The Philippine Navy's World War II-era warship BRP Rajah Humabon is anchored during the navy's founding anniversary celebration at a naval station in Cavite city, west of Manila on May 25, 2015 with buildings along Roxas Boulevard in Manila in the background.

The Philippine navy is one of the weakest in the region relying mostly on decades-old, surplus US warships.

The Philippine government has been modernizing the navy and other branches of the armed forces in the face of China's increasing aggressiveness in trying to claim most of the West Philippine Sea.
