One aspect of Extended Range Cannon Artillery currently being tested at the proving ground is the XM1113 projectile. “This is one in a series of engineering tests we have been conducting to improve the reliability of the projectile,” said Anthony Austria, test officer. “We’re testing a large sample across a range of temperatures and firing zones.” Though capable of substantially longer ranges, the new projectile is remarkably similar to currently- fielded 155 mm rounds. The most significant difference is in the round’s much-larger rocket, which testers want to ensure functions properly even when fired under extreme conditions. (Photo Credit: Mark Schauer)
