The Russian State Defense company ROSTEC has announced at the end of December 2021, that the Sprut-SDM1, a modernized version of the Sprut-SD amphibious light tank is ready for serial production.
In 2021, the armament of the Sprut-SDM1 lightweight amphibious tank was tested in the Black Sea during the second stage of the armored vehicle state trials. The vehicle has demonstrated its ability to fire with its 125mm cannon in calm sea conditions as well as in a moderate sea.
The Sprut-SDM1 has already conducted sea trials showing its ability to navigate on the sea and its capacity to be transported by large amphibious assault ships and also by military transport aircraft as the Il-76. The vehicle has also traveled more than 8,000 km and it has been tested on all types of terrain and in off-road conditions.
The armor of the Sprut-SDM1 was also tested and showed a high level of protection against ballistic and mines threats.
The Sprut-SDM1 has been developed to be used by the Russian airborne troops, but today many countries all over the world have requested the design of a new light tank weighing less than 30 tones.
