The Flakpanzer IV Sd.Kfz. 161/3 “Möbelwagen” (Eng: Moving van”) or 3.7 cm Flak auf Fahrgestell Panzerkampfwagen IV (sf) Sd.Kfz. 161/3, was a German self-propelled anti-aircraft gun used during World War Two, based on the Panzer IV chassis. It was armed with a 3.7 cm FlaK 43 L/89 anti-aircraft gun, capable of firing up to 150 rounds per minute, and had an effective ceiling of 4,800 meters (15,750 feet).
Powered by a Maybach HL 120 TRM V-12 gasoline engine producing 300 hp, it had a top speed of 38 km/h (24 mph) and a range of 200 km (124 mi). The vehicle featured four hinged armored plates around the gun, which could be folded down for a full 360-degree firing arc or raised for crew protection. While effective against low-flying aircraft, its open-top design left the crew vulnerable to enemy fire, and it was eventually succeeded by more advanced Flakpanzers.
The 3.7 cm Flak auf Fahrgestell Panzerkampfwagen IV (sf) Sd.Kfz. 161/3 in these pictures is on display at the Museum of Armored Vehicles in Saumur, France.
