The Heeresflieger (Army Aviation) uses 3 main types. Heavy lift transport regiments are equipped with CH-53Gs which are esentially CH-53Ds. Other transport Regiments use the UH-1Ds ( built under licence by Dornier ?) while the anti-tank regiments use the Bo.105 although these are about to be replaced by Eurocopter Tigers.
The Bundesmarineflieger (Federal Navy Aviation) uses Westland Sea King Mk.41s and Westland Lynx
The Luftwaffe has staffels (squadrons) of UH-1Ds attached to its 3 C.160 Transall transport regiments and 3 AS.532 Super Pumsas/Cougars used for VIP transports.
The only kit of the Bo.105 came from Airfix while Revell Germany have announced a 1/72 Tiger kit to be released this year. Both the Sea King and Lynx are, or have been, available from Revell Germany. The AS.532 was available from Italeri
