Luxembourg has become the fifth customer for the Airbus Helicopters H145M, with an order for two examples of the multirole medium-twin.
Deliveries are due to take place before the end of 2019, with service entry to follow in 2020. The pair will be used for "defence and security missions", the company says.
No details of the contract value have been disclosed, but the deal also includes a training and support package.
Germany was the first customer for the latest variant of the 3.7t helicopter and received its final example from a 15-unit order in 2017. The rotorcraft has since also been ordered by Hungary, Serbia and Thailand.
Airbus Helicopters says it has now secured orders for 51 H145Ms.
