Osa issue

[HammerUK9]

Hello all,

 

I was flying the Recon mission of the Georgian Oil War campaign (1.1) the other day, and engaged/was engaged by the Osa sitting behind enemy lines. It was happily shooting at us from approx. 15km away, altitude difference of maybe 100m or so, and getting rather close. Eventually it got us from 14km when I was getting in closer to attack it. Using F7, I also discovered that it was not using up its missile stock in the engagement - all 6 tubes were full. I ought to have saved a track, but didn't consider it. I recently did some tests in a mission, and discovered that it would only start firing at about 10km (50m altitude difference), and failed to hit me in a hover - missiles ran out of energy and passed below. It also used up all its missiles.

 

Any thoughts? Normally I avoid the Osas in the campaign; this one was a little too close to the required route for comfort, so it needed destroying. I haven't tried repeating the test in campaign, for obvious health reasons :D

Attack range and such is governed by which skill level it was set to in the mission editor, afaik. Also, they do have reloads. I don't remember how many reloads off the top of my head though.

Thought it might be something like that. In my tests, I had AI on average, so I tried it again on excellent, and engagement range/missile performance were identical. It also still ran out of ordnance. Personally I'm not too picky about its performance - I just avoid it in missions anyway - but I was just curious about that fact that it appeared to have an infinite number of missiles in one load, without needing to stop to reload.

Hammer, yes, it's a "feature" (bug) with many ground to air missiles; their firing distance is set to more than they can handle so if their target is not flying top speed towards them, missiles will fall short (especially Sa-11 buk) and you can easily sucker them into firing all their missiles without reaching you.

I have modified missiles_data.lua to avoid them firing too soon.

 

There is also another exploit (semi-realistic, really) with minimum height of target; if you fly low enough (not too hard) you can fly to any SAM without them firing at you.

I have modified missiles_data.lua to avoid that, too.

 

Also, Sa-9 strela has a bug;

if enemy aircraft/heli is flying below 150m, it fires all its missiles into the ground.
