A self-contained, expendable sea-state measuring device which deeply submerged submarines can launch in order to determine sea surface conditions prior to a missle launch. The device comprises a multi-chambered, buoyant cylindrical metal shell which houses a sea-state measuring instrumentation package, a moment correcting counterwieght, a long data downlink with spooling means and a bouyant lifting body which “flies”the data wire away from the launch platform. The buoy is launched from the submarine via the aft signal ejector, buoyantly ascends to the surface, and then transmits sea surface information back to the submarine via the data link.

A sensing device, launched from a submarine submerged under the surface of an ocean, buoyantly ascending to said surface and floating thereon, for remotely measuring surface wave characteristics, comprising: a long cylindrical body having a forward end, an aft end, a hermeticaly sealed chamber located at the forward end thereof, a centrally located hermetically sealed intermediate chamber and an open ended chamber located at the aft end thereof, said long cylindrical body further comprising, a long cylindrical metal tube having first and second open ends and a plurality of apertures therethrough in proximity to said first tube end, a plurality of sea-water dissolvable plugs, one each corresponding to each said plurality of apertures, for sealing said apertures, a rounded metal nose plug, fixedly attached to said first open end of said tube, for sealably closing said first end, a plurality of annular stiffening rings, disposed at preselected locations along the interior surface of said tube, for providing pressure resisting reinforcement to said tube, and a circular, disk shaped metal bulkhead, fixedly attached around the periphery thereof to the interior wall of said tube at a preselected location therealong, for providing, in cooperation with said nose plug and said plurality of dissolvable plugs, said hermetically sealed forward chamber; instrumentation means, fixedly attached within said forward end chamber of said body, for responding to vertical wave produced accelerations, producing analog distance signals therefrom and converting said analog signals to digital electrical signals; motion dampening means, movably positioned within said intermediate chamber and further affixed by tether thereto, for dampening vertical and pitchwise oscillations of and providing proper orientation to said body with respect to said sea surface; intermediate spool means, slidably inserted within said body so as to contact said motion dampening means, for holding said motion dampening means within said body; lifting body means, releasably positioned in the aft end chamber of said cylindrical body in contact with said intermediate spool means for exiting said open end and lifting clear of said submearine after launch; data link means, connected to said instrumentation package, said intermediate spool means and said lifting body means, for transmitting said digital electrical signals from said instrumentation package to said submarine along said data link; and a data readout unit, located on said submarine, for receiving said digital signals and converting them into wave height information.
