Schwerer Zugkraftwagen 18 t with 8.8cm Flak
8.8 cm Flak 18 anti-aircraft guns were mounted on fifteen Sd.Kfz. 9s in 1940 as the 8.8 cm Flak 18 (Sfl.) auf Zugkraftwagen 18t (Sd.Kfz. 9) for anti-tank duties. The crew and engine compartments were lightly (14.5 mm (0.57 in)), but completely, armored, which limited the gun's ability to fire directly ahead. A platform with drop-down sides was fitted for the gun. Outriggers were necessary to brace the platform sides to support the weight of the gun crew.
The Famo half-track came into four versions; the standard version, a tractor with gun crew seats, second a tank maintenance version with an 6 tons crane, a recovery vehicle with a plate on its rear which functioned like a ground anker when pulling out stuck tanks or vehicles, and the last was a version with an 88 mm Flak gun in anti-tank setup. Around 2500 of these heavy 18t half tracks were made.
