Precision-Guided Munitions: Background and Issues for Congress [Updated June 11, 2021] [open pdf - 2MB]
From the Introduction: "This report focuses on selected precision-guided munitions (PGMs) fielded by the Air Force, Army, Navy, and Marine Corps. Over the years, the U.S. military has relied on PGMs to execute ground, air, and naval military operations. PGMs have become ubiquitous in U.S. military operations; funding for these weapons has increased dramatically from FY1998 to the present as depicted in. In FY2021, the Department of Defense (DOD) requested approximately $4.1 billion for more than 41,337 weapons in 15 munitions programs. DOD projects requesting approximately $3.3 billion for 20,456 weapons in FY2022, $3.9 billion for 23,306 weapons in FY2023, $3.9 billion for 18,376 weapons in FY2024, and $3.6 billion for 16,325 weapons in FY2025. Congress, through the defense authorization and appropriations bills, has historically exercised its role in the decision to approve, reject, or modify DOD's proposals for PGMs. In addition, these programs pose a number of potential oversight issues for Congress. Congress's decisions on these issues could affect future U.S. military capabilities and funding requirements."
