Japanese Weapons Master Thread

I think they may just add these as suggestions. I remember seeing the BTT being mentioned as a suggestion in a different report about the maneuverability.

Dual imaging IR+UV seekers aren’t in the game yet and currently the Type 91 and Type 81C are both suffering from this issue as well where they both are forced to lock in either.

The irccm type will need a more specific source that does say how it works because as it stands there’s the fov gate and shutoff atm both of which are okay for now but we need more types added first as well.

The only realistic upgrade we can see imo is the high offbore capability but we need very conclusive/undeniable evidence for the gimbal limits

I mean, with the way IR+UV seekers are currently modeled in the game, like on the Stinger, it’s quite possible they could just change the IRCCM to work the same way as the IRCCM works on the stinger, being FOV gating + shutoff.

I saw a picture of the Type 81(C) with an armoured cabin but never managed to find it again.
Does someone here by chance have it?

Is it this by any chance?

I don’t entirely recall what it looked like, but any such images are nice!
Trying to show a Japanese fan friend of mine that the Japanese have some light armour as an option :D

Type 91 and Type 81C are not using IR+UV, the second homing mechanism is visible spectrum image homing. The secondary UV channel for IR+UV is a secondary discrimination channel, as it looks for a difference in the background UV of the sky; a decreased radiosity in the UV spectrum would indicate the presence of an object, thus, looking for the UV “shadow” of the target.

Image homing/photocontrast as we see on Type 91 and Type 81C are strictly visible spectrum, using a Si CCD and image recognition software to distinguish the target shape. Consequently, the missile can operate either in an IR or visible band image mode.

oh hello there, speaking of CCD what are they actually doing, incase of the locking for the missile
because right now type 81 nad 93 is practiacally the same as strela in visible light locking mode.

I’m not certain what specific technology Strela uses, but photocontrast/image homing are both in the visible spectrum as far as I am aware, and given that Strela’s photocontrast mode has less range than the Type 81 and Type 91 in-game, I would assume they are more or less just emulating the generational gap between the systems.

so i guess CCD is just another way of lock for the missile huh?
i was hoping the type 81 and 93 having CCD and newer stuff is making the ground/back-ground interference not a thing or just ignore them, they are really annoying thing to deal with.

The ground interference right now comes from them being modelled as contrast seekers, and the contrast naturally being lower near the ground when compared to in front of the blue sky.

An imaging seeker would track the initially locked image, therefore be less reliant on contrast making it much harder for the target to “blend in” with the surroundings and fool the seeker. I don’t think it’d completely ignore any interference, but it’d be able to distinguish the targets image even in lower contrast situations than the purely conrast tracking seeker.

yeah, the visible band image homing is a separate mode, unlike in IR+UV, where the UV channel is a secondary discrimination channel in use in tandem with the IR homing to help reject IR signatures which do not sufficiently decrease the background UV radiosity.

There are probably some advantages to resolution and consequent target discrimination for the Type 81/91 against the Strela, but it’s in all likelihood effectively emulated via the range of acquisition difference, which is already present in-game. What other characteristics there may be would require more precise information regarding the differences in their systems.

Excuse for off-topic. Have not found the main aviation topic.
There is some information about Japanese engine fire extinguisher.

A7M.
Probably it has engine fire extinguisher because there is 2 extinguishers. Automatic and manual one. All previous planes use only manual extinguisher for engine and automatic for fuel tanks. So, I think the manual extinguisher is for engine and automatic is for fuel tanks.

A6M2/M3
Looks like they had. In the table of difference between A6M2 and A6M3, there is no any mention of fire extinguisher. But in table of A6M3 and A6M5 there is the mention that engine fire extinguisher was removed but fuel one added. So A6M3 and A6M2 could have engine fire extinguisher

Probably, somebody else have information about Japanese engine (it is important because there is no fuel tank fire extinguisher in game) fire extinguisher on other planes from books or manuals?

Thinking to add the same table with fuel tank fire extinguishers.
Does somebody has something about it? Maybe the information about effective of this systems?

Isn’t the A and B in AAM-5 reversed?

You may be right ill have to revise that…thanks for pointing it out ill just leave this instead

It’s not being added. Not unless Gaijin wants a mass amount of Controversy.
The only one that will possibly get a chance of being added is the 2 20mm interceptor variant, which had no warhead. Since its similar to the BI with more fuel.

Was too late in the war by then.

In this commonly shared sceenshot, the sparrow is quoted as having 32g’s per axis, with 45g’s in dual plane. However in warthunder, it only has 25g’s. Is there a particular reason for this?

Or is this just a representation of a generic normal missile.
