USN completes first Spike precision engagement firings from USV By Richard Scott 11/5/2012 The US Navy (USN) has performed the first live firings of a Rafael Spike long-range (LR) missile from a remotely operated precision engagement module (PEM) developed for unmanned surface vehicle (USV) applications.
Performed in late October, the proof-of-concept demonstration is believed to mark the first time that the USN has launched a guided weapon from a USV.
Combining a Rafael Mk 49 Mod 0 Remote Operated Small Arms Mount (ROSAM) 0.5 calibre machine gun and a dual Spike LR missile pannier, the PEM module has been developed by the Chief of Naval Operations' Expeditionary Warfare Division and the US Naval Sea Systems Command's (NAVSEA's) Special Warfare Program Office. The remote operator uses onboard sensors to obtain and track targets, and can then engage close-in targets with the ROSAM mount, or use the missile's sensors to lock onto targets outside effective small arms range. The Spike LR missile, combining electro-optic and infrared sensors with wire-guidance for operator in-the-loop control, has a 4 km range and the ability to lock-on before or after launch.

Raytheon awarded US Navy contract for Ship Self-Defense System
Extending open architecture combat system deployment and fleet support
TEWKSBURY, Mass., Nov. 5, 2012 /PRNewswire/ -- Raytheon Company (NYSE: RTN) has been awarded a $22.5 million U.S. Navy contract for the Ship Self-Defense System. With this award, Raytheon will continue system development, test and integration, as well as Platform Systems Engineering Agent (PSEA) services and support for fleet-deployed systems.
SSDS is an open, distributed combat management system in service on carriers and amphibious ships, including CVN, LSD dock landing ship, LPD, LHA and LHD classes. The LHA variant is nearing initial deployment, a technical refresh of the LSD-class is almost complete, and system development is underway for the new CVN 78-class of aircraft carriers. SSDS is designed to expedite the detect-to-engage sequence to defend against anti-ship cruise missiles. The system integrates and automates standalone sensors and weapon systems to provide the required, quick response and multi-target engagement capability.
"SSDS is a deployed and proven combat management system, delivering outstanding capabilities and performance as well as the reliability, refresh and the inherent interoperability benefits of an open architecture design," said Kevin Peppe, vice president of Seapower Capability Systems for Raytheon's Integrated Defense Systems business. "The evolution of SSDS -- spanning decades, ship classes, sensors and weapons systems -- demonstrates Raytheon's ability to deliver innovation in a platform-agnostic approach for all major naval surface platforms."
In addition to the contract, the Navy has announced its intent to increase the current PSEA contract ceiling by $50 million to extend SSDS services and support through its Fiscal Year 2013. Raytheon has been the SSDS PSEA since 2008, providing ongoing maintenance, upgrades and lifecycle support for both new ship programs as well as legacy ships. As PSEA, Raytheon has achieved consistently favorable customer performance ratings over the life of the contract.

Boeing delivered the fifth production P-8A Poseidon to the U.S. Navy.
SEATTLE, Nov. 5, 2012 -- Boeing [NYSE: BA] on Nov. 2 delivered the fifth production P-8A Poseidon aircraft to the U.S. Navy. The P-8A is one of 24 low-rate initial production (LRIP) maritime patrol aircraft that Boeing is building for the Navy as part of contracts awarded in 2011 and 2012.
"This is our final P-8A delivery of the year; we’ll ramp up to 12 deliveries, including P-8I aircraft for India, in 2013," said Chuck Dabundo, Boeing vice president and P-8 program manager. "Our in-line production approach, which draws on processes developed on the company's commercial and military programs, has been key to our ability to increase production rates while reducing costs."
"As we transition to the P-8A and prepare for Initial Operational Capability in 2013, the U.S. Navy is successfully flying the first production planes at Naval Air Station Jacksonville, Fla.," said Capt. Aaron Rondeau, U.S. Navy P-8A Integrated Product Team lead.
The next three Poseidon aircraft are undergoing mission systems installation and checkout in Seattle, and two more are in final assembly in Renton, Wash. Boeing will deliver its sixth production P-8A to the Navy in early 2013.
The Navy plans to purchase 117 of the Boeing 737-based P-8A anti-submarine warfare, anti-surface warfare, intelligence, surveillance and reconnaissance aircraft to replace its P-3 fleet.
As part of the LRIP contracts, Boeing is also providing aircrew and maintenance training for the Navy, in addition to logistics support, spares, support equipment and tools.

