Race riots aboard Navy ships carrying weapons of mass destruction.
Imagine that. On U. S. Navy ships, oil tankers and aircraft carriers, racial unrest rose to the level of riot. Black sailors trying to hurt white sailors; white sailors trying to hurt black sailors; sometimes these riots happened at sea during Vietnam wartime operations. Most of this racial unrest occurred from 1970 to 1976.
I served in the U.S. Navy from June 1972 to March 1976. In fact, as a sailor with Air Anti-Submarine Squadron 27 (VS-27), I was on board the USS Intrepid (CVS 11) during the race riot of January 1973. 5,000 men, on a ship carrying warplanes and tons of munitions; while at sea there were some black sailors and some white sailors randomly attacking each other by race.
