U.S. Army Long-Range Precision Fires: Background and Issues for Congress [March 16, 2021] [open pdf - 2MB]
From the Summary: "Improvements to potential adversaries' artillery systems present a challenge to the U.S. military, the Army in particular. In addition to the challenge of improved artillery system capabilities and new employment techniques, the proliferation of special munitions--such as precision, thermobaric, and top-attack munitions--has renewed concerns about the potential impact of enemy cannon and rocket artillery on U.S. combat operations and ground combat systems. In response to this challenge, the U.S. Army is seeking to improve its ability to deliver what it refers to as long-range precision fires (LRPF) by upgrading current artillery and missile systems, developing new longer-range cannons and hypersonic weapons, and modifying existing air- and sea-launched missiles and cruise missiles for ground launch by Army units. Both the 2018 National Defense Strategy and the Army's Multi-Domain Operations operational concept call for improved Army LRPF capability to counter what has been described as Russian and Chinese anti-access, area denial (A2/AD) strategies designed to limit the freedom of movement and action of U.S. forces in both Europe and the Pacific region."
