Abstract

An air-launched sonobuoy, particularly useful for under-ice surveillance, rries a descent-retardation parachute whose lanyards activate a surface float during descent. Upon impact into an ice region, a slip-rod is jarred loose from the cannister top thus freeing the surface float, and its RF antenna, to remain above the ice while the remainder of the components deploy.
