a6 revisted... the REAL story.

The Focke-Wulf 190 A-6 was developed to address shortcomings found in previous "A" models when attacking U.S. heavy bombers. Modifications of the type to date had caused the weight of the aircraft to creep up. To combat this and to allow better weapons to be installed in the wings, a structurally redesigned lighter, stronger wing was introduced. The normal wing armament was increased to four 20 mm MG 151/20E wing root and outer wing cannon with larger ammunition boxes while retaining the two MG 17 fuselage machine guns. New electrical sockets and reinforced weapon mounts were fitted internally in the wings to allow the installation of either 20 mm or 30 mm (1.18 in) ammunition boxes as well as for underwing armament. Because the outer wing MG 151s were mounted lower than the MG/FFs, new, larger hatches incorporating bulges and cartridge discharge chutes, were incorporated into the wing lower surfaces. It is believed the fuselage MG 17s were kept because their tracer rounds served as a targeting aid for the pilots. A new FuG 16 ZE radio navigation system was fitted in conjunction with a FuG 10 ZY. A loop aerial for radio navigation, mounted on a small "teardrop" base was fitted under the rear fuselage, offset slightly to port, with an additional short "whip" aerial aft of this. These aerials were fitted on all later Fw 190 variants.
