Navy to Deploy Electromagnetic Railgun Aboard JHSV

 

 

Apr 7, 2014 ASDNews Source : US Navy

 

The U.S. Navy plans to install and test a prototype electromagnetic railgun aboard a joint high speed vessel in fiscal year 2016, the service announced today.

 

This test will mark the first time an electromagnetic railgun (EM railgun) has been demonstrated at sea, symbolizing a significant advance in naval combat.

 

EM railgun technology uses an electromagnetic force - known as the Lorenz Force - to rapidly accelerate and launch a projectile between two conductive rails. This guided projectile is launched at such high velocities that it can achieve greater ranges than conventional guns. It maintains enough kinetic energy that it doesn't require any kind of high explosive payload when it reaches its target.

The US Navy has taken delivery of the third Spearhead-class joint high-speed vessel (JHSV), USNS Millinocket (JHSV 3), from Austal USA in Mobile, Alabama, US, marking a major milestone in the ship's transition to operational status.

 

The 103m-long high-speed catamaran has been designed as part of the US Department of Defense's (DoD) ten-ship contract, worth more than $1.6bn, to support theatre cooperating missions, US Marine Corps, Seabees and Army transportation.

 

Strategic and Theater Sealift programme manager Captain Henry Stevens said: "Millinocket's speed, agility and cargo capabilities will be an asset to operations around the world."

 

Capable of transporting 600t of military cargo 1,200nm at an average speed of 35k, the JHSV can support a wide range of operations including non-combatant evacuation operations, humanitarian assistance and disaster relief.

 

Military Sealift Command (MSC) commander Rear Admiral Shannon said: "The JHSV ship class, including USNS Millinocket, will play an important part in the future of our joint forces in terms of affordability, flexibility, speed and agility."

 

The 2,400t versatile, non-combatant, transport ship can accommodate a crew of 42 and can cruise at a maximum speed of 43k using four MTU 20V8000 M71L diesel engines driving four Wartsila WLD 1400 SR waterjets through four ZF 60000NR2H reduction gears.

 

Equipped with Navair level 1 class 2 certified flight deck to support the CH-53E Super Stallion helicopter operations, the vessels can be used for military logistics and humanitarian relief operations, in addition to transportation of troops, military vehicles, cargo and equipment.

 

Owned and operated by MSC, USNS Millinocket will be manned by a crew of 22 civil service mariners.

A ceremony celebrating the laying and authentication of the keel of the future USNS Trenton (JHSV 5) was held at the Austal USA shipyard, today.

 

The keel was authenticated by the ship's sponsor, Virginia Kamsky, who confirmed that it was truly and fairly laid. Although the laying of the keel has historically signified the start of ship fabrication, modern technologies make it possible for the shipbuilding process to commence months before the keel has been laid.

 

"I want to thank our shipbuilders who are working so hard, from each keel laying to each delivery, to ensure the Navy receives the strongest, most flexible and capable ships possible," said Capt. Henry Stevens, Strategic and Theater Sealift Program Manager, Program Executive Office (PEO), Ships. "Trenton's keel laying marks the first significant milestone in her journey to delivery and eventual support of a variety of missions around the world."

 

JHSV 5 benefits from program maturity, building on the lessons learned from the earlier ships in the class. The ship leverages commercial design and technologies to ensure design stability and lower development costs.

 

Upon completion, USNS Trenton will be used for the rapid transport of troops, equipment, and supplies over operational distances, in support of a variety of missions including maneuver and sustainment, humanitarian assistance and disaster relief. JHSV 5 is capable of transporting 600 short tons of military cargo 1,200 nautical miles at an average speed of 35 knots.

 

The JHSV is capable of interface with roll-on/roll-off discharge facilities, features an off-load ramp and a flight deck, and has a shallow draft of less than 15 feet. Its speed and ability to access austere port environments, as well as the size and versatility of its cargo capabilities, makes the JHSV an extremely flexible asset for support of a wide range of operations.

 

The fourth ship to be named after New Jersey's capital city, JHSV 5 honors the values and the men and women of the city as well as the state of New Jersey. USNS Trenton will be owned and operated by Military Sealift Command (MSC), operating within MSC's Sealift program. She will be manned by a crew of 22 civil service mariners with military mission personnel embarking as required.

 

As one of the Department of Defense's largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships and special warfare craft. Delivering high-quality warfighting assets - while balancing affordability and capability - is key to supporting the Navy's Maritime Strategy.

