Aircraft manufacturing is an important industrial sector in Russia, employing around 355,300 people. The dissolution of the Soviet Union led to a deep crisis for the industry, especially for the civilian aircraft segment. The situation started improving during the middle of the first decade of the 2000s due to growth in air transportation and increasing demand. A consolidation programme launched in 2005 led to the creation of the United Aircraft Corporation holding company, which includes most of the industry's key companies.
