Grom E2 model seems to be inccorrect

Machinery of War Discussion

So considering the current discourse surrounding the KH-38 missile i figured it be worth to look at the in Grom glide bomb considering it is supposed to be part of the same family of modular weapons.

Considering the Grom E1 was removed before it went to live for reasons unbeknownts to me though i suspect Gaijin didn’t wanna give people the ability to “bomb” bases from the airfield more or less i figured i’d look at the Grom E2 a bit which is still found on the SU-34 and SU-30SM.

However it seems to in game model isn’t quite correct as the in game model retains the holes at the rear from the Grom E1s rocket booster which the Grom E2 isn’t supposed to have

EDIT: i misinterpreted something i read, however the physical model of the bomb is still incorrect.

Mind you most of this came from the Rosoboronexport video advertising the Grom E2.

make a bug report?

Warhead doesn’t equate Explosive Mass, so you’d need a source that both Warheads are comprised entirely of HE.
And to me it seems accurate, it doesn’t seem to deviate from the UPAB or KAB (which it’s apparently based on, probably share a lot of components), has 100kg more TNT for 100kg more mass, and a glide kit.

i’ve seen something else that claims that the first warhead of a Grom glide bomb(found on both the E1 and E2 version) has about 250kg explosives and the second warhead found on the Grom E2 adds another 120 kilograms of explosives according to the website i found just now so that would mean in game it is still missing about 110 kilograms of explosives at minimum.

It seems the Grom E2 in game currently is just the Grom E1 without a functional rocket booster which is not the correct way to implement it, the physical model is wrong it uses the Grom E1 physical model and its warhead weight is still off.

I am unsure how accurate this website is though.

Yeah, it was this. The range was just too extreme

6

meh, i think the removal was unnessecary if people wanna gain effectively minimal points in top tier i don’t see the harm in it.

Again, Warhead Weight does not equate Explosive Mass.
The warhead of the Grom weighs 480kg with both modules, of that 480kg there’s 260kg of explosives, makes sense to me, it’s in line with other guided bombs as well so i don’t see the issue.

For reference the same site you got the info on the Grom states that the UPAB-500B has a 390kg Warhead but in game it has 185kg explosive mass.
This gives the Grom more explosive mass per warhead weight as well.

It wasnt minimal and the problem was just how one sided it was. The potential for abuse and exploitation in SB was immense. Every match would have just been Su-34s taking off, firing Grom-1s and then turning around and landing again. Already enough issues of people exploting regular glide bombs let alone glide bombs that can be dropped virtually cross map.

If you want to bomb from long range ,just use the Grom-2, they have a larger warhead anyway, so you dont need as many per target

to me it reads as the first warhead weighs 315kg with 250kg of “volume detonating equipment” which to me reads as explosives but i assume it is some direct translation from russian, then it has a second warhead with a weight of 165kg of which 120kg is explosives or “volume detonating equipment” again.

CORRECTION ON THAT: it seems that volume detonating equipment refers to a thermobaric warhead so it can either have a 315kg HE-FRAG primary warhead or a 250kg thermobaric primary warhead with either a 165kg HE-FRAG secondary warhead or 120kg thermobaric secondary warhead.

so the explosive mass might be correct but the physical model of the bomb is still incorrect.

what other pieces of kit have seems irrelevant to me.

i am gonna be honest and i forgot sim even existed since i don’t at all play it.
for ARB and GRB Grom E1 wouldn’t really be a problem i think, i can imagine it might be for sim.
shame to lose a very neat piece of kit because it might be a problem in one mode.

11

My brother, there is no warhead that consists of just pure High Explosive.
Put a report in if you think it’s that way.
And volume detonating means thermobaric, which i think isn’t modeled in war thunder but i’d imagine it would be more effective against infantry than tanks.

12

That having been said, on the dev server you had people spawning in, firing them at bases and then J-ing out in ARB and getting base kills with them. That is OP no matter what, granted, its unlikely to be a major problem on live where you had 16v16 and people probably actually going for bases, but its pretty clear Gaijin didnt want it.

13

yes i corrected myself.
either way the physical model of the bomb is still incorrect.

14

Yeah, wrong models needs to be reported.
The british Eurofighter has a guided bomb that is an entirely different weight class than the model, and it hasn’t been fixed in months(I think they fixed it actually). Maybe this will have more luck.

Even in sim a proper bomber would beat them in, if used properly however they would have given the SU-34 a decent standoff envelope. Considering how it went with other glide bombs I really dont think they would have been an issue since iirc you needed a full payload for one base. The bigger issue in my eyes was SDBs and their ability to completely choke out any SPAAs scope but thats off topic for here so im not getting into it.
