After the Cold War ended with the collapse of the Soviet Union in late December 1991, requirements for such surveillance declined. In 1993, "Indomitable"s SURTASS gear was removed, and she received an AN/SPS-49 radar for use in counternarcotics surveillance. In her new role for counter narcotics patrol she deployed for two missions per year starting September 1993. As well as her civilian crew, she embarked 18 Navy personnel to operate her sensors and coordinate with authorities. For her first five missions she averaged 300 days underway per year operating in the Caribbean Sea and Panama Canal area.
