The present invention is a dispenser mounted on the aft section of a torpedo for deploying an elongated, flexible article along a deployment axis. There is a molded elastomeric encasement over the exterior perimeter of the outer weldment of the dispenser for providing shock, impact, and force protection to the dispenser. A metal stiffener plate is secured to the top portion of the encasement for distributing localized compressive loads on weak sections of the dispenser. The encasement together with the stiffener plate enlarges the dispenser to approximately the same outer diameter as the torpedo to which it is attached. The encasement incorporates a fore and aft groove at a lower position with small notches for positioning and anchoring a torpedo power cable. The encasement further incorporates a pivoting retention door assembly for restraining the torpedo power cable within the groove in the encasement.
