U.S. modernizes nuclear triad
The United States should maintain the nuclear triad's viability and modernize it as an effective deterrent against Russia's upgraded weapon, deputy undersecretary of defense for acquisition and sustainment Alan Shaffer said, according to U.S. Department of Defense website.
"Consistent with the National Defense Strategy, the effort's highest priority is maintaining the nuclear triad's viability and modernization of the nuclear triad as an effective deterrent," Shaffer told the House panel.
"Whether it is Russia or China upgrading their nuclear forces with new and advanced nuclear weapons, threats from weapons of mass destruction continue to evolve, modernize and expand," Shaffer added.
The triad refers to the three categories of nuclear delivery systems: land-based intercontinental ballistic missiles, submarine-launched ballistic missiles and strategic aerial bombers.
