Note: Note: | The MK 103 cannon was a high-performance weapon, but due to its considerable size and large weight, it was quite difficult (if not impossible) to install it in smaller fighters, such as Bf 109 K-4. This weapon was tested as a defensive, ie mobile cannon. Ammunition: APCR anti-tank missiles pierced the armor thickness. 42-52 mm at an angle of 60 ° for a distance of 300 m or 75-95 mm at an angle of 90 ° for a distance of 300 m. Explosive M-geschloss ammunition was made of high-quality thin-walled steel and a larger proportion of explosives. | The original specification for the MK 103 called for it to fit inside an aircraft's engine mounting (possibly as a Motorkanone, firing through a hollow propeller hub) , however, it proved to be too large and heavy to fit into small fighters like the Bf 109 K -4. APCR - Armor penetration: 1.65-2in/60 °/656 ft or 3-3.7in/90 °/656 ft. HEM - The mine shell is a particular form of HE shell was using a thin-walled steel casing of high tensile strength, a larger explosive charge can be used and reached a higher-detonation-power. |
