Does anyone remember this operation? http://www.ibiblio.org/hyperwar/USN/rep/WDR/WDR58/WDR58-22.html#cn11 Four 7-man CO2 inflated life rafts will be furnished to each active submarine as soon as available and the hull allowance lists have been modified accordingly. Sea Fox (SS402) conducted tests which demonstrated the practicability of ejecting such rafts from torpedo tubes, using torpedo impulse air. It is expected that deaths due to exposure and drowning subsequent to reaching the surface should be reduced by successful use of these rafts in conjunction with escape operations
