Nazi Flak Towers Blasted Allied Bombers
Many Allied bombers shot down in flames by anti-aircraft fire from one of the handful of Nazi Germany’s Flak Towers
(If you have forgotten: the technique of firebombing used so successfully against many German cities was developed by the German Luftwaffe for their long campaign of aerial firebombing of London in the early years of the war)

Most of these young gunners were fifteen or sixteen and were known as the kinderflak
The main function of the towers was less shooting down individual Allied bombers than to put up such a mass of anti-aircraft fire as to hinder bombing attacks on the area immediately around them. Flak, a word used by both sides, is the abbreviation of the German word Fliegerabwehrkanone, which translates as “air defense cannon.” They would literally put up a curtain of flak bursts in front of the bomber stream so bombers had to fly through it.
Had to Fly Straight and Level on their bomb runs
The Germans began the wholesale bombing of cities in WW Two starting with Warsaw moving on to Rotterdam and subsequently every major city in Great Britain and Northern Island. London was especially hard hit. During the Blitz on London, the Germans bombed the city 57 nights in a row, killing thousands and starting massive fires which often were so big they could not be controlled by the London Fire Brigade.
On their bomb runs bombers had to stay straight, level, and in strict formation for a few minutes. This meant the bombers were flying wingtip to wingtip with other bombers just above and others just below. This was done to minimize the time over the target.
The batteries fired pre-set “box barrages” to create a curtain of flak
The batteries fired pre-set “box barrages” to create a curtain of flak which British Royal Air Force or US Army Air Force bombers would have to fly through on their bomb run. Shells were set to explode at different heights usually above 20,000 feet. The strategy was to force the bombers higher since the higher they were when they dropped their bombs the less accurate the bombing. (Although under the best conditions bombing was rarely accurate).
British Royal Air Force bombed at night
Additionally, while these photographs were all taken in daylight, the British Royal Air Force bombed at night. So the other reason to force the bombers above 20,000 or so feet was to put them in the path of German night fighters. When a spotlight caught a bomber, the point was to illuminate the bomber for the night fighters. Nonetheless, various anti-aircraft batteries in Berlin, for example, would open up. This often led to German flak batteries shooting down their own night-fighters.
German Fighter Command made regular complaints to the anti-aircraft command to stop doing this and toward the end of the war demanded that the gun captain of any battery which fired above its mandated ceiling be tried and shot.
Three such towers were built in Berlin, three in Vienna, and two in Hamburg
Three such towers were built in Berlin, three in Vienna, and two in Hamburg. Each tower actually consisted of two towers: the very large gun tower known as the ‘G-Tower’ and a smaller fire-control tower located nearby known as the ‘L Tower’. The fire control tower transmitted the targeting values to the gun tower by wire – that is telephone/telegraph wire – that was buried deep below ground in a concrete tunnel to protect the wires from being severed.
Towers had large bomb shelters for civilians. Ceilings of the shelters were painted with luminescent paint so those in the shelter weren’t completely in the dark if power knocked out.
In addition to serving as platforms for anti-aircraft guns, each G Tower had a large bomb shelter for civilians. These shelters were designed to accommodate thousands of civilians, a hospital, workshops of various sorts, and Wehrmacht command posts. Each tower had an independent supply of electricity and water as well as barracks and offices for the Luftwaffe personnel who operated the tower and the guns. In the Third Reich, all anti-aircraft defense was the responsibility of the Luftwaffe. If the power were knocked out, the ceilings of the shelters were painted with luminescent paint so you weren’t completely in the dark.
April 1942. One of the main gun platforms of the Zoo Tower, most famous of all the flak towers. Shells were kept in the heavy steel ready-use ammunition locker at right and carried to guns by a squad of men as seen above and right. Because the gunners were out in the open on the platforms without protection from bomb splinters or the shrapnel from their own anti-aircraft shells casualties were often heavy.
Zoo Tower the Most Well Known
Towers Designed by Albert Speer
The Zoo Tower was the first one to be built and was located by the Berlin Zoo in the center of city and was meant to protect the key government buildings. During bombing raids on other parts of Berlin, Speer used to watch them from the top of the Zoo Tower. The tower was destroyed by the British in 1946. It was located in what is now the aviary section of the Berlin Zoo.
Although the zoo was destroyed during the war with most of the animals being shipped to other cities or shot by the army, it was rebuilt in its original location which is very close to where the Kurfürstendamm ends at the Tiergarten.

Towers Almost Indestructible Which Is Why So Many Still Exist
The towers were almost indestructible with the walls on each tower being 2.5 meters thick or 8 1/2 feet of solid concrete. The towers could – and often did – survive direct hits by Allied bombs. Because these were such massive structures, many of them remain since no one can figure out how to dismantle them without wrecking an entire neighborhood. I think the surviving towers are an important part of the history of WW Two and should be preserved.
The best, and to my knowledge, the only book devoted to the towers is The Flak Towers: In Berlin, Hamburg and Vienna 1940-1950 by Michael Foedrowitz. The book was translated from the original German. The research is impeccable. The author worked almost exclusively from primary sources as well as interviewing the leading expert on the towers.
