"In Harms Way"
Well written suspensful true story about the USS Indianapolis, the cruiser on a top secret mission that carried the Hiroshima A bomb form SF to Tinian island for its fateful B29 flight. Gets torpedoed and sunk by a Toyota driving sub commander and the effluent really hits the fan as those hungry sharks move in.
The 1st 4 pages grab you. And strangely, they occur in 1968.
