told <\/u>Defense News<\/u><\/a> during a Dec. 30 interview.<\/p>\n\u201cPrimarily because it will slow the engineering work that I have to do to get that power transference that I need to get multiple repeatable shots that I can now install in a ship. And I would frankly rather have an operational unit faster than have to take the nine months to a year it will take to set up the demo and install the systems, take the one operational [railgun] unit I have, put it on a ship, take it to sea, do a dozen shots, turn around, take it off, reinstall it into a test bed.\u201d<\/p>\n
Fanta said that he believes that an operational railgun is feasible within the next five years. Indeed, the Navy hopes to replace one of the 155mm gun turrets onboard the third and final Zumwalt<\/em>-class destroyer Lyndon B. Johnson<\/em> (DDG 1002) with a rail gun. \u201cI don\u2019t know if I can get there from the engineering status yet. But that\u2019s what we continue to look at,\u201d Fanta told Defense News.<\/em><\/p>\nAccording to Fanta, most of the key technologies behind railguns\u2014which have until now mostly been in the realm of science fiction\u2014have been unlocked. \u201cIt\u2019s engineering at this point, it\u2019s no longer science,\u201d Fanta told Defense News<\/em>. \u201cIt\u2019s no longer the deep dark secrets of what can I do with this sort of energy. It\u2019s engineering and how much power density can I get, how much beam quality can I get, what sort of metallurgy do I need to sustain multiple shots over multiple periods of time. The rail gun as well as the laser.\u201d<\/p>\nSolving the metallurgy problem might require novel solutions\u2014and it\u2019s possible a solution might not exist. \u201cMy old gun barrels used to last me a few thousand rounds. Is that still the way we want to go? Other countries are solving it the other way,\u201d Fanta told Defense News<\/em>.<\/p>\n\u201cMaybe if I carry four barrels and have them easily swapped out with a bunch of bosun\u2019s mates on the [forecastle] and stick [them] in and a half-turn and you go. It\u2019s kind of the way we do it when we overheat machine guns. The new machine guns, you got the old barrel, you stick in a new one and you keep shooting. Maybe that\u2019s the way to go if we can\u2019t solve the metallurgy issues that allow me to do 1,000 rounds out of a barrel.\u201d<\/p><\/blockquote>\n
Eventually, the Navy will have to test a full-up railgun. The trick will be to find a suitable range where the weapon can be fired at maximum range and velocity. But if the test program moves from Dahlgren, Virginia, to the White Sands Missile Range in New Mexico, it won\u2019t be able to conduct the at-sea demo onboard a fast transport.<\/p>\n
\u201cI need to be able to see how this thing\u2014for both the projectile and the gun\u2014how it shoots at full range, which means I need both elevation and altitude and long range where I can go blow the top off a mountain someplace and not worry about someone fishing around somewhere,\u201d Fanta told Defense News. <\/em>\u201cThe discussion now [is to] move it to a better site that allows me to do full range testing, or do I go do the demo? Because it\u2019s an either\/or, it\u2019s not both at this point.\u201d<\/p>\nFuente:<\/strong> https:\/\/nationalinterest.org<\/a><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"El desarrollo de ca\u00f1ones electromagn\u00e9ticos del tipo \u201cRailgun\u201d es un objetivo de todas las grandes potencias y hasta hace algunos a\u00f1os, parec\u00eda inalcanzable por los… <\/p>\n","protected":false},"author":1,"featured_media":5032,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[18],"tags":[],"_links":{"self":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/posts\/5031"}],"collection":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=5031"}],"version-history":[{"count":0,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/posts\/5031\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/media\/5032"}],"wp:attachment":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=5031"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=5031"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=5031"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
