U.S. Navy's X-47B program ramps up flight test, readying for summer sea trials
The X-47B Unmanned Combat Air System demonstrator (UCAS-D) is gearing up for shore-based flight test activities in preparation for the next round of sea trials this summer. The program’s test team will conduct various test events with the X-47B over the next few months in an effort to mature air traffic control and ground support standard operating procedures for co-use of airspace between unmanned and manned aircraft during day and nighttime operations.
“Continuing to fly the X-47B in the Patuxent River air space will further exercise the research, test, development and evaluation (RDT&E) infrastructure with an unmanned air system,” said Capt. Beau Duarte, program manager for Unmanned Carrier Aviation at Patuxent River. “These tests are a build-up for the next carrier event this summer.”
As the first unmanned aircraft to take off and land from a modern aircraft carrier, X-47B will once again embark on USS Theodore Roosevelt (CVN 71) in the August timeframe. This time, the test team will focus on perfecting flight deck operations and integrating the X-47B with manned carrier aircraft.
“We are working toward a new set of firsts for the X-47B,” said Matt Funk, X-47B lead test engineer. “We’ll test the new capabilities of the X-47B wing-fold and tailhook retract system, and will demonstrate compatibility with a carrier jet-blast deflector on the flight deck for the first time.”
The proven use of these functions will allow the air vehicle to take off, land, and hold in the same pattern as manned aircraft, the next step toward UAS operations aboard aircraft carriers without disruption to normal carrier flight deck operations, he said.
“This at-sea period will mark the first time manned aircraft and the X-47B will operate together on the flight deck,” Duarte said. The goal is to clear the deck within 90 seconds after landing and demonstrate deck handling on par with manned aircraft.
The U.S. Navy will conduct X-47B flight operations over the next year to mature technologies for the future Unmanned Carrier Launched Airborne Surveillance and Strike system and refine the concept of operations to demonstrate the integration of unmanned carrier-based aircraft within the carrier environment, Duarte said.

US Navy Task Force Seeks Industry Ideas
WASHINGTON — The search for a possible follow-on to the US Navy’s Littoral Combat Ship (LCS) took a step forward Wednesday with the publication of two requests for information (RFIs). One RFI seeks input on ship designs, and the other is aimed at combat systems. “We’re asking for existing and mature design concepts,” John Burrow, lead for the Small Surface Combatant (SSC) task force, told reporters at the Pentagon. The second RFI, he explained, asks for information on “combat systems and technologies at the component level,” such as radars and weapons. The task force was formed in mid-March to provide the Navy and Pentagon leaders with options and alternatives to the LCS. Those options, Defense Secretary Chuck Hagel said earlier this year, could include the existing LCS designs. The effort is on a fast track. The task force is to submit its findings by July 31, in time, Hagel said, “to inform” the 2016 budget deliberations. Issuance of the RFIs, Burrow said, “will really kick the engagement for us” and give industry the chance to present its ideas. “We’re not providing requirements in the RFIs,” Burrow said. “We’re looking for what systems and capabilities are out there right now. We’re not looking for them to do a design effort, but they’ve been thinking about this for some time, and I’m sure they have some good ideas.” The task force, Burrow explained in his first meeting with reporters since the group was formed, is developing capability concepts, along with mission and capability alternatives for the ships. Among the options to be considered, he said, are modifications to the current LCS 1 Freedom class design from Lockheed Martin, and the LCS 2 Independence class from Austal USA. “Each one may have a number of configuration alternatives,” he said. “In the end, when we come up with alternatives they will be tied to capability concepts that will be closely linked to the engineering analysis.” The capability concepts are centered on four key warfare areas: air, surface, undersea and mines. Along with those areas, Burrow said, will be capabilities like speed, range and endurance. “We have a designed set of capabilities and a level of capability for each,” he said. Asked about affordability targets, Burrow said that while the work of the task force will “inform the process, this task force does not make affordability decisions. “My job is to give design alternatives that include capability concepts, design alternatives, cost and performance. We’ll start big and eliminate some [alternatives], start to get it down to a more manageable set of alternatives that leadership can use to make a decision.” Asked if foreign designs were off the table, Burrow exclaimed, “not at all. “We’re looking at ships in production today and mature designs. We’re looking at everything,” including foreign designs. The task force also is beginning efforts to reach out to the fleet for input on what a small warship would need. The group will travel to Norfolk and Pearl Harbor in May to begin that process, Burrow said.

