Navy developing next generation Submarine Monitoring Network technologies for Antisubmarine warfare (ASW)

Anti-submarine warfare (ASW) has always been a game of hide and seek, with adversarial states looking to adopt and deploy emerging technologies in submarine stealth or detection to give them the strategic edge. The advantage has shifted back and forth, but, on the whole, it has proved easier to hide a submarine than find one: the oceans are wide, deep, dark, noisy, irregular and cluttered. Sonar detection is one of the most important techniques for the detection of overwater and underwater vessels. But with the development of noise reduction and stealth material, the overall noise of some advanced warships is close to ocean background noise level, resulting in traditional sonar detection ability of this kind of “quiet” type ship have been on the verge of the limit.
