Diagram 2. Part cutaway of TKMS Type 216. Note at least one Vertical Multi-Purpose Lock (VMPL) aft of the sail (for Tomahawk cruise missile vertical launch and other uses). Crew may be below 50 people, providing enough space/weight for a VMPL, within the constraints of a 4,000 ton (surfaced) design. (Diagram courtesy TKMS via news com au).