Boeing Delivers 100th EA-18G Growler to US Navy
Need for additional Navy and joint forces electronic-attack capability highlighted at delivery ceremony
ST. LOUIS, Mo., May 5, 2014 -- Boeing [NYSE: BA] delivered the 100th EA-18G Growler to the U.S. Navy, marking a major milestone in the program that has transformed airborne electronic warfare capability for the U.S. and its allies.
A derivative of the F/A-18F Super Hornet, the Growler is the only aircraft in production that provides tactical jamming and electronic protection for U.S. and allied forces. Growlers provide a unique capability to nearly all U.S. combat missions and are expected to be in service until at least 2040.
"Given the threat environment we are moving into, the Growler will play a major role in identifying, tracking, targeting and potentially firing upon the enemy," said Capt. Frank Morley, U.S. Navy F/A-18 and EA-18G program manager, during the delivery ceremony today in St. Louis. "The EA-18G Growler is a high-demand asset that is equally critical in disrupting our enemies operations as it is enhancing our own."
The U.S. Navy has 22 Growlers on its unfunded priorities list for the 2015 fiscal year budget. Current orders take Growler and Super Hornet production through the end of 2016.
"Today we celebrated 100 Growler deliveries – all on cost and on schedule – and highlighted the need for additional Growlers in the future so our men and women in uniform can prosecute their missions in the safest, most effective way possible," said Mike Gibbons, F/A-18 and EA-18G Programs vice president. "We believe there is a compelling case to be made that the Navy needs 50 to 100 more aircraft to meet future requirements."
During testimony on March 27 to the U.S. Senate Armed Services Committee, Adm. Jonathan Greenert, chief of naval operations, described the Growler as an "extraordinary capability" and emphasized the need for more aircraft.
The Growler and Super Hornet programs support 60,000 jobs in the U.S., with 800 suppliers in 44 states and account for $3 billion in annual economic impact. For more information on the Growler, visit Boeing’s website, SupportGrowler.com

Sikorsky Wins U.S. Navy Contract to Replace ‘Marine One’ Helicopter Fleet
Stratford, Connecticut - The U.S. Navy today announced that Sikorsky Aircraft, a subsidiary of United Technologies Corp. (NYSE:UTX), has been selected to build the next fleet of Marine One helicopters for the Office of the President.
With the selection comes a $1.24 billion Engineering and Manufacturing Development (EMD) contract to modify, test and deliver six FAA-certified S-92® helicopters and two trainer simulators to the U.S. Marine Corps. Covering a period of performance into late 2020, the fixed price incentive firm contract is the initial step to providing, by 2023, a VXX Presidential Helicopter Replacement fleet totaling 21 operational aircraft.
“We are honored by this news and the vote of confidence in the Sikorsky team and the proven S-92 platform,” said Sikorsky President Mick Maurer. “For 57 years, our company has been trusted with the critical responsibility of building and supporting a safe and reliable helicopter fleet for the President of the United States. We are proud of our record and the bright future for our company. We stand ready to deliver the next Marine One, the world’s most advanced executive transport helicopter.”
Ten nations currently fly the dual-engine, medium-lift S-92 helicopter for their head of state missions. Since 2004, Sikorsky has delivered more than 200 S-92 helicopters, predominantly to operators serving the worldwide offshore oil and gas industry, and for civil search and rescue.
Sikorsky submitted its VXX proposal for an existing, in-production helicopter platform to the Navy in August 2013, following a Request for Proposals in May of the same year.
Of the six contracted aircraft, two will be designated Engineering Development Models (EDM), enabling the Department of the Navy at Naval Air Station Patuxent River in Maryland to test the platform’s flight performance and mission communication system capabilities as certified by the Federal Aviation Administration. Sikorsky is contracted to deliver the two EDM aircraft during 2018.
