The Tankette reloadedThe tankette fad lasted until the late 1930s. At that time it was fast and quite cheap to bolster armored forces but of limited military value on the battlefield. So why choosing to resurrect the concept? The requirement of the Bundeswehr for a light, airborne, and all-terrain vehicle which can fit into most NATO aircraft cargos bays was part of it. It was considered for both transport and combat support for paratroopers, to be air-dropped, and to be airlifted by helicopters if needed. Porsche answered the call with several prototypes and a small series began in 1979-1983, later derived into two series. These are the only true modern "tankettes" in existence in western Europe and could be compared to some extent to the Soviet ASU-57.
The Wiesel 1The Wiesel I is built in light steel armor which can resist small arms fire. The general shape of the hull reminds early British light tanks of the Mk.IV-V series, with a narrow beak and large after section. The front section comprised the small transverse-mounted 64 kW Audi 2.1-litre 5 in line, turbodiesel engine which delivered 86 hp, the radiator and exhaust were at the left side and rear. Suspensions are made of torsion arms and shock absorbers, with four roadwheels on each side (one is the rear track tensioner). Two men can fit in, the driver and a gunner, using a remotely operated 20 mm quick-firing Rheinmetall MK 20 Rh202 in the standard Mk.I version. However other versions were tested and built in small series: The Wiesel 1 Aufklärung (recce), the Wiesel 1 ATM TOW (Anti-tank versions) armed with a single TOW launcher and reloads inside, later uprated with BMS. The Wiesel 1 Mk20 was upgraded with a new sight and BMS. 6 other prototypes were also tried. The Bundeswehr ordered 343 vehicles in 1985.
The Wiesel 2However similar in shape, the Wiesel 2 is an enlarged version, with five roadwheels on each side, longer (4.78 m), wider (1.87 m) and higher (2.17 m) or 15.7, 6.2, 7.1 feets.in. Overall weight was 4.78 tons (1083 ibs) in the heaviest version. The engine is a 1.9 L Volkswagen Straight-4 turbo-diesel with direct-injection delivering 109 hp (81 KW). The crew could be augmented to three. This vehicle saw several short series as the leichtes Flugabwehr System (LeFlaSys) air-defense light vehicle, Air Defence Command Post, Reconnaissance and Fire Control Vehicle (RFCV) with radar, and Air Defence Weapon Carrier (Ozelot) with four stingers or LFK NG missiles in vertical cells. For the army, there was also an ambulance, and Engineering Scout vehicle, a battalion command post vehicle, an Advanced Mortar System, with the sub-variants C2/JFSCT (command & control fire), 120 mm automatic laying weapon system and recce. 7 other variant prototypes were also tried. 178 were ordered by the Bundeswher.
Active serviceThe Wiesel ("Weasel") was named for its small size, speed and agility on the battlefield. It was a difficult target to spot visually and was light enough to be carried, four at a time in the cargo bay of a C130 Hercules or C160 Transall, and a Sea Stallion CH53 heavy helicopter can airlift two of them. Air-droppings were tested but abandoned after four failed tests. The deliveries took place in the late 1980s but the Bundeswehr eventually canceled the project due to budgetary restrictions, after 148 were delivered. Porsche continued the development however for the export market but so far none has been ordered abroad, although the United States bought seven Wiesel 1 of the unmanned version for evaluation. Nevertheless, the Wiesel saw active service with paratroopers units (Fallschirmsjägerbatallion) as organic support/antitank support to this day. This particular vehicle has been extensively deployed in airborne operations with UNOSOM II, IFOR, SFOR, KFOR, TFH and ISAF. It should be noted that seven Wiesel 1 has been lend to the US Army for unmanned robotic trials.
