He flew into Camp Bastion on Friday for what will be his second tour. He is scheduled to begin operations within 10 days in the country's Helmand Province. In 2007-08, he served in Helmand as an air traffic controller.
Cpt. Harry Wales, as he is known in the military, gave a thumbs-up after arriving on a troop carrier flight from England.
As part of the Apache's two-man crew, Harry will be both a co-pilot and the gunner responsible for firing the Apache's wing-mounted aerial rockets, Hellfire laser-guided missiles and 30mm machine gun.
The prince recently made headlines after he was photographed naked in a Las Vegas hotel room.
Next Saturday, the prince will celebrate his 28th birthday at Camp Bastion - but he won't be able to raise a toast with one of his beloved cocktails. The desert compound, which is next door to the U.S. military's Camp Leatherneck base, is an alcohol-free zone.
