In 2017, the US Army established a collection of cross-functional teams (CFTs) aimed at rapidly pushing forward key technologies to advance the services’ next generation of capabilities. One of those teams was the Long Range Precision Fires “pilot,” an effort to develop the next generation of Army artillery—including “deep fires,” an artillery capability that can strike at strategic targets well within an adversary’s defenses.

That effort has spawned what Army Futures Command chief Gen. John Murray described to Congress last year as “the Strategic Long Range Cannon, which conceivably could have a range of up to 1,000 nautical miles” (1,150 miles, or 1,850 kilometers).

The Strategic Long Range Cannon program is now advancing through its first set of technical hurdles. Col. John Rafferty, head of the Long Range Precision Fires CFT, told Defense News in advance of this week’s Association of the US Army (AUSA) Annual Meeting that the Army wants to demonstrate a prototype of the gun system by 2023. Currently, the Army is working with the Center for Army Analysis and the Research and Analysis Center at White Sands Missile Range to confirm the technical feasibility of the cannon. The Army is preparing to perform early tests at Naval Support Facility Dahlgren, the site of the Navy’s test range for naval artillery.
