It hosts high-level government and military delegations, as well as senior corporate executives around the world, while serving as a global event for leading aerospace companies and budding players (including start-ups) to make their mark in the international aerospace and defence market.
Formerly known as Changi International Airshow, the Singapore Airshow was launched as a partnership between Singaporean agencies Civil Aviation Authority of Singapore and the Defence Science and Technology Agency after the relocation of Asian Aerospace from Singapore. The event offers a unique platform for industry thought leadership through its high-level conferences, forums and co-located events. Leading industry players, government and military chiefs gather here bi-annually to contribute to dialogues, exchange ideas and seek solutions and strategies to advance the interests of the global aerospace and defence sector.
It is cited to be the third largest air show in the world after Le Bourget and Farnborough, as well as Asia's largest air show, although this is disputed by the Dubai Air Show.
