Answer the following question: Information: - The Martin Marietta Corporation was an American company founded in 1961 through the merger of Glenn L. Martin Company and American Marietta Corporation. The combined company became a leader in chemicals, aerospace, and electronics. In 1995, it merged with Lockheed Corporation to form Lockheed Martin. - In 1962 , the U.S. Navy issued a requirement for a long - range high - precision air - to - surface missile . The missile , named the AGM - 53A Condor , was to use a television guidance system with a data link to the launching aircraft similar to the system of the then projected AGM - 62 Walleye . - Guided Bomb Unit 15 is an unpowered, glide weapon used to destroy high-value enemy targets. It was designed for use with F-15E Strike Eagle, F-111 'Aardvark' and F-4 Phantom II aircraft. The GBU-15 has long-range maritime anti-ship capability with the B-52 Stratofortress. Rockwell International is the prime contractor for this weapon system. - The AGM-62 Walleye is a television-guided glide bomb which was produced by Martin Marietta and used by the United States armed forces during the 1960s. Most had a 250lb (113kg) high-explosive warhead; some had a nuclear warhead. The designation of the "Walleye" as an "air-to-ground missile" is a misnomer, as it is an unpowered bomb with guidance avionics, similar to the more modern GBU-15. The Walleye was superseded by the AGM-65 Maverick. Given the information above, choose from the list below the object entity that exhibits the relation 'manufacturer' with the subject 'agm-53 condor'. Choices: - eagle - lockheed - martin marietta - rockwell international
