The Flakpanzer IV Ostwind II is a rank IV German self-propelled anti-aircraft gun with a battle rating of 5.7 (AB/RB/SB). It was introduced in Update 1.91 "Night Vision", replacing the Flakpanzer 341 in the German tech tree.

The Ostwind II is an average SPAAG which definitely has nothing to look for on the front line, however, there is a great advantage with its double cannon which becomes extremely dangerous for enemy aircraft which fly within range.

The Ostwind II has sufficient penetrating power to destroy M18s or other light armoured vehicles, however, one should rather concentrate on enemy aircraft. The reasoning behind this is because the turret is open from above and weakly armoured on the sides and is vulnerable to enemy aircraft fire and the .50 calibre machine guns on vehicles such as the M2HB vehicle.

General info

Survivability and armour

The frontal hull armour (80 mm) is quite well protected against small-calibre weapons and .50 caliber BMGs, the sides (30 mm) and rear (20 mm) then again not.

The turret is open at the top and has a rectangular recess in the right, frontal turret armour, because of the optics.

In addition, the steel of the turret (25 mm) is very weakly armoured, as well as the hull roof (10-12 mm).

Since the vehicle has a crew of five, it usually survives the first attack from enemy aircraft (because of the driver and the machine gunner(/radio operator) in the hull), as well as a shot into the turret.


The vehicle does not have that great average speed, which means that the 39 km/h will be rare on the battlefield. Forget about trying to turn on the spot as this vehicle does not have neutral steering. Even worse is attempting to use the reverse gear (-7km/h) is extremely insufficient presenting an easy target if having to back out of a tight situation.

Usage in battles

Realistic Battles

The Ostwind II should be held in reserve towards the end of the game when there tends to be a significant amount of enemy aircraft flying. It is best to avoid the front lines or beating feet toward the enemy tanks as the Ostwind II tends to be an easy target for a majority of the other tanks in the game.

If your own team is about to lose or it gets very exciting towards the end and there are no many enemies left alive, you can place your Ostwind II inside an allied capture-point to defend it from enemy light tanks. Due to the location, it is more central to the battlefield and presents a difficult challenge for enemy aircraft to attempt to fly over.

Pros and cons


  • 2 x 3.7 cm FlaK 44 cannons
  • Does not need to reload until it is completely out of ammunition
  • Enough penetration to destroy enemy light armoured vehicles


  • Built on Panzer IV chassis and is a contemporary of it
  • Quite slow average speed
  • Inadequate penetration against many enemy vehicles (best against aircraft)


The Ostwind II was a development of the Ostwind. First conceived as early as October 1943, the Ostwind II saw the single 3.7 mm FLaK 43 replaced by a twinned 3.7 mm FLaK Zwilling 44 built by the Gustloff-Werke in Suhl. One single prototype was delivered to the Panzerflak-Ersatz und Ausbildungsabteilung Ohrsdurf/Thühringen in January of 1945 for evaluation purposes, but due to the rapid events of the war it was never taken into production.


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