About

Building on its century of know-how, Washington is 'the state' for U.S. aviation and aerospace. There are more than 1,300 companies in the supply chain, serving the needs of every major aircraft manufacturer and airline in the world. Established businesses and fast-growth startups are building on this legacy of innovation, exploring new frontiers in commercial space, electric propulsion, air mobility, uncrewed aerial systems and new energy sources such as hydrogen. To encourage additional industry growth, the state offers aviation and aerospace companies an array of incentives, including reduced or deferred tax credits and tax exemptions.
