Dedicated anti-missile platforms! I think they are immobile. Any suggestions how to penetrate their AMM shield? Their missile speed is 47k mein 49k but tha is not enough.
One method is to use time-on-target salvos. Build a few different types of missiles, with different speeds. If your fastest missile is 49k, you could also build 43k and 37k missiles. Then sit at a safe distance, and calculate the run-time for each type of missile to enter the enemy PD range.
If you are 60 m-km away, for example, the 49k missiles will require 1224 seconds to run in, the 43k missiles will require an extra 171 seconds, and the 37k missiles will require that plus a further 226 seconds. So you could launch the slowest missile version for 226 seconds, then switch to the second-slowest missile version for another 171 seconds, then switch to the fastest missile version for another 200 seconds or so. The salvos will start out spread out in a line almost ten minutes long, but the faster ones... launched later... will catch up to the slower ones and all of the salvos should enter the enemy's PD range just about simultaneously, presenting him with three times as many targets at once.
Naturally, this works best if your Task Group has been trained up to 100% Task Group Training, so that you don't have to factor in (and guess at) any orders fire delay.
You should focus on getting the maximum number of salvos on target at once, rather than the maximum number of missiles... since each defensive PD fire control can only target one salvo (and all of the missiles in it) on each five-second impulse.
