"We have now completed successful sea trials on eight LPDs, and our sea trial
team continues to perform magnificently," said Doug Lounsberry, Ingalls' vice
president of the LPD program. "Our shipbuilders, and specifically the LPD 24
team, did an outstanding job in getting this ship prepared for this trial. We
have a hot production line associated with the LPD program, and through our
new build strategies and planning processes, more outfitting is taking place
in the shops, which improves our efficiency. We will continue this trend as
the premier builder of amphibious ships for the U.S. Navy."

While at sea in the Gulf of Mexico, the U.S. Navy's Board of Inspection and
Survey (INSURV) observed more than 200 test events demonstrated on the ship by
Ingalls' test and trials team. The team thoroughly tested ship systems such as
anchor handling, flight operations, steering, navigation, and ballasting and
de-ballasting the well deck. The team also performed a full power
demonstration.

"We have a good working relationship with Supervisor of Shipbuilding (SUPSHIP)
Gulf Coast, and together, we had a very good sea trial," said Richard Schenk,
Ingalls' vice president of test and trials. "LPD 24 is a great ship, and she
performed well for INSURV. We even had an opportunity to steam in formation
with Anchorage (LPD 23) while at sea. It takes a great deal of logistical
planning to pull off such a successful trial, and I would like to congratulate
the Ingalls and SUPSHIP teams for making this a success."

The 11 ships of the LPD 17 class are a key element of the Navy's ability to
project power ashore. Collectively, they functionally replace more than 41
ships (the LPD 4, LSD 36, LKA 113 and LST 1179 classes of amphibious ships),
providing the Navy and Marine Corps with modern, sea-based platforms that are
networked, survivable and built to operate with 21st century platforms, such
as the MV-22 Osprey.

Ingalls has delivered seven ships in the class and has four more in various
stages of construction, including Arlington (LPD 24), which will be
commissioned next spring.

The LPD 17-class ships are 684 feet long and 105 feet wide and displace
approximately 25,000 tons. Their principal mission is to deploy the combat and
support elements of Marine Expeditionary Units and Brigades. The ships can
carry up to 800 troops and have the capability of transporting and debarking
air cushion (LCAC) or conventional landing crafts, augmented by helicopters or
vertical take-off and landing aircraft such as the MV-22. These ships will
support amphibious assault, special operations or expeditionary warfare
missions through the first half of the 21st century.
