We specialize in underground survival shelters, fortified bunkers, and self-sustaining defense systems. Our work includes steel and concrete bunker construction, proprietary air filtration, energy and water systems, communication networks, and autonomous drone defense — all engineered and installed by our in-house team.
We serve both private and institutional clients. Our shelters are custom-engineered for residential, corporate, and governmental use, offering scalable protection for families, estates, and critical infrastructure.
Yes. Confidentiality is guaranteed. Every consultation, design, and build is handled under strict non-disclosure and security protocols. We never share client names, project locations, or system specifications without written consent.

Each shelter “Level” represents a higher degree of protection, autonomy, and capability:
Construction timelines vary by size and complexity.
Our engineering team will provide a project timeline during your initial consultation.
Yes. Most installations occur directly beneath or adjacent to existing properties. Our engineers perform a full site and soil analysis to determine feasibility, access, and optimal layout before construction begins.
Capitol Defense Systems uses a hybrid steel-and-concrete design for maximum strength and longevity. Structural steel frames are encased in high-density, reinforced concrete to ensure blast resistance, stability, and long-term corrosion protection.
Absolutely. Many of our designs are modular, allowing you to add new rooms, corridors, or system upgrades — including Level 2 and Level 3 expansions — as your needs evolve.

We install our proprietary CleanAir-X™ Filtration System, available in three tiers:
Our Aegis™ Autonomous Drone Defense Network operates using proprietary non-GPS navigation — powered by internal spatial mapping, infrared scanning, and encrypted signal triangulation. This allows our drones to maintain full operational capability even in GPS-denied or jammed environments, providing uninterrupted perimeter defense.
We design all shelters for complete energy independence using our PowerGrid-X™ Systems, which can include:
Yes. Every shelter integrates into our CommandView™ Control Console, a secure touchscreen interface that manages air, power, lighting, communications, surveillance, and drone systems — all from a single encrypted network.

Every Capitol Defense Systems structure is custom-engineered for your specific site, protection goals, and budget. While our Level 1–3 models define system tiers, every project is tailored to the client’s requirements.
Costs vary widely based on size, systems, and finishes.
A design consultation is required for precise cost evaluation and site-specific planning.
Yes. Our Level 3 Elite Shelters often include custom-designed living spaces, climate control, luxury materials, entertainment systems, and architectural finishes — all engineered for comfort without compromising security.
Please reach us if you cannot find an answer to your question.
Yes. Our team manages all permitting, structural engineering, and compliance documentation required for your project. We work closely with local authorities when necessary, maintaining full confidentiality.
Absolutely. We provide scheduled maintenance and system inspections to ensure all air, power, and mechanical systems remain operational and ready at all times.
Yes. We offer upgrades for air filtration, energy systems, and interior enhancements — even on non-Capitol Defense Systems structures. Our engineers can evaluate your current setup and modernize it to meet current standards.

CleanAir-X™ is our proprietary multi-stage air filtration and overpressure system, designed exclusively for sealed underground environments. It protects occupants from radiological, chemical, and biological agents, while maintaining breathable air under all external conditions.
Unlike off-the-shelf filters, CleanAir-X™ is engineered for redundancy and adaptability:
This system exceeds typical CBRN standards and is built to military-grade containment specifications.
Maintenance is minimal. Filters are rated for 5,000–10,000 operational hours depending on environment. Capitol Defense Systems provides annual inspection, filter replacement, and pressure calibration through our service program.
Yes. It includes manual override and backup airflow systems, allowing full air cycling during grid or generator failure. For Level 3 installations, CleanAir-X™ integrates with PowerGrid-X™ battery and hybrid power, maintaining uninterrupted filtration.
Absolutely. Each CleanAir-X™ unit supports modular ducting and can be linked to multiple sealed zones with independent control, ensuring pressure integrity and contamination isolation across the structure.

Aegis™ is our proprietary, GPS-independent aerial and ground defense system. It creates an automated security perimeter using autonomous drones equipped with optical, infrared, and LiDAR mapping to detect, track, and respond to intrusions.
Our drones use internal spatial mapping, signal triangulation, and inertial navigation algorithms instead of satellite-based positioning. This allows for full situational awareness even in GPS-denied or jammed environments — a crucial advantage during defense operations.
They can operate in three modes:
All communications use encrypted, mesh-network protocols for security and reliability.
Each drone docks in a hardened charging bay integrated into your structure or perimeter fence line. Charging bays connect directly to PowerGrid-X™, allowing for solar, generator, or grid power recharging.
Yes. Aegis™ supports network integration with camera feeds, motion sensors, and security alerts via our proprietary CommandView™ system. Clients can review live or archived footage securely from any authorized console.
Please reach us if you cannot find an answer to your question.
PowerGrid-X™ is a self-contained, redundant energy ecosystem designed for continuous operation during off-grid or emergency scenarios. It intelligently balances solar, generator, and stored power sources to ensure uptime.
The system uses adaptive energy allocation, automatically prioritizing battery reserves and critical life-support systems. For extended outages, optional hydrogen or geothermal modules can supplement energy production.
Our default configuration uses industrial-grade lithium-iron phosphate (LiFePO₄) batteries for superior thermal stability and longevity (up to 15 years). Alternative chemistries are available for specialized or cold-storage applications.
Yes. PowerGrid-X™ is designed for 100% load redundancy, supporting simultaneous operation of CleanAir-X™, Aegis™, CommandView™, water pumps, and HVAC systems without overload risk. Intelligent throttling ensures constant efficiency.
Yes. Through the CommandView™ interface, clients can view real-time power levels, consumption trends, and battery diagnostics. For security, remote access uses multi-factor authentication and encrypted transmission.
Please reach us if you cannot find an answer to your question.
CommandView™ is the central nervous system of your shelter — a secure control interface that manages air, power, lighting, communication, and defense subsystems through one encrypted network.
For security, external access is restricted to designated, encrypted devices authorized by Capitol Defense Systems. Clients may choose local-only or remote-enabled configurations depending on security requirements.
Every system includes a redundant manual control interface, ensuring all core life-support and defense functions can be operated offline. Redundant cabling and physical bypass switches are standard in all Level 2 and Level 3 builds.
Yes. CommandView™ supports modular integration for third-party surveillance, environmental monitoring, or communications systems. Our engineers will ensure secure API-level compatibility without exposing core systems.
Please reach us if you cannot find an answer to your question.
Yes. All proprietary systems — CleanAir-X™, Aegis™, PowerGrid-X™, and CommandView™ — come with a 10-year limited performance warranty, with options for extended service and 24/7 monitoring contracts.
We recommend biannual diagnostic checks for all automated systems and quarterly testing for power and air systems under emergency conditions. Capitol Defense Systems offers maintenance programs for all system types.
Yes. Our engineers can retrofit CleanAir-X™, PowerGrid-X™, or CommandView™ into most existing structures — even non-Capitol builds. Site evaluation is required prior to installation.
