Speed Bump Theory

[Alneyan]

It is fully possible to do multiple battles in a single turn, both in Tactical and Simultaneous movement. This fleet will destroy every satellite it encounters and will proceed, unless a single ship is crippled and has a reduced speed. For example, if after a battle one of your escorts is reduced to a speed of 0 or 1, your hundred dreadnoughts will travel at the same speed, thus allowing you to gain some time.

So you might want to consider something like Ionic Dispersers to destroy engines, or another way to do some damage, to slow them down. That, or closing the wormhole if applicable. (Unlikely as you didn't mention Stellar Manipulation) Alternatively, you might want to try to take down the vital support ships, such as minesweepers, repair ships or supply ships, if you have the means to do so.
