The US Army is assembling its first four Extended Range Cannon Artillery (ERCA) prototypes at Picatinny Arsenal in New Jersey, and anticipates using at least one of the weapons during the upcoming ‘Project Convergence 2021' exercise.

Brigadier General John Rafferty, the head of the Long-Range Precision Fires Cross-Functional Team, told Janes on 9 July about the ongoing effort to field an incremental upgrade to BAE Systems' Paladin M109A7 self-propelled howitzer, which includes a 58-calibre, 30 ft (9.1 m) gun tube that is designed to launch 155 mm rounds out to 70 km.

To date the service has been test firing an early version of the weapon that it dubs the XM1299 prototype zero.
