Fifth high-speed vessel

The Navy christened the future USNS Trenton (JHSV 5) January 10 during a 10 a.m. CDT ceremony in Mobile, Alabama. «This ship represents the hard-working men and women of New Jersey and the importance of the American cities along the Delaware River. It represents American shipyard, factory, and assembly line workers who have been the backbone of the Arsenal of Democracy since President Franklin Roosevelt coined the phrase more than seven decades ago. It represents the American spirit of hard work, patriotism and perseverance», said Secretary of the Navy Ray Mabus. «The USNS Trenton will carry these values and this spirit around the world. It is tailor-made for our 21st century operations and maritime security missions, from the wide expanses of the Pacific to the littorals of Africa».

JHSV 5 will be the fourth naval vessel to bear the name Trenton. The first ship was built following the Civil War and was named to honor George Washington’s Revolutionary War victory on the banks of the Delaware River. Since then, a ship bearing the name Trenton has served during every vital Navy mission until 2007 when the last ship was decommissioned.

The 338 foot-long (103 m) aluminum catamaran is under construction at the Austal USA shipyard in Mobile, Alabama. JHSVs are ideal for fast, intra-theater transportation of troops, military vehicles, supplies and equipment. These ships are capable of transporting 600 short tons 1,200 nautical miles (2,222 km) at an average speed of 35 knots (65 km/h) with berthing space for up to 104 personnel and airline-style seating for up to 312.

JHSVs have a 20,000 square foot (1,863 m2) open mission deck and a flight deck to support day and night launch and recovery operations, providing U.S. forces added mobility and flexibility. They can operate in a variety of roles to include supporting overseas contingency operations, conducting humanitarian assistance and disaster relief, supporting special operations forces and supporting emerging joint sea-basing concepts.

Upon delivery to the U.S. Navy’s Military Sealift Command, Trenton will be designated as a United States Naval ship, and will have a core crew of 22 civilian mariners with military mission personnel embarking as necessary.
