Weapons Sales are presented as a Trend-Indicator Value based on the known unit production costs of a core set of weapons such as aircraft, air defence systems, anti-submarine warfare weapons, armoured vehicles, artillery, engines, missiles, sensors, satellites, ships and others. The indicator aims to represent the transfer value of military resources rather than the financial value of the transfer.
