This picture pretty much sums up this game. Several different hulls to put weapons on, varying degrees of armor, things like mines, radar, energy shields, lasers, autocannons, railguns, missile batteries...
It gives you a period of time in which to plan out your tactics, then executes them for 10 seconds. It then gives you another period of time in which to revise your orders as new information comes to light (for example, there's a giant enemy ship bearing down on your tiny destroyer), and so on.
Also multiplayer, with up to 4 fleets in two teams.
