Navy Constellation (FFG-62) Class Frigate Program: Background and Issues for Congress [Updated September 29, 2021] [open pdf - 2MB]
From the Introduction: "This report provides background information and discusses potential issues for Congress regarding the Navy's Constellation (FFG-62) class frigate program, a program to procure a new class of 20 guided-missile frigates (FFGs). The Navy's proposed FY2022 budget requests $1,087.9 million (i.e., about $1.1 billion) for the procurement of the third FFG-62, and $69.1 million in advance procurement (AP) funding for the fourth and fifth FFG-62s, which are programmed for procurement in one or more future fiscal years. The FFG-62 program presents several potential oversight issues for Congress. Congress's decisions on the program could affect Navy capabilities and funding requirements and the U.S. shipbuilding industrial base."
