I believe that brings total aircraft carriers near Iran to 3, and any subsequent fleet ships that go with them.

A new aircraft carrier strike group has entered the Arabian Sea and another is on its way, a Pentagon official said in a news briefing Wednesday — a shuffling of the U.S. fleet amid rising tensions with Iran.

Officials said there is no connection between the fleet movements and threats from Iran, however, the arrival of the USS Carl Vinson comes on the heels of Iranian military exercises in the Persian Gulf and threats to block the Strait of Hormuz, a major oil transit route.

And the killing of an Iranian nuclear scientist in Tehran on Wednesday further escalated tensions, as the Obama administration denied any role in the death.

The U.S. Navy announced Monday that the USS Vinson had arrived in the region to conduct missions in support of Operation Enduring Freedom, maritime security operations and theater security cooperation efforts.

“We will work closely with our regional partners to demonstrate our commitment to security and stability in the region,” Rear Admiral Thomas Shannon said in a written statement.

Captain John Kirby, deputy assistant secretary of Defense for Media Operations, on Wednesday denied U.S. involvement in the killing of the Iranian scientist and said the incident has not changed the U.S. position in the Gulf region.

And the number of carriers in the region “does go up and down, but it’s based on overall broad requirements in the region that the Central Command commander sets and establishes, [it’s] not necessarily … driven by a specific incident,” Capt. Kirby said.

The shift in naval assets in the region, Kirby said, is not linked to Iran’s recent threat to close the Strait of Hormuz, a threat made in response to the West’s sanctions on Iranian oil exports over the country’s contested nuclear program
