How HMS M2 might have shaped carrier-submarine tactics

The M2 prompts a comparison of tactical underwater concealment, strategic carrier stealth, and the limited appeal of very large specialist submarines.

Question

How would HMS M2 have influenced tactics if it had succeeded as the first carrier submarine?

Short answer

It might have produced a small specialist class and new reconnaissance roles, but conventional carriers and submarines would remain more efficient for most missions.

Notes

A successful aircraft-carrying submarine could have encouraged limited imitation, much as cruiser submarines attracted interest without displacing conventional boats. Its chief advantage would be tactical concealment, but a fleet carrier offered much more aviation capability and could achieve strategic uncertainty through varied operations. The panel also explores how German interservice competition would have complicated aircraft allocation and how such boats might have supported U-boat reconnaissance or wolf-pack operations.
