Northrop P-61 Black Widow

The Northrop P-61 Black Widow is a twin-engine United States Army Air Forces fighter aircraft of World War II. It was the first U.S. aircraft conceived from the outset and deployed operationally specifically as a night fighter, incorporating onboard radar as part of the original airframe design. Named for the North American spider Latrodectus mactans, it was an all-metal, twin-engine, twin-boom design armed with four forward-firing 20 mm (.79 in) Hispano M2 autocannon in the lower fuselage, and four .50 in (12.7 mm) M2 Browning machine guns in a dorsal gun turret.
