The Navy didn’t say precisely where the ships were patrolling, but China has sought to extend its territorial sovereignty by building artificial islands in the South China Sea.
The two ships are on rotational deployments to U.S. Indo-Pacific Command, according to the Navy, and are conducting exercises with allied navies to provide maritime security and maintain a “free and open Indo-Pacific. ”
Littoral combat ships are fast, stealthy surface vessels capable of operating in the littoral regions of the world. The 400-foot-long ships carry a main cannon, missiles and two helicopters.
They are being built in two versions — monohull and trimaran — with a total of 40 planned. All of the trimaran ships will be based in San Diego.
