The Yugoslav Defence Ministry is inviting proposals for new heavy anti-aircraft artillery in the 75mm-105mm category. Commencement of deliveries within 180 days of contract award is required.

Japan can offer:

Type 90 75mm AA Gun


Type 14 10cm AA Gun


Info available in the Japanese encyclopedia here below the AT gun and the old 75mm AA gun.

German manufacturers can offer the 8.8cm FlaK 33 & 34, and the new 10.5cm FlaK 38.

I presume both would be mobile, or might the 10.5cm FlaK38 be only semi-mobile?

The FlaK 38 is more semi-mobile than mobile: it weighs about 10.5 metric tons deployed, compared to just under 5 tons for the FlaK 33. The Flak 33 is the historical FlaK 36, while the FlaK 38 is the historical FlaK 38.

Atlantis can offer the following:

75/1936
(Based on the 75mm Bourges M1936 AAG)
Projectile : 6.8kg
MV : 700m/s (2,296 f/s)
Range : 8000m Vert.
Weight : 3.8/5.8 tonnes
Elevation : -5 to +90
Traverse: 360deg.
ROF : 25rpm short term, 12rpm long
semi-automatic breech

Also, seeing as I'm waaaaay behind in news ect, Atlantis would also have a 90mm AA gun, very similar to the U.S. 90mm M1/M2/M3.

Please contact the chinese embassy for further informations.

Britain can offer the following;

Ordnance QF 3.7in Mk III, developed by Vickers partly as a private venture, firing trials began in 1936 and entered service 1937. It is based on a similar Naval AA gun. Weight in action is 9.2 tons mobile and 17.1 tons static, effective ceiling is 32-45,000 feet and ground range is 20,600-25,600 yards. Rate of fire is 25 rpm on the mobile mount and 19 rpm on the static mount. Elevation is 85 degrees on the mobile and 90 degrees on the static mounts.

Is the WW 3.7-in a true DP weapon like the OTL FlaK36? I see the specs for both static and mobile mounts; I presume they would have to be ordered separately.

If memory serves, the Mark II 3.7" guns exported to Bulgaria and Ireland are dual purpose of a sort, but the original mounts required enough time to set up that they were not as useful in the AT role as, say, the FlaK 36. (But allegedly they are better AA guns.) Again, if memory serves, Britain was developing a mount to permit that sort of DP performance (it just wasn't available when I bought.)

Given the passage of time, I am hoping that the lads in Sheffield have finished the job - it has an impact on the procurement decision.

According to what I read, it's capable of it, but with 2 caveats: 1, it's almost twice as heavy as the historical Flak 36, and 2, the carriage was not designed for low-angle firing and doing so would strain the mount and the recuperating gear. That said, though, an AP round was produced for it, but it was rarely used historically in the anti-tank role.

According to Wikipedia:

This was mainly because the 3.7-inch (94 mm) gun mobile mounting was almost twice as heavy as the German "88". Redeploying it was a slower operation, and the heavy AEC Matador artillery tractor normally used for towing could operate on hard surfaces only. Additionally, heavy AA Regiments equipped with the 3.7-inch (94 mm) gun were controlled by Corps or Army HQ, or at even higher level HQs, and command of them was not often devolved to the commanders at Divisional levels where the anti-tank role might be required. Prolonged firing at low elevations (not part of the original specification) also strained the mounting and recuperating gear.

Bascially the moblile mount is mobile with four wheels and outriggers for emplacing and firing and totally like the OTL British mounts.

The static mount is for fixed emplacements. We offer both depending on what roles the Yugoslav Army wants and where they want to put the guns. A static/ mobile mix makes sense if your covering airfields, depots, harbours etc.

There is a limited DP role but its not really designed for that in mind. If Yugoslavia wants a real DP gun mount then it will have to be a special export job and will take longer given mock-ups, prototyping and firing trials.

Humorously, the Belgians also have a 75mm AAG based on the Bourges, and also have been working on a 90mm AAG that is likely out by now, I'd have to check the start date for that though

You'll note the stats are remarkably similar.

75mm Bourges-FRC M1936 AAG
Based on a French Bourges arsenal design, improved by FRC. The design has a semi-automatic breech to allow rapid fire. The four wheel carriage is rubber tired and has outriggers to allow rapid deployment.
(Stats are a mixture with the 1932 Schneider)
75mm L54
Projectile : 6.8kg
MV : 700m/s
Range : 8000m Vert.
Weight : 3.8/5.8 tonnes
Elevation : -5 to +90
Traverse: 360deg.

After extensive consideration of the technical proposals submitted for review, the Yugoslav Ministry of Defence has selected the German 8.8cm FlaK33 as the Yugoslav Army's new heavy air defence weapon.

An initial quantity of 180 guns and their associated half-track tractors, service vehicles, and support equipment is required. The Ministry of Defence has entered into talks with the German Government regarding conclusion of a definitive contract for the procurement.
