El Ej\u00e9rcito de EE. UU. complet\u00f3 una nueva prueba del sistema de artiller\u00eda de ca\u00f1\u00f3n de alcance extendido (ERCA), alcanzando un objetivo a m\u00e1s de 40 millas (65 km) de distancia. El ERCA (artiller\u00eda de ca\u00f1\u00f3n de alcance extendido) est\u00e1 en desarrollo como una plataforma que debe ser compatible con m\u00faltiples configuraciones de ob\u00fas, m\u00faltiples proyectiles y m\u00faltiples misiones.<\/p>\n
The ERCA program has been testing various components of its system for about four years. The newest component undergoing testing is a five-round limited capacity autoloader. It holds five projectiles and five propellant charges.<\/p>\n
In the past ERCA Howitzer Test Bed (HTB) systems have been built on modified M109A6<\/strong><\/a> Self Propelled Howitzers. Testing of the limited capacity autoloader is being conducted from a prototype M109A7<\/strong><\/a> which has been modified and integrated with the ERCA Armament System.<\/p>\n In July 2019, U.S. Army has awarded BAE Systems $45 Million contract for Extended Range Cannon Artillery prototype. This prototype phase will address capability gaps in the Army\u2019s indirect fire systems and improve the rate and range of fire with the development of power distribution software and hardware integration solutions. ERCA will be integrated onto the M109A7 and will require the M109A7\u2019s current 39-caliber turret to be replaced with a 58-caliber, 30-foot long gun barrel with the objective of creating firepower double the current range.<\/p>\n The development program aims to provide extended range while maintaining the weight found in current systems to minimize performance impacts on the chassis. Under separate contracts, BAE Systems is also developing precision guidance kits with anti-jamming capabilities (PGK-AJ) that can operate in the challenging ERCA firing environment. PGK-AJ is compatible with existing and new long-range rounds for multiple firing platforms, including the M109 self-propelled howitzer.<\/p>\n Development work on ERCA Self Propelled Howitzer takes place at the Army\u2019s Picatinny Arsenal and BAE Systems\u2019 facilities in York, Pennsylvania; Sterling Heights, Michigan and Minneapolis, Minnesota.<\/p>\n
