One of the first major operations in which the ships were involved was Operation Eagle Claw launched by "Nimitz" in 1980 after she had deployed to the Indian Ocean in response to the taking of hostages in the U.S. embassy in Tehran. Although initially part of the U.S. Atlantic Fleet, "Dwight D. Eisenhower" relieved "Nimitz" in this operation after her service in the Mediterranean Sea. "Nimitz" conducted a Freedom of Navigation exercise alongside the aircraft carrier in August 1981 in the Gulf of Sidra, near Libya. During this exercise, two of the ship's F-14 Tomcats shot down two Libyan aircraft in what became known as the Gulf of Sidra incident. In 1987, "Carl Vinson" participated in the first U.S. carrier deployment in the Bering Sea, and "Nimitz" provided security during the 1988 Olympic Games in Seoul.
