If Yugoslavia is looking for a stop gab solution or has an immediate need for fighters, then the F-6E or the F-8C are the planes to choose.

The F-6E is in service with the RSAF for long and will be replaced by F-6H soon. Hundreds of planes are thus easily available for little money and the Swallow is still rated among the worlds finest fighters.

The F-8C is currently in production for the RSAF but orders for little over 400 planes will be fulfilled in summer 1939 so there easily is enough production capacity to answer Yugoslavian needs.

As a stop gab solution the older F-8B might suffice. The model is no longer in use with front-line units but reserve and training units still operate the aircraft until replaced. To ensure supply of airframes and spare parts many others have been parked on remote airfields, awaiting consumption as targets or scrap. It would be possible to deliver about 80 A/C and spare parts on short notice.

I'm not really sure what's stopping you from simply putting the F-6Es into deep maintenance and changing engines in order to bring them up to F-6H standard. It shouldn't be that hard. Lots of Spitfire marks were modified in that way. Even if the result isn't quite as good as a new-build aircraft, it's still probably better than getting rid of the old ones. Still, with a surge in wartime production you're going to be left with quite a few planes to get rid of.

Different engine, different coolers/wings, different cockpit layout and canopy.... Not sure if it is possible to upgrade the older E type. A hyprid is an option, probably for export, using the more powerful engine with the old fuselage and coolers.

I don't really see those changes being an issue. Even if it's a completely new engine it should pose too much of a problem. The Griffon fitted into the Spitfire without too many issues. Changing from a single ventral radiator to two wing radiators might be more an issue, still not impossible. Probably easier to make the ventral radiator deeper instead. I don't think there are many major issues there that would prevent it.

Focke-Wulf offers the Fw-190J (a version of the OTL Fw-190 A-4 armed with 2 7.92mm MG-17s and 4 15mm MG-151s) for Yugoslavian consideration.

What would be the probable delivery schedule for an initial quantity of 100 aircraft, with an option quantity of 100 aircraft?

Can the aircraft carry external fuel tanks?

Can customer-specified armament fits be accomodated in the design. The preferred armament would be six 13.2mm machineguns of indigenous design.

Delivery of an initial 100 aircraft could complete by June 30, 1940, with an additional 100 aircraft delivered by June 1941.

External fuel tanks or bombs of up to 500 kg can be carried on an underfuselage rack.

Armament could be changed, details of the proposed 13.2mm MGs would need to be exchanged with Focke-Wulf so placement options could be examined. Is the design suitable for synchronization, or not?

I have too ask?
Why down grade the armament on the "Foka"?

Standardization.

Project 220 is designed with a 13.2mm machinegun in mind; introducing the 15mm would require a whole new chain of supply, and it would be unique to one aircraft. Having two different calibers in one aircraft, without good reason , also complicates supply. As fas as the technical schools can turn our mechanics and armourers my resources in ground crew will be stretched thin for years.

Actually, the Bf-109As you already have are armed with the 15mm MG-151, each is armed with a pair of them mounted in the wing roots, along with the 7.92mm MG-17s in the nose decking. See the entry on the -109A in the German encyclopedia.

True, but looking to the future and the Fw190 replaces them... in any case, I have to look up the specs on the 13.2mm Machinegun and get them to you.

The M40 13.2mm Machinegun - which is presently still in the prototype stage but which should be available on schedule - is a reverse engineered variant of the Colt-Browning AN-M2, chambered for the Belgian FN Browning 13.2x96 cartridge. It can be synchronized, while free-firing is, of course, preferred.

Please advise if the weapon can be accomodated within the Fw190 airframe.

Thank you,

Browning designs, while they are synchronizeable, do not like being synchronized, taking a large hit in ROF to do so. This means that the nose and wing-root locations normally used for mounting weapons on the Fw-190 are not desireable locations for mounting Colt-Browning designs. That leaves the outer wing, where a pair of 13.2mm MGs could be mounted (replacing the outer 15mm MG-151), but there does not appear to be room in the wing structure for a third weapon there.

In these circumstances, the Air Ministry would accept the limitation of the armament to four 13.2mm MG

After exhaustive examination of the many proposals brought forward in response to its request, the Yugoslav Air Ministry has announced that it has entered into contractual discussions with the German Air Ministry and the Focke Wulf firm to obtain an initial quantity of 100 Fw190A fighter aircraft modified to Yugoslav requirements, with an option for an additional 100 aircraft. Deliveries of the first batch are expected to be complete by June 1940, and the second batch - should the option be exercised - by June 1941.

The Yugoslav Air Ministery has also entered into discussions with its German counterparts regarding the acquisition of a manufacturing licence for the BMW 801 series aero engine that powers the Fw190.

If that's what the customer wants, that's what the customer will get.

During the discussions regarding the BMW 801, the Yugoslav delegation also inquires regarding the acquisition of a licence for the BMW 132 as well as a quantity of 100 engines of that type, with delivery dates as early as can be arranged.
