The aircraft carrier USS Carl Vinson arrived in Busan on Tuesday, the same day North Korea launched a satellite for the third time.
The Vinson docked here just over a month after the USS Ronald Reagan under an agreement signed by the leaders of the U.S. and South Korea in Washington in April to deploy U.S. strategic assets more often on the Korean Peninsula.
Last week, a B-52 strategic bomber was deployed to conduct a joint air drill here.
The Vinson is a Nimitz-class nuclear-powered aircraft carrier commissioned in 1982. It is 333 m long and 76.4 m wide and is being deployed here for the first time in six years.
The carrier's deck is densely packed with F/A-18 Super Hornet fighter jets, E-2C Hawkeye early warning aircraft and S-3A anti-submarine aircraft. The carrier strike group includes guided-missile cruiser Princeton and destroyers Hooper and Kidd.
