Talk:M4 autocannon

message: Being that the T9 and M4 are different versions of the same gun, I think a merge is in order.
I added some amplifying information about usage of the 37mm cannon on board PT Boats and JFK using an M3 AT gun on his boat. I obtained this info from interviewing 12 different PT boat veterans from WW2 and restoring PT658 in Portland, OR Jerry (jngilmar)  —Preceding unsigned comment added by 134.134.139.71 (talk) 17:42, 16 November 2008 (UTC)
thread_title: Merge

message: There is a paragraph here that does not belong: "John F. Kennedy's PT-109 had a US Army M3 37mm Anti-tank Gun installed on the foredeck by removing its wheels and bolting it to a heavy timber (4 in x 4 in) which was attached to the deck. This cannon was installed only days before the mission where PT-109 was lost. In fact, the 4x4 timber was used as a float by Kennedy and crew to keep them together during their swim ashore from the stricken hull, since they had displaced their life raft to make room for the 37mm cannon."  It'd be nice to put it here, but the M3 was not the same gun.  I'm removing it and moving it to the M3 article.--Nukes4Tots (talk) 00:43, 24 February 2009 (UTC)
thread_title:  M3 and M4 

message: Okay, not entirely sure why, but the history of this autocannon is missing.  The Browning prototype was built and demonstarted in 1921 and developed into an acceptable weapon by 1928.  In 1938, it was standardized for anti-aircraft use as the M1.  The M1A2 followed and the Navy and Army Air Force adopted it for shipboard use and aircraft use respectively as the M4 cannon.  All of this is missing.  Am I missing something or is there any reason not to add this? --Nukes4Tots (talk) 00:43, 24 February 2009 (UTC)
thread_title: M1 and M1A2

message: I was wondering if the M4 was ever used by P-39 and P-63 pilots to try and destroy tanks, especially the Russians on the Eastern Front?  There were aircraft that used 37mm anti-tank guns in WWII; such as the Junkers Ju-87 Stuka G1 and G-2 and the Yak-9T.  While 37mm is not that powerful when compared to the 76mm, 88mm, and other big guns carried by WWII tanks; a 37mm could knock out a tank if it hit them in a vunerable area, i.e. fuel, turret, or the less-armored back area.204.80.61.110 (talk) 18:46, 27 February 2009 (UTC)
replies: text: Yes, in fact that was the intent.  The standard practice was to dive at the tank.  The weak top armor was no match for a round or two of 37mm.  The Russians bought the bulk of the the P-39's for exactly this reason.  It didn't even need to hit a fuel tank, just pretty much anywhere on top.  --Nukes4Tots (talk) 19:03, 27 February 2009 (UTC)
replies: text: Thank you for this information.  I think it should be added to the article. Not everyone reads the discussion page.204.80.61.110 (talk) 21:36, 27 February 2009 (UTC)
thread_title: Was it used as an [[anti-tank]] weapon?

message: Here's a reference confirming the quantity of 150 weapons, "37 mm full automatic cannon", purchased in 1921 for $300,000 by the USAAC for the purpose of large aircraft weaponry. Army appropriation bill, 1921, by Committee on Military Affairs, Subcommittee No. 1, United States, Senate. "It is estimated that these will equip the new large planes which the Air Service are expecting to build next year." Binksternet (talk) 14:19, 2 June 2009 (UTC)

thread_title:  YFM-1 Airacuda first 

message: I'm not too wikipedia savvy but if someone wants to find additional sources, there seem to be some experimental aircraft uses for the M9. In particular, the experimental P-63D-1 (production: 1) seems to have used an M9, and this one Russian webpage <http://www.airwar.ru/weapon/guns/m9.html> shows an A-20 and XA-41 as well.

thread_title:  M9 autocannon uses 

message: In the Aircobra article this is listed as an Oldsmobile T9 Cannon. Obviously someone had data stating that Oldsmobile was also a manufacturer of this weapon. It would be nice if there was a concurrance of information. 75.143.19.122 (talk) 18:18, 13 November 2021 (UTC)
