That horizontal "launch tube" with a big red star is a torpedo tube.

How about a towed sonar array?

Not without sinking. The ballast and trim tanks won't suffice to give that much up-angle; you'd need to flood some after compartments to make it happen, and that is a very bad idea, especially since you would not also be able to maintain neutral buoyancy.

Besides, why would you want to? Your missile tubes are configured for vertical launch anyway, and it's not as though you can just pop a missile out, haul it through the corridors to the forward torpedo room, stuff it in a tube there, and fire it. Every one of those things isn't a thing you can do.
