Abstract
A self-contained, expendable sea-state measuring device which deeply submed 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.
