But on the others I only found some text information:
---------------------------------------------Proposals for the LXF
Five manufacturers submitted proposals in response to the RFP --- Boeing, Northrop, General Dynamics, Ling-Temco-Vought, and Lockheed. In March of 1972, the Air Staff concluded that the competing Boeing Model 908-909 was the first choice, with the General Dynamics Model 401 and the Northrop Model P-600 being rated as close seconds. The Vought V-1100 and Lockheed CL-1200 Lancer had been eliminated.
The Source Selection Authority, after further work, rated the General Dynamics and Northrop proposals ahead of the Boeing submission. The General Dynamics Model 401-16B and the Northrop P-600 were chosen for further development on April 13, 1972, and contracts for two YF-16s (72-1567/1568) and two YF-17s were awarded. Rather than the "X" (experimental) prefix being used, the "Y" (development) prefix was used in order to indicate that a mixture of off-the-shelf and experimental technologies were being used. The YF-16 was to be powered by a single Pratt & Whitney F100 turbofan, whereas the YF-17 was to be powered by a pair of General Electric YJ101 engines.
The "cost plus fixed fee" contracts covered the design, construction, and testing of two prototypes, plus a year of flight testing. At the time, the Air Force was still very much committed to the F-15 fighter, and visualized the LWF program as more of a technology-demonstration project rather than a serious effort for a production aircraft. At the same time, contracts were given to Pratt & Whitney for a version of the F100 turbofan specially adapted for single-engined aircraft and to General Electric for the new and smaller YJ101 engine. http://www.f-16.net/reference/versions/f16_lwf.html
.... but yesterday ... THANKS Habu2 from f16-net B) here it is:
Vought's LWF proposal, from Jay Miller's book:
AeroFax AeroGraph No.1 von Jay Miller (ISBN 0-942548-01-9)
... there’s not only a picture of a model of Boeing’s model 908 and a report an Vought’s V-1100 and V-1600/1601 the proposed Navy-Version (single and twin seat versions) !!!
"Aerofax AeroGraph no.1 by Jay Miller has drawings of Vought's LWF proposal, the V-1100 (p.16) and a photo of a model of Boeing's LWF proposal, the Model 908 (p.19). The V-1100 looks like an F-8 Crusader with a longer nose and the intake lip moved back. Boeing's 908 looks amazingly like an F-16, with a bubble canopy, strakes along the fwd fuselage, a similar wing and tail planform. The main difference is the 908 has a more round rear fuselage instead of the extended 'side pods' of the F-16.
This book also has a chapter on the Vought V-1600, the Navy version of the LWF. If the contract had been let, Vought would have built the naval version of the F-16. Imagine an F-16 with strengthened landing gear, twin nose wheels, catapult bar, arresting hook, refueling probe and built-in boarding ladder. The two-seat V-1601 had a raised rear cockpit, with the back-seater's knees at the same elevation as the front-seater's head. The V-1601 front canopy hinged at the front and the rear canopy hinged at the rear. The navalized F-16 was forced upon the Navyand they fought the program until they finally killed it."
... after the lost LWF-contest it was decided that Vought would do the development work for the corresponding Navy contest ... as McDD was choosen for the YF-17 development into the F/A-18 .... the resulkting desing was model V-1600 and 1601 a navelised F-16 :
