The same day F-15EX first flew, QA 006 flew and QA 008 flew for the first time and without CFTs, only the second time a QA has flown without them. Was supposed to go do M2.3 - on a first flight! The departures were special - gear up, hold it low to the end of the runway then pitch up into a Viking departure right on top of us (had my 16 year old son with me - he was enthralled!). That's when you feel noise!

Enjoy the Day! Mark

In that last citation there is a reference for a Westinghouse PESA for the F-15. I’m not familiar enough with the F-15 to know if they ever used block numbers or if the author meant F-16. The document is from 1994 so I assume apg-63(v)2 had at least begun development.

Its a typo.

There is no Block 50 F-15 but there is a block 50 F-16.
 
I'm curious, was there ever a study done on how much it would cost to turn the stol f-15 into a production aircraft.
 
In "Tailless Vectored Fighters: Theory, Laboratory, and Flight Tests" (ADA317838 , https://apps.dtic.mil/sti/pdfs/ADA317838.pdf) there is a tailless F-15 wind tunnel model depicted that is (probably) an extension of some earlier efforts towards a reduced signature F-15 configuration.

Do we have any idea of what the number of fighters requirement were for the f-15 before the f-16 came onto the scene?
 

F-15 Global Strike Eagle​



In 2006, Boeing proposed a similar concept for missile launch, this time using an unmanned variant of the F-15E Strike Eagle with the launch vehicle mounted dorsally instead of ventrally. Boeing designated this variant as the F-15 Global Strike Eagle (GSE). The concept proposed the F-15 GSE as a low-cost demonstration of global strike capability utilizing a variety of munitions including the little-known Common Aero Vehicle (CAV). Defined as a maneuverable, hypersonic reentry vehicle that has the capability of dispensing a variety of payloads inside the atmosphere, the CAV concept eventually merged with the Air Force/DARPA Falcon project. Providing a Low Earth Orbit (LEO) launch capability for micro satellites, or microsats, was another mission possibility for the F-15 GSE and, with future upgrades, delivering heavier ballistic and orbital payloads.

That's an intreging question Cjc!!
I look forward to the answer.

Early F-X studies were made on a 1000 fighters figure (as in 1963 and 1968).
First detailed chart I've found is from 1969 (3rd picture) at 749 airframe.

Single seater with wingtip missile launchers and an extended wing span?

What is the vintage of this proposal? Any details?

1990. Extended wing, supercruise, ATF engines and avionics.

Edit: Composite wing, span 48ft 5in for area of 670 sq ft. Swept at 38.5 deg, leading edge slats introduced. Fuel capacity increased by 3,000lb to 16,257lb. Some front-quadrant RCS reduction.

The Senate reportedly added $100 million of long-lead funding for the F-15 program to the 1991 USAF budget "to protect the option of the F-15XX", according to Flight ( and AvWeek ) from July 1990. Seems an enormous amount of money.

This looks like a tailless F-15 being tested at the radar range mentioned here:

 
And no canard neither. It must be a very early rendering.
The painting was later updated with the nozzles and foreplanes, as in this vintage brochure, randomly seen on Evil-bay.
