Definitely. That was an excellent article. It really got rid of a lot of speculation.

The LockMart design went from canard to quad-tail shortly before the CDA RFP deadline (which was in 1996). The main reason was that the carrier version was going to need a larger wing than the span-restricted (LH-class parking) CV/STOVL aircraft, and larger control surfaces. Scaling up a delta wing, while keeping its sweep angles constant (LO constraint) is difficult configuration-wise because the increase in root chord - in feet and inches - gets very large... so where do you put the (also larger) canard? A wing with less sweep and taper, and an aft tail likewise, made it easier to accommodate two wing designs on the same body shape.
The LSPM (large scale powered model) in the Google Earth photos was built as a canard, but I suspect that they modded it to get some idea of the difference in suck-down effects.
I have a suspicion he worked on the ill-fated XFV-12 thrust augmented fighter. Which was an utter failure. This probably helped when he "invented" the F-35 lift fan 15 years later.he was Manager of Advanced Programs at Rockwell International’s Navy aircraft plant, where he led the design of VSTOL interceptor
Given that he got the patent for it, why would you imply he didn't?Archibald said:This probably helped when he "invented" the F-35 lift fan 15 years later.
It primarily was supposed to be a cost reduction measure if I'm not mistaken, with a bit of engineering simplification as a secondary objective I think. The old 'pennywise, pound foolish approach' in other words.What I find interesting is the single vertical tail utilized for a period of time which to the best of my knowledge is a cardinal sin if you are hoping to achieve a VLO radar signature.
Is there any more detailed information on the development of the design between Configuration 141B (which included the three-bearing swivel nozzle) and the final configuration selected for the X-35 prototypes?

On July 20, 2001, Lockheed Martin, U.S. military officials and the aerospace community focused their attention on a single X-35, the concept demonstrator aircraft that would later be known as the F-35, stationed in Edwards Air Force Base, California, as it embarked on a journey to pass one of the most significant flight tests in aviation history – Mission X.
