Russia's defense industry employs 2.5 – 3 million people and accounts for 20% of all manufacturing jobs in Russia. Sevmash directly employs 27,000 people. The combined revenue of the industry's 20 largest companies in 2009 was $12.25 billion. Russian shipbuilders and naval missile manufacturers survived the difficult period of transition from a command to a market-driven economy, and kept skills needed for the development of advanced combat systems. With recently won orders for Project 955 and Project 885 submarines, the share of domestic military orders in Sevmash's portfolio has risen to above 70%.
