The National Aerospace Laboratory of Japan (NAL) was established in July 1955. Originally known as the National Aeronautical Laboratory, it assumed its present name with the addition of the Aerospace Division in 1963. Since its establishment, it has pursued research on aircraft, rockets, and other aeronautical transportation systems, as well as peripheral technology. NAL was involved in the development of the autonomous ALFLEX aircraft and the cancelled HOPE-X spaceplane.
NAL has also endeavored to develop and enhance large-scale test facilities and make them available for use by related organizations, with the aim of improving test technology in these facilities.
On October 1, 2003, NAL, which had focused on research and development of next-generation aviation, merged with the Institute of Space and Astronautical Science (ISAS), and the National Space Development Agency (NASDA) of Japan into one Independent Administrative Institution: the Japan Aerospace Exploration Agency (JAXA).
