155mm HE Rocket Assist Project Extended Range
Abstract
The 155 millimeter (mm) High Explosive (HE) Rocket Assisted Projectile, Extended Range Project supports projectile development efforts to achieve ranges of 40km in current 39 caliber artillery weapon systems and longer ranges in future 58 caliber Extended Range Cannon Artillery (ERCA) Self-Propelled Howitzer (SPH) to achieve the Army's requirement of extended range lethality. The Project is executing an evolutionary approach consisting of two parallel efforts to meet the objectives of extended range and precision. The XM1113 will replace the obsolete M549A1 in 39 caliber weapon systems and increase range from 30km to 40km. The XM1210 (formerly known as XM1113ER) will be optimized for 58 caliber guns and allow commanders to provide accurate cannon artillery fires at ranges of 70km and greater with ERCA. These efforts will leverage enhanced lethality cannon munition technologies to compensate for increased rocket motor volume. Fiscal Year (FY) 2023 funding will support the completion of XM1113 qualification activities, engineering efforts to evaluate test data to ensure that the projectile is safe, suitable and operationally effective as well as the gathering of all statutory and regulatory requirements in support of a Milestone C and Full Materiel Release (FMR). FY 2023 funding will also support XM1210 qualification and firing tables testing required for Safety Release for First Unit Issued (FUI) to support the ERCA Operational Assessment, Urgent Materiel Release (UMR) qualification activities and the initiation of FMR development activities.
