Gimlet (rocket)
The Gimlet was an unguided air-to-air and air-to-surface rocket developed by the United States Navy during the early 1950s. Although it proved successful in testing and was ordered into large-scale production, the arrival of the guided missile as a practical and reliable weapon resulted in the cancellation of the Gimlet rocket in 1957.
==Design and development==
The development of the Gimlet rocket began in 1951, with the initiation of development of a rocket for air-to-air use.〔Babcock 2008, p. 210.〕 Work on the rocket was conducted at the Naval Ordnance Test Station (NOTS) at China Lake, California, and the project was begun at the behest of North American Aviation.〔 in addition, the 1.5-inch rocket was felt as the ideal caliber to 'fill in a gap' in the U.S. Navy's rocket inventory;〔 studies indicated that aircraft could carry six times the number of 1.5-inch rockets as opposed to the then-in-service Folding Fin Aerial Rocket.〔Babcock 2008, p. 211.〕
In 1952, however, the Bureau of Ordnance decided that neither the 1.5-inch or 2.75-inch rocket was required; an earlier directive to develop a rocket was still outstanding, and it was felt that standardizing on a single caliber of rocket would be in the Navy's best interest.〔 NOTS had initiated development of a rocket of the 2-inch caliber prior to the outbreak of the Korean War; the concept had been shelved with the war effort requiring higher-priority projects such as the Ram anti-tank rocket to be prioritized; now, however, the project was dusted off and development resumed under the name "Gimlet"〔 – a name that, it was said, meant the rocket was to be a "small anti-MiG" weapon; "Gim" being "MiG" backwards, with an added diminutive.〔Babcock 2008, p. 536.〕
Gimlet was primarily intended for use in the air-to-air role.〔Carelone 1993, p. 39.〕 The rocket would use a modified version of the FFAR's fuse, reduced in size to fit the smaller rocket;〔 the warhead used for Gimlet took advantage of the latest advancements in explosives technology, and, combined with the advanced fuse, would detonate inside the target aircraft, instead of upon contact.〔Babcock 2008, p. 212.〕 The rocket used a thin-walled aluminum body, also based on FFAR work;〔 the motor used an eight-point star configuration to ensure even burning.〔Babcock 2008, p.213.〕
