July 30,
2008: The US Navy's first "Littoral
Combat Ship" (LCS), the USS Freedom (LCS 1), began sea trials on July 28th. Three years ago, when construction began on
LCS 1, it was to displace 2,500
tons, with a full load draft of under
ten feet (permitting access to very shallow "green" and even "brown" coastal and riverine waters, where most naval
operations have taken place in the past generation. Top speed is expected was
to be over 80 kilometers with a range of 2,700 kilometers. The 378 foot long
ship still has the range and top speed it was designed for. Basic endurance is
21 days.
Built
using "smartship" technologies, which greatly reduce personnel requirements,
the basic LCS was expected to require a
crew of about 50 in basic configuration, but will have billeting for about 75 personnel. The sea trials will give
the smartship features a workout. These sea trials are very important, because
the LCS is over budget, behind schedule and, worst of all, an untried new
concept.
The LCS is
designed for a variety of interchangeable modules (e.g., air defense,
underwater warfare, special operations, surface attack, etc.), which will allow
the ships to be quickly reconfigured for various specialized missions. Crews
will also be modularized, so that
specialized teams can be swapped in to operate specific modules.
There are
actually two different LCS designs, a semi-planning monohull from Lockheed-Martin and a trimaran from
General Dynamics. LCS 1 was laid down by Lockheed Martin in Marinette,
Wisconsin, in June of 2005 and was expected to be commissioned in 2007, after
months of sea tests in late 2006.
LCS 2 was
laid down by General Dynamics in late 2005. These, and LCS 3 and LCS 4, were to be built by Lockheed and General
Dynamics, respectively. These were essentially prototypes, and serial procurement
was expected to begin this year, after initial design flaws had been worked
out. Ultimately, the Navy hoped to have
between 50 and 60 LCSs by 2014-18, at a cost of $90 million each.
As it
turned out, there were a lot of problems. The USS Freedom ended up costing $500
million, about twice what the first ship in the class was supposed to have
cost. Only one of each type of LCS will be built now, and the one that performs
the best will become the model for the entire class. LCS 1 ended up displacing 2,900 tons, and
most observers in 2005 believed that it would end up closer to 3,000 tons, than
2,500.
The
initial sea trials (being conducted on Lake Michigan), are expected to be
completed by the end of the year. After that, the ship will head for its home
port, San Diego, but only if the sea trials demonstrate that LCS works.
