LCS, Littoral Combat Ship Vessel

Thales has sold one Captas 4 antisubmarine sonar to the U.S. Navy to be towed behind the LCS itself, with a potential order of 25 units.
Also by placing sensors on remote vehicles, the LCS will be able to exploit concepts such as bistatic sonar.
A report by the Pentagon's director of Operational Test and Evaluation found that neither design was expected to "be survivable in a hostile combat environment" and that neither ship could withstand the Navy's full ship shock trials. The Navy has responded that the LCS is being built to a Level 1+ survivability standard and that the ships will rely on warnings from networks and the speed of the ship to avoid being hit, or if hit be able to limp to safety.
The combat abilities of the LCS were said to be "very modest" even before the cancellation of the XM501 Non-Line-of-Sight Launch System.