L-3 delivers refurbished P-3C Orion back to US Navy
L-3 has delivered its first refurbished Lockheed Martin P-3C Orion maritime patrol aircraft back to the US Navy under the sustainment, modification and installation programme (SMIP).
L-3 preforms SMIP work on all variants of the Orion airframe, 147 of which are still in service, for the USN, the company says. That includes P-3 outer wing refurbishment, P-3 outer wing installation, special structural inspection kits, phased maintenance inspections and modification/installation programs.
The company says it will only get better over time in refurbishing the ageing four-engined turboprop.
"We are committed to continuous improvement, and we know that accelerating the turnaround time in such a dramatic way reduces the cost of sustainment and increases the operational availability of the aircraft to the warfighter," says Nick Farah, executive vice president of L-3 Platform Systems.
L-3 was first awarded the SMIP contract in 201, the indefinite-delivery, indefinite-quantity programme is a follow-on to a similar contract awarded to L-3 in 2005.

Nation’s Seventh Littoral Combat Ship Takes Shape as Lockheed Martin Team Lays the Keel
MARINETTE, Wis., Nov. 8, 2012 – A Lockheed Martin [NYSE: LMT]-led industry team officially laid the keel for the U.S. Navy’s seventh Littoral Combat Ship (LCS), the future USS Detroit. The event was part of a time-honored keel laying ceremony that took place at the Marinette Marine Corporation shipyard in Wisconsin.
The Lockheed Martin LCS team is building the futuristic Freedom-variant LCS for the U.S. naval fleet. With the first two ships delivered, two additional ships in production and two more in early material procurement, the industry team is addressing the Navy’s need for an affordable, highly-networked and modular ship unlike any other in the world. This new class of combatants is designed to support a wide variety of missions including anti-submarine, surface and mine countermeasure warfare, shipping lane protection, and humanitarian aid.
“It’s an honor to participate in this event for the future USS Detroit,” said Sen. Carl Levin, D-Mich. “The keel laying ceremony marks a great milestone for the program and the naval fleet. These ships are vital to our national defense strategy and their production contributes significantly to the Wisconsin and Michigan economies.”
During the ceremony ship sponsor Barbara Levin authenticated the keel by having her initials welded into a sheet of the ship’s steel. She was assisted by the Navy’s Program Executive Officer – Littoral Combat Ships Rear Admiral James Murdoch.
“This ceremony marks the beginning of my commitment to supporting the future USS Detroit and the brave crews that will serve aboard her to defend our country,” said Barbara Levin. "It is a very moving moment for me, as I am very proud to serve as the sponsor of this powerful ship which honors my native city."
The Lockheed Martin-led LCS team includes ship builder Marinette Marine Corporation, a Fincantieri company, naval architect Gibbs & Cox, as well as hundreds of domestic and international suppliers, including approximately 30 small businesses in Wisconsin and Michigan.
“Marinette Marine Corporation’s shipbuilding expertise, coupled with Lockheed Martin’s integrated and automated systems that bring the capability to fight, operate and support the ship, make the Freedom-variant LCS a powerful vessel,” said Joe North, vice president of Littoral Ship Systems for Lockheed Martin’s Mission Systems & Sensors business. “The LCS team continues to invest in shipyard improvements and has applied best practices to ensure we continue to be more efficient and more innovative with each new ship we build.”
By 2013, industry investment will total approximately $94 million, which includes nearly $70 million to date from Marinette Marine Corporation's Italian parent Fincantieri-Cantieri Navali Italiani for shipyard improvements.
Lay the keel is a shipbuilding term that marks the beginning of the module erection process, which is a significant undertaking that signifies the ship coming to life. Modern warships are now largely built in a series of pre-fabricated, complete hull sections rather than a single keel, so the actual start of the shipbuilding process is now considered to be when the first module for the ship is erected in place and is often marked with a ceremonial event.

