Two YF prototypes were built. The YF was stealthier and faster, but less agile than its competitor. After a four-year development and evaluation process, the YF was announced the winner in and the design was developed into the Lockheed Martin F Raptor , which first flew in and entered service in The U. Navy considered using the production version of the ATF as the basis for a replacement to the F , but these plans were later canceled. The two YF prototypes are currently museum exhibits. American reconnaissance satellites first spotted the advanced Soviet Su and MiG fighter prototypes in , which caused concern in the U. Both Soviet models were expected to reduce the maneuverability advantage of contemporary US fighter aircraft. The RFP was modified in May to include the evaluation of prototype air vehicles from the two finalists. Northrop and McDonnell Douglas formed a team with a similar agreement. Both teams were given 50 months to build and flight-test their prototypes, and they were successful, producing the Lockheed YF and the Northrop YF In , the USAF changed the runway length requirement to 3, feet m , so thrust reversers were no longer needed. This allowed the aircraft to have smaller engine nacelle housings. The nacelles were not downsized on the prototypes. The second prototype was painted in two shades of gray and nicknamed "Spider".

The fuselage and empennage trailing edge pattern would also have fewer northrop yf 23 and the engine thrust lines were toed in at 1. Pitch was mainly provided by rotating these V-tail fins in opposite directions so their front edges moved together or apart. Paul, Minnesota: Motorbooks International Publishing,

Called Augmented Turbofans, these new engines would have allowed both the YF and the YF to fly supersonic without using the afterburner, resulting in fuel savings and increased combat radius and effectiveness. The YF emphasized stealth characteristics: in fact to lessen weight and increase stealth, Northrop decided against using thrust vectoring for aerodynamic control as was used on the Lockheed YFA. By comparison, the YF achieved Mach 1. The YF was tested to a top speed of Mach 1.

In what may be my favorite installment in our ongoing series on Northrop's YF Black Widow, we hear directly from famed test pilot Paul Metz. Metz started his career as an FG Wild Weasel pilot in Vietnam and went on to become one of America's preeminent test pilots. In the video below, he describes what the ATF program was like from the inside and just how good the YF actually was. In addition, we get extra color on the accelerated flight test program Northrop executed for the competition from test pilot Jim Sandburg. Their testimony combined gives us an unprecedented look into the YF program and paints a clear picture that YF was indeed equal if not superior to its competition. This gem of historical reference has been largely overlooked even as the YF has risen to near legendary status, becoming one of the most enigmatic and fascinating modern aircraft in history.
