The AASM 'Hammer' - History, Design, Performance & Discussion

has anyone attempted to get the IR AASM its gnss mode since the russian get theirs on the IR 38’s?

All AASMs have GNSS in-game, but as with Kh-38MT, it doesn’t work properly.

IR GNSS does not work at all, because it will always fire in Point or Track mode

Bet they’ll bias “fix” the 38MT to have LOAL

38mt also has this problem

That isn’t really how it works. GNSS was missing from the 38s, the module is in the mid section of the weapon. All this really does is bring the guidance modes on parity with what we ought to expect (minus the IR seeker, but having tested it on dev, flankers will be using the laser one more often for the range advantage and GNSS guidance).

GNSS won’t work on 38t the same way GPS won’t work on AASM. If they fix it for one, it will be fixed for both.

With the GNSS change, these have become pretty rubbish and you’re essentially locked into the IR version if you want anything half effective. Unless you are actively guiding it, AASM will miss by margins large enough that it won’t even scratch a lightly armoured vehicle.

Which is slightly infuriating.

As you lot seem the most informed, it seems if we are to have anything done about the deviation, you’re going to have to report correct accuracy which is fun.

Wdym. Did they brake GNSS guidance this update (I haven’t really played the AASM for a while)

10m deviance. Basically makes anything >500kg explosive weight nonfunctional unless you salvo a half dozen at a target. Which you will note is incredibly less than ideal if you only have half a dozen to begin with. Trialed 8 passes in test drive, only scored 1-2 kills per pass with 6 AASM launched each pass, with 1 pass having no kills. This included being launched against hard and soft targets, soft targets often the deviation would put the weapon so far off course it just wouldn’t do anything.

Further testing leads me to assume they’ve weighted it for the outer edges, as I refuse to believe I’m this unfortunate. Having watched the impact, it seems the weapon favours the outer edge of the 10m deviance, and only on closing with the target, consistently deviates to another point tending towards the outer edge of the claimed deviance. This behaviour appears consistent. I assumed the deviation did not impact the laser guidance, but it appears to carry over to that too, but is significantly less consistently present.

Oh yeah that has to be wrong for the AASM GNSS guidance at the very least.
Could be worth a report. Probably going to be refused tho, since they don’t model specific GNSS guidance for different weaponry (or GNSS type), and probably won’t because it would not favor the Russian GLONAS since GPS (and Galileo, if used by the AASM now) have far better accuracy, in the <1m range for military applications

No worries, it’s going to be reported most probably soon I would guess. Just going to need to show that AASM uses GPS and that GPS as 1m accuracy, and that AASM (not IR) can reach that 1m accuracy

Everything I can find from a quick search actually states the GPS/INS AASM to have a CEP of 10m, while the IR one has a CEP of 1m, which is why the IR one was used for strikes requiring much higher accuracy. Its possible/likely they improved it since then, but unless someone has sources stating that explicitly, the change actually makes the AASM when using GPS only more historically accurate it seems.

The thread itself supports that actually;

Issue with it not killing stuff is likely more due to gaijins underperforming HE damage models, which effect every HE munition.

They changed it a bit after the Tusk Force update went live, the AASM Hammer doesn’t leave a smoke trail anymore

for a 10x more expensive kit to have such a garbage CEP is pretty disappointing

JDAM can do 1.7m CEP and GBU-39 sub-1m CEP

Thanks to Panda for taking this video, I can confirm that it is now low/no smoke.

They may not have (or be able to advertise for export) access to Y- or M- Code modes that improve accuracy, or it may also be referencing non-best case accuracy as even GPS isn’t constant as it depends on the relative location(s) of the visible satellites.
