Rheinmetall has received an €83m contract from the nation of the Middle East and North Africa (MENA) region to provide Skyguard fire units.
The defence company said the new order brings the total, including services and spare parts, to €665m for the undisclosed country.
Earlier, the same nation has also placed orders worth €582m for Oerlikon Skyguard air defence systems.
Rheinmetall has recently booked new orders from a European country and an Asian nation to supply air defence systems under two different contracts with combined value of €50m.
The tried-and-tested 35mm Skyshield technology will defend public venues and critical civilian infrastructure such as power plants, dams and oil platforms from terrorist threats.
Rheinmetall has developed the Mantis air defence system, which recently entered active service, on behalf of the German Bundeswehr.
The company said that its advanced system protects military installations such as forward operating bases and other vital facilities from incoming rockets, artillery and mortar rounds.
Using Rheinmetall's air defence systems, radar systems and guns can be deployed and redeployed on mobile platforms at short notice in line with evolving mission requirements.
The company is planning to equip these systems with other effectors such as antiaircraft missiles and high-energy lasers, in the future.
Rheinmetall manufactures automatic cannon, integrated guided missile launchers and ahead airburst ammunition.
