Anti Aircraft Weapons....

[Soren]

Well the proximity fuze has to do with the ammunition, not the gun.

How about the 128 mm "Zwilling"?

Hi Stitch,

>[...] and why they moved on to the Ostwind, which did have a larger-caliber cannon (3.7 cm), but only had one barrel and, therefore, a much lower rate of fire.

The 37 mm cannon could engage targets at longer ranges than the smaller calibres, making it a better choice for a Flak supposed to protect other units as the protective envelope was larger.

Henning (HoHun)

I agree with HoHun. And 37mm was more effective against Il-2s. Also maybe in the Westwind turret there might have been too little room to fast changes of magazines, after all they hold only 20 rounds, with 450 cyclic rof they didn't last long.

Very effective, but also very heavy and cumbersome, and the RoF wasn't very high.

 

[Lucky13]

Right....cheers Soren!

For shipboard Cannons, I'd go with the 5"/38. Usually grouped in sets of two, at least later in the war, with a rpm of 15, per gun. Coupled with the proximity fuse, it was deadly.

Images of an 8,8 cm Flak 18 used by the Waffen SS Totenkopf in July 1941 ostfront, tipical of this weapon the gun is performing other than AA task, in this case long range artillery.

 

[Erich]

nothing on the 3.7cm Zwilling > ?

oh the shame

 

[Soren]

I thought I mentioned the 3.7cm Zwilling and its much greater firepower comared to the 40mm Bofors.

 

[Juha]

BTW the monster QF 3.7 inch Mk VI AA gun had a ceiling of over 15000m.

I admit that as an AA gun I thought that the 3.7in was a better weapon than the 88 Flak 36. It fired a heavier shell, to a greater effective altitude, with a better rate of fire and a proximity fuze.

A powerful combination

 

[Erich]

Soren maybe we are talking the same weapons system then again maybe not ..........this along with the 4-barrel 2cm Flakvierling was the scourge of Allied A/C

 

[Theo]

The Bofors 40mm is still used in the AC-130 gunships and is pretty much the same weapon from ww2.

 

[CharlesBronson]

BTW the monster QF 3.7 inch Mk VI AA gun had a ceiling of over 15000m.

Hmm, dont think so, the muzzle velocity wasnt high, at list not so high as other heavy AAA of the time.

Charles
check for Mark VI, it's a different gun, 3.7in loose liner with RD Rifling into 4.5 inch Mk 2 body
RD meaning that muzzle end was smooth bore. Put on 4.5" AA gun carriage. It was a big bastard and was built only as static version.

Oh, I see, sorry I have no data of that in my Ebooks folder .

IIRC, there were two soldiers on each side of the turret responsible for loading two of the cannons each, and one gunlayer in the center of the turret, right behind the mount.

Just found out something very interesting: the planned successor to Wirbelwind and Ostwind was a version armed with "four 30mm MK103/28 or MK103/38 guns, capable of firing 1600 rounds per minute. In December of 1944, Ostbau produced only one prototype designated Zerstorer 45 (Destroyer 45) - 3cm Flakvierling MK103/108 auf Sfl PzKpfw IV. Same concept was incorporated into rearming of the Ostwind with two 37mm Flak 43 or Flak 44 guns or 30mm Mauser MK103 cannon. In January of 1945, Ostbau was able to produce one prototype designated Ostwind II (3.7cm Flakzwilling 44 auf Sfl PzKpfw IV) , while 100 were ordered. In 1945, it was decided to utilize obsolete at the time PzKpfw III and mount it with Wirbelwind (designated as 2cm Flakvierling 38 auf Slf PzKpfw III) or Ostwind (designated as 3.7cm Flak 43 auf Slf PzKpfw III) turrets, designated as Flakpanzer III. 90 were ordered but the end of the war terminated the production.Eventually, all of Flakpanzers were to be replaced by newly designed Flakpanzer IV Kugelblitz in the early 1945." (from the website "Achtung Panzer").

I myself made a mistake, the original tube was 4.5inch, corrected that in the original message.

The 88mm FlaK 41 has a ceiling of 15000m as-well.