US Navy, Raytheon receive Pentagon engineering award for GPS-guided precision landing program
Risk mitigation, cost and schedule targets cited
MARLBOROUGH, Mass., Nov. 15, 2012 /PRNewswire/ -- A U.S. Navy program that uses Raytheon Company (NYSE: RTN) technology to land aircraft in harsh weather has been recognized with a Department of Defense engineering award.
The Joint Precision Approach and Landing System (JPALS) Increment 1A ship system received the Systems Engineering Top 5 Programs Award for "successful implementation of systems engineering best practices resulting in program success," according to the Department's announcement.
JPALS uses the Global Positioning System and two-way data links for precise area navigation and landing approaches for Navy carrier-based aircraft and helicopters.
The U.S. Navy-Raytheon team "utilized solid systems engineering practices to manage requirements, identify and mitigate risk, and manage the technical baseline, while keeping the program within cost and schedule targets," according to the evaluation team. An award ceremony was held Oct. 24, 2012, in San Diego, Calif., sponsored by the National Defense Industrial Association.
Raytheon is currently installing JPALS on the aircraft carrier George H.W. Bush, CVN-77. Government integration of the system with other ship systems was completed in the Navy's test facility, and flight testing commenced in May 2012. Shipboard testing on the carrier is planned to start as early as December. Raytheon completed development activities on time -- including delivery of eight ship system engineering development models and five avionics test kits on or ahead of schedule.

Vigor Marine to deliver MLP core capability set By Richard Scott 11/20/2012 Portland, Oregon-based ship repair group Vigor Marine has been selected by the US Naval Sea Systems Command (NAVSEA) to design, build, and integrate the Core Capability Set (CCS) equipping the US Navy's (USN's) three new Mobile Landing Platform (MLP) float-on/float-off (flo-flo) sea-basing support vessels.
NAVSEA awarded the company a USD35 million firm fixed-price contract for CCS detail design, construction, installation, and systems verification on 16 November.
The CCS is a suite of mission components that can be installed and removed from the mission deck – extending from the forecastle to the deckhouse and spanning the width of the vessel – of an MLP ship. Its function is to enable the transfer of vehicles and equipment at-sea from Large Medium-Speed Ro-Ro (LMSR) ships, and to interface with surface connector craft, including the Landing Craft Air-Cushion (LCAC), the Joint High Speed Vessel (JHSV), and the Improved Navy Lighterage System, which can then deliver vehicles and materiel ashore.
Part of the USN's Maritime Prepositioning Force (Future), and described as a 'sea base surface interface hub', the MLP is in essence an at-sea transfer station that will enable cargo to be transferred from LMSRs to landing craft. http://www.janes.com/products/janes/defence-security-report.aspx?ID=1065973579&channel=defence

Navy: Aircraft carrier presence in the Persian Gulf area to drop from two to one
In this Nov. 12, 2011, photo provided by the U.S. Navy, the Nimitz-class aircraft carrier USS John C. Stennis (CVN 74) transits the Straits of Hormuz.AP Photo/U.S. Navy, Petty Officer 3rd Class Kenneth Abbate, FileWASHINGTON -- The Navy said Wednesday it will temporarily shrink its aircraft carrier presence in the Persian Gulf area from two to one because of a mechanical problem with the USS Nimitz, a carrier based in Everett, Wash.
The Nimitz was scheduled to deploy in January to relieve the USS Dwight D. Eisenhower, but that will be put off until summer in order to complete repairs to its propulsion system.
The problem was discovered while the ship was doing pre-deployment maneuvers.
As a result, the Navy made the unusual decision to bring the Eisenhower home to Norfolk, Va., in December and resurface its flight deck so it can go back to the Gulf area in February and remain for four months. That means that in December and January the USS John C. Stennis will be the only carrier in that area, although there are other naval forces there, including Marines aboard a three-ship contingent led by the USS Peleliu.
In announcing the moves, the Navy said none are related to the conflict between Israel and the Hamas militants in Gaza -- or any other security threats or contingency planning. They said it reflects wear and tear on the carrier fleet, which has been under enormous strain during more than 11 years of war.
The decision to leave a two-month gap in the normal two-carrier Navy presence was approved Tuesday by Defense Secretary Leon Panetta, officials said. The carriers are a key feature of the U.S. military strategy for the Mideast.
This will be the first such gap in the Gulf region since at least December 2010, the Navy said.
The Stennis, which deployed from its home port of Bremerton in late August, is due to head home in March. The current plan calls for it to be replaced then by the USS Harry S Truman.

