Railguns need only CIWS to defend it against income missiles that escape long and medium range interception, the gun itself can destroy any missiles at the blink of an eye since it is expected to shoot a projectile up to speed of mach 10, and upto a range of 200nm or 370 km. However all these will be at the future as currently they are still at experimental stage.

On January 31, 2008 the US Navy tested a railgun that fired a shell at 10.64 MJ with a muzzle velocity of 2,520 m/s (8,270 ft/s).[27] Its expected performance is a muzzle velocity over 5,800 m/s (19,000 ft/s), accurate enough to hit a 5-metre (16 ft) target over 200 nmi (370 km) away while firing at 10 shots per minute. The power was provided by a new 9-megajoule prototype capacitor bank using solid-state switches and high-energy-density capacitors delivered in 2007 and an older 32-MJ pulse power system from the US Army’s Green Farm Electric Gun Research and Development Facility developed in the late 1980s that was previously refurbished by General Atomics Electromagnetic Systems (EMS) Division.[28] It is expected to be ready between 2020 to 2025.[29]
A test of a railgun took place on December 10, 2010, by the US Navy at the Naval Surface Warfare Center Dahlgren Division.[30] During the test, the Office of Naval Research set a world record by conducting a 33 MJ shot from the railgun, which was built by BAE Systems.[31][32]
A more recent test took place in February 2012 at the Naval Surface Warfare Center Dahlgren Division. While similar in energy to the aforementioned test, the railgun used is considerably more compact, with a more conventional looking barrel.[33] A General Atomics-built prototype was delivered for testing in October 2012.[
