  • Raytheon to supply variable depth sonar for US Navy LCS vessels 24 May 2017 The US Navy has awarded a contract to Raytheon for the delivery of its new variable depth sonar (VDS) system, which is an anti-submarine solution designed for the littoral combat ship (LCS) class.

“The VDS variable depth sonar is an active sound producing system that provides the acoustic signal that is sent out and reflected back from the target submarine. The reflected sound is received on the MFTA. The VDS and the MFTA are towed separately but they can be towed at the same depth, or at different depths.

“Raytheon’s reliable, cost-effective variable depth sonar will allow the Navy to rapidly introduce this new anti-submarine capability to meet the LCS mission.” The system is identical for both LCS variants, whose size and reduced crews demanded reduced size and weight of the VDS system to minimize ship impact and ease of operation.

Navy pursues lightweight LCS sonar, sensors. By Kris Osborn. Nov 01, 2016. The Navy is developing lighter weight anti-submarine technology designed to improve the Littoral Combat Ship’s ability to track, locate and destroy enemy submarines. The idea is to harness lighter variable depth sonar (VDS) and AN/SQR-20 Multi-Function Towed Array (MFTA) ...

(MFTA) and variable depth sonar (VDS) with the AN/ SQQ-89A(V)15 Surface Ship Undersea Warfare Combat System. MFTA and VDS provide submarine search, detection, localization, and track capability. MFTA also Activity LCS Program • The Navy scheduled the following operational testing for FY20: Independence variant with SUW MP Increment 3

The delivered sonar’s smaller,lightweight design frees up space and manpower onboard LCS ships. While traditional anti-sub sonars require multiple sailors to physically move them overboard, just a few are needed to remotely deploy and operate the single-tow VDS.

Well, as the name implies, the VDS can be raised or lowered to any desired depth, somewhat akin to a helo’s dunking sonar. This allows the sonar to listen under thermoclines. Thermoclines are temperature gradients in the ocean that form layers. The layers tend to reflect sound at the boundaries between layers.

The VDS is part of the anti-submarine warfare mission package that will be used on littoral combat ships to locate and track enemy submarines. Raytheon says this ship-deployed sonar system design, identical for both LCS variants, features reduced weight to minimize ship impact, increased maneuverability and it provides the opportunity for increased warfighting payloads.