The remaining four aircraft — designated System Demonstration Test Articles (SDTA) — will perform operational test and evaluation, and then transition to operational status. Sikorsky will deliver two training simulators (one each for maintainers and pilots) ahead of aircraft deliveries in 2018.
By early 2019, the Navy is expected to place orders for the first of three lots of 17 production aircraft. Sikorsky expects to complete delivery of these production aircraft by 2023.
The Sikorsky team will produce the aircraft in four distinct stages.
Assembly of the baseline “commercial off-the-shelf” flight-certified aircraft will occur at the company’s S-92 production facility in Coatesville, Pennsylvania, near Philadelphia.
At a secure facility in its Stratford, Connecticut, headquarters, Sikorsky will perform aircraft modifications to meet the requirements of the presidential mission.
Later, at a secure facility in Owego, New York principal subcontractor Lockheed Martin Mission Systems and Training will install the integrated communications and mission systems.
When aircraft are returned to Stratford, Sikorsky will install the presidential interior into the 6-foot-high by 20-foot-long by 6.5-foot-wide cabin, and deliver the completed aircraft to the U.S. Navy.
Sikorsky Aircraft Corp., based in Stratford, Connecticut, is a world leader in helicopter design, manufacture, and service. United Technologies Corp., based in Hartford, Connecticut, provides a broad range of high technology products and support services to the aerospace and building systems industries.
This press release contains forward-looking statements concerning opportunities for development, production and sale of helicopters. Actual results may differ materially from those projected as a result of certain risks and uncertainties, including but not limited to changes in government procurement priorities and practices, budget plans, availability of funding and in the type and number of aircraft required; challenges in the design, development, production and support of advanced technologies; as well as other risks and uncertainties, including but not limited to those detailed from time to time in United Technologies Corporation’s Securities and Exchange Commission filings.

House Adds 5 Growlers, Amphib to Defense Budget
The House Armed Services Committee added funding to the 2015 defense budget for five EA-18G Growler aircraft, a new amphibious assault ship and the refueling of an eleventh aircraft carrier for the Navy.
The HASC’s full-committee mark-up of the 2015 National Defense Authorization Act adds $450 million to the legislation for production of five new Growler aircraft even though the Navy’s unfunded priorities list asked for as many as 22 new Growlers.
“The 22 aircrafts would enable us to increase five of our carrier air wing squadrons from five aircrafts, which is the current program of record to seven aircrafts and give us an additional capability. Now we are going to conduct a fleet battle experiment this summer off the East Coast with one of our carriers,” Vice Adm. Paul Grosklags, the Navy’s top uniformed acquisition official, told Congress within the last several months.
Grosklags added that the 22 additional Growlers are particularly needed because the existing EA-6B aircraft will all be retired by 2019.
As of February of this year, the Navy has 97 Growlers in the inventory. The formal program of record calls for 138 Growler aircraft, Lt. Rob Myers, Navy spokesman, added. Each Growler is said to cost $62 million, Boeing officials said.
Boeing is lobbying for more Growlers saying it needs to have at produce at least two Super Hornets or Growlers per month to keep its production line in St. Louis open.
“The domestic budget for FY15 (fiscal year) have no Super Hornets’ or Growlers so it’s very important to us for Congress to act on the request by the Navy for their unfunded requirements,” said Mike Gibbons, program manager for F/A-18 and EA-18G Growler aircraft.
Industry sources say the Growler is well suited to counter emerging air defense system threats due to its ability to both jam and detect enemy signals. Air defenses have become more mobile, digital and computerized, industry experts said, making them more difficult for stealthy aircraft to avert, they say.
However, some analysts such as Loren Thompson, a consultant for Lockheed Martin and Boeing, have said that fifth generation stealth fighters are equipped to respond to next-generation air defenses. He said the Growler could be more easily detectable and therefore alert potential enemies as to the presence of other aircraft.
