Early trials were conducted using an experimental dipping sonar called "Hot Dog", a harbour defence sonar capsule lowered over the side or rear of a stationary ship by electrical cable. The trials confirmed the possibility of achieving long detection ranges and the reduced efficacy of hull-mounted sonar against targets in the middle layer.
Loral Corporation originally developed radar and sonar systems for the US Navy. In 1959 it went public with an initial offering of 250,000 shares at $12 each. [ 3 ] Part of the proceeds from this offering were used to build a new headquarters on its 10-acre (40,000 m 2 ) site at 825 Bronx River Avenue, in the Soundview section of The Bronx ...
The AN/SQQ-89 Undersea Warfare Combat System is a naval anti-submarine warfare (ASW) system for surface warships developed by Lockheed Martin for the United States Navy. The system presents an integrated picture of the tactical situation by receiving, combining and processing active and passive sensor data from the hull-mounted array, towed ...
HELRAS or the Helicopter Long Range Active Sonar is a naval helicopter undersea sensor, a dipping sonar (a form of towed array sonar), deployed by helicopters of many naval air forces around the world to detect submarines; it is a form of geophysical MASINT.
The Lockheed Martin AN/WLD-1 RMS (Remote Minehunting System) is a remotely controlled minesweeping system to be operated by surface warships. It consists of an unmanned semisubmersible vehicle, which tows a sonar array, and control infrastructure aboard the parent ship. [1]
