The San Diego-based littoral combat ship USS Mobile joined a Philippine warship in a freedom-of-navigation mission in the South China Sea last week, the Navy reported.

The mission took place July 31 inside the Philippines’ exclusive economic zone, which is challenged by China.

The Mobile sailed with the Philippine Navy’s Gregorio del Pilar-class patrol ship BRP Ramon Alcaraz.

“We welcome the opportunity to conduct maritime activities alongside our allies from the Philippines,” said Capt. Justin Harts, commander of Destroyer Squadron 15. “Sailing together demonstrates commitment to our continued coordination with the Philippine Navy.”

China has threatened claims by the Philippines and other countries to island and economic zones in the South China Sea.
