A buoy (20) for providing communications between an underwater craft or installation (10) and (5) remote radio communication apparatus (40) comprises a surface module (23) comprising radio communication apparatus and a submergible module (21) comprising acoustic communication apparatus. The surface module (23) is hermetically sealed on launch to the submergible module so that the buoy ascends to the water surface under its own buoyancy when launched from the underwater craft or installation. Flotation means are deployed from the buoy at the water 10 surface. The surface module is then separated from the submergible module at least partially to flood the submergible module to cause the submergible module to become negatively buoyant and to descend to a predetermined depth on an umbilical communication cable mechanically and operably linking the surface module to the submergible module.
