3db Engineering

We help spacecraft, launch vehicle, and defense teams de-risk flight-critical systems and hit milestones without surprises. With over two decades in launch vehicles, rotorcraft, and spacecraft, we bring certification-driven clarity to autonomous systems, defense retrofits, and orbital platforms. UAS & Autonomous Systems – From loitering munitions to ISR drones, we engineer survivable, test-ready structures that meet mass, vibration, and thermal targets from day one. Defense Retrofits – We adapt and certify complex payloads, ISR pods, and modular upgrades, delivering DER-ready analysis for fielded platforms under pressure. Flight & Orbital Systems – From NASA payloads to defense missions, we provide cert-aligned analysis and documentation from hangar to payload fairing. Flight-qualified. Cert-aligned. Built for deployment. You can’t out-hustle physics. We’ll help you get to mission success—without slowing your team down.
