This repair apparently cannot be carried out on board, so the most reasonable thing would be to go to the nearest base to make repairs. Midway maybe? I appreciate your comments and opinions dear friends.

you are correct.
however, some repairs that are performed without ending a patrol will NOT restore equipment to working order.
the only way to know which equipment is affected is to have it happen, go to a repair base for repairs and discover that the equipment is still not usable.
for example, not long ago in TMO, we took some damage to the forward torpedo room and tubes. my valiant crew repaired the damage such that all tubes showed repaired on the status board. then we went back into attack the next ship/convoy only to find out that all six tubes were out of order. so we broke off the attack, sailed to the nearest repair base, refitted/repaired and went back into battle however none of the six tubes would operate. we had to return to base and end the patrol in order to fully repair the damages.

so, be prepared for some unexpected outcomes while you are out on patrol. is that "real" enough?
good luck! and good hunting!
