Baghdad West Aerodrome, which would later be known as Al-Muthanna Airport, was the first principal airport of Baghdad. The new airport was to be located 10 and a half miles southwest of the Al Muthanna Airport. Work began on the airport in August 1965 due to the older Baghdad West Airport declining in passenger numbers due to its lack of facilities, and the runway (now Runway 15R/33L) and apron had been completed by early 1966. An interim passenger building was to be completed initially, before the construction of a larger airport terminal, and when the new terminal would be completed, the interim terminal would be converted into a cargo terminal. Originally, the airport was supposed to be completed by 1968. The airport cost £15-20 million. The interim terminal contained a restaurant and 2 floors, airline offices, a combined transit and departure lounge, an arrival lounge, customs’ halls and a large concourse. At ground level, the terminal had an area of 43,000 square feet. The newer terminal was to have a single pier handling 8 aircraft, and the interim terminal, now a cargo terminal would have 5 extra aircraft parking stands next to it. The airport complex was to have 25 buildings and facilities, such as the main terminal, the Iraqi Airways headquarters, the control and communications building, and the cargo terminal once the plan would be fully completed. The control and communications building was to be located 3,300 feet northwest of the terminal. It would be a two-story building with a central tower containing the control room. The HQ of Iraqi Airways was to have 8 floors consisting largely of offices and two single-story units, one of which containing a staff canteen and kitchen while the other having welfare facilities. A massive hangar built for Iraqi Airways would be built, it would be built from reinforced concrete with giant cantilever beams and have an area of 54,000 square feet. It would have multiple workshops and stores together with all the necessary process shops for the maintenance and servicing of modern aircraft. An Iraqi Airways operations wing would also be built as a two story building. Meanwhile, a 3 lane highway was built to access the airport and the entire project was the responsibility of the Iraqi Director-General of Roads and Bridges. All of these facilities would make the airport capable of being one of the best in the Middle East. Sir Basil Spence designed the never built permanent terminal with 8 gates as a Consultant Architect for the engineering firm Sir Alexander Gibb & Partners. A Romanian state enterprise, Technoexport, was involved in performing all the main contract work other than the radio installations and the electronics. The plans for the permanent terminal with 1 pier with 8 aircraft gates was cancelled and shelved, but the original illustrations of both the interim terminal and the terminal are archived. The illustrations were made in 1967. The building would have been a rectangular block with a huge canopy porch and large pyramid-shaped skylights. A distinctive crescent-shaped sculptural motif with square-patterned tiles on its underside was planned for the roof. Spence was interested in adapting ancient forms of Sumerian writing to achieve a texture on the walls of the airport. He wanted the interior to be largely of luxurious marble stone but by 1969 was concerned that due to spiralling costs this might have to be abandoned in favour of local materials. Contrary to popular belief, in January 1970, the airport opened as Baghdad International Airport with one 10,827 foot concrete runway (now 15R/33L). The airport handled 26 airlines in 1978 and was the main base of Iraqi Airways, the IATA code was BGW and the ICAO code was ORBB. The new terminals were developed under a consortium led by French company Spie Batignolles under an agreement made in 1979. The Iran–Iraq War delayed full opening of the new airport terminals until 1982.
