In March 2020, U.S. Army Yuma Proving Ground demonstrated a dramatic stride in extending the range and precision of artillery fires in a demonstration attended by some of the Army’s highest-ranking officials, as well as members of the local and national media who watched both in person and via video feeds at the Pentagon and Fort Sill, Oklahoma.
The visitors witnessed two separate test fires of both the Excalibur precision guided munition and the XM1113 rocket-assisted high explosive projectile from a Prototype 0 XM 1299 self-propelled howitzer. Both Excalibur projectiles achieved a 65 kilometer precision hit, and both XM 1113 projectiles achieved a 65 kilometer range. The performance of the XM 1299, outfitted with a 58 caliber tube on a PIM chassis with loader assist, was the centerpiece of the test.
