The Coast Guard, Navy and Air Force carry out search-and-rescue missions in U.S. waters. This applies to individuals lost at sea as well as downed airmen. The Coast Guard reports that 95 percent of all sea rescue missions occur less than 20 miles from the shoreline. Additionally, 90 percent of these incidents involve only rescue, without a search. This is largely due to distress beacons found on boats and planes, giving the Coast Guard a high probability of finding the person in distress in short time. A limited or nonexistent search is ideal because the less time they spend looking, the more people they can save. It's also less risky for the SAR teams and doesn't cost as much money. The 10 percent of missions that involve a search cost the Coast Guard more than $50 million each year [source: U.S. Coast Guard].
The mission of any Air/Sea Rescue (ASR) team is simple: get people out of the water before they succumb to the unforgiving sea. Helicopters fly in to drop rescue swimmers into the ocean from heights up to 60 feet, sometimes into 10-20 foot waves and shark-infested waters. The downed airman is often tangled in parachute lines or still attached to his ejection seat, struggling to stay afloat. While getting pelted with 100-knot wind from the helicopter's rotors, it's the job of the rescue swimmer not only to save the live of the survivor, but keep from being pulled under himself.
Navy and Coast Guard rescue swim training is among the most difficult in the military -- the school has a 50 percent dropout rate [source: military.com]. Potential SAR swimmers must come from the aviation side of the military and go through training specific to the helicopter they're assigned to. In addition to physical endurance training and a medical training course, students learn:
- Water deployment procedures
- Techniques for approaching, carrying and releasing a survivor
- Ways to release a survivor's equipment
- Detangling methods
- Pre-hospital life-support skills
In the next section, we'll look at the important role that combat SAR plays in modern warfare.
