Ukraine's defense industry is organized around Ukroboronprom, a state owned conglomerate of over 130 companies. These companies include Soviet era giants such as Ivchenko-Progress aircraft design bureau that was opened in 1945, to newer companies such as RPC Fort which came into existence in the 1990s. Ukraine is also among the top 10 arms exporters in the world. The signing of recent large contracts may put Ukraine into 6th place among biggest arms traders, after the United States, Russian Federation, France, Germany and Israel. The output of Ukrainian defense plants grew 58% in 2009, with largest growth reported by aircraft builders (77%) and ship builders (71%).
