Multiple Problems
I've fixed the reference to 'Bofors 130' rather than 40mm Bofors, but this needs attention from someone with better knowledge of WWII US AAA than I have:

1) Needs a clearer description of the prevalence of M45s in US AAA units, beyond 40mm Bofors there should certainly be reference to 37mm M1/M15 and 90mm M1 weapons.

2) Needs to talk about use in the Pacific and in the Korean War, and possibly elsewhere with other nations.

3) Probably should link to the Israeli use of refurbished M45s as the 20mm TCM mount.

4) The concentration on Oppenheim is questionable, the M45 may have played a significant role, but it is extremely unlikely it was responsible for all the aircraft downed when the entire Corps AAA Group was defending the bridgehead and heavier, director-controlled, weapons would have been more effective against night or higher altitude attackers. Equally the significance of the crossings is probably over-played in comparison to the major Allied Rhine crossings as part of Operation Varsity and the equally famous 'Bridge at Remagen'.

5) There's a breathless gee-whizz quality to the writing that doesn't really suit.

The math
this thing must have been impossible to feed. if the ammo cans only held 200 rounds and the rate of fire on a .50 is 500 rounds a minute. yould have to reload every 30 seconds or so.Brian in denver (talk) 19:25, 29 November 2008 (UTC)

Its probably safe to assume that it was fired in short bursts, any sustained fire would possibly result in overheating 125.238.22.251 (talk) 05:09, 10 June 2009 (UTC)


 * This claim is obviously wrong. If an 89lb can only held 200 rounds, each round would weigh over 7oz (almost 1/2 lb or over 450g per round, for those keeping score at home)! Granted, a fraction of that would be the weight of the can itself rather than its contents, but this claim clearly doesn't track. Lexington50 (talk) 05:44, 4 July 2013 (UTC)
 * World war 2 era 0.50 cal API-T apparently weighed 610 grains (39 grams). Somebody probably misread grain (gr) as gram (g). Hotchkisses25 (talk) 08:30, 20 February 2024 (UTC)

The cost
At $400 to $605 per 100 rounds... That's $8,000 to $12,100 per minute of firing a M45 if the rate is set to 500 rounds per minute of firing time on each gun. Prices from http://www.aaa-ammo.com/bmg.htm Private owners of the M45 (there are a few) need very deep pockets to play with their toys. "It's only $4 a round." Yeah, only $4.00 2,000 times per minute. $133.33 per second. Bizzybody (talk) 05:45, 14 January 2011 (UTC)

RNoAF
It was in use with the RNoAF (Royal Norwegian Air Force) at least as late as the mid-90's. AA units were of two types, L40 Bofors batteries and NOAH (HAWK) batteries. Each platoon had a nominal strength of 2x L40's OR 3x HAWK launchers PLUS 4x quadmounts. In practice 2 or 3 quadmounts were operational. 91.186.68.96 (talk) 09:34, 13 February 2015 (UTC)