The Congressional committee also added $800 million in new funds to procure a 12th LPD 17 amphibious dock landing ship. Senior Navy leaders, who have said there is a greater need for amphibs than there are available ships, have previously said the service would only procure 11 LPD 17s.
A group of retired Marine generals, including former Commandant Gen. James Conway and former CentCom Commander Sen. James Mattis, wrote a letter to Congress asking that more funding be allocated for amphibs. In particular, the letter requests funding for the 12th LPD 17 and asks that the effort form the basis of the Navy’s effort to procure a new amphib called LX®.
Navy officials have said that the new LX® amphibdesign could be a new design or a configuration of several existing ships such as the existing LSD 41/49 dock landing ship or LPD-17 San Antonio-class amphibious transport dock.
Overall, service leaders say they will come up short of the 33 amphibious warships which the Navy and Marine Corps deemed an acceptable number. The Navy currently has 29 amphibs.
Also echoing the need for more amphibs, Marine Corps Commandant Gen. James Amos said there is currently a gap in the Mediterranean because so many Marine Expeditionary Units and Amphibious Ready Groups are in the Central Command area of responsibility.
“There’s no question that we would like to have more amphibious ships. I’d like to have 50-plus amphibious ships,” Amos told lawmakers
The HASC mark-up also adds $483 million to the refueling and overall for the USS George Washington, an aircraft carrier whose continued service will keep the Navy’s carrier fleet at 11.
If the USS George Washington is retired and not refueled to serve the remaining 25 years of its service life – then the Navy’s carrier fleet will drop to 10. Along these lines, the HASC mark also added $298 million for reactor and power unit funding to support the USS George Washington’s mid-life refueling and overhaul, a process which can take up to four years to complete.
The HASC mark-up also decreased funding for the Navy’s new DDG 1000 destroyer by $54 million and decremented the Littoral Combat Ship by $450 million, reducing the planned purchase from three per year down to two.
The Committee also added $82 million for plussed-up Tomahawk missile production. It remains to be seen how the House Appropriations Committee and Senate Committees will address these issues — so these mark-ups, while influential and significant, have a long way to go before being finalized.

Raytheon's JSOW scores direct hits in back-to-back flight tests with U.S. Navy
Raytheon Company and the U.S. Navy showcased the operational capability of the Joint Standoff Weapon in challenging back-to-back flight tests. Launched from F/A-18F Super Hornets, at approximately 25,000 feet, two JSOW II C air-to-ground weapons flew preplanned routes before destroying simulated cave targets.
"These test shots further validate JSOW's ability to deliver decisive battlefield effects against one of the most challenging land targets facing our warfighters," said Celeste Mohr, JSOW program director for Raytheon Missile Systems. "Naval aviators employed JSOW's firepower in a tactically realistic cave scenario that included heavy radio frequency countermeasures. The result was two direct hits -- it's all about sharpening the edge."
JSOW C is designed to provide fleet forces with robust and flexible capability against high value land targets, at launch ranges up to 70 nautical miles.
About the Joint Standoff Weapon
JSOW is a family of low-cost, air-to-ground weapons that employ an integrated GPS-inertial navigation system and terminal imaging infrared seeker. JSOW C-1 adds the two-way Strike Common Weapon Datalink to the combat-proven weapon, enabling a moving maritime target capability.
» JSOW C-1 is the world's first network-enabled weapon with a range of more than 100 kilometers. » The U.S. Navy's first two JSOW C-1 free-flight tests also resulted in direct hits on their moving ship targets. » Raytheon is using company funding to develop a powered version of the JSOW that will have the potential to engage targets at more than 250 nautical miles.

US Navy : le railgun (canon électromagnétique), une arme digne d’Hollywood
Depuis trente ans, les États-Unis travaillent à la mise au point du railgun. Ce canon, aussi appelé canon électromagnétique, lance un projectile léger sans charge explosive à très haute vitesse. Le principe est d’accélérer par un champ magnétique (force de Lorenz) un projectile entre deux rails conducteurs, d’où le nom de railgun. L’énergie cinétique liée à cette vitesse (mach 7+) rend le projectile dévastateur mais nécessite une puissance électrique considérable. Dans les années 1980-1990, l’US Army voulut intégrer un railgun sur un char, mais la puissance nécessaire impliquait un volume de batterie disproportionné. Sur un navire de guerre, le railgun est moins pénalisé par ses encombrants accumulateurs. Sur un navire à propulsion nucléaire comme les nouveaux porte-avions américains à deux coeurs, un railgun ne manquera pas de puissance électrique.
