Update 4.602

Dear friends,

Today we’re releasing another update, 4.602, that brings to you two new aircraft at once. British Hawker Typhoon Mk.Ib is the first and it is available in Battle of Normandy Early Access now - this powerful, fast and heavily armed machine could handle a variety of combat missions. New tactical numbers and dynamic impact marks technologies already work for it and it has a wide array of modifications - another engine, propeller, gunsight, additional armor and dust filter.

The second star of the day is the late Great War German monoplane Fokker D.VIII, which also supports the new tactical numbers and hit marks technologies. Having the same engine as Fokker Dr.I triplane, but a much better aerodynamical profile, resulted in a significant boost in combat characteristics. The only wing of this airplane had an unusual design for its time - it had load-carrying skin made of plywood instead of fabric. Being a late war plane, Fokker D.VIII could be equipped with Oigee collimator gunsight and was armed with two 7.92 mm LMG 08/15 Spandau. It is now available to all owners of Flying Circus Vol.II.

Moreover, there are 20 new AI-controlled objects added in this update - they were developed for the Battle of Normandy. They are British in origin mostly, but there are additions for the US and Germany as well. Some of them are new types in our project - radars and reinforced concrete bunkers.
