Having observed the conversion to be relatively straightforward, USAF officials chose to issue a letter contract to Lockheed during January 1949. Months later, a definitive contract for 150 production aircraft was received.

[Knaack 1982, pp. 101-102.] To accelerate development, these early test aircraft were converted from existing T-33s; they maintained roughly 75% commonality in terms of components with those used in the earlier F-80 and T-33As.
[Pace 2016, p. 44.] Flight testing determined the test aircraft to possess adequate performance.
[Pace 2016, p. 48.] By the end of 1949, the program had been restructured to fulfil pressure from the USAF for more capable fighters; an more austere model, the F-94A, would be delivered quickest while a more capable and ambitious model, the F-94C, was produced.

["Technical Gen". ''RAF Flying Review'', September 1962, p. 59.] The combination of added weight and the use of an afterburner considerably reduced the F-94's internal fuel capacity. The YF-94A's afterburner suffered numerous teething problems, typically related to its igniter and the flame stabilization system.

Production versions
F-94A
The initial production model was the F-94A, which entered operational service in May 1950. Its armament was four 0.50 in (12.7 mm) M3 Browning machine guns mounted in the fuselage with the muzzles exiting just behind the radome
A radome (a portmanteau of "radar" and "dome") is a structural, weatherproof enclosure that protects a radar antenna (radio), antenna. The radome is constructed of material transparent to radio waves. Radomes protect the antenna from weathe ...
. Two drop tanks, as carried by the F-80 and T-33, could be carried beneath the wingtips. Alternatively, these could be replaced by bombs, giving the aircraft a secondary fighter bomber role.[Francillon 1982, p. 294.] 109 F-94As were produced. This model was only in operational service for a brief time as it was originally built and was not received well by its aircrews. The main source of complaints was its somewhat unreliable J33 engine, which frequently necessitated ground aborts and had been deemed by many crews to be unsafe.[Knaack 1982, pp. 102-103.] In flight, the aircraft was often judged to be unstable and difficult to maneuver when flown at high altitude by its pilots. The pilot and radar operator commonly found that the cockpit was too narrow for them to be able to quickly enter and exit the aircraft, which was routinely expected during alerts and scrambles.[Knaack 1982, p. 103.] Furthermore, the clearance for the ejection seat
In aircraft, an ejection seat or ejector seat is a system designed to rescue the aircraft pilot, pilot or other aircrew, crew of an aircraft (usually military) in an emergency. In most designs, the seat is propelled out of the aircraft by an exp ...
s was too small, resulting in several tragic accidents during emergency ejections.[Isham and McLaren (1993) Lockheed F-94 Starfire, A Photo Chronicale, Schiffer Publishing, Ltd, ]
F-94B
During January 1951, the improved F-94B entered service; it was outwardly virtually identical to the F-94A.[Knaack 1982, p. 104.] The Allison J33 engine had received several modifications to make it considerably more reliable. The pilot was also provided with a more roomy cockpit while the canopy was replaced by a redesigned unit with a bow frame in the center between the two crew members, along with a new Instrument Landing System (ILS).[Knaack 1982, pp. 103-104.] 356 F-94Bs were completed. It proved to be a fairly reliable aircraft, particularly in comparison to its predecessor, and encountered relatively few problems during its service life. This improved model quickly replaced the F-94As in service with the active-duty squadrons, after which these older aircraft were temporarily returned to Lockheed to be re-engined and rebuilt to F-94B standards. These upgraded F-94A/B aircraft were also modified with a twin-gun pod under each wing for two additional 0.50 in (12.7 mm) machine guns each, bringing the total to eight. These aircraft were then passed along to Air National Guard units where they served until the end of the 1950s.
F-94C
The F-94C Starfire was extensively modified from the early F-94 variants. In fact, it was initially designated F-97 before officials decided that it would be treated as a new version of the F-94 instead.[Knaack 1982, p. 106.] At the time, USAF interest in the aircraft was allegedly lukewarm, thus Lockheed opted to fund development themselves, converting two F-94B airframes into YF-94C prototypes for evaluation. To improve performance, a completely new and much thinner wing was designed, along with a swept tail surface. The J33 engine was replaced with a more powerful Pratt & Whitney J48, a license-built version of the afterburning Rolls-Royce Tay, which dramatically increased power over the J33, producing a dry thrust of and approximately with afterburning.[Pace 2016, p. 49.] The fire control system was upgraded to the new Hughes E-5 with an AN/APG-40 radar, a change which required the use of a much larger nose. All of the guns were removed and replaced with all-rocket armament consisting of four groups of six rockets in a ring around the nose.[Pace 2016, p. 51.] These rockets were carried in four panels that could be hinged upwards and outwards for ground reloading.[Knaack 1982, pp. 106-107.] In flight, these rockets were normally hidden aft of four inwards-folding doors that surrounded the nose cone. According to Lockheed test pilot Tony LeVier, the F-94C was capable of supersonic flight in a steep dive with afterburner engaged.
The F-94C was the only variant to be officially named Starfire. With time, the entire F-94 family has adopted the name. The first production F-94C aircraft were delivered in July 1951, 387 examples being delivered before May 1954. The largest problem discovered in service was the nose-mounted rockets, which blinded the crew with their smoke and fire. The most severe problem associated with firing the nose-mounted rockets was that the exhaust could cause a flameout of the jet engine, which could lead to the loss of the aircraft.[Knaack 1982, pp. 107-108.] After the 100th aircraft, mid-wing rocket pods were added to the leading edges, similar in concept to the previous gun pods, holding 12 rockets apiece and fitted with a frangible aerodynamic nose cap which was discarded when firing the rockets. Most of the time, the nose rockets were not fitted, and the mid-wing pod rockets were the sole armament. This version of the aircraft was extensively used within the Semi Automatic Ground Environment

