The Tomahawk cruise missile can carry a 150 kt W80 nuclear warhead. One is capable of turning a radius of 4 miles (a circle with an area of 50 square miles) into a raging firestorm killing almost everything inside that circle when used in airburst mode; or capable of destroying silo-based ICBM's or other buried targets when used in ground-burst mode.

There are currently 1,750 W80 warheads in service.

It's probably only a matter of time before these are placed somewhere in Eastern Europe if Putin keeps escalating his nuclear saber-rattling

In Aug 2019, the US conducted a test flight of a Tomahawk missile launched from a ground-based system. It was the United States' first acknowledged launch of a missile that would have violated the 1987 Intermediate-Range Nuclear Forces Treaty, from which the Trump administration withdrew on August 2, 2019 after Russia broke it first.
