Similar to the above but canard delta. Identified as "Advanced Design Composite Aircraft", with 80% composite structure, weighing 25% less, costing 20% less and saving 30% on fuel over a conventional fighter, from Grumman advert in Flight International 2 Sept 1978.

Those "TsAGI Technical Briefing on ATF Program" drawings suck. Here are better ones.

And so the endless circle of life comes to an end, meaningless and grim. Why did they live, and why did they die? No reason. Two hundred million years of evolution snuffed out, for in the end Nature is horrific and teaches us nothing

Thanks for those drawings, Scott. Top stuff.

The TsAGI technical bulletins I downloaded from the internet are pretty low quality, but they do nicely sum up everything that was in the open source press about US programs, including references to the source articles. For example, in here:

http://www.secretprojects.co.uk/forum/index.php?topic=111.0

I've posted the references for the ATF article, which could be useful for tracking down the original source materials.

Paul.

ISTR these were the order the companies were ranked when they narrowed it from 7 to 4

Lockheed
Northrop
General Dynamics
Boeing
McDonnell Douglas (apparently they raided Lockheed for stealth expertise)
Rockwell International & Grumman brought up the rear but I don't know the order.  As one person in the decision chain put it "We had a couple very good proposals, a few pretty good ones and the rest just didn't seem to get it."

Anyway here's a couple Grumman (probably been here before but this seems to be a good place for them so all the companies are covered)

"DARPA Hard"  It ain't what it use to be.
