RKSL Studios presents the WK450 Watchkeeper 450 Remotely Piloted Air System.UPDATED v3.112

The Watchkeeper WK450 is a Remotely Piloted Air System (RPAS) for all weather, intelligence, surveillance, target acquisition, and reconnaissance (ISTAR) use by the British Army.

It has a mass of 450 kg, a typical endurance of 17 hours, a payload capacity of 150 kg and uses a rotary Wankel engine. It can operate up to 150 km from the Ground Control Station (although multiple stations can be linked to extend the range). It was originally intended to enter service in June 2010, but years of delays, technical issues, hardware modifications, difficulties in training sufficient pilots and incidents means that it is not expected to be fully operational until late 2017.

QUICK NOTE: About Steam Workshop reuploads. We will remove any re-uploaded content. If you don't know there is a tool that crawls the Steam Workshop and matches files so even if you upload it for "Private/clan use" we will find it and we will issue a DMCA Take down request.