(SAGE) air defense system.
F-94D
An F-94D model was proposed as a single-seat fighter bomber, being armed with both bombs and rockets under the wings as well as eight nose-mounted machine guns. A single prototype was built, but the model was not ultimately accepted for production. The prototype was later used as a testbed for the 20 mm (0.79 in) M61 Vulcan

, 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 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 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.

Beginning in the summer of 1951, the F-94Cs began coming off the production line, with six squadrons being equipped by May 1954. Five more squadrons were equipped in FY 54-55 which ended the production run for the interceptor by Lockheed.[Baugher Lockheed F-97/F-94C Starfire](_blank)

In early December 1951, the appearance of Communist MiG-15 jets over Seoul raised alarm bells at FEAF Headquarters. The only interceptors over Seoul were about six F-82Gs along with some Marine Grumman F7F Tigercats. FEAF ordered the 68th to move two F-94Bs to Suwon to supplement the F-82s. The F-82s along with the F7Fs would continue their armed reconnaissance and weather missions against North Korean targets, while the F-94s would fly interception missions over South Korea and the Yellow Sea

In March 1952, the 319th FIS began flying operational missions at Suwon, providing Combat Air Patrols (CAPs) for B-29 missions at night.[Knaack 1982, pp. 104-105.] The 68th was relieved and reassigned to Japan, but would remain on one-hour alert for possible combat duty over Korea. In June, the first F-94 contacts against enemy jets was made and the interceptor crews believed at the time that the communists were testing radar-warning equipment. On several occasions just when they were ready to fire on the enemy aircraft, it would start evasive action that indicated the MiGs were equipped with a form of warning radar (as the F-94s were). Other intercepts would take place over North Korea and the F-94 was credited with several air-to-air victories, including the first jet-vs.-jet night victory against a MiG-15. One F-94 was listed as lost due to enemy action, six more to non-enemy causes on combat missions, two were declared as missing on a combat mission and three were lost in accidents. One F-94 was lost when it slowed to during pursuit of a Po-2 biplane.
Following the Armistice in Korea in June 1953, the F-94s continued to fly air defense missions over Japan and South Korea. Beginning in 1954, the F-86D Sabre began replacing it in operational service. By the end of 1954, the Starfires had been returned to the United States for Air National Guard duty.

. Chains of Ground Control Radar sites were established under Alaskan Air Command (AAC), the postwar successor to Eleventh Air Force, and P-61 Black Widows were sent in 1948 as long distance interceptor aircraft. The F-82H Twin Mustang replaced the war-weary P-61s during 1949.
These propeller-driven interceptors were augmented in 1950 when the 449th Fighter-All Weather Squadron at Ladd AFB began receiving F-94As in mid-1950s. The squadron was divided into the F-82 flight and the F-94 flight as the jet interceptors doubled the squadron in size.[Thompson, Warren E (October 2003). "Alaskan Twin Mustangs, North American F-82 Operations in Alaska". Wings (Sentry Books)] In Anchorage, the 57th Fighter Group at Elmendorf AFB began sending its F-80C Shooting Stars back to the Continental United States in batches of four or five as they were replaced by the F-94As.

