Navy Frigate (FFG[X]) Program: Background and Issues for Congress [Updated June 8, 2020] [open pdf - 3MB]
From the Introduction: "This report provides background information and discusses potential issues for Congress regarding the Navy's FFG(X) program, a program to procure a new class of 20 guided-missile frigates (FFGs). The Navy's proposed FY2021 budget requests $1,053.1 million (i.e., about $1.1 billion) for the procurement of the second FFG(X). The FFG(X) program presents several potential oversight issues for Congress. Congress's decisions on the program could affect Navy capabilities and funding requirements and the shipbuilding industrial base."
