America isn’t ready for Russia’s battlefield nuclear weapons
With an estimated 100,000 Russian troops positioned near Ukraine’s border and President Biden promising to assist Ukraine against a Russian invasion, the risk of nuclear weapons use is once again on the rise. During the Cold War, intercontinental ballistic missiles (ICBM), long-range strategic bombers, and submarine-launched ballistic missiles (SLBM) were the primary threat to human civilization. Today, however, it is Russia’s low-yield short-range battlefield nuclear weapons that pose the greatest nuclear threat.
Unlike strategic nuclear weapons like ICBMs and SLBMs, which have a range of more than 10,000 miles and yields above 150 kilotons, battlefield nuclear weapons are primarily short-range (less than 650 miles) and low yield (.1 to 20 kilotons). The Russians maintain an estimated 3,000-6,000 intra-theater nuclear weapons—many of which fall into this category. The United States, however, has no similar arsenal of battlefield nuclear weapons.
In recent years, Russian nuclear weapons were integrated into the nation’s defense posture in much the same way the United States integrated nuclear weapons into its defense of Europe during the Eisenhower administration under the New Look Policy. President Vladimir Putin’s comments concerning his willingness to use nuclear weapons confirm fears that he views nuclear weapons as usable weapons on the battlefield. …
Using the formulae found in Samuel Glasstone and Philip Dolan’s The Effects of Nuclear Weapons, some interesting results present themselves. First, if the Russians were to detonate their 10-kiloton nuclear weapon at a height of burst 587.6 feet above ground level, the ensuing fireball would not reach the ground. Thus, this “fallout free” detonation would not create the nuclear fallout zone that many Americans think results from a nuclear detonation. It would essentially result in a “clean” detonation.
Second, if the weapon were detonated above a rural area in front of advancing American troops, the prompt ionizing radiation (beta and gamma) released from the nuclear blast (deadly to humans) would dissipate within a radius of less than one thousand yards in less than a minute. This means exposed troops marching down a road could be very close to the detonation without receiving a harmful dose of ionizing radiation. If protected inside vehicles, buildings, or foxholes, the minimum safe distance from the detonation is even closer. ...
Advocates of arms control will certainly take issue with our suggestion that adversaries believe it is possible to contemplate the discreet and limited use of nuclear weapons, but the reality is that Vladimir Putin and the Russian leadership believe they have created an asymmetric advantage with their large arsenal of low-yield battlefield nuclear weapons. Denying and mischaracterizing the threat will not make it go away.
