The need to keep the system\u2019s components cool creates additional power requirements.<\/p>\n<p class=\"article-paragraph skip\">Sustained firing of projectiles at very high speeds also increases the rate of wear on the barrel.

The railgun now on JS\u00a0<em>Asuka<\/em>\u00a0is notably fixed to the ship\u2019s rear flight deck where there is ample open space.

Japan has previously expressed interest in this capability explicitly to help protect against incoming hypersonic threats. Such a weapon would also offer benefits in terms of magazine depth and cost compared to traditional surface-to-air and surface-to-surface missiles, given the small size and lower unit price of the individual rounds.<\/p>\n<p class=\"article-paragraph skip\">When it comes to warships, in particular, where physical space is at a premium and where options for reloading missiles at sea can be at best extremely limited, having a weapon system firing lower-cost munitions from a large magazine and that can engage a broad swath of target sets would be a clear boon.<\/p>\n<p class=\"article-paragraph skip\">Japan is not the only country to be pursuing railguns, or to have done so in the past, especially for maritime use, for exactly these reasons. Between 2005 and 2022, the U.S. Navy was\u00a0<a href=\"https:\/\/www.twz.com\/28669\/navys-railgun-now-undergoing-tests-in-new-mexico-could-deploy-on-ship-in-northwest\" target=\"_blank\" rel=\"noreferrer noopener\">actively working on a railgun<\/a>\u00a0to arm future ships before, as previously noted,\u00a0<a href=\"https:\/\/www.twz.com\/40875\/the-navys-railgun-looks-like-its-finally-facing-the-axe-in-new-budget-request\" target=\"_blank\" rel=\"noreferrer noopener\">shelving the effort<\/a>\u00a0in the face of technical issues.
