British doctrine allows a Merlin to range out and prosecute a submarine independently when needed. A more integrated approach keeps the helicopter closely tied to the surface ship's anti-submarine picture. Type 26 could combine long-range helicopter reach with drones that help the frigate defend its own sector. The aircraft comparison reflects different operating concepts rather than one universally superior helicopter.

The Merlin and Canadian helicopter discussion illustrates a distinction between long-range independent prosecution and an aircraft working closely with the ship's own sensors and drones.
