Last Friday, March 8, the US Army announced the cancellation of its Extended Range Cannon Artillery (ERCA) program due to insurmountable technical challenges.

This decision marks a setback in the Army’s quest for enhanced long-range artillery capabilities.

Engineering Hurdles Plague ERCA Program

The Army is scrapping its new self-propelled long-range cannon program, ERCA, after running into many engineering problems during testing. Launched in 2018 with big promises, the idea was to beef up the Paladin howitzer with a super-long barrel that could fire farther than ever before.

The service subsequently built 20 practice cannons: two for destructive testing and the rest to outfit an entire battalion.

Unfortunately, the design had some kinks to work out, and the prototype cannons just weren’t holding up.

Picture this: they wanted to slap a 30-foot, 58-caliber gun tube onto the Paladin M109, allowing it to sling 155-millimeter rounds up to 70 kilometers (43.5 miles) away.

Sounds like something out of a sci-fi flick, right? Well, it didn’t quite pan out that way.

Prototyping Challenges Unveiled

The ERCA program hit snag after snag during development. They couldn’t get past the prototyping phase, which is never a good sign.
