-8-H-Sv

In the Swedish military archives was found a letter from 8.9.1941 from the FAQ (BMM), (component of the Dnr MB3/H43), describing the design of the tank Praga V8H-Sv, with additional armour, and that offers its license production in Sweden. In addition to the detailed description of the entire vehicle (which roughly corresponds to the original design of the tank V8H) letter presents a diagram of the auxiliary armoring, as follows:

Front pancéř hull: 60mm (inclination of 30 ° from the vertical: 60mm
Front pancéř of the fuselage (slope of 60 st.): 20mm
Side top pancéř of the fuselage, side of the fighting compartment: 40mm
Side bottom pancéř hull: 30mm
Rear pancéř: 30mm

Front pancéř turret: 60mm
Side pancéř towers: 40mm
Rear pancéř towers: 30mm

High ceiling of the tower, and engine cover: 16mm
The other surface (the ceiling of the hull, turret): 10mm

Between the engine and fighting compartment is 3cm armoured bulkhead.

The dimensions of the vehicle:

Length: 5350mm
Width: 2500mm
Height: 2200mm
Sv.height: 40cm

According to the letter the vehicle is driven by eight-cylinder engine Praga "V8H" a volume of 14 liters and a power of about 240 to.with. in the range of 2000-2200 RPM. This machine weighs 20 tons (+/-8 percent) and reaches a speed of 40 km/h.
The folder also contained a variety of correspondence and details about licence production of the machine TNH-Sv in Sweden, unfortunately all in Swedish.

The documents for this type were sent to the Swedish Ministry of Defence on 25.9.1941. The Swedish commission led by Col. Gilbert and with the members of Maj. Holmgren, Ing. Forslund of Scania and retired Capt. Burman of Jungler visited BMM from 14.5.1942 to 16.5.1942. The Swedes for the license and the prototype to be built by BMM required that a Swedish Volvo engine be used, the top speed was to rise to 45 km/h, the specific ground pressure was not to exceed 0.6 kg/m2, the gun was to be of at least 75 mm calibre, and the tank was to have a third machine gun at the rear of the turret.
The 1939 prototype was demonstrated to the Commission, which showed decent performance. Ing. Forslund discussed with Ing. Surin about possible problems with the start of license production in the Swedish company Scania-Vabis. Jungler was to purchase a prototype to be built by BMM. The Swedes demanded comparative tests of the V8H-Sv with the Swedish Landsverk Lago type, and if the Czech tank won, the Swedish Ministry of Defence would reimburse Jungler for the cost of the prototype. Due to the progress in the development of the Swedish tank (Strv m/42), the interest in the V8H-Sv waned and was not finalized into a prototype. The Swedes were still negotiating to purchase a license for the Praga-Wilson reinforced transmission, but without success.

Diskuse

Dear,
a few words to this interesting project on the redevelopment of the chassis according to one of the patents Alexei Surina - see csl. patent no. 60230 from the year 1937.

Thanks to the publication of the drawing 1SPE2245 we now know that it was considered even for this variant of the chassis for the tanks V8H-Sv.

footnote
As far as I know, so factory FAQ made only two prototypes of tanks series V8H. The first was V8He (export), which was on the wishes of the csl. military administration rebuilt the V8H. The second prototype carried the designation V8Hz (zwei) and was constructed according to the requirements of the Wehrmacht. Both prototypes were equipped with traversing wheels of smaller diameter.

One of these prototypes was presented to the Swedish purchasing commission in 1942.

Correspondence with a colleague Silentstalkerem.
