The original author of this article seems to have believed that the 4.5 and the 4.7 were the same gun. As far as is known the 4.5 was first introduced in the late 1930s as the main gun for carriers, and was first used on destroyers around 1942.

The first documented use in a destroyer that I have been able to discover was HMS Savage - commissioned June 1943 with a Mk II twin mount in 'A' gun position and single Mk V mounts in 'X' and 'Y' gun positions.

By comparison the 'L's commissioned starting in August 1941 with the Mk XI 4.7 inch.

Could someone with access to more detailed information on the 4.5 check please, especially the statements regarding gun crews which seem to relate more to early 4.7 marks.

[edit] Naming

So far I have found reference to the 5"/55 (11.4 cm) Mark 8 gun first used on HMS Bristol int he 70's that succeeded the 4.5"/45 (11.4 cm) QF Mark V which started service in 1945. GraemeLeggett 15:46, 18 July 2005 (UTC)

And they followed the 4.5"/45 (11.4 cm) QF Marks I, III and IV from the 1930s GraemeLeggett 15:47, 18 July 2005 (UTC)
