Tank A Day Adventure - Flak 36: At the onset of Memorial Day weekend, I rode to the Collings Foundation's, newly-opened American Heritage Museum and spent some time photographing and obtaining information on each exhibit. Below is the 12th of these - the German Flak 36 heavy anti-aircraft gun. The Flak 36 is a German 88 mm anti-aircraft and anti-tank artillery gun from WWII. The word Flak is a contraction of the German word Flugzeugabwehrkanone (i.e., aircraft defense cannon) and became the generic term for ground anti-aircraft fire. Also known as the 'German 88 or 'Acht-acht' in German, the Flak 36 was one of the most recognized and feared weapons of the second world war. Some 20,754 of these guns and variants were made 1933 and 1945. It was designed by Krupp with Bofors of Sweden in the early 30s. The gun weighed 18,000 lbs., had a crew of 10 and could fire 15-20 rpm with an effective range of 26,420 ft. for anti-aircraft and 6,500 ft. for anti-ground. The gun was typically towed behind a Sd.Kfz. half-track, like the ones posted previously, and could be set up and ready to fire in minutes. It is believed that the Flak 36 and its variants downed over 6,000 allied aircraft during WWiI and damaged some 27,000 others. There is no estimate as the the number of tanks it destroyed. This particular 88 was built in 1943 at Skoda in occupied Czechoslovakia. Below is a video of the gun in action.
