"The first strategic deterrent patrol by a Fleet Ballistic Missile Submarine was made in November 1960 by the USS GEORGE WASHINGTON. The 3000th strategic deterrent patrol was made in April 1992 by USS TENNESSEE.

Fleet Ballistic Missile submarines have been deployed a cumulative total of 1024 ship-years since 1960. Submariners serving on Fleet Ballistic Missile submarines have acumulated nearly 90,000 man-years of submerged operations."
