General info

Survivability and armour

Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.


Write about the mobility of the ground vehicle. Estimate the specific power and manoeuvrability, as well as the maximum speed forwards and backwards.

Main armament

Main article: FlaK43 (37 mm)

Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: {{main|Name of the weapon}}. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons


  • Never need to reload
  • Very little lead required to hit enemy aircraft
  • Reasonable rate of fire for the calibre (37 mm)
  • A single hit often cripples or completely destroys an enemy aircraft
  • An M18's worst nightmare
  • Rather difficult to kill with one shot
  • Turret is better armoured than the Wirbelwind


  • Based on the chassis of a 4.0 tank; here the armour lacking and is slow moving
  • A viewing port in the turret allows enemies to kill the gunner with machine gun fire
  • Open turret; susceptible to aerial gunfire or bomb blast shrapnel
  • Significantly harder to hit and kill an enemy aircraft when compared to the Wirbelwind
  • Pz. Gr. belt no longer has 65 mm of penetration; combat ability is debatably worse than the Wirbelwind


Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

In-game description

A development of the Wirbelwind project. The goal of the Ostwind project was to increase the unit’s firepower, protection, and effective range. For this purpose, a 3.7 cm FlaK 43 anti-air gun was installed on it, and its turret’s armor was increased to 25 mm. The first prototype was completed in September, 1944. In the same month, on the 23rd, it was used in combat operations on the Eastern Front. Between 1944 and 1945 Ostbau-Sagan released 43 mounts. They were more effective than their predecessors had been.


Excellent additions to the article would be video guides, screenshots from the game, and photos.
