Ultritium

Ultritium is an extremely powerful chemical explosive, virtually undetectable by conventional sensors and therefore frequently employed in covert operations.

Ninety isotons of enriched ultritium had enough explosive power to vaporize almost all matter within a radius of 800 kilometers (just under 500 miles).

• In 2346, Kira Nerys, brought to the past by the Orb of Time, planted a bomb made from ultritium resin aboard Terok Nor in an assassination attempt on Gul Dukat.

• In 2365, a pair of Antedean assassins posing as a diplomatic delegation attempted to bomb a conference on Pacifica using ultritium. Their plot nearly succeeded, were it not for Ambassador Lwaxana Troi, who read their minds.

• An ultritium-based auto-destruct device was used to destroy a Romulan scout ship in 2366.

• The Dominion mined ultritium from a rocky gas giant's moon.

• The Jem'Hadar employed ultritium concussion shells to bombard a downed Jem'Hadar attack ship captured by Captain Benjamin Sisko in early 2373.

• During the Dominion War, an undercover team led by Captain Sisko destroyed a Dominion storage facility using enriched ultritium, concealed inside an empty canister.
