And another one ... The nameplate lists Lockheed–Martin, Northrop–Grumman and BAe. No McDonnell Douglas.

Neither – this is 1/48 scale, as marked.

My favorite JSF design. My future USAF would have been these and F-23s :'(

Looks stunningly like single engine China J-20, or like single engine version of some 6th Gen drawings floating around. (reposted from previous post). Why couldn't the F-35 look like that.

Has it ever been established which elements of the final design BAe brought to the party?

Impact of agility requirements on configuration synthesis
Author(s): Oneil, Patrick J.; Nyberg, Gregory; Deturk, Robin; Seal, Daniel W.; Grethlein, Christian E.
Abstract: A configuration design study was performed by McDonnell Douglas Aerospace (MDA) for the NASA Langley Research Center to determine the impact of agility-based requirements on the design of multirole aircraft. Design guidelines and methodologies were developed which can guide the aircraft designer in the selection of aerodynamics, controls, avionics, propulsion, and materials technologies for a given level of both agility and observables requirements. A matrix of nine aircraft was generated to investigate the quantitative effects of agility-based requirements and observables requirements on vehicle design and sizing. This matrix of aircraft indicates the relatively large TOGW penalty associated with high levels of agility when applied to a vehicle with significant observables requirements. However, the matrix also suggests that optimal integration of certain advanced technologies, such as in tailless fighter design synthesis, might have significant advantages over designs incorporating more conventional technologies. Finally, the study identifies the types of technologies required to achieve high agility under different observables requirements and allows some assessment of the current risks associated with these technologies and how future research might be focused toward reducing such risks.

Does anybody know where to find a pdf copy of the document? The link is no longer active, and the NASA report server does not provide a pdf version.
Thanks a lot in advance.

Calf... such an appropriate, prescient name for the F-35, really. In french "un veau" is a much maligned aircraft, for whatever reason the hatred...

random but I just noticed that Boeing's Loyal Wingman looks a lot like the McD's JAST, just unmanned.
wouldn't be surprised if some of the engineers from McDs are still in Boeing after the merger

I definitely agree with that, the MDD/NG JSF offering had V-tails more flattened out, same Lambda wing planform, put a canopy on it, pretty close. The MDD/NG JSF could have given the X-35 a run for its money. The Marines did not want to support a second engine type though.

This design is used in NASA/McDonnell-Douglas studies of offtake jetpipes, e.g. NASA Technical Memorandum 106387. Probably not a real "project" but interesting nonetheless.

That 180 turn does ugly things to the thrust delivered, and the pipes take up valuable internal volume...

I've always thought that composites are bad for stealth, as it is transparent to radar, and therefore, exposing the internal structure to radar.

Depends on the composite.

• Fiberglass will expose the internal structure (there's a story about replacing the aluminum skin of some plane with fiberglass for RCS testing and the RCS was much bigger with fiberglass skins). But that also means that a fiberglass on foam construction will have next to no RCS, and you can use a very small amount of RAM around the metal parts alone, wrapped inside the fiberglass for protection.
• Carbon fiber reflects radar like metal does.

My imaginary USAF was filled with these and F-23s. What a great looking airplane.

 

[Hydroman]

This could have potentially beat the X-35 but the separate lift-plus-engine was the killer. The MDD gas driven lift fan would have also had performance issues as well. This would have been a excellent USAF and USN version though.

I really think that the JSF should have stuck to a two-service airframe, with the Marines getting a unique design that may not even share parts with the JSF.

Because seriously, what mission requires vertical takeoff and supersonic flight, and how often does that mission come up?

Since fantasy is mentioned, how bout including Lockheed swing wing LRS-B for theater bomber role replacing the F-15E and B-1B. Navy gets ASF-14 with additional frontal RCS reduction for fleet defense and quarter back/bomb truck behind supporting A/F-X. Marines get the Lockheed canard ASTOVL.

Especially now that Marines basically playing Sea Rangers. A smaller STOVL UCAV would fit the role better. I just don't buy the island hopping f-35B they touting. No one wants to see an intact f-35B in Chinese parade.
