Independence-variant Littoral Combat Ship Coronado (LCS 4) successfully completed Acceptance Trials (AT) on August 23, 2013, in the Gulf of Mexico. This milestone achievement involved the execution of intense comprehensive tests by the Navy while underway, which demonstrated the successful operation of the ship’s major systems and equipment. This is the last significant milestone before delivery of the ship, which is expected in September.
The Littoral Combat Ship (LCS) is a fast, agile, focused-mission platform designed for operation in near-shore environments yet capable of open-ocean operation. This vessel is the second of twelve, 127-meter Independence-variant LCS class ships Austal has been contracted to build for the U.S. Navy (including USS Independence (LCS 2), delivered to the Navy in 2009). The final 10 of the 12 were awarded to Austal as prime contractor subsequent to a $3.5 billion block buy in 2010.
Austal’s teaming partner, General Dynamics Advanc... [More]
Development of a mini-water jet propulsion system with a diameter of just 100 millimetres to quietly propel an unmanned surface craft on remotely controlled intelligence, surveillance and reconnaissance missions, is the daunting challenge to be tackled by Rolls-Royce as they participate in a US Government funded project led by Candent Technologies Inc.

Candent Technologies, based in Greenfield, Indiana, was selected for the award of a Small Business Innovative Research (SBIR) Phase I contract from the U.S. Navy. This Phase I program of the contract is the first step in the development of a high efficiency heavy fuel propulsion system for a small surface unmanned craft (volatile fuels like gasoline, hydrogen, propane, or methanol not permitted).The project, known as MUSCL (the US Navy’s Modular Unmanned Surface Craft Littoral) is to develop an X-class unmanned surface vessel, whose purpose is to reduce risk to manned forces and perform tedious and rep...

Unmanned surface vessels took a step further toward becoming a reality when a U.S. Navy research and development programme attained its first objective – to build and demonstrate a vessel on the assumption that no person steps aboard at any point in its operating cycle.
The Textron Common Unmanned Surface Vessel (CUSV) vividly met this objective during the Navy’s 2011 ‘Sea Warrior’ experiment at Hampton Roads near the Norfolk Naval Base, clearing the way for subsequent Federal Government invitations to tender for work on the remaining objectives set out by the Defense Advanced Research Agency (DARPA) in its Anti-submarine Warfare Unmanned Vessel Continuos Trail (ACTUV) programme. A project aimed to develop an unmanned X-ship optimised to robustly track quiet diesel electric submarines.

In an attempt to improve the range of Unmanned Undersea Vehicles (UUVs), the alternative
energy company AlumiFuel Power Inc, (API) researching on behalf of the US Navy, into
possible use of hydrogen generation using steam and aluminum. This method produces the gas
using aluminum and steam (water) in a controlled exothermic reaction to producing hydrogen
gas, water and aluminum oxide. The rate of hydrogen emitted is simply controlled by the supply
of steam reacting with the aluminum which can be fed straight to a fuel cell or combustion
America's oldest commissioned warship, USS Constitution, and indeed the oldest such combatant in any navy, still gets underway, as it did yesterday to salute the U.S. Navy's victory at Midway Island during World War II with 200 Gold Star families aboard as guests. Although the ship does not operate without tug assistance, it does get underway, and on occasion will unfurl sails. Her Sailors must learn their sailing skills aboard the U.S. Coast Guard's training bark USCGC Eagle, home ported about two hours away at New London, Ct.Seeing the ship underway serves to remind us of a day when canvas and wind were the means of propulsion for virtually all ships, in trade or armed for war.Constitution’s crew today is very much a team of contemporary surface warriors in a high-tech Navy, but has the honor of perpetuating naval customs and traditions, not to mention technology. This is evident not only from her sails, but from her gig crew's participation in a recent boat r... [More]

Vericor Delivers For The US Navy
Alpharetta, GA - Vericor Power Systems LLC has been awarded a firm fixed-price contract for the manufacture, testing and delivery of up to 34 ETF40B marine gas turbine engines and overhaul of related hardware for the US Navy‘s FY2010/2011 Landing Craft Air Cushion (LCAC) Service Life Extension Program (SLEP).
The LCAC is an amphibious vehicle that operates in an environment that is unique in the naval fleet. The engines are exposed to sand and salt spray beyond any surface ship or aircraft operating environment. This environment requires a true marine design to deliver reliable power. “It’s hard to imagine an off-the-shelf aircraft engine lasting very long in this environment without substantial changes” states Rick Clinton, Vice President of Operations for Vericor. “The ETF40B along with its predecessor, the TF40B, have been operating on this craft, in this environment, for over 25 years. To... [More]
