Abstract: A retractable seal replaces the existing o-ring seals on the Tomahawk Cape Launching System (CLS). An elastomeric member is shaped to fit within the existing o-ring slot on the CLS and a cylindrical ring member of shape memory alloy circumscribes the elastomeric member. Under normal operating temperatures, the shape memory alloy member has a diameter large enough to allow the elastomeric member to extend beyond the diameter of the CLS so as to form a seal against the missile tube, yet small enough to not interfere with the seal. When the shape memory alloy member is heated, it contracts to a smaller predetermined diameter, compressing the elastomeric member within the o-ring slot so as to allow the movement of the CLS into or out of the missile tube without abrading the elastomeric member.
