Flak 40 zwilling 1-35

Açıklama

The 12.8 cm Flak 40 was a German anti-aircraft gun used in World War II. Although it was not produced in large numbers, it was reportedly one of the most effective heavy anti-aircraft guns of its era. Development of the 12.8 cm Flak 40 began in 1936, with the contract being awarded to Rheinmetall Borsig. The first prototype gun was delivered for testing in late 1937 and successfully completed testing. The gun weighed nearly 12 tonnes in its firing position, which meant its barrel had to be removed for transport. Limited field testing showed this was impractical, so in 1938 other solutions were considered. Ultimately, the firing platform was simplified, based on the assumption that it would always be securely bolted into concrete. The gun fired a 27.9 kg (62 lb) shell at 880 m/s (2,900 ft/s) to a maximum altitude of 14,800 m (48,600 ft). Compared with the 88 mm Flak 18 and 36, the Flak 40 used a powder charge four times as large.
