demonstrator. Like the GoldenEye, this vehi- cle would carry a comprehensive multi-spec- tral sensor package, laser rangefinder/ designator and optional equipment for NBC hazards and mine detection. The payload and fuel is housed in a pair of twin pods on either side of the duct. BAE Systems Platform Solutions were selected to provide the third ducted fan VTOL Class II vehicle and a development contract was awarded by DARPA to all three teams on 6th December 2004. By mid-2005 DARPA had completed its initial trials and the BAE Sys- tems vehicle had been eliminated. Despite this, BAE Systems have continued to develop their OAV platform and at the present time the company has been testing a larger proto- type with an external duct diameter of 34in (86.4cm) enclosing a 28in (71.1cm) fan. This company-sponsored model features remov- able wings and carries sensors on a pylon above the duct. Most of the other leading con- tractors involved in this programme have continued to develop OAV class vehicles for various defence and security applications. The winning Class II OAV is expected to enter service with the US Army in 2014. Larger Class Ill designs will have an even greater range and payload capability. These vehicles are intended to provide support at battalion level. Right: Allied Aerospace 29-inch 2nd prototype UAV undergoing trials with Recovery Pen.
