In an air-delivered, ice-penetrating, acoustic communications package, means are provided to ensure that subsurface electronic components are safely deployed under the ice layer. The package comprises a shaped penetrator probe and a separable, interconnected sonobuoy system having a buoyant, signal transmitting section, a buoyant, signal converting section and subsurface signal detecting components. The subsurface components are housed within a canister extractable from the aft end of the probe and connected to the afterbody by a heavy-duty shock cord coupled with a lighter connecting cord. After ice penetration, the antenna section, afterbody and probe separate, with the antenna section and after-body remaining above the ice/water interface. The probe descends, paying out the shock cord to extract the component canister. The canister separates and the components are deployed full depth via the connecting cable.
