This bridge had angled sides and raked windows, to allow good all-round vision and cut down on internal reflections at night. A completely new suite of armaments and electronics was added, befitting their role as fast anti-submarine frigates. The principal anti-submarine armament was a pair of Mark 10 Limbo anti-submarine
During World War II, naval personnel stationed at Point Sur, California conducted experiments with early sonar and radar systems. In 1949, while conducting research into the use of sound to detect submarines, the U.S. Naval Research Laboratory reported it was able to detect submarines at ranges of 10 to 15 nautical miles (19 to 28 km; 12 to 17 mi) using SOFAR hydrophones off Point Sur.
Submarine detection systems are an aspect of antisubmarine warfare. They are of particular importance in nuclear deterrence , as they directly undermine one of the three arms of the nuclear triad by making counter-force attacks on submarines possible.
Initially the SURTASS system were passive, receiving only sonar systems. The array was towed miles behind the ships and were designed for long range detection of submarines. As the passive systems were being deployed, an active adjunct known as the SURTASS Low Frequency Active (LFA) systems was designed for long range detection.
SMCS-NG was created as a port to Microsoft Windows of the SMCS infrastructure and applications, a move which some commentators have termed "Windows for Warships". The UK's Defence Ministry later gave assurances, through questions in the UK parliament, [10] [11] that this is a low risk use of Microsoft Windows. However, some other suppliers have ...
Autolycus or Sniffer [1] was a submarine detection system designed to detect diesel-engined submarines from aircraft. [2] It was designed to detect exhaust fumes from their diesel engines . [ 3 ] Named after the mythical Greek, Autolycus , who took part in the search for the Golden Fleece , it was developed by the British during the early Cold ...
The ACTUV is aimed at improving the ability to detect and engage diesel-electric submarines, which are inexpensive and quieter in comparison to nuclear-powered submarines, and to negate the threat of adversaries building large numbers by creating anti-submarine tactics at one-tenth the cost of building a diesel submarine.
Submarine navigation underwater requires special skills and technologies not needed by surface ships. The challenges of underwater navigation have become more important as submarines spend more time underwater, travelling greater distances and at higher speed.
