Photos posted by a Chinese People’s Liberation Army Navy (PLAN) observer show what appears to be an electromagnetic railgun being affixed to a PLAN tank landing ship, the Haiyang Shan . The LST is being used to test the weapon because its tank deck can accommodate the containers for the gun’s control system and power supply, according to comments from a former PLAN officer translated by ” Dafeng Cao ,” the Twitter handle of the anonymous analyst. For nearly a decade, the US Navy’s Office of Naval Research (ONR) and various contractors worked to develop a railgun system for US ships . A prototype weapon was built by BAE Systems. Testing at the US Navy’s Naval Surface Warfare Center in Dahlgren, Virginia was deemed so successful that the Navy was planning to conduct more testing of the gun at sea aboard a Spearhead -class Joint High Speed Vessel (JHSV). The program promised to deliver a gun that could fire projectiles at speeds over Mach 7 with a range exceeding 100 miles. The 23-pound hypervelocity projectile designed for the railgun flying at Mach 7 has 32 megajoules of energy—roughly equivalent to the energy required to accelerate an object weighing 1,000 kilograms (1.1 US tons) to 252 meters per second (566 miles an hour).

US dropped ball on Navy railgun development—now China is picking it up
It’s been successfully tested on trucks, as well as UAVs and small rockets, according to a video from Lockheed Martin, which is now shipping the first 60kW-class “beam combined” fiber laser for use by the U.S. Army. An anonymous reader quotes the Puget Sound Business Journal: Lockheed successfully developed and tested the 58 kW laser beam earlier this year, setting a world record for this type of laser. The company is now preparing to ship the laser system to the U.S. Army Space and Missile Defense Command/Army Forces Strategic Command in Huntsville, Alabama [according to Robert Afzal, senior fellow for Lockheed’s Laser and Sensor Systems in Bothell]. “We have shown that a powerful directed energy laser is now sufficiently light-weight, low volume and reliable enough to be deployed on tactical vehicles for defensive applications on land, at sea and in the air…” Laser weapons, which complement traditional kinetic weapons in the battlefield, will one day protect against threats such as “swarms of drones” or a flurry of rockets and mortars, Lockheed said.

cold fjord writes: It will soon be a bit more difficult for Britain’s Royal Navy to rule the waves as it gives up anti-ship missiles as a result of budget cuts. That will force the Royal Navy to go “old school” and rely upon naval gunfire for ship-to-ship combat. Cannon fire as the primary means of ship-to-ship combat has been largely obsolete since the 1950s following the invention of guided missiles in World War 2. Prior to that, cannon fire had been the primary means of naval combat for hundreds of years. Although the Royal Navy ranged up to 16″ guns on battleships, the largest gun currently in active service is a 4.5″ gun. That will leave the Royal Navy unable to engage targets beyond approximately 17 miles / 27 km, whereas Harpoon missiles provide an 80 mile / 130 m range. The loss of anti-ship missile capability will begin in 2018 and may last for 10 years for warships, and 2 years for helicopters. The Sun quotes a naval insider who said: “It’s like Nelson saying, ‘don’t worry, I don’t need canons, we’ve got muskets.'” The loss of missile capability heaps more misfortune upon a naval force that recently has seen its available frontline combat force drop to an unprecedented 24 warships.
