Mission modules could separate Merlin upgrades from airframes

The proposed rear-ramp container system returns during the discussion of modern multi-role logistics aircraft. An airborne-warning or anti-submarine module could be rolled into a common Merlin airframe and connected through standardized openings and interfaces. Separating mission equipment from the helicopter would make it easier to repair or update sensors without rewiring every aircraft. A replacement airframe could then be designed around the same module or the module adapted to the new platform. The concept trades some higher initial airframe cost for long-term flexibility in upgrades, maintenance, and fleet assignment.
