LCS 2 completes builder's trials

General Dynamics reports that Independence (LCS 2), the LCS being constructed by shipbuilder Austal USA in Mobile, Ala., as part of the General Dynamics Littoral Combat Ship Team, successfully completed builder's trials on October 18 in the Gulf of Mexico. The trials included more than 50 demonstration events to test the ship and all of its systems in preparation for final inspection by the Navy before delivery.

Notable achievements during the trials included reaching a sustained speed of 44 knots during the required four-hour full-power run, with a top speed in excess of 45 knots.

Many of the test events were conducted in high sea-state and wind conditions (8-foot waves and winds in excess of 25 knots). Despite the weather, says General Dynamics, the ship repeatedly reached speeds of over 45 knots with propulsion and ride-control systems operating in full automatic mode, proving the effectiveness of the control systems and the highly efficient and stable characteristics of the trimaran hull form.

A series of high speed ahead and astern maneuvers in these sea state conditions proved the effectiveness of the ship's four steerable water jets. During the repeated high-speed turns, says GD, the ship demonstrated excellent agility and stability characteristics.

The ship's flight deck remained stable despite sea state conditions and maneuvers.

The ship's open architecture computing infrastructure (called OPEN CI), a flexible information-technology backbone that integrates the ship's combat, damage control, engineering control, mission package and other onboard computing functions, also proved its effectiveness during the trials. The OPEN CI 'any display, anywhere' capability was extremely valuable in enabling the LCS 2 crew to electronically reconfigure the bridge area and, at long range, the Core Mission System successfully detected, engaged and eliminated a simulated cruise missile attack by a small, fast-moving jet aircraft.

In addition, the LCS 2 crew was able to access detailed performance and operation data from the bridge while the ship was operating, thereby providing them with real-time insight as to how the ship systems were performing.

Jeff Geiger, president of team-leader Bath Iron Works, was on-board for the ship's high-speed trials on October 15. He said, "Independence exceeded our expectations in terms of maneuverability, stability, handling and speed. We are very pleased to be one step closer to delivering this highly capable, versatile and lethal platform to the United States Navy."

In addition, Geiger praised the builder's trials team for a job well done: "I'm proud of this entire team of professionals, including Navy representatives from SUPSHIP, Bath and Washington, D.C., who were beside us every step of the way, for their hard work and perseverance."

On returning from the full-power trial, Joe Rella, president and chief operating officer of Austal USA, remarked: "The LCS did extremely well. Mobile and Alabama can be justifiably proud of their shipbuilders."
