Who We Are

Roysdon Defense Technologies (RDT) delivers advanced engineering solutions for the nation's most demanding defense and intelligence missions.

Founded by a former Deputy Director of National Intelligence and NSA Chief Data Scientist, RDT brings more than 25 years of experience across the Intelligence Community, Department of Defense, and aerospace industry. Our leadership has directed national-scale science and technology initiatives and developed mission-critical systems spanning artificial intelligence, cybersecurity, autonomous aircraft, advanced navigation, and secure infrastructure.

We have served the customer, led the programs, designed the systems, built the hardware, written the software, and delivered operational capabilities. We understand the mission because we have lived it.

Why We're Different

We combine the depth of a national laboratory, the execution speed of a small engineering team, and the operational perspective of the customer.

Our expertise spans the complete engineering lifecycle—from advanced mathematics, modeling, and simulation to hardware design, software development, manufacturing, integration, and operational testing.

Our leadership has helped deliver complex aerospace and national-security systems on accelerated schedules, including aircraft programs progressing from concept to flight in as little as 6–12 months.

Our advantage is engineering velocity: eliminating organizational boundaries, integrating disciplines from day one, and translating complex technical challenges into mission-ready capabilities.

Built by engineers. Informed by operators. Driven by the mission.

Leadership

Dr. Paul F. Roysdon

CEO | Founder | Former Deputy Director of National Intelligence

Paul Roysdon brings more than 25 years of leadership and hands-on engineering experience across the U.S. Intelligence Community, Department of Defense, and aerospace industry.

His career spans positions as Deputy Director of National Intelligence (ODNI), Chief Data Scientist (NSA), and Chief AI Scientist & Vice President (Leidos), he has led nation-wide science and technology portfolios and mission-critical technology initiatives at the highest levels of national security. He is also the recipient of multiple national awards, including NSA Director’s Award, NSA Inventor Award, ODNI Director’s Award and the Leidos Innovation and CTO Awards.

Unlike traditional executives, Roysdon is also a multidisciplinary engineer and applied mathematician with extensive hands-on experience designing, developing, and flight-testing advanced aerospace systems, including the BQM-167, BQM-177, MQM-178, and GQM-173. His expertise spans AI, cybersecurity, quantum physics, aerodynamics, advanced composites, autonomous guidance and flight control, precision navigation, embedded systems, 6DOF simulation, and manufacturing. Roysdon has also authored several peer-reviewed textbooks and scientific publications.

His defining advantage is the rare combination of national-level strategic leadership and the ability to personally engineer the technologies required to accomplish the mission.
