Does anyone have any submarine resources...

I'd treat each major component as a "vehicle" for rolling maintenance. Every day each component gets three breakdown checks with the attendant repair checks. That's going to be tedious in actual play if you're crossing an ocean. Maybe just come up with an encounters table for open water. Some "encounters" will be maintenance checks needed on some major component.

There's not a lot of ship-to-ship action in T2K, a submarine (or other large vessel) is like a mobile home base from which to launch missions.

This, sorta...

Every system on a boat undergoes Preventative Maintenance System checks. These are done daily, weekly, monthly, quarterly, semiannually, annually for routine maintenance. Most systems also are logged every hour when in operation and most failures will not prevent the boat from operating.

MTBF is extremely high in comparison to a tank or a truck because, once underway, most of the time, systems reach a steady-state operating condition.

I would adopt a "if you shut it down and then restart it, you need to check for failure" mode of dealing with maintenance. Major systems: engine room stuff, navigation, communications, torpedo tubes, sonar, steering and diving, and bug juice dispenser. Assume the autodog is always broken.

Thanks for the correction. I think your idea for maintenance rolls makes more sense. If I were running a game with a submarine I think I'd hand wave the maintenance portion as it's either non-game busywork for the players or a game stopping problem if they lack the skills or fail enough rolls.
