In 1986, Bear responded to the Space Shuttle Challenger disaster by searching over 1900 square nautical miles (6,500 km²). During any given patrol, Bear conducts a wide-spectrum of missions such as search and rescue, alien migrant interdiction operations, counter-drug patrols, fisheries enforcement, and international engagement—illustrating the versatile, multi-mission character of the Coast Guard and the cutter fleet. Since her commissioning she has made 18 significant drug seizures involving 12 marijuana and 6 cocaine busts.
