UNDERSTANDING ARMY ACQUISITION


SOLID CORNERSTONE


New OTA seeks to speed capabilities to warfighters while also developing the U.S. industrial base.

sing the relatively new Cornerstone Other-Transaction Authority (OTA) provided the Project Manager for Combat Ammunition Systems (PM CAS) with two big gains: development of the vital XM1128 artillery projectile moved more quickly, and the indus-


trial base received a welcome boost.


Te XM1128, a 155 mm high-explosive extended-range unitary cannon projec- tile, has been identified as an important munition for Army modernization under the Long Range Precision Fires Cross-Functional Team. Long-range precision fires is the Army’s top modernization priority. Currently, the Army has requirements to deliver 155 mm ammunition that extends range from 22 kilometers to 30 kilometers, and the XM1128 projectile can meet that objec- tive. However, the process of ramping up availability of the XM1128 posed challenges for PM CAS, part of the Joint Program Executive Office for Arma- ments and Ammunition at Picatinny Arsenal, New Jersey.


Tere is a critical need for the capability to load, assemble and pack the XM1128, but there is no current capability in the industrial base to perform those tasks. Similar 155 mm projectiles—such as the M864 extended-range cluster muni- tion and M549A1 high-explosive, rocket-assisted projectile—have been out of production for decades. Against that backdrop, the use of the Cornerstone