OPÉRATIONNEL EN 2018
L’US Navy a financé deux railguns, l’un est fabriqué par General Atomics et l’autre par BAE Systems. Les essais à terre étant concluants, les railguns seront bientôt installés sur l’USNS Millinocket pour des essais en mer prévus pour 2016. Selon le contre-amiral Matthew Klunder, chef du département recherche de l’US Navy, le railgun sera opérationnel dès 2018. Au-delà de la prouesse technologique, ce système est très économique avec un projectile valant 20 000 euros, soit 20 à 60 fois moins qu’un missile antiaérien (400 000 à 1 200 000 euros). Par ailleurs, un missile est encombrant et se périme rapidement, tandis qu’un projectile solide de railgun est inerte et de toute petite taille (10 kg). Le problème d’emport de munitions face aux redoutées attaques par saturation serait résolu. Reste à connaître la cadencen de tir exacte du railgun, mais cela reste classifié. Avec cette arme, l’US Navy veut conserver son avance. Les premiers railguns seront destinés à la lutte anti-aérienne et antimissile. Avec une portée de 160 km, ils pourront atteindre un missile balistique comme les redoutés missiles antinavires chinois DF-21D. Un railgun est aussi capable d’atteindre une cible navale ou terrestre mais, sans charge explosive, il ne pourra effectuer de hardkill.

Navy to Accept New Rolling Airframe Missile
The Navy is getting ready to accept its first Block 2 Rolling Airframe Missiles (RAM) for ship defense — a new variant of the self-guided missiles now protecting a wide range of Navy ships including amphibious assault ships and the Littoral Combat Ship, service officials said.
“RAM provides the self-defense against cruise missiles, aircraft and small surface threats. It has a dual mode RF and IR guidance system that will guide it right to an inbound target,” said Jeffrey Meyer, business development manager, Raytheon.
The Block 2 RAM, now in low-rate-initial production, will be delivered to the Navy toward the end of the summer, Raytheon officials said. Overall, the Navy plans to acquire at least 502 RAMs between 2015 and 2019, said Lt. Robert Myers, a Navy spokesman.
The new Block 2 variant includes a new RF receiver, new navigation system and increased diameter to 6-inches, Raytheon officials said. The new missile variant also includes enhanced guidance algorithms and a more powerful dual-thrust rocket motor enabling the missile to reach longer ranges, Raytheon officials said.
The Block 2 missile is 9.45 feet long, weighs 194-pounds, and is able to reach supersonic speeds, according to Raytheon and Navy information.
The missile is able to intercept threats that are close to the surface by sea-skimming or diving in onto a target from a higher altitude, Meyer explained. The so-called kinematic or guidance improvements of the Block 2 missile give it an improved ability to counter maneuvering threats, Navy and Raytheon officials explained.
The RAM missile, designed to destroy incoming threats from within the horizon but not in the immediate vicinity of the ship, is currently on LHA big-deck amphibious assault ships, LSD Dock Landing Ships, LPD Amphibious Transport Docks, LHD amphibious assault ships and aircraft carriers including the first Ford-class carrier — the USS Ford (CVN 78).
The RAM is designed to function as part of a layered ship defense system by working in tandem with other defense systems.
“The ship’s sensor provides information to the ship’s combat management system and then the RAM weapons systems launcher interfaces with that combat management system and the target positional data is translated,” said Desnie Bear, RAM program official with Raytheon.
Co-produced by Raytheon in Tucson, Ariz. and a German firm called RAMSys, the RAM missile has been around and had continuous upgrades since the 1970s. However, RAM was first deployed in 1993.
