservable]

Long wingspan, but less power than any non-trainer carrier jet since the A-4.

https://www.flightglobal.com/news/articles/phantom-works-selects-rolls-royce-turbofan-to-power-447360/

Don't forget this was designed as an ISR platform, not a tanker.

 

[TomcatViP]

P/W ratio is here less sensitive:

- modern construction techniques make the airframe lighter
- very restricted KPP turn the plane into a flying gas tank only;Tanks that could be emptied quickly in case of an aborted mission to land back with a comfortable P/W ratio.
- Superior trim and pitch and yaw controls makes any landing easier and less reliant on power (when compared to a flying wing)


It is obvious however that if the plane is turned into something that need to carry and trap back with an heavy load of weapons, then the low engine power ratio might be a source of concerns. But still, this is not the case today for any projections that can be made realistically.

Boeing marks first big defense win in more than a decade with MQ-25A

After losing several big defence contracts over the past decade – resulting in consistently falling revenues – Boeing Defense, Space & Security (BDS) has finally notched a big win.

Ultimately, it is not clear if the USN will fully embrace the MQ-25 concept and order a full complement of 72 aircraft, given its conservative reputation and the meandering legacy of the programme, which started in 2010 as the Unmanned Carrier-Launched Airborne Surveillance and Strike programme before evolving into an aerial refuelling mission.

“The navy has changed the concept multiple times, changed the focus of the program, and so there is a lot of scepticism about ultimately how much commitment there is and how many systems they will buy,” says Finnegan, noting, nonetheless: “It’s clearly important [to Boeing] even if the navy doesn’t buy a large number of systems.”

https://www.flightglobal.com/news/articles/boeing-marks-first-big-defense-win-in-more-than-a-de-451695/

 

[totoro]

What do they mean first Boeing win in more than a decade? What about KC-46 in 2011? Total worth of that was 43 billion, for development and procurement. That's a pretty big win, several times bigger than MQ-25 could be worth, IF all 72 planes are bought in the end. Not to mention Boeing is pretty well set to win further tanker contracts. And in even farther future, it's best positioned to design, make and win any future transport plane contracts.

That being said, I really do hope Boeing wins the T-X as well. Then LM can bag USAF's 6th gen plane and everyone is happy.

If you think about it, a strike and tanking mission are similar. Fly out,offload the payload, and fly back.

Therefore, it is reasonable to presume if UCLASS had "some light strike capability" it probably only had "some light tanking capability".

As a side note, Boeing has just opened the market for Stealthy autonomous tankers.

Btw, as already mentioned some time ago:

X-47B, 1x Pratt & Whitney F100-220U: 16000 lbf (71,17 kN)
MQ-25, 1x Pratt & Whitney PW815GA: 15680 lbf (69,75 kN)

 

[VTOLicious]

The 15000 lb might be doable if the capacity of the Buddy Store + another fuel tank is considered:

Internal capacity "give": 1440 gal (5451 l) (corresponds to 3x 480 gal tanks )
External capacity "give": 1x Buddy Store 300 gal (1136 l) + 1x FuelTank 480 gal (1817 l) = 780 gal (2953 l)

Total fuel "give": 2220gal (8404 l), JP5 @ 0.81 kg/l = 6807kg (15007 lb)

EDIT: In case of the X-47B, 15000lb is exactly half of its useful load:

Empty weight: 14,000 lb (6,350 kg)
Max. takeoff weight: 44,567 lb (20,215 kg)

Useful Load: 30567 lb (13865 kg)

...any thoughts?

Boeing is using an AE3007N, which claims "more than 10K" of thrust.

The A2 is over 9,400lb so it's not impossible. (Thought it should be noted that is takeoff only. Continuous is about 8k.)

[Mike OTDP]

I'll be honest, this pick surprised me for several reasons.

The first was that I expected it to come after T-X. Boeing needs something to keep the St. Louis facility open after Super Hornet production winds down, which meant either T-X or MQ-25. T-X was scheduled to be awarded in July of this year, my thinking was that this would be delayed (which has been routine for over 30 years) three months or so...and if Boeing won, the Navy had a free hand with MQ-25.

As for the choice, I had figured that with Lockheed building F-35s for the next 20 years, they weren't going to get the contract. My own bet was on General Atomics, mostly due to the greater level of UAV experience and the more powerful engine.

One thing to remember is that the whole UAV-as-bomb-dropper was something industry was trying to fob off on the Navy. From the Navy's perspective, they had F/A-18s that dropped bombs, F-35s that dropped more bombs, and Tomahawks that were self-dropping bombs. There's no need for another bomb-dropper...but a crying need for a tanker that is significantly cheaper than a Super Hornet. No, the Navy played this right.

Given all of that, the only company I can think of that might have more carrier suitability experience is NG with all of Grumman's experience. But Mac wasn't a slouch in that regard either. Also, they already have a prototype ready to fly. A couple of things Forbes doesn't know is all of the work that has already been completed by Boeing and experience they may already have with regard to many of the systems on the MQ-25 through classified programs.

Then you're suggesting that the acquisition chief who was deeply involved in UCLASS/CBARS/MQ-25
and whose deputy during that effort has been and is now the program manager for the MQ-25 isn't familiar with the
materially relevant background of one of NAVAIR's main contractors despite visibility into their preliminary
UCLASS design on which their current prototype is based.

 

[TomcatViP]

I wasn't myself very convinced with that piece of Forbes. Although the author did display a good insight of the program undoubtedly, he has IMO bypassed the fact that the two main KPP are fairly reasonable. We are supposed also to understand that the MQ-25 from Boeing already has an extensive flight history and that systems related modifications [expect perhaps CATOBAR] are fairly well understood already.
Boeing certainly can take up the challenge cost-wise.
The KC-46 was way more challenging (build a tanker after years of lost experience / modify a standardized civilian product at very low cost (initially) / create an entire new modernized set of system for refueling aircraft - all that while facing an aggressive (and proved to be surrealistic) bidding from a massive competitor) .

 

[TomS]

Please

We are supposed also to understand that the MQ-25 from Boeing already has an extensive flight history and that systems related modifications [expect perhaps CATOBAR] are fairly well understood already.

We are? My understanding is that Boeing's MQ-25 prototype has never flown and that the actual production representation aircraft may be significantly different from the prototype (new wing at least).

 

[TomcatViP]

Yes. But initial info were that it was derived from a program requesting a flying stealthy UAV (and that it did fly).

 

[bring_it_on]

It was amusing that Boeing didn't sprinkle some *Black Diamond* fairy dust (at least publicly) this time around.
