Mk 4 Terrier GMLS

History

The Mk 4 GMLS was fitted on the Baltimore class cruisers Boston and Canberra, replacing the aft gun turrets. The first installation was commissioned in 1955. In 1961 the first non-US Navy installation was commissioned, the Italian Missile cruiser Giuseppe Garibaldi. This was also a conversion of a former gun cruiser. The Boston and Canberra installations were decommissioned in 1970, followed by the Italian installation in 1971.

The GMLS was used only with the early RIM-2A and RIM-2B Terrier missiles.

The Mk 4 is the only Terrier GMLS where the missiles were stored vertically. The magazine of both Mod 1 and Mod 0 had an capacity of 74 missiles. Mod 1 was the superfiring installation, and was identical to the Mod 0 except for an lengthened loader rail.