The missiles’ built-in guidance systems allow it to zero in on radio frequencies or heat coming from an approaching enemy threat such as a helicopter, aircraft or cruise missile.
“It is autonomous in that once you get all the information from your combat system, it is fire-and –forget. You shoot it and the missile will take care of going to the target itself,” said Meyer.
For instance, the RF seeker built into the RAM can identify and zero in on radio signals coming from the seeker of a cruise missile.
“It uses not only an IR (infrared) imager or seeker but you also have the RF because many of the cruise missiles will be trying to use some sort of seeker to come after the ship. It is a passive RF receiver and the threat is broadcasting an RF signal to find the ship. The RAM will pick up on that radiated radar signature and hone on it,” said Brent Holtzen, RAM program official with Raytheon.
At the same time, cruise missile emit heat as well – so the RAM’s IR seeker can find them also,
“The advantage we have is if the RF gets turned off we also have an IR capability — so we can go after the threat with IR as well. Some cruise missiles are IR guided as well,” said Bear.
Earlier variants of the RAM are currently in use in the U.S., Germany, South Korea, Greece, Egypt, UAE Turkey and Japan, Raytheon officials said.
Worldwide, Raytheon has delivered more than 3,500 RAM missiles and 175 RAM launchers.

United States Navy selling its Oliver Hazard Perry FFG class frigates — ‘no reasonable offer refused’
EVER wanted to own your own warship? Now’s your chance to light the fires and kick the … erm, lifesavers. The US Navy has several up for grabs, “no reasonable offer refused”.
The cold-war era guided missile frigates may be difficult to find a mooring for, but one would certainly turn heads.
And the prices are rock bottom, supplier-direct, bargain basement great-big deals. Yes, used warship salesman US Secretary of Defense Chuck Hagel is literally giving them away.
And don’t think you’re getting a discontinued line: The Oliver Hazard Perry FFG class is still in use in navies around the globe — from Australia to Spain, Bahrain to Taiway, Turkey to Egypt.
Each one is 4100 metric tons of lean, mean fighting machine.
There is one catch: They only come in grey.
If you have the proper papers, you can probably even get one with its guns and missiles still attached. If not, the provision of the full-sized helipad and undercover parking space for two choppers should still impress.
But you’ll have to be quick.
Given the popularity of these ships, this deal can’t last long.
Taiwan has already been spotted giving the vessels the once-over, as has Thailand and Mexico. Out of the 11 ships on offer, only three don’t currently have an offer on them.
So how much could one of these babies sell for?
Well, each ship was worth about $200 million in 1978 dollars when they were first delivered (roughly $700 million in today’s terms). Since then they’ve undergone considerable depreciation and covered an impressive number of miles.
With all the optional extras removed (such as the towed sonar arrays, aircraft-tracking radars and 76mm cannon), the price is expected to be low. Very low.
In the hands of new nations these ships are likely to be stripped for spare parts to keep others running, though some have indicated they want to upgrade them to full combat capability.
But buyer beware: As the Royal Australian Navy discovered with the purchase and conversion of two US tank landing ships in the 1990s, there is no refund if the goods don’t live up to expectations.
Make sure you check for rust. Carefully.

U.S. Navy tests Surface Warfare Gun Module on USS Coronado (LCS 4)
The Littoral Combat Ship (LCS) Mission Modules (MM) program successfully completed the first Structural Test Firing (STF) of the 30mm gun mission module aboard USS Coronado (LCS 4) off the coast of Southern California April 30. The purpose of the STF is to challenge the ship in the most severe blast conditions of the weapon's fire. STF is a total ship test involving live weapons fire and is required for each ship class or variant.
"Tested and proven on the LCS Freedom variant, this structural test firing marks the first critical step in demonstrating the surface warfare mission package capability on the LCS Independence variant," said Rear Admiral John Ailes, LCS Mission Modules program manager.
The test began by embarking two 30mm guns, mission package software, and associated test equipment and by loading live ammunition. The STF consisted of three live firing scenarios: gun operations, worst case blast loading, and sustained fire. Upon completion of the STF, the surface warfare mission package accomplished multiple tracking exercises May 1 using high speed maneuvering surface targets to simulate both single boat and swarm attacks.
