Actually the Suez Canal was used by carriers up till the Six Day War thereabouts and then suspended until 1981. USS America CV 66 was the first carrier to transit the Suez again in 1981. Technically before that we really didn't have to have it because we had sufficient number of carriers. However all east coast carriers as far as I know or rather the super carriers from Forestall on made the transit around the Horn to get to S.E. Asia during Nam after the six day war.
Were you on board when it did?
That is correct. In 1979/1980 the Ike and our task group had to traverse the “horn” to go from Norfolk to Iran.
