Design
Designed by the Commanding Officer of SOE's Inter Services Research Bureau (ISRB), Lt Col. John Dolphin as a method of delivering a large explosive charge below an enemy ship, the Welman was a submersible craft 20 feet 6 inches (6.25 m) in length (including explosive charge), weighing about 2,000 pounds (910 kg). Unlike the "Chariot" human torpedo, the operator was enclosed within the craft, and did not need to wear diving gear. The Welman could transport a 425 pounds (193 kg) time-fuzed explosive charge of Torpex, which was intended to be magnetically attached to a target's hull. Vision was through armoured glass segments in the small conning tower, and no periscope was fitted.
