The U.S. Army has already expressed an interest in just such a projectile, which could also end up in service with the U.S. Marine Corps, and the round might finally offer a way for the U.S. Navy to make use of\u00a0the cannons\u00a0on its new, stealthy\u00a0<em>Zumwalt<\/em>-class destroyers.<\/p>\n<p>The defense contractor revealed\u00a0a full-size mockup\u00a0of the design, which it is simply calling the 155mm Solid Fuel Ramjet at present, at the biennial Eurosatory arms expo in the French capital Paris, which began on June 11, 2018. The firm expects to begin live-fire testing of the projectile in 2019 or 2020 and hopes to have the new ammunition in production and in operational service with a military by between 2023 and 2024.<\/p>\n<div class=\"has-ad-column\">\n<div class=\"articleFragment paragraph\">\n<p>\u201cThis could be a game-changer for artillery,\u201d Thomas Danbolt, Vice President of Nammo\u2019s Large Caliber Ammunitions division, said\u00a0in a press releaseheadlined &#8220;We are basically launching a missile from a cannon!&#8221; on June 12, 2018. \u201cWith the exception of a small number of precision guided shells with 50-60 km range [approximately 30 to 40 miles], most artillery systems still fire across the same distances as they did when the M109 was introduced more than 50 years ago.\u201d<\/p>\n<div class=\"ad viewed\" data-ad-type=\"teAd\"><\/div>\n<p>The U.S. Army\u2019s\u00a0self-propelled M109\u00a0or\u00a0towed M777 155mm howitzers\u00a0have maximum ranges of around 12 miles using standard high-explosive shells. Using rocket-assisted ammunition, they can hit targets closer to 20 miles away. Nammo is separately working on an improved, rocket-boosted shell for the service,\u00a0the XM1113, which will have a maximum range of approximately 25 miles.<\/p>\n<\/div>\n<\/div>\n<div class=\"video-youtube\"><iframe loading=\"lazy\" id=\"e8ec9ac6-c4ab-421e-8a2f-3e4bfde7651f\" class=\"video-youtube__video\" src=\"https:\/\/www.youtube.com\/embed\/6J0XwLYmAc0?rel=0&amp;enablejsapi=1\" width=\"716\" height=\"358\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/div>\n<div class=\"has-ad-column\">\n<div class=\"articleFragment paragraph\">\n<p>By\u00a0extending the length\u00a0of the howitzer\u2019s barrel, the Army is hoping to nearly double those ranges. That still won\u2019t be anywhere close to the more than 60-mile maximum range that Nammo says it will be able to get out of its ramjet-powered projectile.<\/p>\n<p>According to the Norwegian company, the firing cycle would remain essentially the same for artillery crews, who would fire the projectile like any other shell. But normal shells essentially begin decelerating the moment they leave the cannon.<\/p>\n<p>The ramjet round uses the force of launch to get it moving fast enough to start the ramjet motor. A solid fuel source will get the projectile up to a maximum speed of three times the speed of sound and keep it moving at that speed\u00a0for approximately 50 seconds.<\/p>\n<p>This type of motor also reduces drag on the shell itself, since it&#8217;s actively pulling the projectile through the air. The firm, which has long built rocket motors for other companies\u2019 missiles, says it is looking into developing\u00a0its own ramjet missile\u00a0using the same technology, as well.<\/p>\n<p>We don&#8217;t know how much volume within the shell has to go toward the ramjet and fuel now rather than explosive or other payloads, which could reduce the punch of the round. However, the solid propellant offers an efficient fuel source and will help keep as much space as possible free within the body.<\/p>\n<\/div>\n<figure id=\"fig1\" class=\"figure \" tabindex=\"1\" data-pos=\"0\">\n<div class=\"figure-wrapper\"><img class=\"figure-image\" src=\"https:\/\/the-drive-3.imgix.net\/https%3A%2F%2Fs3.amazonaws.com%2Fthe-drive-staging%2Fmessage-editor%252F1528994156712-m109.jpg?auto=compress%2Cformat&amp;ixlib=js-1.2.1&amp;s=2153776fb03201417bcc2e0032bd2e9b\" alt=\"\" \/><\/p>\n<div class=\"credit\">US ARMY<\/div>\n<div class=\"caption-container\">\n<p>A US Army M109 self-propelled howitzer fires a conventional shell.<\/p>\n<\/div>\n<\/div>\n<\/figure>\n<div class=\"articleFragment paragraph\">\n<p>Pop-out fins and an unspecified guidance system will steer the projectile to its designated target. A GPS-assisted inertial navigation system (INS) arrangement will almost certainly guide the shell, at least at first.