Yokosuka P1Y1b (銀河11乙型)
The Yokosuka P1Y1b is a Japanese bomber probably created in 1944. Two or three prototypes were created.
History
The Japanese naval command noticed that the Type 99 cannons were not very effective. During the technological exchange with Germany, the Japanese obtained MG 131 cannons (from the Me 210 A-1/2 aircraft), which were modified to work well in the tropics, this is how the Type 2 machine gun was created. In 1944, it was decided to use the Type 2 machine gun to strengthen the defense capabilities of the Yokosuka P1Y1 aircraft. The modification of the aircraft was simple and consisted in mounting a double machine gun in the rear turret. Unfortunately, it is not known when exactly this modification took place, but probably 2 or 3 prototypes were created, which went to combat units for testing. Their further fate is unknown.

Construction description
The Yokosuka P1Y1b aircraft is very similar to the P1Y1a version that is in the game. The only difference is the remote-controlled twin Type 2 machine gun in the rear gunner’s station.

Summary
The Yokosuka P1Y1b is an interesting aircraft for Japan in War Thunder. Thanks to the changed defensive armament, this aircraft will have higher survivability. This aircraft is ideal for grouping with the P1Y1 (P1Y1a) aircraft, which is already in the game. I encourage you to discuss in the comments and to share your own knowledge on this topic.
Finally, I apologize for the linguistic and logical errors because unfortunately English is not my main language and I had to use google translator.

Thank you for reading the suggestion, see you in the next one. Good luck pilots

You click at your own risk

And at the end good luck pilots, omaneko is counting on you

[jon_man1199]

Oh yes, please, take my absolute +1! I need more P1Y1s

[Noveos_Republic]

We need more P1Y

[yo_sat]

The technical sketch says “Type 3 13mm machine gun”. I believe the gun used was not the MG131 type 2, but the Browning type 3.

There is a slight difference in caliber, but note that the IJN called both Type 2 and Type 3 “13mm”.

[侍KAMIKAZE侍]

How about the night fighter version?

[PlayedStatue626-live]

+1 would be great in a folder

[Grzegames]

The Yokosuka P1Y1-S and P1Y2-S are in the pipeline. I’m making suggestions alphabetically and for now I’m stuck on M along with Mitsubishi.

[侍KAMIKAZE侍]

Daam how many are on the list yet to be suggested?

[Grzegames]

Honestly, too many. There are about ~70 or more possible aircraft suggestions for Japan alone. Plus a ton of suggestions for weapons, ground vehicles, helicopters, and profile icons.

[Savage_SRC]

+1, but I don’t really know why would you want an exact same plane in almost every metric but with different dorsal turret armament as another plane. If I was deciding how to implement it, I’d simply put it as a sort of researchable modification like it is with Ki-43 fixed armament. We have things like Ki-67 divided into two separate aircraft, but I don’t think there is point to do the same here, modification thingy would be much more helpful to save time and money, while not hurting BR placement at all (looking at Ki-67-Is).

[yo_sat]

I found material on P1Y1b.

Gun Mount Designation: Provisional Type 4 13mm Twin Upper Mount
Gun Type: Type 3 13mm Machine Gun ×2
Ammo Capacity: 250 rounds

The ammunition count for the 13mm rounds is not specified as being per gun or total.
Considering that the standard P1Y1 carries 225 rounds of 20mm ammunition, it seems reasonable to assume 250 rounds per gun (total 500 rounds).

Additionally, it is noted that a variant existed where the forward gun of this P1Y1b was replaced from a 20mm to a Type 2 13mm MG, and this was designated the P1Y1c (radar was also added).
When implementing this, it would be good to allow the choice of either the 20mm or Type 2 13mm for the forward gun.

[Grzegames]

That’s very interesting. I haven’t heard of the P1Y1c having radar. Although it’s a logical move to better avoid American aircraft and detect American ships.

[yo_sat]

I don’t know the specifics of the radar, but since the P1Y is fundamentally a bomber, I believe it’s a radar for searching for surface targets.
However, since Japanese radars in WT don’t function and are merely cosmetic (like the B6N2a or Ki-67 otsu), this one will likely be the same.

[Grzegames]

The Japanese Navy primarily used the H-6 radar, which allowed for ship detection (used, for example, in the G4M2) and aircraft detection (used, for example, in the J1N1-S or P1Y2-S). But yes, in War Thunder, Japanese radars don’t work.
