M1299 Self-Propelled Howitzer

The M1299 Self-Propelled Howitzer is an American 155mm turreted self-propelled howitzer currently being developed under the Extended Range Cannon Artillery program. It is planned to entered service in 2024.

The Extended Range Cannon Artillery (ERCA) program was designed to produce a self-propelled howitzer system with longer range and rate of fire compared to the existing M109A7 Paladin. Increased range and accuracy is accomplished by having a longer 58-caliber gun as well as employing the XM1113 rocket-assisted artillery shell. The howitzer is expected to eventually incorporate an autoloader that could increase rate of fire to 10 rounds per minute.
