The French 37 mm Model 1925 was useful for its original period but had only about 15 to 21 practical rounds per minute from each gun. A frequently quoted 85-round figure belonged to a twin mount firing both barrels, so it cannot be compared directly with single-gun rates. Later replacement by 40 mm Bofors and 20 mm Oerlikons also reflected difficulty obtaining French spare parts and ammunition. The gun's modest output was compounded by a wartime support problem. Separating gun, mount, and logistical performance explains why a headline firing rate can mislead.

Why the 37 mm battery fell behind
Practical firing rates, a misleading twin-mount figure, and later spare-parts and ammunition shortages explain why the 37 mm battery aged badly.
