US Navy – Hot Hot Hot

Defense Technology InternationalHot Hot Hot

US Navy amphibious ships operating MV-22B Osprey tilt-rotors will need major structural repairs after less than half their planned service lives, according to a newly released Navy document, unless a new Deck Thermal Management System (DTMS) can be developed to protect the decks from exhaust heat. The only other alternative identified so far is a heavy structural modification to the deck. The JSF is considered likely to cause similar problems.

US Navy – USS Texas pays icy visit to Arctic

Honolulu AdvertiserUSS Texas pays icy visit to Arctic

After a dearth of news since it left its base on the East Coast bound for Pearl Harbor, the submarine USS Texas finally resurfaced — near the North Pole. The 7,800-ton attack submarine, with a crew of about 134, last month completed a historic exercise in the Arctic when it became the first of the new Virginia-class submarines not only to operate in the region, but also to surface through the ice.

US Navy – LCS Near Selection

Defense TechLCS Near Selection

Norman Polmar writes that in an attempt to bring order to the Navy’s problem-plagued littoral combat ship (LCS) program, the Navy has announced that it will “down select” a winner from the two LCS designs. The selection, in fiscal year 2010, will determine which design and hence which firms will be responsible for the construction of a planned 51 additional frigate-size warships.

US Navy – Naval Hawks Over Arabian Seas

StrategyPageNaval Hawks Over Arabian Seas

One of the U.S. Navy’s two RQ-4 Global Hawk UAVs recently returned from the Middle East, after a field test of its capabilities. The aircraft made over 60 flights and spent over 1,000 hours in the air. The flights were over land and sea areas, even though the UAV sensors are designed mainly to perform maritime reconnaissance. U.S. Air Force Global Hawk maintenance personnel assisted the navy in tending to the navy RQ-4 while it was on the ground, and for landings and takeoffs. The UAV was operated by navy personnel back in the United States at Patuxent River Naval Air Station. The aircraft was officially called the BAMS-D (Broad Area Maritime Surveillance Demonstrator).

US Navy – Underwater AIM-9X

Defense Technology InternationalUnderwater AIM-9X

In the open ocean, a submarine can be stealthy – by using depth and maneuverability – to avoid air attack. But tactical options have become more limited in littoral operations that require operating in shallow water where evasion is difficult. The new AIM-9X is an air-to-air missile, but with a special underwater shroud (in a combination called the Littoral Warfare Weapon), it can be carried in an unmodified configuration and fired from a submarine’s vertical launch tube.

US Navy – Navy secretary seeks greener fleet

Virginian PilotNavy secretary seeks greener fleet

The secretary of the Navy on Wednesday outlined five energy goals for the Navy and Marines in the next decade. Four involve reducing the consumption of fossil fuels, increasing use of alternative energies and factoring energy costs into the price tag of every new ship, engine or building. The fifth might be the most radical: Mabus committed to fielding by 2012 a “green” strike group composed of aircraft powered by biofuels, surface ships that operate on hybrid power supplies, and nuclear-powered aircraft carriers and submarines.

US Navy – Sea-Based Missiles to Target a Redefined Threat

Wall Street JournalSea-Based Missiles to Target a Redefined Threat

The U.S. plans to deploy sea-based SM-3 interceptor missiles in 2011 as part of its plan to rely on a mix of small, relatively inexpensive defensive systems to counter an evolving Iranian threat.

The White House confirmed Thursday that it would abandon efforts to build a large-scale missile-defense system in Eastern Europe, canceling a program that had become a source of Russian anger. The plan, still in the blueprint stage, would have built a large radar array in the Czech Republic and deployed 10 interceptor missiles to Poland.

Instead, the U.S. plans the SM-3 deployment, followed by a more advanced version of the system in 2015 that would include defensive missiles that could be launched from both sea and land.
