The Ohio class was just coming on line in the early 1980's. My boat wasn't decommissioned until 1992 or 93. It served as a "slow attack boat" for its last few years afloat. Yes, we only had Poseidon C3 missiles onboard with MIRV warheads. Our sonar suite was a bit dated but we did pretty well with it. James, what do you know about boats? I served a 8 patrols on mine and we studied the Ruskies boats too. We even got within 10000 yards of one of their prototypes once. It was a noisy boat. Janes is a good resource but not perfect.
