Talk:Oerlikon 20 mm cannon

Not used on US vessels
I just removed the following line:
 * On United States vessels it is not used as a deck gun, instead the Bushmaster chain gun is used in its place.

I do not really understand what this says about the Oerlikon: is it used as a "not-deck" gun, or not used at all ? If it is not, this sentence is not really appropriate: we are not going to list all ships and vehicles on which this thing is not used, are we ? Rama 08:47, 20 February 2006 (UTC)

woefully lacking in detail
The "Oerlikon 20 mm gun" is/was not just one weapon but a whole family of them. I am therefore going to extend this article greatly. -- Cabalamat 21:40, 30 March 2007 (UTC)

Produced by Hudson
The Hudson Motor Car Company built large numbers of Oerlikon guns during WW2 and also was in large part responsible for the re-engineering of them for mass production. The original Swiss versions were practically hand built like fine watches, slow and expensive to produce. Contact the Hudson Essex Terraplane Historical Society for more information. http://www.hudsonclub.org/hethist/hethisthome.htm —Preceding unsigned comment added by Bizzybody (talk • contribs) 11:31, 14 December 2007 (UTC)


 * Hudson Motor Car Company produced 33,201 20mm Oerlikon guns for the US Navy from July 1941 through October 1943, when the Navy canceled the contract and transferred it to Westinghouse. Output increased every month, peaking at 2,330 in September 1943. I'd say that'd easily put Hudson among the top producers of the gun. Storied Independent Automakers: Nash, Hudson, and American Motors By Charles K. Hyde, Pages 142-143. Oerlikon production was in addition to the millions of other parts Hudson produced for the war effort. http://books.google.com/books?id=PerGbKxOPZYC&dq=hudson+oerlikon&source=gbs_navlinks_s Bizzybody (talk) 08:07, 27 May 2010 (UTC)

Cartridge/Caliber of U.S. Version
Was the U.S. version chambered for 20×110mm like the Hispano-Suiza? --UnneededAplomb (talk) 07:53, 22 June 2008 (UTC)


 * No, the Oerlikon S and the Birkigt-designed Hispano-Suiza HS.404 family shared a similar case size, 20x110, because Hispano-Suiza had produced the Oerlikon in license and the HS.7 and HS.9. But the shape of the case is subtly different, because the mechanism of the Oerlikon requires a rebated rim (20x110RB), and the Hispano operates differently. Here is a picture in which they are side by side. Mutatis Mutandis (talk) 11:12, 19 July 2009 (UTC)

Thunderbolt
some mention of the quadmount 20MM should probably be made,Brian in denver (talk) 00:56, 27 November 2008 (UTC)

API Blowback
Why is are the words "Applicaton Programming Interface" used in parens behind "API Blowback".

Excuse me but that term did not exist when the gun was created - what gives?

 * Should be Advanced Primer Ignition Blowback. Of course no relation to software development... I corrected that. Mutatis Mutandis (talk) 21:22, 31 August 2009 (UTC)

Manufacturing Problems
There were many changes made to the weapon by the Americans (and presumably the British) as the original was unsuited to mass production. This info needs to be added. See http://www.navweaps.com/Weapons/WNUS_2cm-70_mk234.htm

Added link to Reinhold Becker (Industrialist) in German Language Wikipedia
Added link to German Wikipedia as there's no reference to the industrialist Reinhold Becker in the English version. Is this OK? I found the automatic translation to English to be quite good. Muriot (talk) 21:30, 31 October 2018 (UTC)
