British Weapon Systems - Technical data and discussion

Ok interesting, from my testing with IOG + SALH at least, the IOG guidance is lost after picking up laser (and losing it), as how it works on the live server too. Code wise the GPS + SALH are the same as IOG + SALH (but instead they have 0 inertial drift), but maybe somehow for those it does switch back to IOG/GPS?

Are you sure it wasn’t just luck because the bomb was fast and managed to change course in time before turning off laser? Like how I test it is, get within 4.5km (so the bomb is in “POINT” mode) of a target above them, drop the bomb slightly off to the side with laser on, then turn off laser directly after dropping. At least with regular GBU-24, it does not go to the last known spot and just flies off in a ballistic trajectory. Could you test it again this way? It’s not as important now, but if GBU/EGBU-24 seekers could become better, it may be more significant.

Shouldn’t the GPS equipt Paveway & Paveway III variants loft at low altitudes?

Also some nice LARs / comparisons are included, which we might be able to reverse engineer.

Dare I say this… How does a bomb self-loft?

The same way the Maverick does; pre-calculated deflection of control surfaces for so many seconds post release (G-Bias, Trajectory shaping), and then maintains zero AoA until the Seeker reaches some preset look-down angle then proceeds tracking as normal.

Basically what it is doing is storing excess energy that it has at release (speed) as altitude since past the point where the required glide slope to the target can be met, it is in excess and flying a ballistic course / zero AoA course incurs greater losses to drag (scales with V^2 not ~V^6 so is much more efficient especially at very low altitudes and near transonic releases due to a number of factors) and so to best conserve that energy as it may be needed for terminal maneuvers, or converted back to velocity due to impact velocity requirements for penetration of the target.

Let me explain a thing then. The GPS guidence does not turn back on, that is true, game limitation. If you tested it on normal PW3 it does return to IOG when you turn the laser off, but it has a HUGE drift value of 5 (for example AIM-54 has 2), so it goes off course severely. EPW/PW4 have their drift set to 0, to simulate GPS turning back on, and they will not miss. In their case IOG keeps turning on and off when you play with the laser. And also there is for example Hellfire, where if you turn laser on it will disable its IOG and go dumb.

Paveway III (both normal and GPS equipped) had a bunch of different lofting modes. It’s on my list of things to report, but I need to find time to do a proper write-up on the different modes.

My current longest range shot with brimstone. When I go up to 23km it’ll still self destruct before the target

Means the time to target was over 60 seconds, same for all guided munitions in game, if the battery dies the weapon self destructs.

yeah its very annoying

Have Brimstones got faster?

That seems to be travelling a lot quicker than last time I used them, but perhaps its just as its being fired from altitude

Someone has told me from their testing on the dev server that the lock range of the PGMs and Martels has been increased a lot (up to at least 30km)

Is this an actual change or is it not true?

Martel has always been capable of 30km

I will look at it rn, but i doubt it

You beat me to it by 3s >:(
But overall does not seem like anything changed.

the issue is it had brimstone 1s that only had the LOAL mode as far as I am aware, the Dual mode brimstones were the ones that added Mode 2 that could be used like other FnF weapons in the game where they would need to lock a target before launch

Eee, no. Brim 1 had MMV seeker only. Seeker would LOAL or LOBL depending on the situation. DM Brim added laser seeker, that can be used to guide the missile, or designate a exact spot MMV has to look at.

Nope, point only

oh fair enough then, still doesnt change gaijins opinion on the weapon thinking its going to be too strong
