Geocache Description:

Military aircraft series.

This should be a nice easy park and grab. I am making this a small as it is one of my favorite fighter aircraft of WWII.

Northrop P-61 Black Widow

The Northrop P-61 Black Widow was the first operational U.S. military aircraft designed specifically for night interception of aircraft, and was the first aircraft specifically designed to use radar. It was an all-metal, twin-engine, twin-boom design developed during World War II. The first test flight was made on 26 May 1942, with the first production aircraft rolling off the assembly line in October 1943. The last aircraft was retired from government service in 1954.

Although not produced in the large numbers of its contemporaries, the Black Widow was effectively operated as a night-fighter by United States Army Air Forces squadrons in the European Theater, the Pacific Theater, the China Burma India Theater and the Mediterranean Theater during World War II. It replaced earlier British-designed night-fighter aircraft that had been updated to incorporate radar when it became available. After the war, the F-61 served in the United States Air Force as a long-range, all weather, day/night interceptor for Air Defense Command until 1948, and Far East Air Force until 1950.

On the night of 14 August 1945, a P-61B of the 548th Night Fight Squadron named "Lady in the Dark" was unofficially credited with the last Allied air victory before VJ Day. The P-61 was also modified to create the F-15 Reporter photo-reconnaissance aircraft for the United States Air Force.
