Are there any concepts for that? The threads about transport submarines made me think.
Imagine a mid sized submarine which is two pressure hulls, say 40m long (so overall length about 50-60m). They are widely spaced so that additional mission modules can be dropped into the middle. Connection sections would be needed, and swapping modules would take days or weeks but could be done without dry docks. With modern electro-optical masts the sail could also be part of the module system.
Modules would include torpedo rooms (with or without reloads depending on configuration), VLS, accommodation, masts, bouys, lock out chambers, dry deck shelters, wet storage, dry storage, towed arrays, larger sonars, and blank sections. Modules would be largely self contained including bouyancy considerations etc.
Main hulls would include sonar (modest, conformal arrays?) , comms, command, crew accommodation, messes, galley, batteries, propulsion (twin screw I'd assume, like Typhoon). Control and buoyancy and trim needs (supplemented in modular fit if necessary). I'D also add thrusters and wheels. But no masts or weapons.
Am I mad or dumb?