<\/p>\n<p>A laser- or millimeter wave radar-guidance package could add additional flexibility to the system in the future. These systems could allow the projectile to hit moving targets at long ranges and, in the case of a laser-guided round, with manned or unmanned aircraft or forward-deployed troops on the ground designating the target with a laser or otherwise sharing that information with the artillery unit.<\/p>\n<p>At Eurosatory 2018, Nammo\u2019s Danbolt noted that that the ramjet round wouldn\u2019t just extend the maximum range of a single howitzer, but would greatly expand the flexibility of individual artillery units to engage different targets. According to the executive, a six-gun battery would be able to hit anything within an approximately 1,500 square mile circle around their firing position with the new XM1113. The ramjet rounds would exponentially increase that possible target area to more than 12,000 square miles without the howitzers ever having to relocate.<\/p>\n<\/div>\n<div class=\"js-social-media-embed social-embed\" data-embed-type=\"twitter\" data-embed-id=\"1006472336692989952\">\n<div class=\"SandboxRoot env-bp-350\" data-twitter-event-id=\"0\">\n<div id=\"twitter-widget-0\" class=\"EmbeddedTweet EmbeddedTweet--cta js-clickToOpenTarget tweet-InformationCircle-widgetParent\" lang=\"en\" data-click-to-open-target=\"https:\/\/twitter.com\/RemigiuszWilk\/status\/1006472336692989952\" data-iframe-title=\"Twitter Tweet\" data-scribe=\"page:tweet\" data-twitter-event-id=\"1\">\n<div class=\"u-hiddenVisually js-aBScribingTarget\" data-experiment-keys=\"tfw_media_placement_9096\">\u00a0<img loading=\"lazy\" class=\"CroppedImage-image js-cspForcedStyle\" title=\"View image on Twitter\" src=\"https:\/\/pbs.twimg.com\/media\/Dfe1Nv0XkAAIzMJ?format=jpg&amp;name=360x360\" alt=\"View image on Twitter\" width=\"1200\" height=\"900\" data-image=\"https:\/\/pbs.twimg.com\/media\/Dfe1Nv0XkAAIzMJ\" data-style=\"left:-16%;\" \/><img loading=\"lazy\" class=\"CroppedImage-image js-cspForcedStyle\" title=\"View image on Twitter\" src=\"https:\/\/pbs.twimg.com\/media\/Dfe1OreWAAAmZOH?format=jpg&amp;name=360x360\" alt=\"View image on Twitter\" width=\"1200\" height=\"900\" data-image=\"https:\/\/pbs.twimg.com\/media\/Dfe1OreWAAAmZOH\" data-style=\" top:-24%;\" \/><img loading=\"lazy\" class=\"CroppedImage-image js-cspForcedStyle\" title=\"View image on Twitter\" src=\"https:\/\/pbs.twimg.com\/media\/Dfe1PlZW0AAEP3s?format=jpg&amp;name=360x360\" alt=\"View image on Twitter\" width=\"1200\" height=\"900\" data-image=\"https:\/\/pbs.twimg.com\/media\/Dfe1PlZW0AAEP3s\" data-style=\" top:-48%;\" \/><\/div>\n<div class=\"EmbeddedTweet-tweetContainer\">\n<div class=\"CallToAction-icon\" data-scribe=\"element:profile_icon\"><\/div>\n<div class=\"CallToAction-text\" data-scribe=\"element:profile_text\">See Remigiusz Wilk&#8217;s other Tweets<\/div>\n<div class=\"CallToAction-chevron\" data-scribe=\"element:cta_chevron\"><\/div>\n<\/div>\n<\/div>\n<div class=\"resize-sensor\"><\/div>\n<\/div>\n<\/div>\n<div class=\"articleFragment paragraph\">\n<p>What this means is that ground forces could operate far further from those elements while still having vital artillery support on call. Fewer artillery units could also cover a much wider front.

At the Association of the United States Army&#8217;s Global Force Symposium in March 2018, U.S. Army Brigadier General Stephen Maranian\u00a0specifically mentioned ramjet rounds\u00a0among other potential future artillery concepts.<\/p>\n<\/div>\n<figure id=\"fig2\" class=\"figure \" tabindex=\"1\" data-pos=\"1\">\n<div class=\"figure-wrapper\"><img class=\"figure-image\" src=\"https:\/\/the-drive.imgix.net\/https%3A%2F%2Fs3.amazonaws.com%2Fthe-drive-staging%2Fmessage-editor%252F1528994283351-football.jpg?auto=compress%2Cformat&amp;ixlib=js-1.2.1&amp;s=93b9dbad4ca1967fd64aad5e68a0d4d0\" alt=\"\" \/><\/p>\n<div class=\"credit\">US ARMY<\/div>\n<div class=\"caption-container\">\n<p>A slide from US Army Brigadier General Stephen Maranian&#8217;s briefing at Association of the United States Army&#8217;s Global Force Symposium that mentions ramjet artillery rounds as one means to extend the range of existing howitzers.