Yes, it's true, wildcats are a bit annoying , well that's the life of a bomber pilot .

[Epervier]

Bombs are nice but as a B5N2 driver, I miss forward-firing 2x7.62 mm the most. To punish those Wildcats that harass me after the successful torpedo run.

A number of B5N1s were equipped with 2 × 7.7 Type 97 machine guns in the wings.

Exactly. That's why I miss them.
Anyway, it's fun to fool around with a lonely AI fighter at a low altitude and "persuade" it to meet the ground. The agility of B5N/B6N is superb.

Can be done, copy.

At this I'm clueless:

B5N2 forward-firing 2x7.62 mm

Please a bit more precise, I'm not gonna dive into Research.
Cowl or Wings?
What Type of Weapon is that?

I found this text on this page:

https://www.pearlharboraviationmuseum.org/blog/nakajima-b5n2/

This would suggest that only B5N1s were equipped with forward-firing guns,
but maybe someone has a better source :

Given the Kate’s limited engine power, Nakajima could not add armor to the Kate because this would seriously degrade speed. The need to carry enough gasoline to meet range requirements, in turn, precluded self-sealing fuel tanks. Their thick rubber bladders reduced fuel volume too much. (When the Kate’s successor, the Tenzan, used self-sealing fuel tanks in a prototype, fuel capacity was reduced by 30 percent [Francillon 1995 431].) Although the Kate was rightly called the best torpedo bomber in the world at the start of the war in the Pacific, it was a slugger with a glass jaw.

If fighter support was not present, a flight of Kates was easy prey for enemy fighters. Coming in from the front, a fighter could attack with impunity because B5Ns had no forward-firing machine guns. One Type 97 pilot who faced a head-on fighter attack reported that Wildcat fighters attacking from the front destroyed his nine-ship hikōtai completely, its pilots being unable to do anything but try to ram the attackers [Mori 3549]. Even attacks from the rear only faced a single 7.7 mm (.303-caliber) Type 92 machine gun. Even several Type 97 flying in close formation posed limited risk to attacking fighters.

My mistake, 7.7 mm, of course.
It was not a request for a mod but just my "thinking aloud". No need to dive in, forget about it.

[Knochenlutscher]

Thanks a ton Friends, better than nothing,
copy, so the same 7.7mm, alright.

I have that Book on an old HDD, but the documents are numerical after a HD crash, so might take a while searching.

[Piotrek1]

Hi Tobias, good shot, haven't seen this picture before, will you try to implement this bomb layout into B5N1?

Best Regards,

I did make a B5N2 with 2x7.7mm nose guns in old MScfs2    but the B5N2 nose 2x7.7mm seems to be a myth created by US TAIC incorrect assessment, that was continually copied post 1945 by English language publications.   There is no photos of nose guns or cowl holes in any B5N2 pictures, or mention of them in Japanese publications. 

The first 70 B6N1/Tenzan had a single 7.7 in port wing.

This would suggest that only B5N1s were equipped with forward-firing guns,

Not sure, but B6N1 may be where the above idea came from?

The mixed B5N loads like ?x60 + 1X250 are doable, this load seems to be for attacking airfield or land targets.
...usually.....The B5N1 had two side-by-side 1x3 racks for 6 small bombs, these were seperate bomb mounts attached to a rail. 
the later B5N2 had three lengthways 2x1 racks for 6 small bombs, which were a more integrated bomb mounts....usually...

There were basically 3 weapon centrelines,
1)central fuselage (3x60kg)
1)starboard half of fuselage  (1xtorpedo, 1x800kg bomb, 1x250kg, 3x60kg)
3) starboard wing behind wheel well (1x250kg or 1x60)

Maru Mechanic lists 7x60kg were possible, and

kodochoshos that showed B5N2's loaded with 7 X 60kg bombs on missions in early 1942 when kido butai went south to the New Guinea area.

but the 3x250kg many sites lists does not appear possible to fit with early war mounts.

Hi taly01,
what i wrote was based on what i found on this site:

https://naval-encyclopedia.com/naval-aviation/ww2/japan/nakajima-b5n.php

« Reply #3 pair of quotes in green,

and here « Reply #16 :

Here is what I have used for B5N2 heavy single bomb to save others time in decoding CF_D0.msh, also 6x30/60 had minor changes. I also replaced the 3x100 (sic) with 2x250, and used the JA 800kg bomb rather than the JA 600kg clown bomb.

I need to write a cod File, adapt Slot class.
Also I might need to tweak these Hooks.
I only see this, when I have a cod file, what structure it uses.
Remember even the B5N1 Mod is in good condition, it's cod conversion not to be underestimated.

Please a bit patience Gentlemen. We are at it, it's not forgotten.

2 × 7.7 Type 97
Question how many rounds they had?
