The Flakpanzer I Ausf. A is a rank I German Self-Propelled Anti-Aircraft (SPAA) vehicle with a battle rating of 1.3 (AB/RB/SB).

General info

Survivability and armour

The Flakpanzer I does not have good survivability, unlike the Panzer II, III, and early IV models. It has only two crew and is hull breakable, so it generally gets knocked out by any incoming shot. Even 7.5-8mm machine guns can kill a Flakpanzer frontally. It is also hull-breakable, so early-game HEAT spammers are your nemeses.


The mobility of the vehicle is decent to good for the tier, at 31kph forward and 6kph backward. Power-to-Weight ratio is reasonably good at 10.36hp/ton fully upgraded. It is responsive when steering on most terrain, though snow can be troublesome at times.


Main armament

The Flakpanzer I is armed with the FlaK 38 (20 mm), which is a fantastic gun for the tier. It boasts a high fire rate, 20-round clips, useful HE to shred low-flying planes, 46mm pen AP-I, and 64mm pen APCR. The gun will shred most enemies it can encounter with the APCR belt, even though it is only half APCR.

Usage in the battles

The Flakpanzer I is extremely versatile, but due to nearly nonexistent armor, it is best used as a flanker and tank-killer with situational use against unaware planes. The mounting of the gun is VERY wobbly, so do not expect to be able to do quick reaction shots in surprise encounters. Turret traverse is very fast, however, allowing it to react fast when not moving to new threats not immediately aware of its presence. While it CAN spray at targets, it is adviseable not to spray most of the time because the reload between clips is rather long and punishing for the tier.

While the gun is great, there are some enemies it encounters that you should straight-up avoid if at all possible. These are the Valentine MkI, B1 bis, and B1 ter. If used in 1.7 lineups, the Matilda MkII, T-28E, and M3 Lee/US Grant I/UK Grant I/RU M3 Medium are also significant threats. It can kill the B1 bis, T-28E, and M3 Lee variations in some situations, but the B1 ter, Valentine, and Matilda are totally immune even to the APCR belt outside lucky turret ring hits.

Pros and cons

Summarize and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a bulleted list. Do not use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - they have a substitution in the form of softer "inadequate", "effective".


  • High penetrating gun for tier
  • Fast turret traverse
  • Mobile enough for tier
  • Responsive handling
  • High Fire Rate
  • Large Clip Sizes


  • Long Reload b/t Clips
  • Gun is insufficient against the more armored opponents
  • Nonexistent armor and survivability due to two crew and hull-breakability
  • Many things are faster than it
  • Vulnerable to surprise-strafing from planes


Describe the history of the creation and combat usage of the ground vehicle in more detail than in the introduction. If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/historical reference" (example: https://wiki.warthunder.com/Name-vehicles/historical reference) and add a link to it here using the main template. Be sure to include links to sources at the end of the article.

In-game description

In early 1940, the ordnance logistics department directed the Alkett and Daimler-Benz companies to develop a weapon mount with a circular field of fire, to be mounted on the chassis of the Pz.Kpfw. I Ausf. A tank. The outdated chassis was used since the Germans were intensely seeking alternative ways to use chassis.

The Flakpanzer I had a hull, engine, transmission, and chassis which were similar to the Pz.Kpfw. I Ausf. A tank. In the modified turret box, in the place of the dismantled old turret, a 20 mm 2 cm Flak 38 gun was installed on a platform. The gun had an operational fire rate of 220 rounds per minute and allowed the tank to effectively engage low-flying targets. This gun's vertical angle could range from -10 to 87 degrees.

A total of 24 of these self-propelled anti-aircraft guns were built. Two more were built with 2 cm FlaK 30 guns. All of the Flakpanzer I guns which were released were used by the 614th flak battalion, which fought on the Eastern Front at Stalingrad. The guns were often used for direct fire support for ground troops, firing against ground targets.

One of their flaws was that trajectory calculation was cumbersome. In order to compensate for this, folding metal sides were added, but they did not do much to remedy the situation. Therefore, attacking ground targets required 5 people, but anti-aircraft fire required a crew of 8. The anti-aircraft vehicle was protected by nothing but its front armor. Most of the ammunition was placed in a specially designed Sd.Ah.51 trailer. Communication between vehicles was carried out using signal flags, since the radio equipment had been dismantled. The vehicle's biggest advantage was that the 20 mm anti-aircraft guns could be dismantled and installed on a platform towed behind the vehicle. These dismantling and installation procedures took 4 and 6 minutes, respectively.


An excellent addition to the article will be video guides, as well as screenshots from the game and photos.
