In 1963, the U.S. Department of Defense established a designation system for rockets and guided missiles jointly used by all the United States armed services. It superseded the separate designation systems the Air Force and Navy had for designating US guided missiles and drones, but also a short-lived interim USAF system for guided missiles and rockets.

History

On 11 December 1962, the U.S. Department of Defense issued Directive 4000.20 “Designating, Redesignating, and Naming Military Rockets and Guided Missiles” which called for a joint designation system for rockets and missiles which was to be used by all armed forces services. The directive was implemented via Air Force Regulation (AFR) 66-20, Army Regulation (AR) 705-36, Bureau of Weapons Instruction (BUWEPSINST) 8800.2 on 27 June 1963. A subsequent directive, DoD Directive 4120.15 "Designating and Naming Military Aircraft, Rockets, and Guided Missiles", was issued on 24 November 1971 and implemented via Air Force Regulation (AFR) 82-1/Army Regulation (AR) 70-50/Naval Material Command Instruction (NAVMATINST) 8800.4A on 27 March 1974. Within AFR 82-1/AR 70-50/NAVMATINST 8800.4A, the 1963 rocket and guided missile designation system was presented alongside the 1962 United States Tri-Service aircraft designation system and the two systems have been concurrently presented and maintained in joint publications since. The current version of the rocket and missile designation system was mandated by Joint Regulation 4120.15E Designating and Naming Military Aerospace Vehicles and was implemented via Air Force Instruction (AFI) 16-401, Army Regulation (AR) 70-50, Naval Air Systems Command Instruction (NAVAIRINST) 13100.16 on 3 November 2020. The list of military rockets and guided missiles was maintained via 4120.15-L Model Designation of Military Aerospace Vehicles until its transition to data.af.mil on 31 August 2018.

Explanation

The basic designation of every rocket and guided missile is based in a set of letters called the Mission Design Sequence. The sequence indicates the following: Examples of guided missile designators are as follows: The design or project number follows the basic designator. In turn, the number may be followed by consecutive letters, representing modifications. In addition, most guided missiles have names, such as Harpoon, Tomahawk, Sea Sparrow, etc. These names are retained regardless of subsequent modifications to the missile.

Prefixes

Additionally, a prefix may be added to the designation indicating a non-standard configuration. For example:
