The 19-year-old Crown Princess of Spain, who began her military training two summers ago, cut a striking figure in her crisp white uniform complete with black insignia.

The Spanish royal, 19, flashed an excited smile from onboard the Juan Sebastian ElCano on Monday, as she and her fellow students waved while the ship departed Santa Cruz de Tenerife.
