The US Navy's newest Independence-class littoral combat ship (LCS) USS Omaha (LCS 12) has successfully completed its sea acceptance trials before being delivered to the navy.

The trials follow after the vessel completed a series of graded in-port and underway demonstrations for the US Navy's Board of Inspection and Survey (INSURV).

USS Omaha underwent a comprehensive series of tests during the trial period in order to assess the performance capability of the propulsion plant, ship handling and other auxiliary systems.

The US Navy vessel also successfully conducted launch and recovery operations of the 11m-long rigid-hull inflatable boat.

USS Omaha has also completed surface and air self-defence detect-to-engage exercises, in addition to demonstrating its manoeuvrability through high-speed steering, crash backs and a four-hour full power run.

LCS programme manager captain Tom Anderson said: “The navy / industry trials team in Mobile has found their stride and, with stability in the serial production line, are bringing ships to trial with consistently improved performance at decreasing cost.

“Omaha will be an exceptional addition to the rapidly growing in-service fleet.”

The vessel will sail to California for commissioning after the delivery, as well as post-delivery maintenance availability and crew training and familiarisation exercises in Mobile, Alabama.

It will be then be homeported in San Diego with its sister ships USS Independence (LCS 2), USS Coronado (LCS 4), USS Jackson (LCS 6), USS Montgomery (LCS 8) and USS Gabrielle Giffords (LCS 10).

Additionally, the US Navy’s Freedom-class LCS USS Detroit (LCS 7) has completed final contract trials (FCT) after a five-day evaluation period.
