Hmm I have an idea...
Name: Mule
Velocity: Low-Med depending on payload and current ship status
Acceleration: Low
Turning rate: Med/High Precision
Primary weapon: Forward laser array
Secondary weapon/ability: Automated drones specialized in resource recovery "Mining/scavenging/etc"
Special Ability: Automated hull repair at a slow rate once hull hits 20%
Recharge rate: Average / slow upon activation of above HoT
Typical mule ship utilized for space mining / emergency repairs with prefered battle tactic of hiding in a debris field & reflecting it's forward laser array off of floating debris to attack from unclaimed materials when possible. When said tactic is impossible appearing from behind an asteroid or from the tail of a comet and firing the laser array at the broadside of a ship when possible.
Ship Pros:
Powerful forward array of lasers primarily used for obliterating asteroids for materials
Increased resource unit recovery after battle
Automated repair over time at the cost of power for the abilities
Can be used to repair fleet minor hull damage at the cost of RU outside of battle
Can assist the lander with mining under certain conditions
Ship Cons:
Slow fire rate with diminished damage output during repair times
Can only fire it's primary weapon in a forward motion with limited range
Raises likeliness of pirate raids outside of protected solar systems --
this would be pretty cool, somewhat like a random encounter by the Slylandro probes
Slows entire fleet movement speed during hull repair operations
Unable to build new ships or repair major hull damage -- Maybe something like more than 30% hull damage of a ship couldn't be repaired while in transit
Ship repair rates 1/20-1/10 the speed of space dock repairs
