The MHSZ has acquired the air defense control armament position BL-64 ZG Bloodhound in the municipality of Menzingen. The facility can be visited via guided tours. The BL-64 ZG Bloodhound is the last of six air defense control armament positions of the British type Bloodhound Mark II, which had been spread across the Swiss Plateau and the Jura Mountains, that is still in good condition. The Bloodhounds had been built for the protection of the Swiss airspace, together with Mirage III combat aircraft and the FLORIDA Airspace monitoring and management system. From the 1960s until the end of the millennium, these three systems had been in service. They have since been replaced by F/A-18 Hornet combat aircraft and the new radar system FLORAKO. The Bloodhounds have not received a successor.
