Talk:Japanese submarine I-21

Sinking
According to this she was sunk by air attack on 29 Nov. 1943, not depth-charged by a destroyer on 4 February 1944. Which is correct? Drutt (talk) 20:19, 22 June 2008 (UTC)
 * B1 type submarine also states she was sunk by air attack. Drutt (talk) 20:24, 22 June 2008 (UTC)

Sydney attack
Interesting article, including the info that this sub participated in the attack on Sydney Harbour in 1942. Do we have a naval researcher who can provide more detailed info than is provided in the attack article? Cheers Bjenks (talk) 14:39, 14 August 2010 (UTC)

Wrong photo
I have removed the infobox photo. That photo is actually of an earlier minelaying submarine renumbered from I-21 to I-121 when the new B Type submarine I-21 was built. The difference is fairly obvious because the B1 Type submarines mounted the deck gun aft and had a streamlined seaplane hangar forward of the conning tower where the older submarine carried its deck gun.Thewellman (talk) 22:14, 17 June 2012 (UTC)
