Leonardo (formerly Finmeccanica) is the world’s 9th largest arms company, with arms sales of US$9.3 billion in 2015 (SIPRI). Its products include military helicopters, fighter aircraft, drones, missiles, naval guns, artillery and armoured combat vehicles. The company has sold drones to Pakistan, armoured vehicles to Oman and helicopters to Algeria, Libya and Turkey.
Leonardo is very much an Italian company, with the Italian Ministry of Economy and Finance owning 30.2%, but there is also substantial production in the UK and US. It owns what used to be Westland Helicopters, which became part of AgustaWestland and is now Leonardo Helicopters.
