The Polish defence ministry's armament inspectorate wants to buy six micro-unmanned air vehicle systems, to support the nation's ground troops.

Each system must include a ground control station and at least two air vehicles – which should be able to take off and land vertically – and carry an electro-optical/infrared sensor payload. Maximum take-off weight should not exceed 1.6kg (3.5lb), and its total diameter with rotor blades extended must be no more than 700mm.

Potential bidders have been given until 29 January to respond, with Warsaw to make a selection based on the key parameters of price (with an 85% weighting), and technical parameters (15%).

The Polish armed forces' modernisation programme for 2013-2022 calls for the purchase of an eventual 15 micro-UAV systems, via the "Wizjer” (Viewfinder) programme. Deliveries should be completed by 2017.
