JHSV 1 completes builder’s sea trials

Shipbuilder Austal USA, Mobile, Alabama, reports that Joint High Speed Vessel USNS Spearhead (JHSV 1) has completed builder’s sea trials in the Gulf of Mexico.

The trials encompassed over 50 demonstration events that enabled the shipbuilder to rigorously test the ship and all of its systems in preparation for final inspection by the U.S. Navy before delivery.

Trials included a demonstration of major systems along with first-of-class standardization and maneuverability trials, reaching a top speed in excess of 35 knots.

A series of high-speed ahead and astern maneuvers in the Gulf of Mexico demonstrated the effectiveness of the ship’s four steerable water jets.

In the course of repeated high-speed turns, says Austal, the ship demonstrated the stability and agility of the catamaran hullform, with the JHSV exhibiting virtually no heeling motions throughout the radical turns.

On returning from the full-power trial, Joe Rella, President and Chief Operating Officer of Austal USA, remarked: “The successful first run trials for this prototype vessel validate the quality and reliability of Austal’s shipbuilding knowhow. I have never witnessed a more problem-free builder’s sea trial than USNS Spearhead’s. The global Austal organization successfully participated in the design, procurement, and production of this ship with a great outcome, all being accomplished while locally, Austal USA continues to hire new workers and expand our facilities. This is a telltale sign of the dedication of our team of shipbuilding professionals.”

Austal is currently under contract with the U.S. Navy to build nine 103-meter JHSVs at the Mobile shipyard under a 10-ship, $1.6 billion contract and five 127-meter Independence-variant Littoral Combat Ship (LCS) class vessels, four of which are a part of a 10-ship, $3.5 billion contract.

For the LCS and JHSV programs, Austal, as prime contractor, is teamed with General Dynamics Advanced Information Systems, a business unit of General Dynamics. As the ship systems integrator, General Dynamics is responsible for the design, integration and testing of the ship’s electronic systems including the combat system, networks, and seaframe control. General Dynamics’ proven open architecture approach allows for affordable and efficient capability growth as technologies develop.

Austal has grown into one of southern Alabama’s largest employers with over 2,800 employees on staff hailing from the Mobile Area, Mississippi, Florida, and beyond. Under the current workload, Austal expects to employ over 4,000 people by the end of 2013.
