Locations

Cartagena: 4 Guns. Batteries Castillitos and Cenizas, each with 2 guns (Guns still in situ).

Ferrol and A Coruña: Originally 8 guns. Batteries at Cape Prior (Guns scrapped 1997), Monte San Pedro (Guns still in situ), Campelo Alta (Guns transferred 1941) and Lobateiras (Guns removed), each with 2 Guns.

Menorca: Originally 6 guns. Batteries at Favarix (Guns transferred 1944), Mahon and Llucalary (guns still in situ), each with 2 guns.

Subsequently, the guns at Campelo Alta were moved to a new location at Paloma Alta, work being completed in October 1941. One of these guns was destroyed when it suffered a premature detonation during Proof Firing. Later the two guns from the Favarix Battery were transferred, becoming operational in January 1944. These three guns remained in service until 2008, when the last one finally retired into reserve.
