AN ELECTROMAGNETIC ARMS RACE HAS BEGUN: CHINA IS MAKING RAILGUNS TOO
By Jeffrey Lin and P.W. Singer

Chinese Railgun This early Chinese railgun or coilgun (pre-2005) is part of Chinese electromagnetic research, which began in the 1980s. While railguns are relatively simple to build, the difficulty lies in scaling them up, as well as making the barrel durable enough for multiple firings. Chinese Internet, via Strategy Center
A Chinese defense contractor may be on its way to key breakthroughs in railgun weaponry.

Railguns are one of the potential game-changing weapons of future war. Instead of using the power of chemical explosives such as gunpowder, a railgun uses electromagnetic force to propel projectiles to hypersonic speeds, potentially up to ranges of several hundred miles. A railgun's barrel has two parallel conducting rails built into it. When a moving armature (usually the projectile) is inserted into the barrel, it connects the parallel rails to complete the current, thus generating an intense electromagnetic field. The projectile then accelerates out of the barrel at high speeds.
206 Institute Scientists at CASIC's 206th Institute in the lab. Scientists at the 206th Institute among China's leading researchers in applied electromagnetic launch (including technologies like railguns and EMALS catapults).
These new class of weapons are considered by the US Navy to be a key technology for meeting 21st century warfighting needs, most notably in plans for countering China's military growth. Until now, the tech have been primarily a US dominated space; the U.S. Navy for example will test a railgun on the USNS Trenton starting in 2016. This seems to be changing.
7th Chinese Electromagnetic Technology Conference At the 7th Chinese Electromagnetic Technology Conference in Oct 2015, Chinese scientists presented advances in key railgun technologies, such as toughened barrels to allow for rapid railgun firing in combat conditions. CASIC
The China Aerospace Science and Industry Corporation (CASIC) has reported online that its 206 Institute, which researches electromagnetic launch technologies, has made breakthroughs in electromagnetically launch boosted missiles and railguns designed for close in weapons systems (CIWS). This follows the 206 Institute's hosting of the Seventh Chinese Electromagnetic Technology Conference in Oct 2015, which also reported advances in material sciences to reduce railgun barrel wear (while railgun technology have been tested since 1918, power generation and the wearing out of the barrel are longstanding barriers to the deployment of militarily useful railguns).
Wuhan EMALS This satellite photo shows a test facility at the Chinese naval research facility in Wuhan. Speculation is that it is the prototype for the Chinese EMALS catapult system, which would be equipped on future Chinese carriers (Type 002?). hmmwv at China Defense Forum
Phoenix Television reported on a number of other related railgun research advances. An early November 2015 news broadcast stated that Chinese researchers have made breakthroughs in electromagnetic aircraft launch systems (EMALS) and railguns, in areas from power storage to tougher barrel materials. EMALS catapults could be installed on Chinese aircraft carriers in the next decade, improving the performance of Chinese naval aircraft. The Phoenix TV broadcast also suggested that the PLAN hopes to test its own operational railgun in the next couple of years.
Type 1130 CIWS The Type 1130 CIWS, with 11 30mm barrels, is the largest Gatling cannon in the world, firing up to 11,000 rounds a minute (that's nearly 200 rounds a second). Its designers say that it can shoot down 90% of incoming supersonic missiles. But it could be replaced by shipborne railguns, which would protect Chinese warships against future hypersonic threats. =GT at China Defense Forum
Despite longstanding public conceptions of China only developing copycat weapons aided by intellectual property theft and espionage (such as the F-35 and J31 fighter jet similarity) , China's progress in developing new cutting edge military technologies like railguns actually reflects a deep investment in the field. Chinese scientists from civilian and military universities submitted the most papers at the Institute of Electrical and Electronic Engineers's 2014 Symposium on Electromagentic Launch in California, and China will host the upcoming 2016 Symposium as well.
Type 055 The second batch of Chinese Type 055 destroyers will likely feature railguns, starting in the 2020-2025 timeframe. A 32 megajoule railgun on the Type 055 destroyer would be able to launch a ten kilogram projectile over a 100 nautical miles away, with the impact energy of medium artillery. Railgun ammunition can be guided, and programmed to explode over a target, destroying soft targets like parked aircraft and missile launchers. lt.cdjby.net
The likely use of the reported railgun in a close in weapons systems (CIWS) would be to defend Chinese warships and bases against not just conventional airplanes and missiles, but also hypersonic and ballistic missiles. But China's recent progress in railgun technology also points to their potential in the same long range fight role the US navy envisions (covered in the recent book Ghost Fleet). There have been online rumors that suggest that the second batch of Type 055 guided missile destroyers (potentially to be termed the Type 055A, following the naming pattern) will be armed with large railguns in the place of older 130mm cannons, for long range anti-surface and air defense warfare. The putative Type 055A destroyer class would likely be launched after 2020, and feature integrated electrical propulsion, for increased power generation to power railguns, lasers and advanced sensors.
Blitzer Railgun The 10MJ General Atomic Blitzer railgun can be put on a mobile ground launcher, supported by two generator vehicles to power it. Future advances in power generation and storage could result in more powerful railguns, with ranges of hundreds of miles, replacing Chinese short ranged ballistic missiles. IHS JANES
Just as a railgun was recently shown off at the US Army Association's national convention, the technology might also be based on land, where indeed the power generation issues are less challenging than trying to fit onboard a ship. Large Chinese railguns could also be placed on ground vehicles (similar to the General Atomic Blitzer) to provide mobility, concealed on Chinese territory while defended by A2/AD systems. The long range and accurate rapid fire capabilities of railguns would give the PLA a cheaper, higher volume of fire, and less risky alternative to current ballistic, cruise missile and air strikes in the Chinese arsenal.
A railgun technology arms race seems to be happening, and it is something to keep a close watch. It could very well reshape what is possible or not in the Pacific security issues in the decades to come.
