It was commonly called a Self propelled A/T. The vehicle was powered by Maybach 'HL42TUKRM' petrol powerplant producing 100 HP which could drive the vehicle on roads at up to 38 mph with a range of about 200 miles before refuelling. Its cross country performance was good providing a max speed of about 19 mph and a range of about 100 miles. It was armed with 1 light machine gun , a 7.92mm MG 34. Its main armament consisted of a 3.7cm PaK 35/36 L/45 which could penetrate 44 mm of flat plate at 200 metres Armour Details Turret Front n/a Side n/a Rear n/a Top n/a Superstructure Front 10mm @ 30° (12mm) Side 8mm @ 35° (10mm) Rear 8mm @ 17° (8mm) Top n/a Hull Front 15mm @ 12° (15mm) Side 8mm @ 30° (9mm) Rear 8mm @ 45° (11mm) Top 6mm @ 90° (6mm) Armour (x)mm @ (y)° (Effective mm @ 0°) Effective Armour - Maximum 15 mm - Minimum 6 mm Weapon Details 3.7cm PaK 35/36 L/45 3.7cm Panzerabwehrkanone 35/36 L/45 (translates as Anti Tank Gun) History The standard German anti tank gun at the start of the war, had been tested in the Spanish Civil War, and numbers sold to Russia before 1940 Manufacturer Rheinmetal Manufactured 1935 - 1942 Calibre 37mm Length L/45 Rate of Fire 13 rpm Ammunition Details Name/Id Calibre Weight MVelocity Explosive Content 3.7cm Pzgr Patr 18 (AP Armor Piercing) 37mm 0.68Kg 762M/Sec Quoted Penetration 31mm @ 500mtr/30° ( ≈ 35mm/0°) Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.13 0.28 0.59 1.34 2.33 3.7 5.71 8.97 Penetration(mm@30°) 41 38 32 25 20 15 11 6 Penetration(mm@0°) 48 44 38 30 24 18 13 8 Hit Probability(%) 98 98 98 90 54 22 3 1 3.7cm Pzgr 40 (AP40 Armour Piercing Tungsten Cored) 37mm 0.35Kg 1020M/Sec Quoted Penetration 64mm @ 100mtr/0° Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.1 0.21 0.46 1.12 2.12 3.86 7.61 Penetration(mm@30°) 58 51 44 33 24 15 8 Penetration(mm@0°) 67 60 51 39 28 18 10 Hit Probability(%) 98 98 98 96 60 22 2 3.7cm Sprgr Patr (HE High Explosive) 37mm 0.61Kg 700M/Sec 0.025Kg explosive Maximum Range not shown as gun elevation is limited Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.15 0.3 0.64 1.46 2.54 4.03 6.22 9.76 Direct Fire Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.15 0.3 0.64 1.46 2.54 4.03 6.22 9.76 Hit Probability(%) 98 98 98 88 44 15 3 1 Blast/Fragmentation Effects Burst radius Infantry in open 99% kill 0 mtr Burst radius Infantry in open 66% kill 0 mtr Burst radius Infantry in open 33% kill 1 mtr  Armour Penetration inc roof at 1 mtr 0 mm An explosion within 0 mtr of infantry in the open will cause > 66% casualties and could damage some AFV's.

Hit probability is based on a static 2 x 2.4 metre panel at 0 degrees(vertical) at the range specified.

The data that has been used to create these records has come from Wikipedia, The Lone Sentry, The Bundes Archive and numerous books and websites that have provided the detailed information that has not been available anywhere else. The information we use to calculate the penetration tables, flight times and the hit probability comes from the Gun Calibre, the Shell Mass(Kg) and the muzzle velocity, plus range reductions to allow for gravity and wind resistance. This calculation originally came from a pre-war Krupp calculation which has been modified, and seems to fit the actual test results.
