VFAX/NACF Projects (Pre F/A-18 concepts)
« on: January 11, 2007, 01:50:10 pm »
Came across the following in Air International.

Seven companies responded to the VFAX RFP for unfunded proposals for a Mach 1.6 aircraft with 28,000-30000lb weight an unit cost less that $6 million in 1975 dollars over a 400 aircraft program.

General Dynamics submitted two designs; a stretched YF-16 called Model 18 from Fort Worth and the Model 218 from Convair, based on the Model 200 VSTOL fighter.

Rockwell submitted a proposal that was largely a conventional derivative of the XFV-12.

Northrop proposed the P.630, a larger derivative of the YF-17.

McDonnell-Douglas submitted a canard equipped design with a family resemblance to the F-15.

Grumman & LTV also submitted responses (no details).

Sorry, if I overlooked this in another thread, but I have no designation to search for ...

"This is the design that McDonnell Douglas was offering at the time of the VFAX hearings prior to the requirement to navalize the Air Combat Fighter."

A very big coincidence - thanks Boxkite for posting this, its clearly marked as Navy where the other "McDD VFAX" drawing isn't, and there are minor differences like engine inlets

The VFAX program was cancelled and replaced by NACF (Navalised Air Combat Fighter) which was based around navalising YF-16/YF-17.

I borrowed the book only for a short time - enough to scan the most important pics, but nothing more. So I don't have access to the contents of the publication (ISBN of the UK edition 1557507759) now  :( . Sorry.

Wow, that's the first time I've seen the McDD design. That looks very cool, in the sense that it kind of reminds me of an F-4 crossed with an F-16 with canards, which, didn't an F-4 get flight tested with canards, if my memory serves me correctly? Hopefully, someone has data on the other designs.

Yes, it did. It was experimental plane F-4CCV. Some pics are for example in "Aviation Record Breakers" from Quintet Publishing Ltd., London, 1995

Bizarre aviation expert.

Did this design get assigned a model number by McDD?

I expect so, but I don't know it yet. The F/A-18 was Model 267, we know the 265 design, logically it would be in the 200s somewhere before 265.

I seem to remember reading that the McDD VFAX design had the "glass cockpit" concept used on the FA-18.

Found it!

It was Model 263,

packed with well thought out engineering features, not least being a superb one-man cockpit, four channel digital flight controls and the capability of flying both fighter and attack missions.

Found VFAX in Airscene, Air Enthusiast January 1974

Quote
The US Navy is considering launching a development program for an advanced shipboard light strike fighter in the 25,000-35,000lb weight category as a successor to the Vought F-8 Crusader and Vought A-7 Corsair. Intended to possess both strike and air defence capability, the fighter is intended to have a unit cost of $5-6 million and if the US Navy decides to proceed with the programme a proposal request for 90 day definition studies will be issued to selected contractors later this year with a single contractor being chosen by January 1975 to build eight prototypes. A number of companies are conducting preliminary studies including Boeing, Vought, McDonnell-Douglas, Lockheed and Grumman. Northrop is proposing a heavier, two seat version of the YF-17, the P630, and General Dynamics is proposing a stretched version of the YF-16.
