Mentoring and camaraderie are what hold the ship together. But life on deployment is stressful for everyone aboard, and there can be considerable friction between enlisted personnel and their superiors. Port calls allow sailors to blow off steam, but they don’t relieve all the pressure. In Guam, a young sailor coming to terms with his upbringing can’t play by the rules and is forced out of the Navy. From Guam, the Nimitz sails through the Straits of Malacca, past Singapore to Kuala Lumpur, the last liberty call before the long haul to the Persian Gulf.

After two months in the Gulf, one day starts to become indistinguishable from the next. The airwing still hasn’t dropped a single bomb, which is frustrating for some on board. The only relief comes from a port call in Bahrain, where some sailors relax by the pool, while others visit a mosque and learn about Muslim culture. The Princeton, one of the escort ships in the Nimitz strike group, loses a man overboard; an intense search to find the lost sailor ensues.

The last day in the Gulf is the last chance to drop bombs before the Nimitz heads home. The jets take off, laden with ordnance, and return hours later, still carrying the same bombs. As the Nimitz crosses the equator, the entire ship takes part in the Crossing the Line Ceremony, an ancient maritime ritual. In the middle of flight operations, a storm arises in the South Indian Ocean. The deck pitches violently, turning the already dangerous task of landing on the carrier into a nail-biting, heart-pounding drama.

This episode explores the many expressions of faith onboard the USS Nimitz: faith in self, faith in one’s shipmates, faith in the mission of the ship and the president’s call to arms. The major religious groups on board are Catholic and Protestant, but there also is a coven of Wiccans, as well as a Pentecostal group whose newest member is challenged by the duality of his beliefs and the temptations of liberty as the ship drops anchor in Perth, Australia.

A six-month absence places a heavy burden on relationships. The Navy holds seminars to counsel sailors on what to expect when they return home — and how to make the transition smooth. The “Tiger Cruise” ritual allows sailors to invite their family members aboard for the last leg of the deployment.

As the Nimitz makes its final transit from Hawaii to California, the sailors and Marines on board prepare to return to their homes and families. For those still on board, the “Tiger Cruise” provides a buffer, but there’s no such transition for those who fly home early from Hawaii. As the Nimitz returns to her home port of San Diego, sailors and Marines reflect on the deployment and take stock of what they’ve achieved. Was the mission accomplished? There are tearful, joyful reunions at the pier.
