HMS Bulwark was commissioned as a "Commando Carrier" on 23rd January 1960 at Portsmouth. So helicopters only.
Dates 1963-65 is a bit difficult.
Exercise Fotex65 involved Bulwark, HMAS Melbourne, HMS Victorious and HMS Eagle. So 1965, but where?
As to Seahawks, they were out of service by December 1960.
Shall continue to do some more "googling".
Ciarain.
