PENTAGON BUNKERS OÜ – Modular Defence Infrastructure

Pentagon Bunkers OÜ is an Estonian high-tech manufacturer developing the next generation of modular concrete protection and shelter systems for military and strategic use. Our innovation is based on a unique pentagon-shaped modular architecture that ensures outstanding structural integrity, tactical flexibility, and both horizontal and vertical scalability.

Our bunker systems are designed in full compliance with NATO standards,
Eurocodes, and EU structural regulations, using only certified and controlled materials such as C35/45-2-grade concrete – specifically formulated for protective infrastructure and blast resistance.

The development process is carried out in cooperation with defence sector experts, construction engineers, and architects, ensuring maximum operational usability, transportability, and deployment efficiency in the field.

These are not static buildings – they are mission-adaptable infrastructure units, capable of serving as troop shelters, command centers, storage modules, or fortified operational bases. With their modular expandability in all directions, Pentagon Bunkers offer a flexible, future-proof platform for the evolving demands of modern defence.
