On March 21, 1989, the USS Tennessee (SSBN 734) conducted the first undersea test launch of the Trident II ballistic missile off the coast of Florida. It did not go well..

Little known fact: I was serving aboard the older USS George Bancroft SSBN 643 and we had launched a Polaris V missile about a week or so before the Tennessee launched theirs off of Port Canaveral, FL. Our launch got no publicity but was a complete success and our missile named Janus missed it's target in the South Pacific by only 2 feet
