I'm curious what sort of ships people here create for special tasks or needs. Not like a small fighter, but something geared more towards another task.

For instance - I like to create a massive sensor ship. It's task? It sits around wherever I place it, and it has the largest sensor radius I can find on it. I put maybe one engine on it, so it can move fast, but I generally load it up with only sensors. I like having these around certain areas, so i can keep an eye out. It's the only specialized ship I really use at the moment. Other than that, it's just your basic attackers, transports, and constructors.
