Abstract : A self-contained, expendable sea-state measuring device which deeply submerged submarines can launch in order to determine sea surface conditions prior to a missile launch. The device comprises a multi-chambered, buoyant cylindrical metal shell which houses a sea-state measuring instrumentation package, a moment correcting counterweight, a long data downlink with spooling means and a buoyant 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. (FR)