Le drone de combat X-47B à bord de l’USS Harry S. Truman 27/11/2012
crédits : NORTHROP GRUMMAN
Le premier drone de combat spécialement conçu pour être mis en œuvre depuis un porte-avions a embarqué dimanche, à Norfolk, sur l’USS Harry S. Truman. Développé par Northrop Grumman dans le cadre du programme UCAS-D, le démonstrateur X-47B a été gruté sur le porte-avions américain afin de réaliser une première campagne de tests à bord d’un bâtiment de ce type. C’est le 4 février 2011 que cet engin de type UCAS (Unmanned Combat Air System) ou UCAV (Unmanned Combat Air Vehicle) a réalisé son premier vol depuis la base aérienne d’Edwards, en Californie. Depuis, de nombreux essais ont été réalisés avec ce drone, qui a été transporté par barge depuis la base aéronavale de Patuxent River jusqu’à Norfolk.
A bord de l’USS Harry S. Truman, le X-47B subira différents tests, l’objectif de cette campagne étant de valider son intégration dans les opérations de pont d’envol. Durant les essais, le X-47B sera télé-opéré via un système de commande portatif. D’autres campagnes d’essais sont ensuite prévues avant que l’engin ne s’envole et apponte pour la première fois d’un porte-avions, ce qui est prévu au plus tôt l’an prochain.
Long de 11.6 mètres pour une envergure de 18.9 mètres (supérieure à celle du F/A-18 Super Hornet), le X-47B présente une masse maximale de plus de 20 tonnes et une autonomie supérieure à 2000 nautiques. Pouvant opérer à 40.000 pieds, il dispose d’un moteur Pratt&Whitney, sa vitesse de croisière étant de Mach 0.45. Cet engin furtif est conçu pour embarquer deux bombes de 900 kilos, logées dans des soutes spécifiques.
Lancé en 2005, le programme UCAS-D, qui a vu le démonstrateur de Northrop Grumman retenu par l’US Navy en 2007, vise à acquérir une capacité technologique et opérationnelle dans le cadre du développement futur d’engins de combats non pilotés embarqués sur porte-avions.

BAE Systems Receives $80 Million U.S. Navy Contract for Two Advanced Gun Systems
Advanced Gun System (AGS)
BAE Systems has received an $80.3 million modification contract award from the U.S. Navy to deliver two Advanced Gun Systems (AGS) for the latest in the Zumwalt class destroyer fleet, the DDG 1002.
This contract marks the third destroyer to receive AGS applications and brings the total funding of the initial contract for this ship, first awarded in October 2011, to $149 million.
“This contract demonstrates the progress made on the DDG 1000 program with the integration of AGS technology onto now a third DDG 1000 destroyer,” said Dave Johnson, director of the DDG 1000 program for BAE Systems. “The AGS is critical in supporting the U.S. Navy and Marine Corps’ expeditionary and joint operations against a wide range of littoral and deep inland targets.”
The AGS is a 155mm, vertically loaded gun mount that is capable of storing, programming and firing the Long Range Land Attack Projectile (LRLAP). It is a fully automated weapon system that can fire 10 rounds per minute with ranges greater than 60 nautical miles.
The AGS rounds are drawn from a fully-automated, below-deck weapon handling and storage system holding up to 300 rounds. By eliminating the need for personnel in the magazine, the AGS design supports the U.S. Navy's goals to significantly reduce overall crew requirements and increase crew safety.
To date, BAE Systems has designed, built and integrated four AGS for the first two DDG 1000 destroyers in the Zumwalt class fleet. Work under this contract will be performed at BAE Systems’ Louisville, Kentucky and Cordova, Alabama facilities, and is expected to be completed by January 2018.

