Organized around the INCOSE Systems Engineering Handbook lifecycle framework, this article traces how reusability requirements propagate — from conceptual trade-space definition through operational sustainment — across propulsion, thermal protection, ground infrastructure, regulatory compliance, and cost architecture. The Space Shuttle's failure to establish refurbishment cost and cycle time as first-class key performance parameters is ...

Inside North Korea's Shadow Workforce

  How Pyongyang's IT Army Infiltrated Hundreds of American Companies An industrial-scale operation deploying thousands of fake remote workers — armed with stolen identities, AI deepfakes, and U.S.-based facilitators — has siphoned hundreds of millions of dollars into Kim Jong Un's weapons programs while stealing sensitive American technology. Federal law enforcement is playing catch-up against a threat that has already penetrated Fortune 500 boardrooms, defense contractors, and even cybersecurity firms themselves. Updated: March 16, 2026 Bottom Line Up Front The Democratic People's Republic of Korea (DPRK) has built a state-directed, large-scale remote-work fraud operation deploying thousands of IT workers who use stolen American identities, AI-generated deepfakes, and a network of U.S.-based accomplices — called "laptop farm" operators — to fraudulently gain employment at American companies. The operation gene...
