LCS: Designs & Teams

Guest User

There are currently 2 different LCS designs being produced and procured as part of the competition.

LCS-1 Freedom Class Monohull

Team Lockheed Martin’s LCS-1 Freedom Class offers a proven high-speed semi-planing monohull, based on Fincantieri designs that have set trans-Atlantic speed records. The design will use the firm’s COMBATSS-21 combat system as the fighting electronic heart of the ship, has shock-hardened the engine systems, and uses a combination of a steel hull and aluminum superstructure. USS Freedom has faced persistent reports of weight and stability issues, however, which required additional bolt-on buoyancy fittings at its stern.

The ships have a smaller flight deck than the Independence Class at 5,200 square feet, but a larger 4,680 square foot helicopter hangar. The Freedom Class’ LCS mission bay is the biggest difference – it’s under half the size, at 6,500 square feet. On the other hand, its RAM missile launcher is the 21-round Mk.49, and if the ships need weapon upgrades, export designs stemming from the Freedom Class mount full strike-length Mk.41 vertical launch cells. These can handle any vertically-launched system in the fleet, including SM-3 anti-ballistic missile interceptors, and Tomahawk long-range precision attack missiles.

Lockheed’s core team includes various Lockheed divisions, plus naval architects Gibbs & Cox of Arlington, VA; shipbuilder Bollinger Shipyards of Lockport, LA; and shipbuilder Marinette Marine of Marinette, WI. Niche providers and related partnerships include:

LCS-2 Independence Class Trimaran

The LCS-2 Independence Class offers a futuristic but practical high-speed trimaran, based on Austal designs and experience with vessels like the US Marines’ Westpac Express high-speed transport, and the Army and Navy’s TSV/HSV ships. It offers an especially large flight deck (7,300 square feet) and internal mission volume (15,200 square feet mission bay) for its size, with a 3,500 square foot helicopter hangar. The hull is aluminum, but the trimaran design offers additional stability options, and may help the ship survive side hits.

The Independence Class will carry a General Dynamics designed combat system, and standard LCS weapon fittings. The RAM defensive missile launcher sacrifices some size, but the 11-round SeaRAM is a self-contained unit with its own radar. If the LCS should require a full suite of naval weapons in future, export designs based on the this class tout “tactical-length” vertical launch cells that are limited to shorter weapons like RIM-162 ESSM and SM-2 air defense missiles, and VL-ASROC anti-submarine missiles.

Not anymore…

The initial teaming arrangement was led by General Dynamics Bath Iron Works shipbuilder as prime integrator, with Austal of Mobile, AL (a subsidiary of Austal Ships of Australia) as the main design partner and ship-building site. That alliance was broken by the requirements of the 2010 RFP, which demanded a 2nd builder for the designs that was unaffiliated with the first.

Austal is now the sole prime contractor for the LCS-2 Independence Class design. GD subsidiaries remain heavily involved, including General Dynamics Armament and Technical Products Division in Burlington, VT; General Dynamics Electric Boat Division in Groton, CT; General Dynamics Advanced Information Systems in Fairfax, VA; and General Dynamics Canada in Ottawa, Ontario. Other key participants include:

  • Boeing in Seattle, WA

  • BAE Systems in Rockville, MD

  • L3 Communications Marine Systems in Leesburg, VA

  • Northrop Grumman Electronic Systems in Baltimore, MD

  • Maritime Applied Physics Corporation in Baltimore, MD

  • GE (LM 2500 gas turbines)

  • MTU (8000 Series diesel engines)

  • Saab (AN/SPS-77v1 Sea Giraffe AMB  radar)

  • Wartsila (water jets )
