It was a three-day campaign noted to have occurred in February 2025 as a joint effort between the WSD and the NSWC Dahlgren Division in Virginia for NAVSEA\u2019s Joint Hypersonics Transition Office.<\/p>\n
However, the objectives and findings of the testing were not disclosed.<\/p>\n
Its occurrence raises further questions, as the US Navy\u00a0canceled railgun research and development efforts<\/a>\u00a0in 2021, citing fiscal constraints, technical hurdles, and shifting priorities to hypersonic missile development.<\/p>\n There has been no public information that any sort of testing has taken place after the program was put on hold, up until February 2025.<\/p>\n Railgun Revival?<\/strong><\/p>\n Unlike traditional guns that rely on gunpowder, railguns use electromagnetic force to fire projectiles at extremely high speeds, potentially lowering the cost per shot while launching kinetic projectiles that are harder to intercept.<\/p>\n In October 2025, General Atomics Electromagnetic Systems (GA-EMS) advanced its railgun program by\u00a0unveiling electromagnetic weapons<\/a>\u00a0designed to fire projectiles at hypersonic speeds against ballistic and cruise missiles.<\/p>\n The company said it proposed the weapon for US President\u00a0Donald Trump<\/strong>\u2019s\u00a0\u201cGolden Dome\u201d initiative<\/a>, which aims to build a multi-layered missile defense system to protect the US homeland against ballistic, hypersonic, and cruise missile threats.<\/p>\n Moreover, as ships with sufficiently powerful electrical systems can realistically operate electromagnetic railguns, talks have been underway about the possibility of the weapon being mounted on \u201cTrump-class\u201d battleships.<\/p>\n Announced<\/a>\u00a0by Trump in December 2025, the proposed vessels are expected to be the \u201clargest\u201d guided-missile surface combatants since World War II, measuring 880 feet (268 meters) long and weighing 30,000 to 40,000 tons.<\/p>\n \u201cOur goal is to understand, really, what the requirements will be for Defiant and the Trump-class, so that we can get the right configuration to put forward for that new ship,\u201d GA-EMS VP of Defense Systems & Technologies\u00a0Nick Bucci\u00a0<\/strong>informed<\/a>\u00a0Naval News<\/em>\u00a0in December.<\/p>\n![\"\"](\"https:\/\/www.fie.undef.edu.ar\/ceptm\/wp-content\/uploads\/2026\/03\/US-Navy-railgun-testing-.jpg\")
