Observations in early testing of prototypes are showing excessive wear on the gun tube after firing a relatively low number of rounds.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cNew ammunition is as much of the challenge with the program as it is the weapon system,\u201d Doug Bush, the Army\u2019s acquisition chief, told Defense News in an interview ahead of the Association of the U.S. Army\u2019s annual conference.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cSo we\u2019ll know a lot more when we actually get through our testing and then get into the operational evaluations in terms of how long [of a] time between maintenance [is] required \u2014 reliability, basically,\u201d he added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Improving the rate of fire before the gun tube requires replacement could be achieved by adjustments in materials used and the design of the gun tube, adjustments to propellants, and the design of artillery rounds fired from the cannon, according to Col. Rory Crooks, the head of the Army\u2019s Long Range Precision Fires Cross-Functional Team<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Army is currently building 20 prototypes of the ERCA system: two for destructive testing and <a href=\"https:\/\/www.defensenews.com\/digital-show-dailies\/global-force-symposium\/2021\/03\/18\/us-army-nears-choosing-first-battalion-for-extended-range-cannon\/\" target=\"_blank\">the remaining 18 for a battalion<\/a> set to receive the weapons by the fourth quarter of fiscal 2023. That unit will then run the cannons through a yearlong operational test.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"1009\" src=\"\/wp-content\/uploads\/2026\/08\/4980451.jpg.jpg\" alt=\"\" class=\"wp-image-86928\" srcset=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4980451.jpg.jpg 1200w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4980451.jpg.jpg?resize=300,252 300w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4980451.jpg.jpg?resize=768,646 768w, https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/4980451.jpg.jpg?resize=1024,861 1024w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><figcaption class=\"wp-element-caption\">The Extended Range Cannon Artillery system is meant to be an improvement to the latest version of the Paladin self-propelled howitzer. (Edward Lopez\/U.S. Army)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The Army is on track to deliver those systems, Crooks told Defense News in a recent interview. That means the service will have built 20 prototypes in less than three years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Army has been putting together the ERCA systems across several different locations, including New York\u2019s Watervliet Arsenal, which makes the gun tubes. Their final integration will occur at Picatinny Arsenal in New Jersey, after which they\u2019ll head to Yuma Proving Grounds in Arizona for characterization testing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Army is continuously working to improve the quality of the gun tube during manufacturing at Watervliet so they can \u201chold up under conditions we want. That is not something you do on Day One; that is an ongoing process,\u201d Bush said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Seeing how the gun tube interacts with the new propellants and new rounds, as well as how they perform under operational conditions, will prove informative, he added. \u201cI think, for now, we believe there are technology adjustments and technique adjustments we can make to address [the issues], but it\u2019s too early to say for sure. So it\u2019s definitely a watch item.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe physics that are associated with the 58-caliber [gun tube] are different than the physics that are associated with a 39-caliber,\u201d Crooks said, \u201cand so the more iterations we get out of the tests on this 58-caliber tube at the supercharge ranges that we\u2019re employing, the more we address each of the things that come up.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cBut we\u2019ve certainly made accommodations with a different breech, and it was regarding tube wear. This is something that, as we get more information, as we apply different approaches thanks to [science and technology] work, we\u2019re going to continue to get after it.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One possible solution could be using ramjet artillery currently in development. The Army is exploring a 155mm ramjet capability, but in order for the service to invest more time, Crooks noted, the technology must \u201cmeet certain criteria, which is the cost. Costs have to be something that should not be on par with what rockets cost,\u201d Crooks said. \u201cAnd they need to be lethal.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Leading up to the operational test, <a href=\"https:\/\/www.defensenews.com\/land\/2022\/05\/23\/us-army-terminates-strategic-long-range-cannon-science-and-technology-effort\/\" target=\"_blank\">the Army will continue science and technology work<\/a> to help solve physics issues while continuing to \u201ctest, fix, test\u201d as it receives more prototypes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to Bush, the Army will hold a competition for the ERCA system \u201cat the appropriate time.\u201d The Army isn\u2019t planning to hold a competition for a company to build an entire vehicle from scratch.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWhat\u2019s being competed is taking a [Paladin Integrated Management] chassis, a modified cab and putting the new gun into it,\u201d Bush said.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The U.S. Army is counting on a major operational test of its Extended Range Cannon Artillery system to help it answer several
