Hitler looking at the Gustav gun.
In 1941, German steelmaker and arms manufacturer Krupp A.G. built Hitler the "Gustav Gun," the largest gun ever used in combat, according to Military Channel's "Top Secret Weapons" documentary.
The four-story, 155-foot-long gun, which weighs 1,350 tons, shot 10,000-pound shells from its mammoth 98-foot bore.
Here's what the gun looked like when fired:

In the spring of 1942, the Germans debuted the mighty "Gustuv gun"at the Siege of Sevastopol. The 31-inch gun barrel fired 300 shells on Sevastopol.

However, as the Nazi's would soon find out, the ostentatious gun had some serious disadvantages:
- Its size made it an easy target for Allied bombers flying overhead
- Its weight meant that it could only be transported via a costly specialized railway (which the Nazi's had to build in advance)
- It required a crew of 2,000 to operate
- The 5-part gun took four days to assemble in the field and hours to calibrate for a single shot
- It could only fire 14 rounds a day
Within a year, the Nazi's discontinued the "Gustav gun," and Chen notes that Allied forces eventually scrapped the massive weapon.
