PB 500 (500mm) modular bunker network is being developed with the finnish engineers and arhitects.
ADVANCED MODULAR BUNKER SYSTEM
Why Pentagon Shape?
Tactical Connectivity
Each module connects in 7 directions, enabling flexible layouts, fast network expansion, and built-in redundancy for military and civil defense scenarios.
Geometric Efficieny
The pentagonal shape optimizes internal volume while allowing strategic distribution of support systems (ventilation, cabling, escape paths) without blocking movement.
Structual Integrity
Pentagon geometry disperses shockwaves and increases wall resistance. Sloped interior walls and multi-angle joins provide unmatched structural durability in hostile environments.
Modular Scalability
Stackable vertically and expandable horizontally, Pentagon Bunkers adapt to terrain, mission profiles, and long-term infrastructure needs – from command centers to evacuation shelters.