Sikorsky, Boeing eye US Navy's draft solicitation for presidential helicopter replacement programme By Grace Jean 11/29/2012 The US Naval Air Systems Command's (NAVAIR) release of a draft solicitation for the US Presidential Helicopter Replacement Program (VXX) has caught the attention of two defence contractors seeking to make a successful bid to build the aircraft.
Sikorsky, the builder of the current fleet of VH-3D Sea King and VH-60N Black Hawk presidential helicopters, and Boeing, the manufacturer of the CH-47 Chinook and the MV-22 Osprey in partnership with Bell Helicopter, are eyeing the VXX draft request for proposal (RfP) issued on 23 November. The RfP sets forth design criteria and requirements for a low-cost vertical-lift platform that will replace the VH-3D and VH-60N helicopters, which have been in service since the 1960s and the 1980s, respectively.
The navy is seeking to buy as many as 23 operational VXX helicopters, which will be flown by the US Marine Corps' Marine Helicopter Squadron One (HMX-1) based at Quantico, Virginia. The rotorcraft would enter service in 2020, more than a decade later than the programme originally intended.
The US government is encouraging offerors to propose an existing, in-production helicopter platform in order to minimise aircraft development on the VXX programme.

US national debt, fiscal uncertainty threaten navy's operational future By Grace Jean 11/30/2012 The US Navy faces an array of fiscal challenges that will require its leaders to make tough decisions in order to fulfill combatant commanders' demands in the coming years, the service's chief resourcing official said on 27 November.
Vice Admiral John T. Blake, deputy chief of naval operations for integration of capabilities and resources (N8), said that, while the current fiscal crisis causes great consternation for him, it is the US national debt that keeps him up at night.
"We're having debates about fiscal realities but no one is discussing the fact that the debt ceiling is encroaching and rapidly approaching, and we're going to have to do something about that," Adm Blake said during a Surface Navy Association event near Washington, DC. "If we do nothing, I don't see how the N8s of the world are going to be able to deal with that, and still meet the requirements we have worldwide."
The Congressional Budget Office has estimated that the national debt could equal 100% of the US GDP by 2020. Federal debt held by the public reached 73% of the GDP in Fiscal Year 2012 (FY12), which ended 30 September.

USS Enterprise carrier taken out of active service
NORFOLK, Va. -- The world's first nuclear-powered aircraft carrier was retired from active service on Saturday, temporarily reducing the number of carriers in the U.S. fleet to 10 until 2015.
The USS Enterprise ended its notable 51-year career during a ceremony at its home port at Naval Station Norfolk, where thousands of former crew members, ship builders and their families lined a pier to bid farewell to one of the most decorated ships in the Navy.
"It'll be a special memory. The tour yesterday was a highlight of the last 20 years of my life. I've missed the Enterprise since every day I walked off of it," said Kirk McDonnell, a former interior communications electrician aboard the ship from 1983 to 1987 who now lives in Highmore, S.D.
The Enterprise was the largest ship in the world at the time it was built, inheriting the nickname "Big E" from a famed World War II aircraft carrier. It didn't have to carry conventional fuel tanks for propulsion, allowing it to carry twice as much aircraft fuel and ordnance than conventional carriers at the time. Using nuclear reactors also allowed the ship to set speed records and stay out to sea during a deployment without ever having to refuel, one of the times ships are most vulnerable to attack.
"Nuclear propulsion changed everything," said Adm. John Richardson, director of Naval Reactors.
Every other aircraft carrier in the U.S. fleet is now nuclear-powered, although they only have two nuclear reactors each compared to the Enterprise's eight. The Enterprise was the only carrier of its class ever built.
It was only designed to last 25 years, but underwent a series of upgrades to extend its life, making it the oldest active combat vessel in the fleet
The ship served in every major conflict since participating in a blockade during the Cuban Missile Crisis, helping earn its motto of "We are Legend."
Enterprise was headed back to Virginia following a regularly scheduled deployment when the Sept. 11 attacks happened. As soon as the ship's captain saw the attacks he turned around without orders to steam toward southwest Asia, where it later launched some of the first attacks against Afghanistan. The ship's captain was Adm. James A. Winnefeld, who now serves as the vice chairman of the Joint Chiefs of Staff.
It has been returning to that region of the world ever since then, including during its 25th and final deployment that ended last month.
"She just served on the cutting edge at the tip of the spear when she returned here in November," Chief of Naval Operations Jonathan Greenert said. "It's shown that the aircraft carrier can evolve as a platform with many payloads relevant for five decades and will be part of our national security for the foreseeable future as we bring on the Gerald Ford to replace the Enterprise."
The Gerald R. Ford will be the first of a new class of aircraft carriers, but it will be several more years before it joins the fleet. Temporarily reducing the number of aircraft carriers to 10 required special congressional approval.
Chief of Naval Operations Adm. Jonathan Greenert said the Navy would closely watch how the increased operational tempo will affect sailors. In February, the USS Abraham Lincoln will begin a four-year refueling complex overhaul in Newport News, Va., which will also take it out of rotation.
Greenert said the Navy wants to continue having two aircraft carriers operating simultaneously in the Middle East through March, but he said he wasn't sure if that would continue past then.
While the Enterprise was inactivated Saturday, it will be several more years before it is fully decommissioned. Its nuclear fuel must first be removed by punching gigantic holes in the ship, rendering it unfit for service or turning it into a museum. It will eventually be towed to Washington state for scrapping.
The nuclear-powered aircraft carrier was the eighth U.S. ship to bear the name Enterprise, but it won't be the last. Navy Secretary Ray Mabus said in a video message that a future aircraft carrier would be named USS Enterprise, after the delivery of the USS Gerald R. Ford and the USS John F. Kennedy.
Mabus' announcement drew a standing ovation from those on hand at Saturday's ceremony. Current and former crew members have lobbied heavily to preserve Enterprise's name so its legacy will live on.
"It just seems to be a neat name for a ship. It's better than being named for a politician," said Larry Kosnopfal, one of the ship's original crew members, who now lives in Chadfield, Minn.
When the future USS Enterprise joins the fleet, its commanding officer will be handed a 200-pound time capsule filled with Enterprise memorabilia that includes notes from sailors, insignia and small pieces of the ship. The time capsule was delivered to Greenert for safekeeping until that future commanding officer is chosen.

