– AFP – The US military has failed to prepare a realistic “plan B” if political turmoil forces the closure of a vital naval base in Bahrain, a naval officer argues in a report.

– US Naval Institute Proceedings – The 3D printing revolution will radically change naval construction and logistics.

– US Naval Institute Proceedings – Deep yet pragmatic cooperation with our allies and partners could bring surprising strategic benefits—even under fiscal austerity.

– Air Force – The air and maritime concept is maturing, but must fight off interservice rivalries and Pentagon politics.

– US Naval Institute Proceedings – Littorals are increasingly dangerous to naval forces. The proliferation of sophisticated shore- and ship-launched antiship missiles, asymmetric tactics such as the fast-boat swarm, and sophisticated anti-access/area denial technologies, makes these areas more difficult to penetrate and dominate. Though few groups or nations can challenge or threaten the U.S. Navy on or below blue water, the risks presented today to our manned warships by the green and brown waters of the world are neither negligible nor cheap to mitigate.

– Breaking Defense – Like the Holy Trinity or the designated hitter rule, the concept known as AirSea Battle has been much discussed but little understood. The Defense Department released an official and unclassified summary of the concept for the first time this evening on a Navy website . AirSea Battle would break down longstanding barriers: barriers to cooperation among the four armed services, barriers separating domains of conflict like submarine warfare and cyberspace, and, most problematically, barriers that have kept past crises from escalating to greater destruction and even, ultimately, to nuclear war.

– US Naval Institute Proceedings – Here are steps the U.S. Navy must take to realize the vision of autonomous systems.

– DefenseTech – The Pentagon’s Missile Defense Agency and the U.S. Navy are developing next-generation Aegis ballistic missile defense (BMD) hardware and software along with a longer-range interceptor missile engineered to massively increase the protective envelope against intermediate and long-range ballistic missile threats, service officials said.

– Virginian Pilot – The USS Stethem is one of two warships in the western Pacific that are responsible for detecting, tracking and, if necessary, shooting down a ballistic missile launched by Pyongyang. And they represent the first line of defense for U.S. allies and territories in a region that has become increasingly nervous as North Korea has ratcheted up its rhetoric and threats in recent months.

– Aviation Week – It’s often said that the past is prologue and U.S Navy Secretary Ray Mabus recently highlighted that sentiment when he visited Singapore to help trumpet the arrival there of the Littoral Combat Ship (LCS-1) USS Freedom and the importance of the U.S. Pacific pivot.

– Aviation Week – The Freedom never had to endure a hurricane on the way to Singapore, but the ship certainly has gone through a tempestuous set of trials and tribulations. During transit, the ship suffered a series of power outages, and once in Singapore the Freedom was sidelined by a coolant leak that also apparently cut short the ship’s initial extended underway.

– Breaking Defense – An aircraft carrier is nothing without aircraft, and a Navy aircraft is worth little without a carrier. It’s ships and planes in synergy that revolutionized war at sea in the 1930s and with new systems now entering service – the F-35C Joint Strike Fighter and the Ford-class carrier – they can do it again. On April 30, we sat down with Rear Admiral Bill Moran, the Director of Air Warfare on the Navy staff (OPNAV N98) and co-author of a recent article on future carriers, to discuss the transition to the Ford and JSF. While the new carrier can still perform its traditional role as the centerpiece of a mobile island of concentrated naval force, Moran said, the Ford class, the evolving air wing, and an array of other new capabilities will allow the carrier to play a much more flexible and distributed role.

– National Defense – As the U.S. military turns its attention to the Pacific, Navy Sea-Air-Land (SEAL) teams are already undergoing a transition back to their maritime roots, said Rear Adm. Sean Pybus, commander of Navy Special Warfare.

– Reuters – If it works, the X-47B and follow-on drones, which are devised to be armed with bombs and missiles, could nearly quadruple the striking range of the United States’ 10 nuclear-powered aircraft carriers – reversing a recent decline in the giant ships’ ability to do battle against a determined, high-tech foe…Namely, China.

– Breaking Defense – Just nine months after hosting the biggest multinational mine-warfare exercises “ever” to be held in and around the Persian Gulf, the Navy’s 5th Fleet and its foreign partners outdid themselves with a second, even larger wargame. More than 20 nations participated in September’s International Mine Counter-Measures Exercise 2012, collaborating against fictional ecoterrorists whose capabilities were suspiciously similar to the real-world arsenal of Iran. This month, 41 nations and some private-sector companies participated in IMCMEX 2013, which despite the name expanded beyond minesweeping to practice protecting civilian oil tankers, oil rigs, ports, and even desalinization plants as well.

– Wired – America’s ship-launched X-47B killer drone prototype took off for the first time from the aircraft carrier USS George H.W. Bush sailing near the Maryland coast on Tuesday morning — the first step in proving that a high-performance Unmanned Aerial Vehicle is compatible with the Navy’s fleet of 10 gigantic nuclear-powered flattops. But that doesn’t mean the sailing branch will definitely be purchasing similar jet-powered drones for frontline use. According to Bob Work, until recently the Navy undersecretary and a big supporter of armed UAVs, the sea service must choose between X-47B-style ‘bots and a simpler, propeller-driven drone similar to the Air Force’s Predator.

– Breaking Defense – Unmanned aircraft are relatively easy to fly. Landing one without crashing is hard. Getting one to take off from the narrow, pitching deck of an aircraft carrier is harder still. Landing on a carrier? That’s hard enough to give human pilots nervous breakdowns. Soon, it will be the final test of the Navy’s prototype carrier-based drone, the X-47B.

– Wired – At 11:19 a.m. today, for the first time in history, a plane without a pilot in it executed one of the most complex missions in aviation: launching off an aircraft carrier at sea. Only the Navy can’t yet land that drone aboard the U.S.S. George H.W. Bush, an even harder but necessary maneuver if large drones are really going to operate off carriers.

– Aviation Week – The U.S. Navy gets set this month to essentially – if unofficially – christen its “Pacific pivot” with a coming-out party of sorts for the Littoral Combat Ship (LCS-1) USS Freedom at the Imdex Maritime Defense Show in Singapore.

– Time – The U.S. Navy routinely says it needs more ships. One way it makes that need more dire is by retiring existing vessels well before their planned lifespan is over. Think of it as fleethanasia.

– BBC – The US Navy has launched a squadron combining unmanned drones as well as manned aircraft, amid a national debate over the role of drones in warfare.

– AOL Defense – Navy Secretary Ray Mabus talked up the controversial Littoral Combat Ship days before departing for Asia to visit the first LCS, USS Freedom, which recently arrived in Singapore (sporting a sniffy camo paint job). Freedom has been bedeviled by cost overruns, delays, and manufacturing defects, with a new problem, seawater contamination in lubricant fluid, arising on its trans-Pacific trip. But the bigger picture Mabus said, is how this new class of small and nimble ship will cooperate with foreign partners to keep the peace in the volatile South China Sea and the strategic Strait of Malacca.

– Aviation Week – Some lawmakers would like nothing better than to see U.S. Navy Secretary Ray Mabus unplugged – but the nation’s top naval leader will have none of that. He’s pushing for his energy-altering programs with a doggedness that would even tire out the Energizer Bunny.

– AOL Defense – What homemade roadside bombs could do to Army and Marine ground vehicles was the ugly surprise of the last decade. What sophisticated long-range missiles could do to Navy aircraft carriers could be the ugly surprise of the next.
