location of small SOFAR devices detonating at predetermined depths underwater. SOFAR nets are effective only in ocean depths greater than the continental shelves (600 ft). Land masses, including underwater sea mounts, will block the SOFAR sound signals. a. SOFAR devices may be released by aircraft, vessels, or boats experiencing difficulties, or by survivors adrift on the ocean; if time does not permit release before the distressed craft ditches or sinks, a device may automatically arm itself at approximately 800 feet and detonate between 2,400 and 4,000 feet. One station can obtain a line of position (LOP) and an approximate range on each signal. Two stations can cross LOPs to obtain a fix with an accuracy of approximately 2 miles. b. SMCs can query the SOFAR net any time a craft known to carry a SOFAR device is missing. If a craft is definitely overdue, the SOFAR net can search its recordings for SOFAR signals from the last contact with the distressed craft to the present, since survivors may have SOFAR devices in rafts as well as in their vessel. c. SAR aircraft carrying SOFAR devices can use them in conjunction with SOFAR stations to maintain a constant bearing with a distressed craft. When a SAR aircraft arrives on scene, the SOFAR net may be able to vector it directly to the SOFAR datum. The SAR aircraft may also be able to release a SOFAR device at a distress scene where a lack of navigational aids prevents accurately fixing the distress position. 8. The High-Frequency Direction-Finding (HFDF) net has a frequency range between 2000 kHz and 30,000 kHz, and covers both the Atlantic and the Pacific oceans. This net is alerted when there is a reasonable expectation of locating the distressed craft. To alert, SMCs provide certain information, outlined by Navy OPNAVINST C2520.1 series and Coast Guard COMDTINST 2-13

3130.16 series. The SMC should de-alert the net as soon as possible after the distressed craft is located. 9. Recording Radar Systems. a. USN Fleet Area Control and Surveillance Facility (FACSFAC). The U.S. Navy operates FACSFAC facilities at Oceana, VA, Jacksonville, FL, San Diego, CA, and Honolulu, HI. These facilities utilize both long and short range radars in support of the Navy's offshore surveillance requirements for aircraft operating in coastal warning areas. These facilities generally provide radar coverage from the shorline, out to sea. FACSFAC facilities record primary and secondary radar data shich is retained for a period of 15 days. Data can be rapidly extracted via a visual playback of the recording medium while also producing a hard copy of the playback. b. TPX-42(DAIR) Terminal ATC Radar Systems. USN and Marine Corps Air Stations record terminal ATC radar data via the TPX-42(DAIR) recorder. Data from these systems are limited to secondary radar only to a maximum range of 60 nautical miles. Recorded data is retained for 15 days and can be rapidly extracted via a playback of the recording medium. D. The Army, the designated SAR Coordinator for military operations responding to natural disasters within United States territory, maintains a large variety of resources, including a large number of helicopters, light aircraft, ground vehicles, and surface detection nets. Primary resources are described below. 1. Aircraft, either helicopters or light fixed-wing, are excellent search aircraft. Some helicopters do not have hoisting capability, and must land or hover just off the terrain to retrieve survivors, or use alternative devices. Some aircraft have SLAR and other sensors for electronic and radar searches. Pilots are experienced in low-level flying and highly trained in visually detecting search targets. Aircraft are usually restricted to operations over land. 2. Land SRUs are numerous, and vary widely. Many personnel are trained in land search operations, providing an excellent source of SRUs for incidents requiring large numbers of personnel and equipment. 3. Disaster equipment includes portable hospitals that can be transported by truck or airlifted. Stocks of cots, food, medicines, and other equipment exist to meet the Army mission of disaster assistance. Equipment may be issued directly at disaster sites or to the American National Red Cross. E. The Federal Aviation Administration (FAA), in addition to other resources, maintains a nationwide communications net, coordinated with international aeronautical communications services for the control,
