The Douglas F3D Skyknight (later designated F-10 Skyknight) was a United States twin-engine, mid-wing jet fighter aircraft manufactured by the Douglas Aircraft Company in El Segundo, California. The F3D was designed as a carrier-based all-weather night fighter and saw service with the United States Navy and United States Marine Corps. The mission of the F3D-2 was to search out and destroy enemy aircraft at night.[1] The F3D Skyknight was never produced in great numbers but it did achieve many firsts in its role as a night fighter over Korea. While it never achieved the fame of the North American F-86 Sabre, it did down several Soviet-built MiG-15s as a night fighter over Korea with only one air-to-air loss of its own against a Chinese MiG-15 on the night of 29 May 1953.[2][3] The Skyknight played an important role in the development of the radar guided AIM-7 Sparrow missile which lead to further guided air-to-air missile developments. It also served as an electronic warfare platform in the Vietnam War as a precursor to the EA-6A Intruder and EA-6B Prowler. The aircraft is sometimes unofficially called "Skynight", dropping the second "k". The unusual, portly profile earned it the nickname "Willie the Whale".[4] Some Vietnam War U.S. Marine veterans have referred to the Skyknight as "Drut" whose meaning becomes obvious when read backward. This may be in reference to its age, unflattering looks or its low slung intakes that made it vulnerable to foreign object damage (FOD).[5]
Design and development[]
The F3D was not intended to be a typical sleek and nimble dogfighter, but as a stand off night fighter, packing a powerful radar system and second crew member. It originated in 1945 with a U.S. Navy requirement for a jet-powered, radar-equipped, carrier-based night fighter. The Douglas team led by Ed Heinemann designed around the bulky air intercept radar systems of the time, with side-by-side seating for the pilot and radar operator.[6] The result was an aircraft with a wide, deep, and roomy fuselage. Instead of ejection seats, an escape tunnel was used, similar to the type used in the A-3 Skywarrior.[6]
The XF3D-1 beat out Grumman Aircraft Engineering Corporation's G-75 two-seat, four engine, Westinghouse J30 powered night fighter design and was issued a contract 3 April 1946. The U.S. Navy's Bureau of AeronauticsBuAer also issued a contract to Grumman for two G-75 (company designation) XF9F-1 (BuAer designation) experimental aircraft on 11 April 1946 in case the Skyknight ran into problems. Grumman soon realized the G-75 was a losing design but had been working on a completely different, single-engine, day fighter known as the Grumman G-79 which became the F9F Panther.[7][N 1]
The first flight of the XF3D-1 was on 23 March 1948 at Douglas' El Segundo facility with test pilotRussell Thaw at the controls.[N 2] Further flight testing followed at El Segundo until October 1948. Three prototypes where then taken to Muroc Air Force Base (later renamed Edwards Air Force Base) for service trials. Power was provided by two 1945 design Westinghouse J34-WE-24 turbojets of 3,000 lbf (1,361 kgf) mounted in the roots of then-standard straight wings of the early jet era. A production contract for 28 F3D-1 J34-WE-32 powered production aircraft was issued in June 1948 with the first production aircraft becoming airborne 13 February 1950.[11] As a night fighter that was not expected to be as fast as smaller daylight fighters, the expectation was to have a stable platform for its radar system and the four 20 mm cannon mounted in the lower fuselage. The F3D was, however, able to outturn a MiG-15 in an inside circle.[12] The fire control system in the F3D-1 was the advanced for the time WestinghouseAN/APQ-35. The AN/APQ-35 was a combination of three different radars, each performing separate functions: an AN/APS-21 search radar, an AN/APG-26 tracking radar, both located in the nose, and an AN/APS-28 tail warning radar.[13] The complexity of this vacuum tube-based radar system, which was produced before the advent of semiconductor electronics, required intensive maintenance to keep it operating properly.
The F3D-1 was followed by the F3D-2, which was first ordered in August 1949. The F3D-2 was intended to have Westinghouse J46 engines in enlarged nacelles to replace the J34-WE-32 engines of the F3D-1. Development problems with the J46 led to the F3D-2 initially being fitted with J34-WE-36 engines instead. Higher thrust J34-WE-38 engines would be installed later which increased aircraft performance.[11] The F3D-2 also incorporated an improved Westinghouse AN/APQ-36 fire control system. A total of 237 F3D-2s were built before production ended on 23 March 1952. A higher performance F3D-3 version with swept wings and J46 engines was planned, but was cancelled when the trouble-plagued J46 engine program was terminated.
Operational history[]
Korean War[]
The 28 F3D-1 aircraft were used primarily to train F3D crews and did not see combat in the Korean War. The F3D-2 Skyknight was only deployed to Korea by USMC land based squadrons, beginning in September 1952.[14] The Skyknight shot down more enemy aircraft in Korea than any other single type of naval aircraft.[15] The first air-to-air victory occurred on the 2 November 1952 at night in a USMC F3D-2 piloted by Major William T. Stratton, Jr., and his radar operator, Master Sergeant Hans C. Hoglind of VMF(N)-513 Flying Nightmares.[16] Major Stratton shot down what he believed was a Yakovlev Yak-15 (even though no Yak-15s were reported in Korea)[5] on 2 November 1952 which was the first successful night radar interception by a jet of a jet.[17] The Skyknight claimed its first MiG-15 jet fighter on 8 November 1952, when Captain O.R. Davis and Warrant Officer D.F, "Ding" Fessler shot down a MiG-15 northwest of Pyongyang.[17] USMC pilot Lt. Joseph Corvi and his radar operator Sergeant Dan George set another record with the Skynight on the night of 10 December 1952. They shot down the first aircraft by an aircraft with a radar track and lock-on and without visual contact by using their radar to lock on their 20mm cannons to down a Polikarpov Po-2 biplane. They were also credited with another probable that night.[18] The number of USMC Skyknights in Korea was doubled in January 1953 to 24 which allowed them to effectively escort B-29 Superfortresses on night bombing missions.[19] On 12 January 1953, an F3D-2 of VMF(N)-513 that was escorting B-29s on a night bombing mission was vectored to a contact and shot down the fourth aircraft by a Skyknight.[12] By the end of the war, Skyknights had claimed six enemy aircraft shot down (one Polikarpov Po-2, one Yakovlev Yak-15 and four MiG-15s).[16] There was the loss of one aircraft by enemy fire which was piloted by LTJG Bob Bick and his crewman, Chief Petty Officer Linton Smith, on 2 July 1953. This aircraft was with a detachment from Fleet Composite Squadron FOUR (VC-4) at NAS Atlantic City, and was attached to U.S. Marine Fighter Squadron 513 (VMF(N)-513).[20] While the Skyknight lacked the swept wings and high subsonic performance of the MiG-15, its powerful fire control system enabled it to find and kill other fighters at night, while most MiG-15s could only be guided by ground-based radar.
Post Korean War[]
In the years after the Korean War, the F3D was gradually replaced by more powerful aircraft with better radar systems. The F3D's career was not over though; its stability and spacious fuselage made it easily adaptable to other roles. The F3D (under the designations F3D-1M and F3D-2M) was used to support development of a number of air-to-air missile systems during the 1950s, including the Sparrow I, II, and III and Meteor missiles.[21] The Sparrow missile was developed at Naval Air Missile Test Center now thePacific Missile Test Center PMTC and early test firings were conducted at Naval Ordinance Test StationChina Lake (now Naval Air Weapons Station China Lake) California.
In 1954, the F3D-2M was the first U.S. Navy jet aircraft to be fitted with an operational air-to-air missile: the Sparrow I,[22] an all weather day/nightBVR missile that used beam riding guidance for the aircrew to control the flight of the missile. Only 38 aircraft (12 F3D-1Ms,[23] and 16 F3D-2Ms[24]) were modified to use the missiles.
In the late 1950s, a number of the U.S. Marine F3D-2 aircraft were re-configured as electronic warfare aircraft and were designated F3D-2Q (later EF-10B). A few aircraft were also converted for use as trainers and were designated F3D-2T.
When the U.S. Navy issued a requirement for a fleet defense missile fighter in 1959, Douglas responded with theF6D Missileer, essentially an updated and enlarged F3D that would carry the AAM-N-10 Eagle long-range air-to-air missile with the most important characteristics being able to carry a large load of fuel, long time-on-station, crew of two, and sophisticated electronics rather than speed or maneuverability. This concept which kept the straight wings in an age of supersonic jets was soon cancelled because it would not be able to defend itself against more nimble fighters.[25][26] Its weapon system would be adapted for the supersonic swing-wing General Dynamics-Grumman F-111B, the U.S. Navy version of a joint USAF/USN tactical jet aircraft which also specified side-by-side seating. The USAF version would eventually see service as an air-to-ground fighter bomber, but the USN version, envisioned as a Fleet Air Defense fighter and dogfighter, would be cancelled when it was clear that its performance was not sufficient for an air-to-air dogfighter role. The AWG-9/Phoenix and TF30 turbofan engine would eventually enter service on the F-111B's successor, the swing-wing Grumman F-14 Tomcat.
Skyknights continued in service through the 1960s in a gull white color scheme, when their contemporaries had long since been retired. In 1962, when the U.S. Navy and U.S. Air Force unified their designation systems, the F3D-1 was redesignated F-10A and the F3D-2 was re-designated F-10B.
Vietnam War[]
The Skyknight was the only Korean war jet fighter that also flew in Vietnam. EF-10Bs served in the Electronic warfare role during the Vietnam War until 1969. The large interior provided an ample amount of room for electronic equipment. U.S. Marine Composite Reconnaissance Squadron One VMCJ-1 Golden Hawks began operating the EF-10B in Vietnam on 17 April 1965 under Lt. Col Wes Corman at Da Nang Air Base Republic of Vietnam with six aircraft.[27] No more than 10 EF-10Bs were in Vietnam at one time. The Electronic Warfare (EW) Skyknight was a valuable Electronic countermeasure (ECM) asset to jam the SA-2 surface-to-air missiles (SAM) tracking and guidance systems.[5] VMCJ-1 made history when its EF-10Bs conducted the first USMC airborne radar jamming mission on 29 April 1965 to support a USAF strike mission. Four EF-10Bs also supported a massive strike on the SA-2 SAM sites near Hanoi on 27 July 1965. Many U.S. aircraft were lost to SA-2 surface-to-air missiles in Vietnam and the electronic attack on the associated radar systems was known as "Fogbound" missions. The F3D also dropped chaff over the radar sites.[5] The first EF-10B lost in Vietnam was to a SA-2 SAM on 18 March 1966, while four more EF-10Bs were lost in Vietnam to accidents and unknown causes.[27] Their mission was gradually taken over by the more capable "Electric Intruder", (EW)/Electronic countermeasures variant of theGrumman A-6 Intruder. The EF-10B Skyknight continued to fly lower threat EW missions until they were withdrawn from Vietnam in October 1969.[27] The EKA-3 Skywarrior and the Douglas RB-66 Destroyer also took on EW missions. The U.S. Marine Corps retired its last EF-10Bs in May 1970.[28] Some aircraft continued flying as testbeds for Raytheon until the 1980s.[29]
