On February 14, 2008, U.S. officials announced plans to use a modified SM-3 missile launched from a group of three ships in the North Pacific to destroy the failed American satellite USA-193 at an altitude of 130 nautical miles (240 kilometers) shortly before atmospheric reentry.
Officials publicly stated that the intention was to "reduce the danger to human beings" due to the release of toxic hydrazine fuel carried on board, but in secret dispatches, US officials indicated that the strike was, in fact, military in nature.
A spokesperson stated that software associated with the SM-3 had been modified to enhance the chances of the missile's sensors recognizing that the satellite was its target, since the missile was not designed for ASAT operations.

On February 21, 2008 at 03:26 UTC, the Ticonderoga-class guided-missile cruiser USS Lake Erie fired a single SM-3 missile, hit and successfully destroyed the satellite, with a closing velocity of about 22,783 mph (36,667 km/h) while the satellite was 247 kilometers (133 nautical miles) above the Pacific Ocean.
USS Decatur, USS Russell as well as other land, air, sea and space-based sensors were involved in the operation.
