Talk:Nakajima B5N

Discrepancies in range

All the relevant sources state that the attack on Pearl Harbour was launched at around 450km of distance, while this places the source range at the limit of the plane endurance, there's also other considerations : Take off, formation time, attack maneuvering ( They had to make 3 runs in some cases ) and lastly, Fuchida's own Kate loitered the battlefield for about an hour after droping its bomb. So there is an incosistency in the Source for that range...or Pearl Harbour was attacked from much closer.

Weirdness

Tried to add cruising speed to performance specifications, can't get it to show up.

Manufacturer ?

I think the aircraft's manufacturer is Nakajima, and not Mitsubishi as stated in "Aircraft Infobox". Dieu2005 06:24, 17 August 2007 (UTC)

WikiProject class rating

This article was automatically assessed because at least one article was rated and this bot brought all the other ratings up to at least that level. BetacommandBot 10:23, 27 August 2007 (UTC)

Survivors?

"Altogether, around 1,150 were built; however, not a single complete example survived." Then "An original Kate is parked at the New Cumberland Airport, in New Cumberland PA."

So which is it?

Maybe they meant to say that no B5N1s survived and a B5N2 is at New Cumberland Airport?

Hp and kW

1000 hp cannot be 750 KW. One of the two is wrong ! 88.159.13.168 (talk) 16:07, 6 September 2011 (UTC)

using convert template - 1,000 horsepower (750 kW) - i.e. the number quoted, which appears correct to a couple of significant figures.Nigel Ish (talk) 16:40, 6 September 2011 (UTC)

I give up. See also Horsepower. 88.159.13.168 (talk) 16:46, 6 September 2011 (UTC)

Type 97 machine gun link is wrong.

The link to the page "Type 97 machine gun" is wrong. It appears that someone has followed my suggestion and created a page for the Type 97 aircraft machine gun (which didn't exist a month or two ago), but the link on this page still goes to the Japanese ARMY Type 97 light machine gun. The Japanese Navy and Army didn't share any weapons in WWII, and a box-fed light machine gun would have been a poor choice as a fixed machine gun in any case. Therefore I am going to change it to the correct page, if no one has any objections. Then I am going to go and check the pages for the A6M and D3A and other types and see whether anyone fixed the links on those pages, now that there IS a page on that gun. — Preceding unsigned comment added by .45Colt (talk • contribs) 19:09, 4 January 2014 (UTC)

File:Kate B5N1 Akagi dummy torpedo.jpg

Here is the actual movie's B5N launching scene. You can watch the same moment as the photo at 9:58. https://www.youtube.com/watch?v=8n5IMg5SGvI&feature=youtu.be&t=574

Comparing with the real Akagi below, you will find some differences: Akagi has pipelines on side of the island, blackboard is placed at lower-left side, and windows are at much higher position.

Here are another scene of the movie and the real Akagi. You will find that the top of the island is much different.

B5N1 engine

I notice that it states that they upgraded the N2 version to "the much more powerful 14 cylinder Sakae engine" to increase performance, but I don't see any mention in the article of what engine they were upgrading from. It seems to imply that it was a completely new type of engine, not just a more powerful version of the same engine, but I was never aware that the B5N1 used any other type of engine, or what it might have been if it did. The Kotobuki 9 cylinder? Don't think the Zuisei was around that far back but maybe. Wasn't the prototype A6M intended to use the smaller engine at first?

The B5N1 (and the prototypes) used the Nakajima Hikari - The Hikari 3 used by the B5N1 was rated at 840 horsepower (630 kW) at 3000 m compared to 970 horsepower (720 kW) for the Sakae.Nigel Ish (talk) 15:54, 10 November 2023 (UTC)
