Christening of Brunswick

The Navy christened the future joint high-speed vessel USNS Brunswick (JHSV-6) on May 9, 2015, during a 10 a.m. CDT ceremony in Mobile, Alabama. Secretary of the U.S. Navy Ray Mabus delivered the ceremony’s principal address. Alma B. «Lee» Booterbaugh served as the ship’s sponsor.

More than 300 naval guests, civic leaders, community members and Austal employees attended Saturday's ceremony, which was held beneath the hull of the Brunswick at Austal's shipyard

«We are celebrating the christening of the future USNS Brunswick – a modern marvel – just like the incredible shipyard that built it», said Mabus. «More than 4,000 American craftsmen have made this ship possible and the partnership they have with our uniformed men and women, our Navy civilians, the shipbuilding industry as a whole, and the American people, is one of the great strengths of our system. Throughout its life, as it serves around the world, this ship will represent the American spirit of hard work and patriotism the people of Brunswick exude».

Named for a seaport city located on the southeast coast of Georgia, Brunswick is the fourth ship to bear the name. The first was a lightship that served in the U.S. Navy during World War I. The second Brunswick was a patrol frigate that escorted convoys across the Atlantic during World War II. The third ship to bear the name was a salvage and rescue tug that served the U.S. Navy from 1972 to 1996.

Three JHSVs and seven Littoral Combat Ships (LCS) are currently under construction in Austal’s Mobile, Alabama shipyard. The company is scheduled to launch JHSV-6 before the end of the month, while the future USS Jackson (LCS-6) prepares for its acceptance sea trials later this summer

The 103 m/338 foot-long aluminum catamaran is under construction at the Austal USA shipyard in Mobile, Alabama. Joint High Speed Vessels (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/40 mph/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 (MSC), Brunswick (JHSV-6) will be designated as a United States Naval Ship (USNS), and will have a core crew of 22 civilian mariners with military mission personnel embarking as necessary.
