The Scorpion stemmed from a 1945 United States Army Air Forces Army Air Technical Service Command specification ("Military Characteristics for All-Weather Fighting Aircraft") for a jet-powered night fighter to replace the P-61 Black Widow. Bell Aircraft, Consolidated-Vultee, Douglas Aircraft, Goodyear, Northrop and Curtiss-Wright all submitted proposals.

Northrop submitted four different designs, prepared by Jack Northrop's team, including a radical flying wing but settled on the N-24, a slim-bodied aircraft with a cantilevered mid-mounted wing and two Allison J35 turbojet engines with afterburners. It was to have radar and a crew of two, with an armament of four 20 mm (.79 in) cannon in a unique trainable nose turret. One of the unusual aspects of the design was the use of Northrop's "Deceleron", a combination aileron/dive brake/flap that could be accommodated in the slim wing design. The unique feature added to the prototype during development was to become a Northrop trademark, still used today on the B-2 Spirit. Contracts for two prototypes were issued in December 1946, while Douglas with their XF3D-1 Skynight and Curtiss for their XF-87 Blackhawk prototypes also were awarded development contracts.

The major production model was the F-89D, which first flew 23 October 1951 and entered service in 1954. It removed the cannon in favor of a new Hughes E-6 fire control system with AN/APG-40 radar and an AN/APA-84 computer. Armament was two pods of 52 2.75 in (70 mm) "Mighty Mouse" FFAR rockets, for a total of 104.
