 Reliable Replacement Warhead

The Reliable Replacement Warhead (RRW) was a program initiated by the United States in the mid-2000s aimed at developing a new class of nuclear warheads. The primary goals of the RRW program were to enhance the safety, security, and reliability of the U.S. nuclear arsenal without the need for nuclear testing, and to reduce reliance on legacy warheads that were aging and potentially less reliable.
