The Dolphin Class advanced Swimmer Delivery Vehicle (SDV-X) was developed in the 2000s as a US export type based on the SDV Mk.VIII Mod-1 Gator Class SDV in service with the USN SEALs. Although the type is in many respects more modern than the M.VIII (and any comparative disadvantages are purely down to export restrictions), it is slightly too large for existing USN Dry Deck Shelters (DDS) the has not adopted it for its SDV replacement program. The Dolphin has however been exported in substantial numbers with Egypt reportedly receiving some 36 craft.

The Dolphin is equipped with two large liquid crystal displays with color moving maps and digital read-outs.
Construction consists of an aluminium frame with fibreglass shell. The reduction in battery size relative to the SDV Mk.VIII allows the crew to sit on top of the battery trays, freeing up space for stores and allowing up to eight passengers, twice the capacity of the original Mk.VIII. This optimizes the Dolphin for over-the-beach transport missions.
