Requirements for a modern Swordfish successor

What specifications would the Royal Navy want in a Swordfish II?

For strike work it should carry a useful load at high speed, reduce detectability, and ideally be optionally crewed.

The mission comes first when defining a Swordfish successor. For a strike role, the aircraft would need useful payload, high speed, and low observability rather than the physical form of the original Swordfish. Optional crewing could allow it to operate with or without people aboard. The name "Swordfish II" would describe flexible carrier utility, not nostalgia for a biplane. Fleet tasks should determine the specification before the navy chooses a platform.
