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. [1] It superseded the separate designation systems the Air Force and Navy had for designating US guided missiles and drones, but also a short-lived interim USAF system for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. [2]
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. [3] [4] [5] 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. [6] [7] [8]
The current version of the rocket and missile designation system was mandated by Joint Regulation 4120.15E Designating and Naming Military Aerospace Vehicles [9] [Note 1] and was implemented [10] [Note 2] via Air Force Instruction (AFI) 16-401, Army Regulation (AR) 70-50, Naval Air Systems Command Instruction (NAVAIRINST) 13100.16 on 3 November 2020. [11] 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. [11] [12]
The basic designation of every rocket and guided missile is based in a set of letters called the Mission Design Sequence. [1] 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, Seasparrow, etc. These names are retained regardless of subsequent modifications to the missile.

The United States Armed Forces are the military forces of the United States. The armed forces consist of six service branches: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard. All six armed services are among the eight uniformed services of the United States.
Multiple designation systems have been used to specify United States military aircraft. The first system was introduced in 1911 by the United States Navy, but was discontinued six years later; the first system similar to that used today was designed in 1919 when the US Army's Aeronautical Division became the United States Army Air Service. Before this, aircraft were put into service under their manufacturers' designations.
The Rockwell International Guided Bomb Unit 15 is an unpowered glide weapon used to destroy high-value enemy targets. It was designed for use with F-15E Strike Eagle, F-111 'Aardvark' and F-4 Phantom II aircraft. The GBU-15 has long-range maritime anti-ship capability with the B-52 Stratofortress.
The McDonnell DouglasF-15E Strike Eagle is an American all-weather multirole strike fighter derived from the McDonnell Douglas F-15 Eagle. The F-15E was designed in the 1980s for long-range, high-speed interdiction without relying on escort or electronic-warfare aircraft. United States Air Force (USAF) F-15E Strike Eagles can be generally distinguished from other US Eagle variants by darker aircraft camouflage, conformal fuel tanks (CFTs) mounted along the engine intake ramps and a tandem-seat cockpit.
The Tri-Service aircraft designation system is a unified system introduced in 1962 by the United States Department of Defense for designating all U.S. military aircraft. Previously, the U.S. armed services used separate nomenclature systems.
Joint Regulation 4120.15E: Designating and Naming Military Aerospace Vehicles is the current system for designating all aircraft, helicopters, rockets, missiles, spacecraft, and other aerial vehicles in military use by the United States Armed Forces.
The AGM-129 ACM was a low-observable, subsonic, turbofan-powered, air-launched cruise missile originally designed and built by General Dynamics and eventually acquired by Raytheon Missile Systems. Prior to its withdrawal from service in 2012, the AGM-129A was carried exclusively by the US Air Force's B-52H Stratofortress bombers.
The People's Liberation Army Rocket Force, formerly the Second Artillery Corps, is the strategic and tactical missile force of the People's Republic of China. The PLARF is the 4th branch of the People's Liberation Army (PLA) and controls China's arsenal of land-based ballistic, hypersonic, cruise missiles—both nuclear and conventional. The armed service branch was established on 1 July 1966 and made its first public appearance on 1 October 1984. The headquarters for operations is located at Qinghe, Beijing. The PLARF is under the direct command of the Chinese Communist Party's Central Military Commission (CMC).
The AGM-158 JASSM is a low detection standoff air-launched cruise missile developed by Lockheed Martin for the United States Armed Forces. It is a large, stealthy long-range weapon with a 1,000-pound (450 kg) armor piercing warhead. It completed testing and entered service with the U.S. Air Force in 2009, and has entered foreign service in Australia, Finland, and Poland as of 2014. An extended range version of the missile, the AGM-158B JASSM-ER, entered service in 2014 as well as an anti-ship derivative, the AGM-158C LRASM, in 2018. By September 2016, Lockheed Martin had delivered 2,000 total JASSMs comprising both variants to the USAF.
The Islamic Revolutionary Guard Corps Aerospace Force, officially known as the Islamic Revolutionary Guard Corps Air and Space Force, is the strategic missile, air, and space force of the Islamic Revolutionary Guard Corps (IRGC). It was renamed from the IRGC Air Force to the IRGC Aerospace Force in 2009.
Space Systems Command (SSC) is the United States Space Force's space development, acquisition, launch, and logistics field command. It is headquartered at Los Angeles Air Force Base, California, and manages the United States' space launch ranges.
The RGM-59 Taurus was an American project, conducted by the United States Navy, that was intended to develop a surface-to-surface missile for use as a fire support weapon during amphibious landings, replacing heavy-caliber naval guns. Developed during the early 1960s, the project was cancelled before any hardware development was undertaken.
The ZBGM-75 Advanced Intercontinental Ballistic Missile, also known as Weapons System 120A (WS-120A), was a program to develop an intercontinental ballistic missile (ICBM), proposed by the United States Air Force in the 1960s as a replacement for the LGM-30 Minuteman as the Air Force's standard ICBM. Funding was not allocated for the program and the project was cancelled in 1967.
The RIM-113 Shipboard Intermediate Range Combat System, or SIRCS, was an advanced surface-to-air missile proposed by the United States Navy in the 1970s. The project failed to be approved for funding and was cancelled in 1979.
RIM-85 was a short-lived project by the United States Navy to develop a surface-to-air missile for the defense of naval vessels. Developed during the late 1960s, the project was cancelled before the start of detailed design work.
RIM-101 was a short-lived project by the United States Navy to develop a surface-to-air missile (SAM) for the defense of naval vessels. Developed during the early 1970s, the project, possibly derived from the RIM-7 Sea Sparrow, was cancelled before the start of detailed design work.
The AGM-84H/K SLAM-ER is an advanced stand off precision-guided, air-launched cruise missile produced by Boeing Defense, Space & Security for the United States Armed Forces and their allies. Developed from the AGM-84E SLAM, the SLAM-ER is capable of attacking land and sea targets medium to long range. The SLAM-ER relies on the Global Positioning System (GPS) and infrared imaging for its navigation and control, and it can strike both moving and stationary targets.
The PL-15 is an active radar-guided long-range air-to-air missile developed by the People's Republic of China.
The Army Nomenclature System is a nomenclature system used by the US Army for giving type designations to its materiel. It is based on MIL-STD-1464A which was released in 1981 and most recently revised on February 22, 2021.
