As a night fighter that was not expected to be as agile as smaller daylight fighters; the expectation was to be a stable platform for its radar system and the four 20 mm cannon mounted in the lower fuselage.

.)

The radar system in the F3D-1 was the Westinghouse AN/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 fire control radar, both located in the nose, and an AN/APS-28 tail warning radar. The complexity of this radar system, which was produced before the advent of semi-conductor electronics, required intensive maintenance to keep it operating fully.

First flight of the XF3D-1 occurred on 23 March 1948. A production contract for 28 F3D-1 production aircraft soon followed in June 1948. 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 lead to F3D-2 aircraft being fitted with J34-WE-36 engines instead. The F3D-2 also incorporated an improved Westinghouse AN/APQ-36 radar 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

The few F3D-1 aircraft were used primarily to train F3D crews and did not see combat. F3D-2 aircraft, however, saw extensive service during the Korean War

. While the Skyknight lacked the swept wings and high subsonic performance of the MiG-15, its onboard radar enabled it to find and kill other fighters, while the MiG-15 could only be guided by ground-based radar to the general vicinity of large B-29 formations.

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.

The F3D-2M was the first operational Navy jet aircraft to be fitted with an air-to-air missile, the Sparrow I, a missile that used beam riding guidance for the aircrew to control the flight of the missile. Only 38 aircraft (12 F3D-1Ms, and 16 F3D-2Ms) were made able to use the missiles.

In the late 1950s, a number of the Marine F3D-2 aircraft were re-configured as electronic warfare aircraft and were designated F3D-2Q (later EF-10B). Also, a few aircraft were converted for use as trainers and were designated F3D-2T.
Skyknights continued service through the 1960s in 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. The Skyknight was the only Korean war fighter that also flew in Vietnam (as also did the A-1 Skyraider

, essentially an updated and enlarged F3D that would carry the AAM-N-10 Eagle long-range 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. Its weapon system would be adapted for the supersonic swing-wing General Dynamics/Grumman F-111B

 which also specified side-by-side seating, but would also prove vulnerable to MiGs. The AWG-9/Phoenix and TF30 turbofan engine (with afterburner) would eventually reach service on the F-14 Tomcat which could swing its wing straight forward for loiter.

The unusual portly profile earned it the nickname "Willie the Whale". It is less clear how it also came to be known "drut." It should be noted, however, that "Drut" is "Turd" spelled backward.
