The Soviet Union was a country of unconventional solutions and mysterious acronyms. One of these, SOZSA, stood for the Stavropol Experimental Plant of Specialized Vehicles. It produced, among other things, vehicles for transporting shift crews to remote sites. It was the specialists at this plant who, in the 1980s, seized upon the idea of creating a special-purpose vehicle based on the UAZ-3303-01.
Thus, in 1986, an original vehicle with a high passenger compartment and large sliding windows, later nicknamed the "aquarium," was born. The all-wheel-drive "vakhtovka" (crew vehicle), designated StZM-3906, was compact, spacious enough to transport a full work crew to remote areas, and enjoyed considerable demand.
Further development of this success in the early 1990s led to the release of a new modification, the StZM-32151-30. Among other improvements, the vehicle's internal communications were radically improved. Whereas previously there had been a blank wall behind the front seats, now the cabin and passenger compartment were connected by a fabric vestibule.
Why couldn't the classic single-volume "Bukhanka" (Loaf of Loaf) be used as the basis from the start? It's simple – the design perfected on the heavier "vakhtovka" (crew-hauled vehicles) worked. In Stavropol, the latter were designed on the basis of existing dump trucks, replacing the body with a passenger module. The same thing happened with UAZs: instead of minibuses, the SOZSA received a chassis with a "Tadpole" (Galovastik) cabin, onto which a crew compartment was mounted.
The StZM-32151-30 was rightfully considered a step up from the previous model. But times changed, and the spartan conditions of the compact crew-hauled vehicles no longer satisfied customers. In 1997, having produced the last batch of vehicles, the Stavropol plant rolled off the assembly line of history. But the memory of these small, stubborn all-terrain vehicles lives on!
