The US Marines have demonstrated a half-scale version of their proposed amphibious vehicle...

In a recent demonstration carried out during RIMPAC 2014, the US Marines displayed and tested a fully-functional, half-scale prototype of its new amphibious transport vehicle. In its proposed full-size version the Ultra Heavy-Lift Amphibious Connecter (UHAC) concept is designed to power across the water with a payload of nearly 200 tons (180 tonne) at up to 20 knots (23 mph/37 km/h) and be capable of driving up on to the shore and over the top of obstructions up to 10 ft (3 m) high.  Read More

A fighter plane taking off from a strike carrier is a dramatic sight – not the least because of the woosh and plume of steam as the catapult blasts the aircraft into the air. In a few years, such launches may still be dramatic, but they’ll also be a bit quieter and very plume-free. That’s because the US Navy has completed testing of its Electromagnetic Aircraft Launch System (EMALS); clearing it for use on the new Gerald R Ford-class aircraft carriers.  Read More

The US Navy is deploying its first laser weapon on the USS Ponce in a few months. The technology also has obvious potential for ground vehicles – a fact that hasn't escaped the US Marine Corps. The Office of Naval Research has awarded contracts to develop a similar laser weapon that can be installed in light-tactical vehicles instead of ships as part of its Ground-Based Air Defense Directed Energy On-the-Move (GBAD) program.  Read More

NeRD is a compromise technology designed to give sailors an e-reader that won’t give Blofe...

Bucking the "more is better" trend of digital technology, the US Navy has unveiled an e-reader that’s notable for its lack of features. Designed to provide service personnel with digital format books without breaching security, the Navy e-Reader Device (NeRD) lacks networking capabilities like Wi-Fi, or the ability to add or remove anything from its digital library.  Read More

The X-47B, shown here on its first night flight in April, is set to begin its next round o...

The US Navy is preparing to conduct a series of test activities with the aim of nailing down air standard operating procedures for air traffic control and ground support designed to allow the X-47B unmanned aircraft to operate alongside manned aircraft, both in the air and on the deck of a flight carrier.  Read More

The newly-developed nanocrystalline spinel could lead to enhanced protection for personnel...

A team of experts at the US Naval Research Laboratory (NRL) has developed a new way of fabricating spinel, an armor material used in the windows of military vehicles, demonstrating that the strength of transparent ceramics could be dramatically improved. The nanocrystalline spinel is 50 percent harder than the spinel currently used in armored vehicles and could result in enhanced protection for personnel.  Read More

Artist's concept of a ship equipped with a railgun turret (Image: US Navy)

Watching old war movies, we expect firing a navy gun to be accompanied by a deafening bang and a dramatic cloud of burnt powder. This being the 21st century, the US Navy has other ideas as it prepares to install and test a prototype electromagnetic railgun on a Spearhead-class joint high speed vessel in 2016 as part of a program to develop the naval artillery of the future.  Read More

The X-47B on its first night flight carried out at Naval Air Station Patuxent River on Apr...

After taking to the air for the first time in early 2011, the X-47B Unmanned Combat Air System has been ticking off a series of firsts, including being the first unmanned aircraft to launch and recovery from a modern aircraft carrier. Another box has now been ticked with the aircraft completing its first night flights.  Read More

The MQ-4C Triton test aircraft makes its approach for landing March 13 at Palmdale, Califo...

The Triton UAV's initial flight test program, which kicked off with the unmanned aircraft's first flight last May, has been completed. Now cleared to fly at various altitudes, speeds and weights, the Triton is on track to be introduced into the US Navy fleet in 2017.  Read More

Starboard profile of Alvin that is returning to service after a three-year overhaul

The National Science Foundation (NSF) announced on Friday that the Alvin deep-sea submersible is returning to service. The DC3 of the oceanographic world was launched fifty years ago in 1964 and is ready to begin its second half-century of service after a three-year overhaul involving significant redesigns and upgrades.  Read More
