The W66 thermonuclear warhead was used on the Sprint anti-ballistic missile system, designed to be a short-range interceptor to shoot down incoming ICBM warheads.

The W66 was a low-yield (details not declassified, but reportedly a few kilotons) warhead designed to destroy or disable an incoming warhead using neutron flux and, to a lesser extent, X-ray and blast effects.

The W66 was 18 inches (46 cm) in maximal diameter and 35 inches (89 cm) long, with a weight of approximately 150 pounds (68 kg).
