Why the US must accelerate all elements of space-based nuclear deterrence

In recent years, robust dialogue and billions of dollars have been devoted to modernizing the nuclear triad, the three weapons systems that provide second-strike capability to deter adversaries from a nuclear attack on the United States. Yet, deterrence depends not only on a modernized triad but also on survivable systems for decision-makers to understand the nature of a nuclear attack, and to command and control the response.

Director of National Intelligence Dan Coats testified a few days ago: “Russia and China will continue to pursue a full range of anti-satellite weapons as a means to reduce U.S. military effectiveness and overall security.” Without reliable and secure surveillance and communications systems, our leaders may find themselves well-armed, but blind and dumb. A weakness in our nation’s sensing and communications systems undermines the entire deterrent.

The United States’ strategic “thin line” is the communications network, much of it spaceborne, that connects our nuclear weapons, sensors and related systems to the president and his national security team. It must be modernized and enhanced soon to maintain a credible deterrent against Russia and China. As the rivalry between the United States and these countries increases, with the one resentful of the loss of past superpower prestige, and the other committed to acquiring it, our nation needs a nuclear deterrent of which all its components are strong and resilient. China recently test fired another of its long-range, nuclear-capable missiles, the DF-26.
