Talk:QF 4.5-inch Mk I – V naval gun

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.

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)

Infobox?
This article could use one. The applicable infobox is Infobox Weapon, as seen here: 5"/38 caliber gun. -MBK004 04:32, 16 January 2009 (UTC)

Picture at top at St Kilda ??
The picture at the top apparently from Dùn et le Loch Hiort, Saint-Kilda, looks like a QF 12 pounder 12 cwt or something very like it to me. Rcbutcher (talk) 04:34, 16 January 2009 (UTC)

Ammunition
I'd guess that a direct action fuze (eg No 118?) was available to RN in WW2 in addition to time fuze(s) for AA. Was the same shell and propelling charge used throughout the service life of the gun? I'd also guess that after WW2 new fuzes were introduced not least a UK proximity fuze, if a US VT fuze became available in 1944 presumably it was T98 or perhaps T100.Nfe (talk) 04:04, 28 February 2010 (UTC)

Unfortunately while I have a ref for the thing existing it doesn't explicitly state the current location:
