The U.S. Navy has dispatched a small armada to the South China Sea.

The carrier John C. Stennis, two destroyers, two cruisers and the 7th Fleet flagship have sailed into the disputed waters in the last 24 hours, according to military officials. The carrier strike group is the latest show of force in the tense region, with the U.S. asserting that China is militarizing the region to guard its excessive territorial claims.

The Stennis deployed from Washington state on Jan. 15.

The stand-off has been heating up on both sides. After news in February that the Chinese had deployed an advanced surface-to-air missile battery to the Paracel Islands, U.S. Pacific Command head Adm. Harry Harris told lawmakers that China was militarizing the South China Sea.

"In my opinion China is clearly militarizing the South China Sea," Harris testified on Feb. 24. "You’d have to believe in a flat Earth to believe otherwise."

A 7th Fleet spokesman downplayed the heavy U.S. presence in the region.

"Our ships and aircraft operate routinely throughout the Western Pacific — including the South China Sea — and have for decades," Cmdr. Clay Doss said in a statement. "In 2015 alone, Pacific Fleet ships sailed about 700 combined days in the South China Sea."

However, experts say sending Stennis and its air wing to the South China Sea is a clear signal to China and the region.

"Clearly the Navy and (Department of Defense) is demonstrating its full commitment to presence and freedom of navigation in the region,” said Jerry Hendrix, a retired Navy captain and analyst with the Center for a New American Security in Washington, D.C. “With the full carrier strike group and the command ship, the Navy is showing the scope of its interests and ability to project presence and power around world.”

Navy challenges China, others in South China Sea

The destroyer Lassen's October patrol within the 12-mile limit of China's manmade South China Sea islands was the first challenge of China's sovereignty over the Spratly Islands since Chinese land-reclamation projects began there.

On Jan. 30, the destroyer Curtis Wilbur patrolled near Triton Island, part of the Paracel Islands chain China also claims.

Six nations in the region lay claim to parts or all of the disputed islands chains. The Spratly Islands, a collection of reefs, rocks and other natural features, have been the site of extensive Chinese land reclamation projects. In the last two years, China has begun constructing islands on top of reefs and claiming territorial seas around them to gain exclusive fishing and resource rights to most of the South China Sea.

These disputes have led to violence in the past. In 1974, a conflict between South Vietnam and China led to a shootout in the Paracel Islands, located between Vietnam and China's Hainan Island. That dispute continues.