"The STF and initial tracking exercises prepare the ship and train the crews for more complex surface warfare tracking and live fire exercises scheduled to begin summer 2014, which will culminate in initial operational test and evaluation in 2015," said Ailes.
The 30mm gun mission module and a visit boarding search and seizure module are two components of the surface warfare mission package (SUW MP) developed to support the LCS modular concept.
While this was the first 30mm gun firing on an LCS Independence variant, the SUW MP completed deployment to the Western Pacific aboard USS Freedom (LCS 1) in December 2013 and Initial Operational Test and Evaluation aboard USS Fort Worth (LCS 3) in April 2014. The lessons learned and processes developed from the testing aboard Freedom and Fort Worth were critical to the effective and efficient embark, STF, and tracking events aboard Coronado, the second ship of the LCS Independence variant.
PEO LCS is affiliated with the Naval Sea Systems Command and provides a single program executive responsible for acquiring and sustaining mission capabilities of the littoral combat ship class, from procurement through fleet employment and sustainment. The combined capability of the LCS ships and LCS mission systems is designed to dominate the littoral battle space and provide U.S. forces with assured access to coastal areas.

After 10 years of military service, HSV 2 Swift is now available for sale. For more details, please click on brochure at left, or contact Incat Head Office.
History
Built by Incat in Tasmania and delivered in 2003, the 98m Wave Piercing Catamaran HSV 2 Swift was contracted by Military Sealift Command, Washington, DC from Bollinger / Incat USA, LLC, Lockport, Louisiana for the US Navy.
Following successes enjoyed with HSV X1 Joint Venture and TSV 1X Spearhead, High Speed Vessels (HSV) previously acquired through Bollinger/Incat, this third craft was contracted to service operationally as an interim Mine Warfare Command and Support Ship (MCS), and support transformational mine warfare modular payload initiatives.
Capabilities
HSV 2 Swift is capable of maintaining an average speed of 35 knots or greater, loaded with 500 short tons, consisting of 350 personnel and military equipment. A minimum operating range of 1100 nautical miles at 35 knots was required by the contract, as was a minimum transit range of 4000 nautical miles at an average speed of 20 knots. Furthermore, she is capable of 24 hour operations at slow speeds (3-10 knots) for experimentation with unmanned autonomous vehicles, and to support dedicated and emerging organic mine warfare missions.
A stern ramp capable of on/off loading directly astern or to the starboard quarter is fitted. The ramp is capable of loading/unloading a multitude of military vehicles up to and including M1A1 vehicles up to 26,000 lbs, whilst underway. The crane is capable of lifting up to 22,000 lbs to and from the flight deck.
The vessel has a NAVAIR certified helicopter flight deck for operation of MH-60’s, CH-46, UH-1 and AH-1 helicopters. An area protected from the weather for storage and maintenance of two MH-60S is provided to enhance aviation operations in day, night and instrument meteorological conditions.
HSV 2 Swift Milestones
During flight deck certifications, HSV 2 Swift’s crew conducted aircraft recovery while making 43 knots (80km/h) during one recovery and had 66 knots (122km/h) apparent winds during another recovery.
In early 2004 HSV 2 Swift participated in West African Training Cruise 04, an exercise designed to enhance security co-operation between the United States and participating West African nations.
On 03 January 2005 HSV 2 Swift left her homeport of Naval Station Ingleside, Texas to support Operation Unified Assistance, the humanitarian operation in the wake of the Tsunami that struck South East Asia.
During Operation Unified Assistance the crew conducted many firsts for the unique vessel, including 30 straight days at sea, supporting a helicopter detachment and its support crew for 30 days with high tempo flight operations as well as conducting two underway replenishments at sea.
In September 2005, HSV 2 Swift further proved its worth during Hurricane Katrina recovery efforts in New Orleans. The vessel ferried precious relief supplies between Naval Air Station Pensacola and ships deployed throughout the Gulf Coast region stabilising areas affected by the hurricane. HSV 2 Swift’s unique design made the high speed vessel an integral part of the mission by enabling the ship access to depths of less than 12 feet.
