Under stealth mode (at least at western TASs) you'll have about 10 seconds to figure out who should zig and who should zag - assuming the alarm happens at max stealth range, rather than because somebody you never saw coming made a turn in your direction.

25 seconds. Stealth mode doesn't reduce the range at which the anti-collision alerts happen. What appears to be true is that you won't see the targets on tactical display until the warning happens.
