A Semi-Scale ARF R/C Model of the USA's First Specifically-Designed Night Fighter
History of the P-61 Black Widow
The heavily-armed Black Widow was the USA's first
aircraft specifically designed as a night-fighter. In the
nose, it carried radar equipment which enabled its crew
of two or three to locate enemy aircraft in total darkness
and fly into proper position to attack.
The XP-61 was flight-tested in 1942 and delivery of
production aircraft began in late 1943. The P-61 flew
its first operational intercept mission as a night fighter
in Europe on July 3, 1944, and later was also used as
a night intruder over enemy territory. In the Pacific, a
Black Widow claimed its first "kill" on the night of July 6,
1944. As P-61s became available, they replaced interim
Douglas P-70s in all USAAF night fighter squadrons.
During WW II, Northrop built approximately 700 P-61s;
41 of these were -C variants manufactured in the summer
of 1945 offering greater speed and capable of operating
at higher altitude. Northrop fabricated 36 more Black
Widows in 1946 as F-15A unarmed photo-reconnaissance
aircraft.
