F-35 chief expects P&W's bomber work to reduce F135 cost
10 Mar 2016 James Drew

"The head of the multinational F-35 Joint Strike Fighter programme expects Pratt & Whitney to significantly reduce the cost of the F135 now that it has been named as the propulsion system supplier for the Northrop Grumman B-21 bomber.

Lt Gen Christopher Bogdan would not confirm if the F135 engine core is common with the B-21 powerplant but says there are enough “benefits” to warrant price reductions for the F-35 programme.

The F-35 joint programme office (JPO) has already reached a “handshake” agreement for 167 of the high-thrust military turbofan engines under low-rate production lots nine and 10, but price reductions might come with production of 100 B-21 bombers ramps up in the 2020s. The air force has not said if the stealthy B-21 is powered by two or four engines.

“I think some things we learnt on the F-35 engine with Pratt & Whitney will greatly benefit the long-range strike airplane, and at the same time, I think Pratt & Whitney ought to be looking to drive the cost of the F-35 engine down now that they have that extra business,” Bogdan said at a defence programmes forum in Washington DC on 10 March. “We expect them to.”...

...A spokesman for the engine manufacturer declined to comment on the B-21 or Bogdan’s comments, referring all question[s] to the air force. F135 assembly is scaling up as the F-35 fighter acquisition gathers pace, with output jumping 110% between lets[sic] [LOTS/LRIP] eight and 10."

I don't know if the contractors line up, but the B-21 really could stand to steal almost all of its guts from the F-35: DAS, IRST, radar (maybe two, like the B-2), antennas, countermeasures, engines, sensor fusion engine, weapon control system, etc.

Oh dear. Don`t tell Maus. :mrgreen: The B-21 was suppose to hurt the JSF but the B-21 might in turn out to burn every bridge that the detractors hope for & pray for in a death spiral. Especially if count_to_10`s points are achieved. To take this further, the F/A-XX might well adopt many of these systems helping to push out the JSF from 2020 to 203 & beyond :devil:

B-21 And F-35 Engines May Share Tech; Pratt Won’t Talk
10 Mar 2016 Colin Clark

"[Gen. Bogdan said:] ...“There are some things we learned from the F135 engine that will greatly benefit the Long Range Strike airplane. At the same time, I think Pratt and Whitney ought to be looking to drive the cost of the F135 engine down and I would be expecting them to.”

Pratt and Whitney spokesman Matthew Bates politely refused to be drawn as reporters prodded and teased him. Later, he provided this statement.

“We do not plan to say one word more or one word less than what the Air Force has already said about the program. Pratt & Whitney is the engine provider for the B-21 bomber.”


The Air Force said nothing.

When reporters pressed Bogdan after his presentation, he said cost savings could be achieved if an engine shared common elements, but he wouldn’t go further than his original reply to the Air Force Association’s veteran reporter John Tirpak, whose question prompted the general’s first comment on the Long Range Strike Bomber (or the B-21 or B-3!).

The most logical conclusion is that the cores of the two engines — the heart of a high performance jet powerplant like the F135 — may have common design elements...." [JUMP at the URL for MORE]

Yep, I would say Northrop Grumman would be in pretty good position just based off of what they themselves provide...
Northrop Grumman plays a critical role in the development, demonstration and production of this multirole fighter [F-35], including:

The production of the center fuselage, which forms a significant portion of the aircraft's internal weapons bay and internal fuel capacity
The design and production of the AN/APG-81 Active Electronically Scanned Array (AESA) fire control radar, which brings unmatched capability to air-to-air and air-to-surface missions, complemented by significant electronic warfare and intelligence, surveillance and reconnaissance functions
The design and production of the AN/AAQ-37 Distributed Aperture System (DAS), which provides simultaneous modes of situational awareness, infrared search and track, missile warning and navigation not available on any other aircraft
The design and production of the AN/ASQ-242 Communications, Navigation and Identification (CNI) avionics suite, which can be dynamically programmed to arm the F-35 pilot with multiple-mission capabilities engineered for seamless transition from one mission phase to the next
The development of mission systems and mission-planning software
The development of pilot and maintenance training system courseware
The management of the team's use, support and maintenance of low-observable technologies

:devil: Wow - BS will get a shock exposed to all that F-35 NG information. :doh: Perhaps he will be blindfolded at all times? :mrgreen:
