![]() ![]() 1 is a cutaway view in perspective of a towable communications vehicle according to the invention įIG. These and other objects, features and advantages of the present invention will be more completely understood by referring to the accompanying drawings in which like numerals indicate like parts, and in which:įIG. This detracts from the overall aim of maintaining a posture of minimum detectability during operational situations.Īccordingly, it is among the objects of the present invention to provide means providing long range, short range, and visual communications capabilities for submarines while operating at depths below surface wave effects to provide a visual and radio-type communications system for a submarine while operating at below periscope depth and at very high speeds to provide an all-weather high speed surface and subsurface towing arrangement for carrying communications equipment as part of a submarine communication system to provide a towable communications equipment-carrying vehicle capable of being towed at very high speeds over the surface of water or when submerged to provide a towable vehicle adaptable for carrying a variety of communications equipment for cooperative use with a high speed towing submarine and of a hydrodynamic configuration resulting in very low drag when towed either on the surface of water and submerged, and to provide a highly efficient hydrodynamic towing system having minimum drag at high speeds both on the surface and submerged. While it may be true that a large, high bridge fairwater confers the advantage of permitting visual sighting through a periscope while the submarine is at somewhat lower depths than those permitted with a short fairwater the fact remains that if a submarine is operating at great depth and it is desired to obtain a visual sighting, the submarine must be brought all the way up to a position relatively quite close to the surface to obtain through a wake-producing periscope these visual sightings. The provision of more control surfaces to compensate for the hydrodynamic effects of a large bridge fairwater lowers the operating efficiency of the submarine. ![]() With a large bridge fairwater, tight turns at high speeds are difficult to make as well as other concurrent maneuvers requiring use of diving planes. These large rolling moments cause changes in depth which must be compensated for by positioning the diving planes at large trim angles. It is well known, for example, that a bridge fairwater forms a large hydrofoil surface which causes rolling moments when the boat is put through a constant depth turning maneuver while submerged. Yet, in present day operational high speed submarine types, there are certain structural appendages which detract from the potential operational maneuvering capabilities of a high speed (submersible) type submarine, notably a large bridge fairwater (sometimes referred to as a "conning tower") which is used primarily for housing communications such as visual sighting devices and radar and radio antennas and periscopes and secondarily to provide a high platform for boat maneuvering and lookout purposes. Indeed, the submarine as a weapon has been greatly expanded in its utility and effectiveness. ![]() In recent years the operational capabilities of submarines have geen greatly extended so that at the present time high speed submarines with great tactical and strategic destructive capabilities may operate at great depths for extended periods of time with very little likelihood of being detected. This invention relates to a submarine communications system and more particularly relates to a communications system wherein terminal transmitting and receiving communications equipment for a submarine is positioned distantly from and operated remotely from the position of the submarine. ![]()
