Bouyant Wire Antenna System - Submarine Communications
Lockheed Martin

Buoyant Wire Antenna (BWA) System
Buoyant wires are long, towed antennas that provide a submarine with the ability to communicate while remaining deeply submerged. The system consists of a buoyant wire antenna, a reeling machine which deploys, tows, and retrieves the antenna, reeling machine controls, a transmit/receive switch, and an antenna coupler. When the submarine wishes to communicate, the buoyant wire antenna is deployed via the reeling machine which can be mounted either inboard or outboard of the pressure hull. A portion of the antenna floats at or near the sea surface and receives radio signals. An antenna that allows both transmit and receive in the HF band is also available. Signals received on the Buoyant Wire Antenna are filtered and amplified in the Antenna Coupler located in the radio room. This coupler is a broadband device that provides the interface between the special antenna and the standard submarine radio receivers. Because the system is broadband, it is LINK Eleven compatible.
