FS2004 – EC-505 Tiger ARH. The Tiger ARH (Armed Reconnaissance Helicopter) is the version ordered by the Australian Army to replace its OH-58 Kiowas and UH-1 Iroquois-based ‘Bushranger’ gunships. The Tiger ARH is a modified and upgraded version of the Tiger HAP with upgraded MTR390 engines as well as a laser designator incorporated in the Strix sight for the firing of Hellfire II air-to-ground missiles. Instead of SNEB unguided rockets, the ARH will operate 70 mm (2.75 in.) rockets from Belgian developer, Forges de Zeebruges (FZ). By Andreas Meyer.
