Does anyone have any submarine resources for any of the submarines?

There are a lot of very knowledgeable people here who'd be happy to help. Can you be a little bit more specific with what kind of resources you're looking for?

I'm looking for different crew strength, rough idea of layout.... and what(if any) marine contingent (or countries equivalent) they would have. Attack sub or missile boats... Deck composition (what is on what level) etc. There are sadly no stats for any of it for the game. I want to use it as a plot point/rogue element and want a bit of realism...

Do you have access to the T2k v1 adventure module, Mediterranean Cruise? It has info about the Los Angeles Class SSN, USS City of Corpus Christi, including internal layout, crew, armament, ect.

Since the module authors probably didn't have access to as much information as the present-day internet user, I'd definitely Google Los Angeles Class Submarine and double check their stats.

Here's a link to a cutaway infographic of an LA Class attack sub.

The Internet Archive has tons of books on submarines with lots of information.

how could it be converted to TW2K? what are the maintenance hours for a diesel sub vs a nuclear? What would its range be? a modern Nuclear sub (US) has ships stores for about 3 months...reactor for about 15-20 year... I can get a rough idea from Janes guids...but crunch number for the game. ?

The T2K maintenance hours don't really work for large vessels like a ship or submarine. Unlike a truck or tank they don't pull over to get repaired, they're under constant maintenance by the crew. So the maintenance number isn't germane unless you've got less than the minimum crew.

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.
