Passive multistatic radar , bistatic radar  and especially multistatic radar systems detect some stealth aircraft better than conventional monostatic radars , since first-generation stealth technology such as the F reflects energy away from the transmitter’s line of sight , effectively increasing the radar cross section RCS in other directions, which the passive radars monitor. Archived from the original on 28 February Stealth attack aircraft . The FA’s faceted shape made from 2-dimensional flat surfaces resulted from the limitations of the s-era computer technology used to calculate its radar cross-section.

Much of that increase was allocated towards the production of an operational stealth aircraft, the Lockheed FA, under the program code name ” Senior Trend “. Back Bay Books, United States Department of Defense12 May This same radio call had been used by the enigmatic th Test and Evaluation Squadronalso known as the “Red Hats” or “Red Eagles”, that often had flown expatriated MiG jet fighters in the area, but there was no relationship to the call and the formal F designation then being considered by the Air Force.

Apparently, use of the “” radio call became commonplace and when Lockheed released its first flight manual i. 1f117 forget to sign up.
The designation “F” seems to indicate that it was given an official designation prior to the U. According to Combat Aircrafta single F was blasting through the area at low-level while a pair of Fs were following in trail from above.
Fs took part in the conflict in Yugoslaviawhere one was shot down by a aaircraft missile SAM in ; it was the only Nighthawk to be lost in combat. Fast forward seven months and we are blessed with absolutely the best photo of an F in flight since the type’s retirement 11 years ago.
The operational aircraft was officially designated “FA”.
A History of Fighter Pilots. The F is primarily wircraft attack aircraft,  so its “F” designation is inconsistent with the DoD system. The United States Navy tested the F in but determined it was not suitable for carrier use.
Congress’s former mandate to keep the fleet of roughly 52 jets in F117 regenerative storage indefinitely at the high-security Tonopah Test Range Airport has ended. After the explosion, the aircraft became uncontrollable, forcing the pilot to eject.
By Aprillawmakers appeared ready to “remove the requirement that certain F aircraft be maintained in a condition that would allow recall of those aircraft to future service”, which would move them from storage to the aerospace maintenance and regeneration yard in Arizona to be scavenged for hard-to-find parts, or completely alrcraft.

The F’s story has been something of an obsession of mine over the years. The F has been used several times in war. The first production Aricraft was delivered inand operational capability was achieved in October United States Air Force. You better soak this image up why you still can, though! Retrieved 18 July The image comes to us from our good friends over at my favorite magazine on aidcraft planet, Combat Aircraft. By the s, when Lockheed analyst Denys Overholser found Ufimtsev’s paper, computers and software had advanced significantly, and the stage was set for the development of a stealthy airplane.
So to say the least, it is a personal joy to see a stunning photo like this snapped in the year The Nighthawk was the first operational aircraft to be designed around stealth technology. Wikimedia Commons has media related to F Nighthawk.
