Warfare Specialist Able Seaman Gosling, paying his first visit to the USA, said: "In one day I saw the 9/11 memorial, Times Square, and the Empire State Building. I'll never forget this."
Engineering Technician Chapman added: "You can't get a better run ashore really. We were picked up from the ship in one of those massive American SUVs and driven to the tourist spots.
"My favourite was Times Square. Walking around in my uniform felt a bit strange but everyone we spoke to was lovely. I even got a free Starbucks!"
HMS Queen Elizabeth set sail for the US from Portsmouth on 7 September in place of her sister ship HMS Prince of Wales which broke down off the Isle of Wight days before the trip.
