The 10.5cm le.F.H 18/2 Gw II(A,B,C,F) was a Self Propelled Artillery vehicle designed in 1942, manufactured by FAMO, it was based on the fully tracked PzKpfw II chassis and was in use from 1943 to 1945. It was commonly called a Wespe. |

It was commonly called a Wespe.
The vehicle was powered by Maybach 'HL62TR' petrol powerplant producing 140 HP which could drive the vehicle on roads at up to 25 mph with a range of about 138 miles before refuelling. Its cross country performance was good providing a max speed of about 12 mph and a range of about 55 miles.
It was armed with 1 light machine gun. Its main armament consisted of a 10.5cm le.F.H 18/2 L/26 which could penetrate 125.4 mm of flat plate at 200 metres
Slightly lengthened Panzer II chassis with the engine moved forward with a number of redesigns over the Panzer II. This was a very successful design and was used in most theatres of war. | |

About Penetration Figures
All penetration figures in this database are calculated to a common standard
based on German WWII testing criteria (complete penetration with functioning fuze).
This allows direct comparison between all nations' guns.
Original national test figures would be higher for some nations due to different criteria:
- German: 1.00? (baseline - strictest)
- British: 1.02? (slightly looser)
- American: 1.05? (50% mass through plate)
- Soviet: 1.10? (75% mass through plate)
For example, a Soviet gun showing 159mm here would be published as ~175mm in Soviet documents,
and a German gun showing 120mm would be published as 120mm in German documents.
The 159mm figure is directly comparable to the German 120mm - the Soviet gun really was more powerful.
|
| National Testing Standards |
|---|
| German: | 1.00? - Complete penetration, fuze functions (strictest) |
| British: | 1.02? - Complete penetration |
| American: | 1.05? - 50% of shell mass through plate |
| Soviet: | 1.10? - 75% of shell mass through plate |
|
All database figures are normalized to German standard for direct comparison.
Multiply by the factor above to see original national test figures.

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.
