Mind you, the NH90 comes in two different variants:
-the NFH (NATO Frigate Helicopter) designed for shipboard operations and SAR (it has a 360 degrees ISAR radar, ESM, decklock system, steerable nose landinggear,etc.)
-the TTH (Tactical Transport Helicopter) designed for troop transport and cargo (it has a missile launch detector, ballistic protection, rear ramp, etc.)
If you want to do a mix of ship operations and troop transport, probably a mix of NFH and TTH would be a solution...