Navy: No U.S. drones missing after Iran claim
By Ali Akbar Dareini and Brian Murphy - The Associated Press Posted : Tuesday Dec 4, 2012 6:03:23 EST
TEHRAN, Iran — Iran claimed Tuesday it had captured a U.S. drone after it entered Iranian airspace over the Persian Gulf— even showing an image of a purportedly downed craft on state TV — but the U.S. Navy said all its unmanned aircraft in the region were “fully accounted for.”
The conflicting accounts leave the possibility that the drone claimed by Iran, a Boeing-designed ScanEagle, could have been plucked from the sea in the past and unveiled for maximum effect following escalating tensions over U.S. surveillance missions in the Gulf.
Other countries in the region — such as the United Arab Emirates — also have ScanEagle drones in their fleets.
Cmdr. Jason Salata, a spokesman for the U.S. Navy’s 5th Fleet in Bahrain, said ScanEagles operated by the Navy “have been lost into the water” over the years, but there is no “record of that occurring most recently.”
The Iranian announcement did not give details on the time or location of the claimed drone capture.
It’s certain, however, to be portrayed by Tehran as another bold challenge to U.S. reconnaissance efforts in the region. Last month, the Pentagon said a drone came under Iranian fire in the Gulf but was not harmed. A year ago, Iran managed to bring down an unmanned CIA spy drone possibly coming from Afghanistan.
“The U.S. Navy has fully accounted for all unmanned air vehicles operating in the Middle East region,” said Salata. “Our operations in the Gulf are confined to internationally recognized waters and airspace.”
Iran claimed it captured the drone after it entered Iranian airspace. A report on state TV quoted the navy chief of Iran’s powerful Revolutionary Guard, Gen. Ali Fadavi, as saying the Iranian forces caught the “intruding” drone, which had apparently taken off from a U.S. aircraft carrier.
“The U.S. drone, which was conducting a reconnaissance flight and gathering data over the Persian Gulf in the past few days, was captured by the Guard’s navy air defense unit as soon as it entered Iranian airspace,” Fadavi said. “Such drones usually take off from large warships.”
Al-Alam, the Iranian state TV’s Arabic-language channel, showed two Guard commanders examining what appeared to be an intact ScanEagle drone. It was not immediately clear if that was the same drone Iran claimed to have captured.
In the footage, the two men then point to a huge map of the Persian Gulf in the background, showing the drone’s alleged path of entry into Iranian airspace.
“We shall trample on the U.S,” was printed over the map, next to the Guard’s coat-of-arms.
If true, the seizure of the drone would be the third reported incident involving Iran and U.S. drones in the past two years.
Last month, Iran claimed that a U.S. drone had violated its airspace. The Pentagon said the unmanned aircraft came under fire — at least twice but was not hit — and that the Predator was over international waters.
The Nov. 1 shooting in the Gulf was unprecedented and further escalated tensions between the United States and Iran, which is under international sanctions over its suspected nuclear program. Tehran denies it’s pursuing a nuclear weapon and insists its program is for peaceful purposes only.
In late 2011, Iran claimed it brought down a CIA spy drone after it entered Iranian airspace from its eastern borders with Afghanistan and Pakistan. The RQ-170 Sentinel drone, which is equipped with stealth technology, was captured almost intact. Tehran later said it recovered data from the top-secret drone.
In the case of the Sentinel, after initially saying only that a drone had been lost near the Afghan-Iran border, American officials eventually confirmed it had been monitoring Iran’s military and nuclear facilities. Washington asked for it back but Iran refused and instead released photos of Iranian officials studying the aircraft.
The U.S and its allies believe Iran is pursuing a nuclear weapon. Iran denies the charge, saying its nuclear activities are for peaceful purposes only, such as power generation and cancer treatment.
Iran, meanwhile, has claimed advances in drone technology.
In November, Iranian media reported that the country had produced a domestically made drone capable of hovering. Earlier, Iran said it obtained images of sensitive Israeli bases taken by a drone that was launched by Lebanon’s Hezbollah and downed by Israel.
Iran also claimed other drones made dozens of apparently undetected flights into Israeli airspace from Lebanon in recent years. Israel has rejected the Iranian assertions.
Murphy reported from Dubai, United Arab Emirates.

