The 150-mm medium howitzer, sFH 13, has been provided with a self-propelled mounting, the
chassis of the French tracteur blindé 38L, made by Lorraine.
The sFH 13 is equipment of the last war, superseded in first-line units by the 15-cm sFH 18. Particulars
of the gun are:
|Caliber|| ||149.7 mm|
|Muzzle velocity||1,250 f/s|
|Maximum range||9,300 yds|
|Length of bore||17 cals|
|Number of grooves||36|
|Elevation||+5° to +45°|
|Weight of projectile||92.4 lbs|
The particulars of the mount 38L are: length, 14 feet; width, 5 feet 2 inches;
weight, 7 1/2 tons; engine, 70 horsepower; maximum speed, 22 miles per hour.
The sketch above shows the following details:
(a) A fixed gun-house of not very thick plate
(b) A limited traverse of not more than about 4 degrees
(c) A spade on the rear of the hull that can be let down to take recoil stresses.
It is notable that in this case an equipment firing a 92-lb shell to a maximum range
of 9,300 yards has been mounted on a hull weighing no more than 7 1/2 tons.
This is another case in which the Germans have utilized a standard field gun to make self-propelled
artillery. A recent picture shows another 150-mm howitzer, the 15-cm sIG 33, on a German Mark II
chassis with the gun on a special mounting built into the hull. There is a three-sided shield
no higher than the normal tank, instead of the very high box-like structure for
the self-propelled sFH 13.
