At 11/8/63 meeting Robert McNamara relays a conversation he had with Admiral Rickover
“I talked to Rickover in connected with this nuclear carrier and while we were discussing it, he said, ‘You know that Anderson was absolutely insubordinate during the Cuban Crisis. He consciously acted contrary to the President's instructions. I just thought you'd be interested. Rickover told me 10 days ago."
President Kennedy: "I wonder what he means.."
McNamara: "Well I didn't want to probe too much, I didn’t want to have a discussion but, I just was – he was objecting, Rickover said enough to let me know that Anderson was objecting to the instructions that you and I were giving relating to the quarantine and the limiting of action in relation to stopping the Russian ships."
President Kennedy: "He wanted to sink a ship."
McNamara: "He wanted to sink a ship. That’s right."
