The Lagerbunker MB-2 at Raketentechnische Basis 2 was a military storage bunker located in Brandenburg, Germany. Built during the Cold War era, it formed part of a larger rocket technical base complex. The structure was designed for the secure storage of military equipment and supplies related to rocket technology operations.
As a hardened facility, it featured reinforced concrete construction typical of Cold War-era military bunkers. The site reflects Germany's strategic military infrastructure development during the period of division and the presence of Soviet-aligned forces in East Germany.
