Hey all, was wondering if anyone had any good photos or information about the 3 inch Anti-aircraft gun? Apparently it was the first British dedicated AA gun and introduced in 1914. Seen a few small blurry black and white photos of them on the back of trucks defending London against Zeppelin's/Gotha's/Staaken's but that's all. Also interested as to whether anyone knows of any preserved ones (Think there might be one at the Royal Artillery Museum in Woolwich, East London) or any models of them as well. Here's the only decent picture of one I could find on the internet
Hi dont know about 3inch aa guns but a while ago i came across this page on surviving Artillery Pieces on Public Display in New England of course it only really usefull if you live in the states but there is some interesting survivors there including 2 hotchkiss revolving cannons and many WW1 guns.....
Some further searching brought up this link which has a small pic of a 3" AA gun mounted on truck..although this claims to be a dedicated AAgun i suspect its based on the 12pdr QF guns commonally found on pre-dreadnoughts and some dreadnoughts as anti torpedo boat guns.....
Ian Hogg discusses this weapon in 'Allied Artillery of World War One' (which I highly recommend).
The 3in 20cwt AA gun was the first dedicated AA gun designed in Britain, and was designed to a Royal Navy request and specification, the request dating from 1911. As such it was fitted on Royal Navy vessels, including dreadnoughts (HMS Iron Duke, Jellicoe's flagship at Jutland, was the first to receive a pair), and was also used by the Army, often fitted to Peerless trucks (it is not to be confused with a large number of 13pdr guns on extemporised high angle mountings).
The original Mk I gun had a very ingenious semi-automatic breechblock, but the complexity of manufacture led to its abandonment in favour of a screwbreech.
Being a naval gun, there is a page on NavWeaps about it:
Four GAs plus gun and breech mechanism. A Great War anti-aircraft weapon re-issued to steam gun boats and some fleet destroyers in WWII. BR 269/43 refers.
One large sheet. 10 drawings. *Vol.III. Drawn April 1979 - updated June 1994.
Shame didn't know you were coming - on Saturday, me and a friend, also interested in the First World War, were also at the Arsenal! Got plenty of photos of the 18 pounder this time, which i'll upload probably tomorrow night
