Aim-54 Battery Life

Hi, What is the current battery life in seconds for the Mk60? And the other variants?

I believe it’s around 120-130 seconds, but don’t quote me on it. I know they wanted it to be barely longer than 2 minutes

It used to be 160s, and we increased it to 240s, to be on the safe side to facilitate the known real life test shots for the Amk47 at 110nm, as it would reach the target only slightly after the 160s. For any other shot it does not matter, because the missile will bleed out energy and detonate before it reaches the end of the battery life time anyway, just as it used to (even well before the 160s). We will investigate the battery life time further though.

Mind you, the 110nm shot only works if you set up the target like a drone, and it continues flying straight into the missile. If you do not, the same applies again: your missile will bleed out and detonate before it reaches the end of the battery life time. Additionally, both the C and the mk60 were able to make the shot well within the 160s, too. So if anyone is concerned that the aim54s will now chase you for 4 minutes, it is absolutely a non-concern, as this is naturally inhibited by the missile's performance and self-destruct mechanism, which iirc kicks in when the missile's speed reaches somewhere around 200kts.

200knots indicated? tas? how does the missile know its own speed?

That's just a mechanic in DCS I suppose to "delete" missiles from the world. How it works irl, I do not know fully, it may very well know that it missed its mark by x amount of time, etc... I also do not know if it is 200 kts exactly, it is just the speed around which I observed it most. The best explanation is: when it is like really, really slow, missile go boom.

Sorry that I cannot give you a better answer, that's not defined by us.

Because it knows how fast it isn’t going!
