British officials say Prince William has arrived in the Falkland Islands for a six-week deployment as a search and rescue helicopter pilot.
The Defense Ministry said Thursday William landed on the British outpost as part of a four-member Royal Air Force crew.
His visit has riled Argentina, which claims the islands 290 miles (460 kilometers) off its coast that it calls Las Malvinas.
The two countries have been trading barbs in the run-up to the 30th anniversary of Argentina's April 1982 invasion. The 10-week war that followed ended in British victory and killed 650 Argentine troops, more than 250 British personnel and three islanders.
Britain still maintains about 1,000 troops in the territory, whose 3,000 residents overwhelmingly wish to remain British.
