    One for the Panzer nuts me thinks......Adam !


    I've just started reading ATB's 'Battle of the Bulge' and they refer to panzer regiment strengths/allocations of Flakpanzers namely the 'Wirbelwind' and 'Ostwind'. They also refered to flakpanzers in a similiar vain in 'Panzers in Normandy'.

    However they fail to mention just how effective they were at providing an effective anti-aircraft defence. Anyone know?

    That then led me onto the thinking about Germany's production struggling to produce armour and thought would it not have been more cost effective for them to manufacture more flak platforms like the Zugkraftwagen or the Flak variant on SdKfz 251 platforms instead of panzer platforms?

    I know this technically (From current British formations) would be classed as a mechanised vehicle in a Mech. formation rather than a armoured vehicle in a Panzer formation. But the Germans did seem to be cutting back in 1944.

    Cheers for your thoughts

    Andy,

    Here you go.

    Wirbelwind - Wikipedia, the free encyclopedia

    Wirbelwind/ Flakpanzer IV/2cm Vierling

    The Vierling (4 x 2cm cannon mount) was extremely effective and put up a concentrated fire against low flying planes.

    However when used against lightly armoured or soft skinned vehicles it could be deadly.

    The 251 halftrack had to be extensively modified just to accept a single 2cm flak cannon and so it made sense to use obsolete chassis to mount different weapons.

    There was no time to start complete new projects, so the Germans used what was at hand.


    Regards

    Cheers Tom,

    Point taken on the 251 but according to my source they were already producing Zugcraftwagons before the Wirbelpanzers and Ostpanzers.

    The above didn't come into service until Spring of 44 and prior to that the Germans were using the Sdkfz 161/3 'Mobelwagon' (Panzer III Platform).

    Andy,

    The Germans were good at utilising obsolete Tank chassis and producing Jagd panzers and the like.

    The Mk III panzer was the first so called heavy panzer that the Germans manufactured and was soon passed its sell by date and utilised for anything that was required.

    Although the Mk IV was in production until the end, when tanks were damaged, they sometimes came back in a modified form.

    Hence the hotch potch of vehicles towards the end of the war.

    Regards
    Tom

    As with anything it's not as straightforward as that. Aside from the reasons Tom Gives, no half-track is as capable as a full-track vehicle. Particularly when laden with heavy equipment. Mobelpanzer, Ostwind, Wirbelwind etc. could all keep pace with the Panzer units they were designed to protect in a way no half or semi track could hope to achieve.
    They could also keep the crew more protected than half-track variants, and allow for simpler full traverse. As a tank is (usually) designed with a central rotating platform in mind from day one then the chassis could already more easily offer the right centre of balance, space, power etc. There was also a steady flow of damaged tanks returning from the front that could be used in production of Flakpanzers (along with some new vehicles? would need to check that) without disrupting the supply of half-tracks or other tanks too badly.

    On effectiveness; as with the allied multiple 'light' AA mounts, later in the war the ethos was more one of putting an attacking pilot off his aim than genuinely hoping to shoot him down with 20mm & 37mm weapons with relatively crude direct sighting. No doubt planes were lost to these machines, but genuinely effective AA fire lay with the heavier guns. No harm in throwing up as much lead as humanly possible when under air attack though.

    On effectiveness against ground targets - 4X20mm cannons blatting away would be a boon in any encounter wouldn't it?

    Sdkfz 161/3 'Mobelwagon' (Panzer III Platform).
    I think all 'Mobelwagens' (removal van) were on Pz. IVs...161/3 certainly was.
    would have to reread some stuff on these vehicles to get more clarity though.

    Andy,

    Link showing the Sd Kfz 161/3

    Sd.Kfz.161-3 Flakpanzer IV or Mobelwagen 1943

    Flakpanzer IV Mobelwagen (Sd.Kfz.161/3)

    The reason it was developed in 1943 was that the short barrelled 7,5cm weapon of the Mk IV was totally inadequate in late 1942 against the Russian T34 Tanks.

    The T34 could stand off at 1200 to 1500 metres and destroy the Mk 1V with ease.

    The Mk IV with the short 7,5 cm cannon could only penetrate the side armour and frontal armour at 400 metres.

    A member of the legion and Ex Bundeswehr Tanker had a father who was a Major and tank commander in Russia and was captured in December of 1942 north west of Stalingrad as the 14 Panzer regiment were decimated by the T34's.

    The German tactics had to dangerous as several tanks had to expose themselves in order to attract the T34's into a trap where other German Tanks, hidden on both flanks were waiting to hit the T34's side on. The German bait in the slot was lucky to survive.

    The rest is history, the 14th German Panzer Division failed to exist after December 1942 and those who did survive were assimilated into other units.

    Under these type of circumstances if the outdated tanks could be modified into something useful they were.

    Regards
    Tom

    As far as i know the Wirbelwind Vierlings Flak was designed by and first used on the Panzer IV Chassis by SS Panzer Regiment 12 , HJ , they also used a single 20cm Flak gun on a 38 T chassis,

    regards

    Looking in Spielberger ~

    A hotch-potch of SP AA gear was lashed up from 1942 onwards using whatever was to hand. Disliking these makeshifts Hitler requested a study in October 43 into vierling 2cm ,(& in 1944 3.7mm) mountings on full-tracks to attempt to improve the official set-up of these machines so that they could be given the best sights etc.

    There's a regular problem that seems to crop up with the names of these things.
    Mobelwagens are the fold-down slab-sided ones, carried assorted guns.
    Ostwind is the single 3.7 mounted in a rotating turret.
    Wirbelwind is the 4-barreled 'Vierling' variety.

    Wirbelwind as we know it was shown to Guderian by the firm of Ostbau in May 1944, he selected the design over others presented and it went into immediate development by Daimler Benz, assembled by 'Ostbau' in Silesia, and later at Teplitz. I'd guess the SS vehicle Paul mentions was a similar device, but not officially a Wirbelwind.
    I've a suspicion we've got a picture of it on here, but can't find the damned thing. Ah, may have been thinking of this T34 one that cropped up here.

    Do you recall when this SS mounting was done Paul?

    I think one of the big lessons of the 1941 campaigns was the need to provide armour for SP guns of all types. Hence why the unarmoured half-track/Flak 38 combo didn't look so hot anymore.

    All the best

    The Sturmartillerie (the guys with the StuG) tinkered together their own Flakpanzer in 1945 by fitting refurbished MkIII chassis with slightly modified "biscuit tins" (Wirbelwind-turrets).
    It is said that almost a dozen of these were built shortly before the end of the war. Actually, 90 pieces were to be mounted, but this failed because there were not even enough steel sheets left at that time.

    If you add up the totals of Mobelwagens, Wirbelwinds and Ostwinds produced then divide that by number of Panzer Divisions the result is a very small number. That is the real reason they weren't effective; there were never enough.

    Not an AA-tank but an armoured half-track; Sd.Kfz. 251/21 - Schützenpanzerwagen (Drilling MG151s). Anti-aircraft and ground support variant equipped with a triple-mount of MG151 autocannon; early version being MG151/15 mm cannon