in the south had much more moderate weather than Ladd AFB, located in Central Alaska where winter temperatures often fell below . Hydraulic fluids would turn to jelly, and the engines in the jets would have starting problems. Extreme cold weather training for Air Force personnel assigned to Ladd AFB was mandatory in the event of an emergency ejection or even just being outside in the winter, losing a glove, and dropping a wrench or tool. Skin would freeze upon touching bare metal, and mechanics would have tools "welded" to their fingers at times.
The 449th utilized its F-82Hs as long-range reconnaissance aircraft along the Siberian coastline and the Chukchi Peninsula
The Chukchi Peninsula (also Chukotka Peninsula or Chukotski Peninsula; , ''Chukotskiy poluostrov'', short form , ''Chukotka''), at about 66° N 172° W, is the easternmost peninsula of Asia. Its eastern end is at Cape Dezhnev near the village ...
. Also the F-82s were flown in a ground support role during maneuvers with the Army forces. They would also drop bombs on frozen rivers to break up ice floes. For these missions, the F-94 was totally unsuitable and it also did not have the range for the long distance reconnaissance flights necessary to monitor the Siberian coast. Alaska was divided into two areas, the northern part under the 11th Air Division, headquartered at Ladd AFB, and had control of the GCI sites in the northern half of the territory. The 57th Fighter Group, based at Elmendorf AFB, was responsible for everything south. In April 1953, the 57th FIG was inactivated and the three squadrons F-94s at Elmendorf AFB became part of the 10th Air Division. Both the 449th FIS and the 57th FIG deployed the F-94s to advance airfields at Marks AFB, near Nome, along with King Salmon Airport and Galena AFB where it stood alert to respond to GCI intruder alerts for unknown aircraft detected intruding on Alaskan airspace.
The F-82Hs at Ladd were retired in the summer of 1953 when due to lack of logistics support, the aircraft became too unreliable to keep in the air. The 449th flew the F-94A until F-94Bs became available as hand-me-downs from Elmendorf AFB the 57th FIG was inactivated replaced by the 10th Air Division. There, the 10th AD received new North American F-86D Sabre interceptors. The 449th at Ladd sent their F-94As back to the CONUS and Air National Guard

Service. By the end of 1954, it also was being re-equipped with F-86Ds, with the last of the Starfires also being sent to the Air National Guard.
Northeast Air Command
Northeast Air Command (NEAC) was a command formed in 1950 to administer US-controlled bases in the Maritime Provinces of Canada, that were under long-term lease going back to World War II. It was responsible for the defense of the northern approaches to North America and also to support transient aircraft of MATS and SAC, all of which came under the collective command and control of the 64th Air Division.[US Air Defense in the Northeast, Lydus H. Buss, USAF Continental Air Defense Command, 1957](_blank)
During 1952, F-94Bs were sent to the 59th Fighter-Interceptor Squadron at Goose AFB, Labrador from Otis AFB, Massachusetts; furthermore, a detachment of the 59th was sent to Thule Air Base

over the North Pole. This was both the first F-89 squadron assigned to Canada and also the first squadron assigned to NEAC.[. LCCN 70605402]
After the end of the Korean War, the 319th FIS, which was deployed from ADC to Japan in 1952, was transferred to NEAC in June 1953 and replaced the detachment of the 59th FIS at Thule. The third and last F-94 squadron assigned to NEAC was the 61st Fighter-Interceptor Squadron, which moved from Selfridge AFB, Michigan to Ernest Harmon AFB, Newfoundland in August 1953. Beginning in 1954, and continuing until 1957, the Starfires of NEAC were slowly replaced with versions of the F-89 Scorpion, although the Northrop interceptor didn't fully replace the Starfires until the 318th Fighter-Interceptor Squadron left Thule in April 1957.

in April 1953. It provided air defense of Iceland until being relieved in October 1954 when it was reassigned to Presque Isle AFB, Maine. The Starfires were replaced by the 57th FIS and F-89C Scorpions.
Retirement
Beginning in mid-1954, the F-94A/B models were gradually replaced in the active-duty Air Force's inventory by a combination of the Northrop F-89C/D Scorpion and the North American F-86D Sabre interceptors. Withdrawn aircraft were typically sent to various Air National Guard (ANG) units where they replaced F-80C Shooting Stars and F-51D/H Mustangs, which in most cases marked the end of operational use for the venerable Mustang in United States military service. Prior to being delivered to the ANG, the F-94As were sent to Lockheed, where they received modifications to render them equivalent to F-94B standards, after which they entered use with the ANG. During the late 1950s, F-94Cs were progressively transferred across to the ANG as well, where they initially supplemented and eventually replaced the F-94A/B models. At the height of operations, a total of 22 ANG Fighter-Interceptor squadrons were equipped with Starfires.
During November 1957, the final F-94C was retired by the active-duty Air Force, the last examples being operated by the 319th Fighter-Interceptor Squadron at Bunker Hill Air Force Base, Indiana, before it converted to the F-89J Scorpion interceptor. The last F-94C Starfires were phased out of ANG service by the 179th Fighter-Interceptor Squadron at the Duluth Municipal Airport, Minnesota during the summer of 1959 when it converted to the F-89J Scorpion; the last aircraft being sent to AMARC
