Repair Corvette is capable of repairing and refueling
Fighters "in the field." While equipped with only
a small gun, the Repair Corvette has heavy armor to protect
itself and the craft it's repairing. Timely support from a
Repair Corvette can be quite useful in a long battle.
Repair Corvette can also repair larger ships with the ol'
"magic beam." That is the Repair Corvette's main
utlilty, since Support Frigates are available at about the
same time, and waiting for fighters to queue up one at a
time to be serviced by a Repair Corvette is impractical.
