Show TO DESTROY AN AIRSHIP. Big Oun Mounted on an Automobile Dealgned to Offset Fighting Fight-ing Air Crsft. Ilerlln The great urceaa of dirigible dirigi-ble balloons has created a demand for the Invention of means to destroy them In war time. Of these Ih fire) from rifle nnd machine guns waa not sufficient, on account of their amall caliber ond the difficulty of matching the moving nlrshlp. Cannon have) therefore been designed In Germany the greatest manufacturing country nf wnr material for the sole purpose of attacking and shooting balloons, flying machines, and Hie like. To do this effectively such a cannon must comply with the following reiulre-minta: reiulre-minta: rnllmlteil moving nhlllty aldewnya, shooting nt any angle up to lli vertical, highest speed of the pro-lectlle pro-lectlle or smallest time for Hying. In Th Airship Dstroyr, a. Mil Ion It must be possible to mova Hie gun from place to place In lha shortest time. The niilomnblle Illustrated herewith 1 compiles with these niHiiy nnd dim- , rult requirements. It tins been built '. by the famous Krupp concern nnd was exhibited In the recent Interna- lloiiul aero show nt Frankfort. Tho i fact thai tbe gun Is rather long far- f or a high accd for th projectile. ; Above It Is a brake with a lliiild nnd nlr compressor.
