The USS Balao (SS-285) plays the part of submarine that has had a fire aboard and is now stuck on the sea floor. Some trapped crew members make individual emergency buoyant ascents via the escape trunk. In the meantime, the submarine rescue ship USS Skylark (ASR-20), rushes to the scene and uses its Rescue Bell (RC14) to evacuate the remainder of the crew. This film details the U.S. Navy’s procedures for escaping from a disabled submarine, focusing on two main methods: buoyant ascent and rescue via a submarine rescue vessel (ASR). It emphasizes that while submarine casualties are rare, preparedness is critical. The senior person in a compartment takes charge during emergencies, assessing air supply and organizing crew actions. If immediate escape is required, crew members use the buoyant ascent method by equalizing pressure, inflating life jackets, and exhaling steadily while ascending to avoid lung over-expansion. Detailed steps are shown for preparing escape trunks and performing the ascent in teams. When conditions allow for rescue by ASR, a rescue bell is deployed, sealed to the submarine hatch, and used to extract trapped personnel safely in multiple trips. Throughout, the film underscores calmness, communication, and strict adherence to procedure as key to survival. 0:00 – The Navy emphasizes the increasing importance of submarines and the safety of their crews. 1:11 – While submarine casualties are rare, emergencies can occur that require crew escape procedures. 2:01 – Overview of escape methods: buoyant ascent or rescue via submarine rescue vessel. 2:13 – In emergencies, the senior man in the compartment takes charge, assesses habitability, and directs survival actions. 2:55 – Conservation measures: no smoking, spread CO₂ absorbents (lithium hydroxide), use oxygen cylinders as needed. 3:33 – Activate emergency lights and communication tools. Use radios, flares, and hammering if needed for contact. 5:01 – If one compartment is compromised (e.g., smoke/fumes), individual escapes may be necessary. 6:00 – Instructions for buoyant ascent: equalize pressure, inflate life jacket, blow steadily during ascent. 7:00 – Prepare life jackets and nose clips. Test and set relief valves to proper pressure (2 lb and 6 lb). 8:32 – Escape trunk preparation: check lights, communication, vent/flood valves, and pressurize trunk. 10:06 – First escape team enters; deep breath, strong blow during ascent; arms overhead to protect head. 11:01 – Trunk is ventilated, flooded, and pressurized to sea pressure before each escape. 12:20 – Ascent procedure: nose clip, inflate jacket, steady blow, guide yourself upward. 13:06 – Group ascends together; last man informs team leader before escaping; trunk is drained after. 14:43 – Second team performs same steps; cycle is repeated until all escapees reach surface. 16:45 – On the surface: regroup, stay warm and protected, await rescue. 17:17 – Rescue vessels (ASRs) are kept in a constant state of readiness for submarine emergencies. 18:10 – Aircraft may assist in spotting survivors; ASR looks for signs of the submarine. 19:01 – Submarine releases messenger buoy to signal position; crew reports internal conditions. 20:09 – ASR hoists buoy, attaches downhaul cable, prepares for rescue Bell deployment. 21:01 – Rescue Bell lowered, guided to submarine hatch, and sealed watertight via sea pressure. 22:02 – Bell crew opens submarine hatch and begins extraction of crew members. 22:33 – Interior is ventilated; weight is adjusted to accommodate evacuees in Bell. 23:05 – Rescue Bell ascends; process is repeated until all personnel are recovered. 24:05 – Rescue completed successfully; all crew members accounted for with no casualties. 24:26 – Final advice: know your submarine’s escape bill and procedures. 25:03 – Buoyant ascent refresher: equalize trunk pressure, inflate jacket, blow during ascent. 25:43 – Closing: Though rare, knowing and practicing these escape methods can save lives.