Austal building high speed support vessels for Middle East customer

 

 

HENDERSON, Australia, March 10 (UPI)

 

An unidentified Middle Eastern customer has contracted Australian shipbuilder Austal Limited to supply two high speed support vessels.

 

The contract is worth $124.9 million and includes provision of integrated logistics support, the company said.

 

"This contract reinforces the significant progress we have made in positioning Austal as a prime defense contractor," said Austal Chief Executive Officer Andrew Bellamy. "The contract also illustrates the growing recognition by international naval forces of the utility of high speed support vessels, following on from our 10-ship Joint High Speed Vessel contract for the U.S. Navy."

 

High speed support vessels are shallow draft ships for rapid intra-theater transport of medium-sized cargo payloads. JHSVs of the U.S. Navy will reach speeds of 35-45 knots. In addition to transport, the vessels can support helicopter operations and search-and-rescue operations.

 

Austal said under the contract, the vessels for the Middle Eastern customer will each be 236 feet long. Construction of the first will begin this year at its shipyard in Henderson in western Australia.

USNS Millinocket (JHSV 3) successfully launched, June 5, from the Austal USA shipyard in Mobile, Ala.

 

The third joint high speed vessel is a versatile, non-combatant, transport ship that will be used for fast intra-theater transportation of troops, military vehicles and equipment.

 

"This launch is an important achievement for the program, as it's the first time the ship has entered the water," said JHSV program manager Capt. Henry Stevens. "Launching signifies a ship is ready to enter into the final phase of construction including test and activation of major equipment such as the propulsion plant."

 

Millinocket will now prepare for a series of trials conducted by the shipbuilder, testing overall system performance underway prior to demonstration to the Navy's Board of Inspection and Survey later this year.

 

Each JHSV is designed to commercial standards, with limited modifications for military use. These vessels can transport 600 short tons 1,200 nautical miles at an average speed of 35 knots and can operate in shallow-draft ports and waterways, providing U.S. forces added mobility and flexibility. The ships also have an aviation flight deck to support day and night air vehicle launch and recovery operations. JHSVs have berthing space for up to 104 personnel and airline-style seating for up to 312.

 

JHSV 3 is one of two JHSVs currently under construction at Austal. The future USNS Fall River (JHSV 4) held a keel laying and authentication ceremony May 20, and JHSV 5 started fabrication in February. USNS Choctaw County delivered June 6. The lead ship of the class, USNS Spearhead, was delivered to the Navy in December 2012. A total of ten JHSV class ships are under contract with Austal.

 

Millinocket is designated as a U.S. Naval Ship (USNS), signifying its civilian crew. The vessel will have a core crew of 22 civilian mariners who will operate and navigate the ship as part of the U.S. Navy's Military Sealift Command.

The Navy accepted delivery of the second Joint High Speed Vessel, USNS Choctaw County (JHSV 2), from Austal USA, June 6 in Mobile, Ala.

 

JHSV 2 successfully completed acceptance trials in May, when the Navy's Board of Inspection and Survey evaluated performance of the ship's major systems and equipment. Delivery represents the official transfer of the ship from the shipbuilder to the Navy.

 

"This ship is delivering just six months after the first ship in the class, USNS Spearhead, delivered, a commendable accomplishment for this dedicated Navy-shipbuilding team," said JHSV program manager Capt. Henry Stevens. "With their high-speed, on-load and off-load capabilities and maximized cargo space, these vessels will provide the fleet versatile and flexible capabilities for decades to come."

 

JHSV 2 will be owned and operated by the Military Sealift Command. Pending the completion of crew move-aboard and familiarization, JHSV 2 will sail away from Austal USA's shipyard later this summer.

 

"USNS Choctaw County is a welcome addition to our Navy's fleet and we are confident that our civilian mariners are ready to operate this uniquely fast and flexible ship wherever and whenever needed around the world," said Rear Adm. T.K. Shannon, commander, Military Sealift Command.

 

Intended to provide transportation in shallow-draft waterways and ports, the JHSV is capable of transporting 600 short tons at least 1,200 nautical miles at an average speed of 35 knots. The ship also features a flight deck designed to support helicopter operations and a fast-rescue boat mounted midship on the port side. The vessel has airline-style seating for 312 embarked forces, with fixed berthing for 104.

 

MSC operates approximately 110 non-combatant, civilian-crewed ships that replenish U.S. Navy ships, conduct specialized missions, strategically preposition combat cargo at sea around the world and move military cargo and supplies used by deployed U.S. forces and coalition partners.
