A towed communication buoy for towing behind a submerged submarine comprises a forebody 11 with means for attaching a towing cable 10 and having a relatively high buoyancy which can be positive or negative. Pivoted to the forebody 11 is an afterbody 12 having a buoyancy low relative to the forebody 11. The forebody 11 may be spherical or cylindrical and the afterbody made near neutral buoyancy such that it aligns with the local water flow. The buoy is preferably made of high density syntactic foam and provided with a thin layer of GRP. The buoy houses communications aerials 14 and a spooling arrangement 15 for deployment of the aerials. An elevator 17 provides hydrodynamic lift to adjust the buoyancy of the buoy.