USA. Keel laid for future USNS John Glenn
Thursday, 06 December 2012
General Dynamics NASSCO held a keel laying ceremony for the future USNS John Glenn (MLP 2), in San Diego, Calif.
MLP 2 is the second ship in the Mobile Landing Platform program that will provide the Navy with the capability to transfer vehicles and equipment at sea and to interface with surface connectors to deliver the vehicles and equipment ashore.
The ship's name honors the Hon. John Glenn, a decorated Marine Corps pilot, who was in attendance for the ceremony. A distinguished astronaut, the first American to orbit the Earth and a former U.S. Senator from Ohio, Glenn flew 59 combat missions during his service with the Marine Corps in World War II, and a combined 90 missions over the course of two tours in the Korean War.
"It is fitting that this ship is named in honor of a transformative figure like Senator John Glenn," said Capt. Henry Stevens, Strategic Sealift and Theater Sealift program manager, Program Executive Office, Ships. "MLP will be the centerpiece of the Navy's seabasing capability and transform how the Navy and Marine Corps team operates from the sea."
Keel laying recognizes the first joining together of a ship's components. While modern shipbuilding processes allow fabrication of individual modules to begin months earlier, keel laying represents the formal beginning of a ship. The keel was co-authenticated by Lyn Glenn, ship's sponsor, and Helen Toolan, spouse of Lieutenant General John A. Toolan, Jr., USMC, Commanding General I Marine Expeditionary Force.
Acting as a mobile seabase, MLP will be part of the critical access infrastructure that supports the deployment of forces and supplies to provide prepositioned equipment and supplies with flexible distribution. MLPs are based on an existing commercial NASSCO design, the Alaska-class crude oil carrier, ensuring design stability and lower development costs. MLP will have a maximum speed of 15 knots and range of 9500 nautical miles. At 837 feet long, MLP displaces over 80,000 tons when loaded. The ship with its modular core capability set includes a 25,000 sq. ft. raised vehicle deck, side-port ramp, large mooring fenders, and berths for up to three Landing Craft Air Cushioned vessels (LCAC).
These ships serve as a highly flexible, modular platform that may be used across a broad range of military operations, including humanitarian support and sustainment of traditional military missions. They will operate within Maritime Prepositioning Ship Squadrons to The ability to establish support facilities at sea assures U.S. military forces access to areas previously denied.
The USNS Montford Point (MLP 1), lead ship of the class, launched Nov. 13. MLP 2 is expected to launch and be christened in Fall 2013. The contract for the third ship, the future USNS Lewis Puller, was awarded to NASSCO in February 2012.
As one of the Defense Department'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. Currently, the majority of shipbuilding programs managed by PEO Ships are benefiting from serial production efficiencies, which are critical to delivering ships on cost and schedule.
