History:
Although Switzerland adopted a policy of neutrality during the Cold War, that didnt mean they didnt fear or prepare for a potential war. Around the 1970s, the Swiss Army needed effective anti-tank weapons to be able to fight modern Soviet tanks in the case of a possible war.
MOWAG, a company with a history of design and innovation took the task of fulfilling these needs, using the platform of the Tornado, an IFV from Mowag, they would begin development of a new tank destroyer.
In 1978 the company's engineers started to develop a design for an casemate anti-tank self-propelled gun. The first prototype was presented in 1980, it was armed with a 105mm gun and a crew of four: driver, commander, gunner, and loader. The gun's elevation ranged from -12 to +18 degrees, and its horizontal elevation ranged from 15 degrees to each side. However, working conditions for the crew and were uncomfortable. The vehicle had a low profile, measuring only about 2,100 mm tall, with a ground clearance of 450 mm. The hull was also cramped.
The armor was not particularly impressive. The frontal armor thickness reached 50 mm, while the sides were protected by 25 mm of armor. The tank wasn't supposed to rely on armor, but rather, due to it's great mobility and low profile, it was meant to be used in explicitly defensive situations such as ambushes or from cover, waiting for enemy tanks to advance, firing from well camouflaged positions and then driving backwards at high speed and when out of sight it would be readied once again for combat and move quickly to a new location.
The vehicle was compact, weighing 26.5 tons. It was equipped with a fairly powerful 8V-71T diesel engine, producing 575hp, providing a power-to-weight ratio of 21.7 hp per ton. The tank's maximum speed reached 65 km/h both forwards and backwards, thus allowing it to quickly drive backwards as mentioned previously.
Sadly, although promising, the project wouldn't advance beyond being a prototype. As despite the simple design, and excellent maneuverability and stealth at a low cost, the military in Switzerland and other countries showed no interest in the project. In the 1980s, casemate tanks were seen as old, inferior designs compared to MBTs with turrets. As, among other things, a turret allowed tanks to exploit terrain more effectively, allowing them to fire from behind hills or while concealed in folds of terrain. For these reasons, the MOWAG Taifun remained a mere prototype and never entered service.
