The National Museum of Naval Aviation was originally finished in June 1963. As the popularity of the museum grew, so did the need for more space to accommodate the collection and restoration of historical naval aircraft. Museum directors commissioned architect, Paul K.Y. Chen, and structural engineer Franklin Harwood of Harwood Associates, to design a new museum. to be completed in1975.
The first new addition to the new museum provides a massive main entrance to two exhibition halls that stand 200-foot by 200-foot by 50-foot high. Adjacent to the exhibition halls is an atrium building measuring 100-foot by 100-foot. Each of the buildings was designed to be capable of integrated expansion for later additions and future planning.
