Britain's supercarrier HMS Queen Elizabeth is wrapping up sea trials, but she has a long way to go before being battle-ready. First, she and her crew must test a brand-new fire fighting system, make a dramatic rendezvous with the USS George Bush, and team up with American pilots to train on the top-secret F-35 jet, the most advanced fighter ever built. Finally, she heads to her home port of Portsmouth for an emotional arrival and an appointment with someone no one ever keeps waiting: her royal namesake, Her Majesty the Queen.