Range and Endurance
During July 2006 HSV 2 Swift used her speed, capability and manoeuvrability to delivery repair parts and replenishment items from Manama, Bahrain, to Jebel Ali, United Arab Emirates, for supplying USNS Supply (T-AOE 6) in less than 12 hours.
“That’s one of the things a vessel like Swift can do – rapid delivery of intra-theater cargo,” said HSV 2 Swift Commanding Officer, Cmdr. Rob Morrison. “Supply received its shipment much faster than usual, using less manpower. Streamlining intra-theater deliveries saves the Navy money, man hours and aircraft wear and tear and that made the 98 metre workhorse very popular in the region”.
“With its enormous 28,000 square foot mission deck, the ability to traverse littoral waters, the capability of handling speeds in excess of 40 knots and manoeuvrability that doesn’t require tugboat assistance when arriving or departing the pier, HSV 2 Swift is definitely a multi-tasker”.
Immediately following this impressive display of efficiency HSV 2 Swift was called into play during the Israel-Lebanon conflict, being used to transport humanitarian assistance materials from Cyprus to Beirut.
HSV 2 Swift has since been deployed to the Far East with detachments from US Navy helicopter squadron HSL-37 Mobile Security Squardron 7, and the Second Platoon of the Third US Marine Corps Fast in support of theatre security co-operation efforts in Philippines, Malaysia and Indonesia.
The vessel has been evaluated in risk-mitigation trials in support of the Littoral Combat Ship and JHSV Programs. Sea keeping, structural and propulsion performance were among the qualities evaluated. The vessel also was used to evaluate mission module interfaces for equipment such as the Remote Minehunting System.
The Navy has taken advantage of the lessons learned from HSV 1X Joint Venture and TSV X1 Spearhead. The Bollinger / Incat team incorporated more than 75 enhancements in HSV 2 Swift during construction, and demonstrated unusual flexibility and a strong desire to meet the Navy’s needs. It took only ten months from contract award to ship delivery – record time for putting to sea a truly transformational ship.
As part of their normal working routine, the three Incat vessels HSV 1X Joint Venture, TSV X1 Spearhead. and HSV 2 Swift have serviced the roughest routes in the world on a year round basis; from 65 degrees North Latitude to 45 degrees South Latitude, including conditions as harsh as the Persian Gulf. To date no other HSV in service has yet matched that ability.

USS George Washington completes sea trials, ready for patrol
By Mass Communication Specialist Seaman Apprentice Oscar Albert Moreno Jr.
YOKOSUKA, Japan – The U.S. Navy’s forward-deployed aircraft carrier USS George Washington (CVN 73) returned to its forward-operating location of Fleet Activities Yokosuka, Japan, May 23, after completing sea trials.
Sea trials is a four-day evolution where ships evaluate and assess their equipment status and personnel readiness for follow-on at-sea training.
“Sea trials is without a doubt essential to prepare for a patrol,” said Quartermaster 1st Class Pon Mingkhouan, from Raleigh, N.C. “Sea trials not only allows us to test our equipment, but it also gives new Sailors a taste of what the work days will be like during patrol.”
George Washington completed numerous evolutions during sea trials, including a replenishment-at-sea, refueling-at-sea, man overboard drills, anchor drop test, high-powered turns, aqueous film forming foam counter-measure wash down, and other events.
“We must ensure that the ship and its crew are mission ready,” said Boatswain’s Mate Seaman Joshua Hart, from Calhoun, Ga. “In case of an emergency, we must be ready to respond to whatever happens and whenever it happens.”
With a successful sea trials complete, George Washington makes its final preparations to return to sea for its upcoming 2014 patrol.
George Washington and its embarked air wing, Carrier Air Wing (CVW) 5, provide a combat-ready force that protects and defends the collective maritime interest of the U.S. and its allies and partners in the Indo-Asia-Pacific region.
