Abstract : The ALSS-1 sonar is a parachute deployable sonar that operates at deep refractive depths. It can be used as an expendable store by fixed or rotary wing aircraft against submarines that are operating in the quiet mode with active detection ranges and bearings out to 18 miles. Phase IIA of the program provided for design analysis of the subsurface deployment sequence with studies and tests conducted on shell deployment, azimuth rotation, telemetry wire payout, acoustical lens water inflation, and gas enablements.
