Officially known as the Thunderbolt III, this missile was more commonly known as the Screamin' Demon.
Designed in the days preceding the collapse of the Soviet Union the Thunderbolt was designed to lay waste to the Russian countryside without the need for explosive or nuclear weapons. The lack of such weapons made it possible to build (and theoretically use) such a weapon without breaking any specific weapons treaty.
The Thunderbolt was essentially a massive airbreathing rocket with a sharp tipped nose. It used the air rammed into its intakes to feed a combustion chamber powered by liquid hydrogen. Smaller rockets were used to propel the thunderbolt up to speed, and stored liquid oxygen was used to power it when it did not have the speed to force enough air into the engine.
The Thunderbolt carried no usual weapons. It's only means of attack were it's sharp wedge shaped nose and blinding speed. At velocities approaching Mach 3.5 (3.5 times the speed of sound) and flying low enough above the ground, the Thunderbolt produced shock waves of immense power.
These waves shattered glass, tore apart wood framed houses, deafened people miles away, and animal tests suggested it could kill people standing under the flight path via internal hemorrhaging.
Thirteen Thunderbolt missiles were built, but the project was canceled in 1997 by Senator Perkins who called the missile "A despicable weapon that preys upon noncombatants and provides no real military asset other than terror."
The program was quietly scuttled until 2009 when the remaining 11 missiles were rebuilt with cameras, smoother noses, and improved stealthiness to serve as reconnaissance aircraft. Their speed proved to be essential to the information gathered during the wars in Columbia in the 2010's and were never even detected. Even their sonic booms were quieted by coke-bottle body shaping and smoother noses.

You know what's funny? I just really wanted to draw clouds. Anyways, the above is made up, though it is very informed by science and history. I also really had a hankering for crazy realistic weaponry. Gotta put my supersonic flow classes to use!
You mean like a bunker buster? Alas, it probably wouldn't do very well as at destroying specific targets, the engine type I used would be efficient but very delicate and it would probably blow itself up before it got deep enough to do enough damage.
