401, later the YF-16 (now Lockheed F-16). Among the Boeing Model 908-909 features include a frameless bubble canopy for better visibility and a Pratt & Whitney F100 turbofan engine. Wind tunnel tests were conducted at the Langley Research Center as Test 281. The Lightweight Fighter proposals were delivered to the Air Force by the February 18, 1972 deadline. The Boeing Model 908-909 was the winner of a preliminary analysis. Other submitted designs included the General Dynamics Model 401 and Northrop Model P-600 which were deemed second and third place, respectively. The General Dynamics Model 401 was renamed the YF-16 and was the eventual winner. The P-600 was renamed the YF-17, later F/A-18 was a further modification. The Vought Model V-1100 and Lockheed Model CL-1200 were fourth and fifth place in the preliminary analysis.