<\/p>\n<\/div>\n<\/div>\n<\/figure>\n<div class=\"articleFragment paragraph\">\n<p>Maranian is in charge of the service\u2019s new \u201ccross functional team,\u201d or CFT, for Long Range Precision Fires, or LRPF, which is in charge of exploring advanced existing and future technologies to improve the range and capability of artillery units. The brigadier general\u2019s team\u00a0is also looking into\u00a0railguns, long-range \u201csuperguns,\u201d and\u00a0various ground-launched missiles.<\/p>\n<p>The U.S. Marine Corps, which will also eventually receive the XM1113 rocket-assisted 155mm shells, is likely to be interested in the ramjet round, which could be especially useful during\u00a0expeditionary and distributed operations. The significantly increased range would give Marines more options for where to deploy their own M777 howitzers to support friendly forces, especially in the Pacific Region, where relatively small outcroppings of land are often separated by large expanses of water.<\/p>\n<\/div>\n<figure id=\"fig3\" class=\"figure \" tabindex=\"1\" data-pos=\"2\">\n<div class=\"figure-wrapper\"><img class=\"figure-image\" src=\"https:\/\/the-drive-3.imgix.net\/https%3A%2F%2Fs3.amazonaws.com%2Fthe-drive-staging%2Fmessage-editor%252F1528994913088-m777.jpg?auto=compress%2Cformat&amp;ixlib=js-1.2.1&amp;s=3280d23e110d02d7c165f366905ae023\" alt=\"\" \/><\/p>\n<div class=\"credit\">USMC<\/div>\n<div class=\"caption-container\">\n<p>US Marines fire an M777 howitzer.<\/p>\n<\/div>\n<\/div>\n<\/figure>\n<div class=\"articleFragment paragraph\">\n<p>It might even make it a viable option to fire the guns from the decks of\u00a0amphibious ships\u00a0and\u00a0sea bases, turning those vessels into floating firebases. The Marines have already\u00a0begun exploring this concept\u00a0with their truck-mounted High Mobility Rocket Artillery Systems (HIMARS).<\/p>\n<p>And in the same vein, Nammo\u2019s ramjet round could be an ideal option for the U.S. Navy to add the presently ammo-less 155mm guns on its\u00a0<em>Zumwalt<\/em>-class destroyers. Since the goal seems to be for the new projectile to work with any existing system, it would be a far simpler option than replacing the cannons on the ships with another, entirely different system.<\/p>\n<p>In 2016, the Navy decided not to buy the 155mm Long-Range Land Attack Projectile (LRLAP) round, given its exorbitant cost of $800,000 per shell. This has since left the\u00a0<em>Zumwalt<\/em>\u2019s guns as effectively dead weight, since existing howitzer ammunition does not have the necessary range to be a useful substitute.<\/p>\n<\/div>\n<\/div>\n<div class=\"video-youtube\"><iframe loading=\"lazy\" id=\"b14764c1-cb36-423e-815a-954c7f7c00b5\" class=\"video-youtube__video\" src=\"https:\/\/www.youtube.com\/embed\/cH11dBX9P3g?rel=0&amp;enablejsapi=1\" width=\"806\" height=\"403\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/div>\n<div class=\"has-ad-column\">\n<div class=\"articleFragment paragraph\">\n<p>The main question then becomes, just how expensive will Nammo\u2019s ramjet round actually be? If its cost grows to anywhere near that of the LRLAP, it could easily turn off any prospective buyers.<\/p>\n<p>Still, if any branch of the U.S. military does decide to take the lead on the ramjet project, they could easily look to allies and partners to help share the cost burdens. South Korea, in particular, could be very interested in the new ammunition, which would allow its howitzers to reach\u00a0further into North Korea\u00a0during a conflict or let units move further away from the demilitarized zone where fighting would be especially heavy in the event of an actual war.<\/p>\n<p>In 2016, South Korean defense contractor Poongsan revealed its own ramjet artillery shell concept, which had an estimated range of nearly 50 miles.\u00a0According to Jane&#8217;s 360, this design would be slower and would have less fuel for its motor than Nammo&#8217;s round.<\/p>\n<\/div>\n<figure id=\"fig4\" class=\"figure \" tabindex=\"1\" data-pos=\"3\">\n<div class=\"figure-wrapper\"><img class=\"figure-image\" src=\"https:\/\/the-drive.imgix.net\/https%3A%2F%2Fs3.amazonaws.com%2Fthe-drive-staging%2Fmessage-editor%252F1528995054518-ap_910282001721.jpg?auto=compress%2Cformat&amp;ixlib=js-1.2.1&amp;s=69b3739a841ace1fac6b3053bf10ee92\" alt=\"\" \/><\/p>\n<div class=\"credit\">AP PHOTO\/YONHAP, LIM BYUNG-SHICK<\/div>\n<div class=\"caption-container\">\n<p>A South Korean M109 self-propelled howitzer fires a shell during an exercise.