El US Army lleva adelante diversos programas para el desarrollo de futuros proyectiles de artiller\u00eda de calibre 155mm, que sean capaces de hasta triplicar el alcance de los actualmente disponibles, disparados desde los sistemas de armas en servicio.\u00a0Las Compa\u00f1\u00edas Boeing (EUA) y Nammo (Noruega)\u00a0ensayaron exitosamente el proyectil de artiller\u00eda con propulsi\u00f3n \u201cRamjet 155mm<\/em>\u201d. Adem\u00e1s de la propulsi\u00f3n adicional, este proyectil dispone de guiado de precisi\u00f3n, as\u00ed como superficies de sustentaci\u00f3n y control, por lo que algunos expertos opinan que bien puede considerarse como un \u201chibrido\u201d entre un proyectil de artiller\u00eda guiado y un misil. En esta primera etapa se verific\u00f3 la estabilidad del proyectil y el funcionamiento de su sistema de propulsi\u00f3n. Con la estabilidad y la propulsi\u00f3n verificadas, la pr\u00f3xima etapa ser\u00e1n los ensayos del alcance y del guiado de precisi\u00f3n. Se estima que su alcance ser\u00eda de 70 km.<\/p>\n

SMD 2022 \u2014 Boeing and Norwegian defense company Nammo successfully tested their air-breathing artillery projectile during a recent test in the Nordic nation, the companies announced today, the latest development in the US Army\u2019s effort to develop longer range artillery for future conflicts.<\/p>\n

The Ramjet 155 projectile is part of the\u00a0Army\u2019s XM1155 program<\/a>, an effort under the service\u2019s Extended Range Artillery Munition Suite Technology effort that\u2019s exploring advanced technology to extend the reach and effectiveness of artillery rounds.<\/p>\n

\u201cWe believe the Boeing Ramjet 155, with continued technology maturation and testing, can help the U.S. Army meet its long-range precision fires modernization priorities,\u201d said Steve Nordlund, Boeing Phantom Works vice president and general manager, said in a statement. \u201cThis successful test is evidence that we are making great progress.\u201d<\/p>\n

According to Dan Palmeter, business development lead for Boeing Phantom Works, the June 28 test successfully verified that the ramjet projectile could stay stable in flight and that the ramjet engine was able to ignite to sufficiently propel it.<\/p>\n

\u201cThe biggest challenge we\u2019ve had with it is to get it stable, get it flying, get good thrust [and] get good motor burn,\u201d Palmeter told Breaking Defense in an interview at the Space and Missile Defense Symposium in Huntsville, Ala.<\/p>\n

Boeing describes the Ramjet 155 projectile as a \u201chybrid\u201d between guided artillery and a missile. The successful test of the ramjet projectile is an important step forward, Palmeter said, because now Nammo and Boeing can focus on other capabilities, such as range.<\/p>\n

\u201cOnce you have the propulsion and the stability figured out, then comes the range, the guidance and the rest of the system,\u201d Palmeter said.<\/p>\n

According to a Boeing fact sheet, the ramjet technology aims to extend the Army\u2019s 155m howitzer\u2019s range to more than 70 kilometers, up from 40 kilometers.<\/p>\n

According to Mark Altobelli, director of\u00a0Boeing Phantom Works, that the ramjet projectile survived the cannon launch was a victory in itself, as that has presented a challenge in the past. The companies said they have now completed over 450 tests of the artillery.<\/p>\n

\u201cIn terms of packaging, think of it almost like a philharmonic orchestra,\u201d Palmeter said. \u201cEverything has to be working in concert.\u201d<\/p>\n

With the flight stability and propulsion performance verified in the recent test, the team will now work toward guided flights, which Altobelli called the \u201cnext big milestone.\u201d Those flights will occur in 2023 and 2024, he said.<\/p>\n

The Army awarded Boeing and Nammo a contract in July 2019 to develop the Ramjet 155 projectile and was subsequently awarded a phase two technology development contract in May 2021, according to Boeing.<\/p>\n

\u201cWe have great confidence in the ramjet concept,\u201d Nammo Chief Executive Officer Morten Brandtz\u00e6g said in a statement. \u201cThe test \u2014 with all aspects from cannon firing, to the projectile body, fins, and trajectory all functioning perfectly \u2014 represents a real technological breakthrough in artillery, and a major success for Boeing, Nammo, and the U.S. Army.\u201d<\/p>\n
