Laser links are fast. A digitally signed message can be extremely small. Suppose the message is 2048 bits with 128 bytes of payload (my cords, relative target coords, your coords, confidence for each number, class of target). It has been signed with a 1024 bit private key, and apparently minimum message lengths are similar to the key length.
The Wikipedia article on free space laser comms has a 1 gigabit system in the article picture, though in theory laser comms work just as fast as fiber optic, minus losses due to noise.

Anyways that would be 2 milliseconds.
How fast is the missile traveling?
