Swordfish float conversion was available across the fleet

How many Swordfish floatplane variants were produced?

Every Swordfish was broadly convertible, though only roughly two to three dozen at a time were assigned to the dedicated catapult flights identified here.

Any Swordfish could be converted to floats through the same attachment points used for the wheeled undercarriage. That made the floatplane a configuration rather than a fundamentally different airframe. Only a limited number normally served in that role, with 701, 702, and 705 Catapult Flights providing the principal dedicated assignments. The estimate for those units is roughly two to three dozen operational float-equipped aircraft at a time. The arrangement let the navy adapt existing machines to shipborne reconnaissance without maintaining a separate design line.
