Secretary of Defense Chuck Hagel has directed the Navy "to move forward with a multi-mission small surface combatant based on modified Littoral Combat Ship (LCS) hull designs."
Consistent with the Fleet's views on the most valued capabilities delivered by a small surface combatant, the modified LCS ship will be more lethal and survivable. It will provide multi-mission anti-surface warfare (SUW) and anti-submarine warfare capabilities (ASW), as well as continuous and effective air, surface and underwater self-defense. Adding to current LCS Flight 0+ baseline configurations, which include the 57mm gun and SeaRAM missile system, this ship will be equipped with over-the-horizon surface-to-surface missiles, air defense upgrades (sensors and weapons), an advanced electronic warfare system; advanced decoys; a towed array system for submarine detection and torpedo defense, two 25mm guns, an armed helicopter capable of engaging with either Hellfire missiles or MK-54 torpedoes, and an unmanned FireScout helicopter for surveillance, reconnaissance, and targeting.
Modularity design features will also be retained to augment SUW and ASW capabilities as directed by the Fleet Commanders. Available mission modules include Longbow Surface to-Surface Missiles (Hellfire), two MK46 30mm guns, and two 11M RHIBs for Surface Warfare, or a variable depth sonar for submarine warfare which, when added to the ship's organic multi-function towed array and embarked helicopter, make this an extremely effective anti-submarine warfare platform.
In addition to the improved weapon systems capabilities for this ship, which reduce its susceptibility to being hit by a threat weapon, the small surface combatant will also include improved passive measures - measures that will reduce the ship's signature against mine threats, and measures that will harden certain vital spaces and systems against potential damage caused by weapon impact - to further enhance its overall survivability.
From an operational perspective, the sum of these improvements will increase the ship's capability and availability to participate in SUW Surface Action Groups, ASW Search and Attack Units; escort of High Value Units, and support of Carrier Strike Group (CSG) SUW and ASW operations.
With increased lethality and survivability, the modified LCS will provide the flexibility to operate both independently and as a part of an aggregated force. This decision allows the Navy to add organic multi-mission capabilities to the small surface combatant force while leveraging the benefits and affordability of the LCS program. The modified LCS ships will complement the planned 32 LCS ships, resulting in a 52 ship Small Surface Combatant Fleet in keeping with the Navy's Force Structure Analysis. The 32 LCS ships, with their full modular capability, will allow the Navy to deploy assets to meet the Navy's mine warfare, SUW, and ASW demands.
