Athena was a 1990s Lockheed Martin expendable launch system which underwent several name changes in its lifetime.
Development began at the Lockheed Corporation in 1993, where the design was known as the Lockheed Launch Vehicle. The name was subsequently changed to the Lockheed Martin Launch Vehicle when Lockheed merged with Martin Marietta. Late in the program's life, the name was finally changed to Athena, and all of the launches after the demonstration flight in August 1995 were conducted using that name. Athena was retired from service in 2001, but in 2010 it was announced that it would be put back into production, with launches set to resume in 2012.However, the project was halted in March 2017. In September 2010 Athena was added to NASA's Launch Services II contract. As of December 2017, no such flight has materialized
