User: Note down some details about Munda Airport from the given text
Assistant: 1. Munda Airport in Solomon Islands' Western Province is a global airport with the IATA and ICAO codes MUA and AGGM.
2. Developed further by the U.S. Naval Construction Battalions 24 and 73 after its surrender. It was initially constructed by Japanese forces during World War II.
3. The airfield was converted to a commercial airport for regional flights after the war.
4. The field was considerably improved to become an international airport in 2015 as part of a New Zealand government aid and development project.
5. A significant amount of unexploded ordnance left behind by withdrawing US and Japanese forces was also removed as part of the refurbishment.
6. Despite the fact that no international flights were scheduled beyond 2019, the main economic goal of the improvement is to act as a backup field for international flights to Honiara International Airport, hence lowering fuel consumption and enhancing flight economics.
7. As an example, before the Munda improvement, an aircraft from Brisbane to Honiara required to have enough fuel on board to make a turn around and return to Brisbane, which was the closest practical alternative.
