Navy Columbia (SSBN-826) Class Ballistic Missile Submarine Program: Background and Issues for Congress [July 31, 2018] [open pdf - 1MB]
"The Columbia (SSBN-826) class program, previously known as the Ohio replacement program (ORP) or SSBN(X) program, is a program to design and build a new class of 12 ballistic missile submarines (SSBNs) to replace the Navy's current force of 14 Ohio-class SSBNs. The Navy has identified the Columbia-class program as the Navy's top priority program. The Navy wants to procure the first Columbia-class boat in FY2021. The Navy's proposed FY2019 budget requests $3,005.3 million in advance procurement (AP) funding and $704.9 million in research and development funding for the program. [...] Issues for Congress for the Columbia-class program for FY2019 include the following:  whether to approve, reject, or modify the Navy's FY2019 funding requests for the program;  cost, schedule, and technical risk in the Columbia-class program; and  the prospective affordability of the Columbia-class program and its potential impact on funding available for other Navy programs. This report focuses on the Columbia-class program as a Navy shipbuilding program. CRS Report RL33640, U.S. Strategic Nuclear Forces: Background, Developments, and Issues, by Amy F. Woolf, discusses the Columbia class as an element of future U.S. strategic nuclear forces in the context of strategic nuclear arms control agreements."
