“Lekki Samobieżny Przeciwlotniczy Zestaw Rakietowo-Artyleryjski “Stalagmit””

“Light Self-Propelled Anti-Aircraft Missile-Artillery System “Stalagmite””

The LSPZRA Stalagmit originated from the earlier Sopel programme, developed by OBR SM in Tarnów and OBRMZiT in Stalowa Wola. Design work began in March 1993, with a prototype completed by December of the same year. It was built on a modified amphibious Opal II chassis and featured a newly developed turret armed with twin 23 mm autocannons. Although the original Sopel was relatively simple, and used a tachometric sight, plans were made to introduce a more advanced targetting system to increae its effectiveness.

In November 1994, the Sopel programme was combined with the separate Stalagmit project, which had originally explored an anti-aircraft system based on the T-55 chassis. The combined programme, overseen by OBR SM Tarnów, resulted in the Stalagmit/Sopel (another name for the vehicle). Its first version was completed approximately nine months later, retaining the twin 23 mm armament while gaining new Israeli opto electronics

The prototype underwent firing and field trials, demonstrating the system’s capabilities. Further configurations were also considered, including installation on a wheeled MOWAG Piranha III chassis and a variant armed with a singular 35 mm cannon. The system was presented at MSPO 1999 in Kielce, but despite its potential, it never entered serial production. Financial limitations ultimately prevented its adoption by the Polish Army.

The vehicle still exists today, rotting away.
