. She was christened in September 2006, delivered to the Navy in September 2008, and commissioned that November. During INSURV trials, 2,600 discrepancies were discovered, including 21 considered high-priority. Not all of these were rectified before the ship entered service, as moving the ship away from Milwaukee before the winter freeze was considered a higher priority.

Cost overruns during Freedoms construction combined with projected future overruns led the government to issue a "Stop-work" in January 2007 and ultimately led to the cancellation of construction of LCS-3 (the second Lockheed Martin ship) on April 13, 2007. This ship was later re-ordered.

After much inconsistency on how testing and orders were to proceed, in November 2010, the USN asked that Congress approve ten of both the Freedom and Independence classes.

Design

The ship is a semi-planing steel monohull with an aluminum superstructure. It is 377 feet (115 m) in length, displaces 2,950 metric tons, and can go faster than 45 knots (24.5 m/s). The design incorporates a large reconfigurable seaframe to allow rapidly interchangeable mission modules, a flight deck with integrated helicopter launch, recovery and handling system and the capability to launch and recover boats (manned and unmanned) from both the stern and side.

The flight deck is 1.5 times the size of that of a standard surface ship, and uses a Trigon traversing system to move helicopters in and out of the hangar. The ship has two ways to launch and recover various mission packages: a stern ramp and a starboard side door near the waterline. The mission module bay has a 3-axis crane for positioning modules or cargo.

The fore deck has a modular weapons zone which can be used for a 57 mm gun turret or missile launcher. A Rolling Airframe Missile launcher is mounted above the hangar for short-range defense against aircraft and cruise missiles, and .50-caliber gun mounts are provided topside.

The core crew will be 40 sailors, usually joined by a mission package crew and an aviation detachment for a total crew of about 75. Automation allows a reduced crew, which greatly reduces operating costs, but workload can still be "grueling". During testing of the class lead