<\/p>\n<\/div>\n<\/div>\n<\/figure>\n<div class=\"articleFragment paragraph\">\n<p>NATO members in Europe, especially those along the alliance\u2019s eastern flank\u00a0right up against Russia, might be interested in the ramjet-powered projectiles for similar reasons. In\u00a0the Baltic Sea region, the shells could allow\u00a0the small Baltic States\u00a0of Estonia, Latvia, and Lithuania, or other allies in those countries or nearby, to better cover all avenues of approach at once even with limited artillery units.<\/p>\n<p>Nammo\u2019s Danbolt declared that the ramjet projectile could \u201ccompletely change\u201d how traditional artillery units operate. With the significant added range, those elements would be able to potentially operate with smaller footprints, better shielded from threats in both low- and high-end conflicts, while covering the same total area.<\/p>\n<\/div>\n<figure id=\"fig5\" class=\"figure \" tabindex=\"1\" data-pos=\"4\">\n<div class=\"figure-wrapper\"><img class=\"figure-image\" src=\"https:\/\/the-drive-2.imgix.net\/https%3A%2F%2Fs3.amazonaws.com%2Fthe-drive-staging%2Fmessage-editor%252F1528995653080-pz2000.jpg?auto=compress%2Cformat&amp;ixlib=js-1.2.1&amp;s=e85d16194245a1ad89c278173274a278\" alt=\"\" \/><\/p>\n<div class=\"credit\">US ARMY<\/div>\n<div class=\"caption-container\">\n<p>German artillery troops fire a PzH 2000 self-propelled howitzer during a NATO exercise.<\/p>\n<\/div>\n<\/div>\n<\/figure>\n<div class=\"articleFragment paragraph last-paragraph\">\n<p>But it\u2019s also not the only concept that companies are pitching to squeeze more range out of existing 155mm howitzers. The Army, in cooperation with the Navy, is separately exploring the possibility of launching inert,\u00a0hypervelocity projectiles\u00a0derived from\u00a0experimental railgun ammunition\u00a0from standard cannons. These would reach the same speed as the ramjet round, but would still likely have a significantly shorter overall range.<\/p>\n<p>There may also a cost question when it comes to wear and tear on the gun barrels. The more rounds you fire at higher speeds through a howitzer, the faster the rifling and overall structural integrity of the system\u00a0wears down. This reduces overall accuracy and can potentially lead to catastrophic failures.<\/p>\n<p>Depending on how fast crews need to fire the ramjet shells to get them to the appropriate speed, and whether or not the round&#8217;s motor begins to work inside the barrel, the ammunition could exert a high strain on the howitzer\u2019s barrel and shorten the time before units need to replace them. Improvements to the existing guns could help mitigate these issues and extend barrel life, but would again require additional time and resources.<\/p>\n<p>Whatever happens, there\u2019s no denying that the ramjet artillery shell, if it works, will be an impressive feat of engineering and could offer game-changing capabilities for traditional howitzers.<\/p>\n<\/div>\n<\/div>\n<p>Fuente:\u00a0<em><a href=\"https:\/\/www.thedrive.com\/the-war-zone\/21531\/yes-this-is-a-ramjet-powered-artillery-shell-and-it-could-be-a-game-changer\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/www.thedrive.com<\/a><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>La Compa\u00f1\u00eda Noruega NAMMO, avanza en el desarrollo de un proyectil de artiller\u00eda verdaderamente revolucionario que podr\u00eda convertirse en un \u201cGame Changer\u201d para la artiller\u00eda&hellip; <\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[18,29,24],"tags":[],"_links":{"self":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/posts\/4075"}],"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=4075"}],"version-history":[{"count":0,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/posts\/4075\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=4075"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=4075"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=4075"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
