The article distinguishes the national LGC class from one preserved focal facility. It supports 64 LGCs in STRIL 50, a 150 m² / 1,615 ft² type design, and one preserved buried concrete bunker of just over 200 m² / 2,153 ft² for ten operators plus a commander, with automatic diesel backup and protection against smaller bombs and gas. It does not give shell thickness, excavation, entry/escape geometry, or cost.
