MGM-13 Mace

The Martin Mace (designated as TM-76 tactical missile until 1963, then as MGM-13 for mobile-launched and CGM-13 for container-launched versions) is a tactical surface-to-surface missile developed from the MGM-1 Matador.

History
Development began in 1954 as an improved version of the MGM-1 Matador. Like the Matador, the Mace was a tactical surface-launched missile designed to destroy ground targets. It was first designed as the TM-76 and later the MGM-13.

Mace was launched from a mobile trailer or a hardened bunker using a solid fuel booster rocket for initial acceleration and an Allison J33-A-41 turbojet for flight. The Goodyear Aircraft Corporation developed ATRAN (Automatic Terrain Recognition And Navigation, a radar map-matching system) in which the return from a radar scanning antenna was matched with a series of "maps" carried on board the missile which corrected the flight path if it deviated from the film map. In August 1952, Air Materiel Command initiated the mating of the Goodyear ATRAN with the MGM-1 Matador. This mating resulted in a production contract in June 1954. ATRAN could not be easily jammed its incorporation into the Mace. ATRAN was not range-limited by line-of sight, but its range was restricted by the availability of radar maps and missile range. Although in time it became possible to construct radar maps from topographical maps.

The Mace was first launched in 1956 and the missile could reach Mach .7 to .85 over a 540-mile range at low level (as low as 750 feet), and 1,285 miles at high altitude. Development of Mace "B" missiles began in 1964, with the "B" having a longer fuselage, shorter wings, and more weight than the "A". In addition, the "B" included a jam-proof inertial guidance system (designated TM-76B) which had a range exceeding 1,300 miles. To enhance mobility, Martin designed the Mace's wings to fold for transport (the Matador's wings were transported separately and then bolted on for flight).

The USAF deployed the Mace in West Germany in 1959, and it served alongside the MGM-1 Matador before the latter phased out in 1962. Six missile squadrons served in Europe (38th Tactical Missile Wing) with just under 200 TM-61s and TM-76s. In South Korea, the 58th Tactical Missile Group became combat ready with 60 TM-61s in January 1959. It ceased operations in March 1962, only a few months after the 498th Tactical Missile Group in December 1961 took up positions in semi-hardened sites on Okinawa.

Development of the "B" missiles began in 1964 and remained operational in Europe and the Pacific. The two squadrons of TM-76B/MGM- 13C continued on active duty in USAFE until December 1969. After being taken offline, some missiles were used as target drones because their size and performance resembled manned aircraft.

Variants

 * Mace A - equipped with ATRAN (Automatic Terrain Recognition And Navigation) terrain-matching radar navigation.
 * Mace B - inertial navigation system, increased range.
