Lockheed F-94 Starfire

https://en.wikipedia.org/wiki/Lockheed_F-94_Starfire

The Lockheed F-94 Starfire was a first-generation jet aircraft of the United
States Air Force. It was developed from the twin-seat Lockheed T-33 Shooting
Star in the late 1940s as an all-weather, day/night interceptor. The aircraft
reached operational service in May 1950 with Air Defense Command, replacing the
propeller-driven North American F-82 Twin Mustang in the all-weather interceptor
role.

The F-94 was the first operational USAF fighter equipped with an afterburner and
was the first jet-powered all-weather fighter to enter combat during the Korean
War in January 1953. It had a relatively brief operational life, being replaced
in the mid-1950s by the Northrop F-89 Scorpion and North American F-86D Sabre
interceptor aircraft. The last aircraft left active-duty service in 1958 and Air
National Guard service in 1959.

Built to a 1948 USAF specification for a radar-equipped interceptor to replace
the aging F-61 Black Widow and North American F-82 Twin Mustang, it was
specifically designed to counter the threat of the USSR's new Tupolev Tu-4
bombers (reverse-engineered Boeing B-29). The Curtiss-Wright XF-87 Blackhawk had
been designated to be the USAF first jet night fighter, but its performance was
sub par, and Lockheed was asked to design a jet night fighter on a crash program
basis.[2] The F-94 was derived from the TF-80C (later T-33A Shooting Star) which
was a two-seat trainer version of the F-80 Shooting Star. A lengthened nose area
with guns, radar and automatic fire control system was added. Since the
conversion seemed so simple, a contract was awarded to Lockheed in early 1949,
with the first flight on 16 April 1949. The early test YF-94s used 75% of the
parts used in the earlier F-80 and T-33As.

The primary user of the F-94 were the squadrons of Air Defense Command (ADC),
eventually equipping 26 squadrons of interceptors. The first F-94As were
assigned to the 325th Fighter-All Weather Group at McChord AFB and Moses Lake
AFB, Washington.[8] It replaced the propeller-driven F-82F Twin Mustangs that
were in use by its 317th, 318th and 319th squadrons. The F-82s had been pressed
into interceptor service in 1949 after the Soviet Union displayed the Tupolev
Tu-4 strategic bomber, a reversed-engineered version of the B-29 Superfortress,
some of which had landed and were impounded in the Soviet Far East during World
War II. The F-82Fs proved to be an excellent day/night all-weather interceptor,
with long range, but it lacked any logistics support which resulted in a chronic
shortage of parts. The jet-powered F-94As, however, had shorter legs than the
F-82s and relied more on Ground Control Interception Radar (GCI) sites to vector
them to intruding aircraft.

Once the 317th was equipped in the Pacific Northwest, ADC then re-equipped its
52d Fighter-All Weather Group at McGuire AFB, New Jersey[8] which also flew
F-82Fs and provided air defense of the Northeastern United States. However, it
was during this period that Air Defense Command began dispersing its
Fighter-Interceptor squadrons away from their parent groups to individual bases.
During 1950 and 1951, ADC sent F-94As to squadrons of the 56th Fighter Group[8]
in the upper Midwest to replace its obsolete F-47 Thunderbolts, F-51 Mustangs,
as well as F-80 Shooting Star and F-86A Sabre day jet interceptors.

The F-94A and B models were replaced in the active-duty inventory beginning in
mid-1954 by a combination of the Northrop F-89C/D Scorpion and the North
American F-86D Sabre interceptors.[17] They were sent to Air National Guard
units where they replaced North American F-80C Shooting Stars and F-51D/H
Mustangs, which in most cases marked the end of the line for the venerable
Mustang in United States military service.
