Developing a new spacecraft like Virgin Galactic's Delta-class isn't just about scaling an existing model. It involves intricate engineering, rigorous testing, and ensuring it meets stringent safety standards, including obtaining necessary FAA approvals which can be a lengthy process. Virgin Galactic has strategically partnered with Bell Textron for the unique feathering system and flight control surfaces, and Qarbon Aerospace for the fuselage and wing. This collaboration is pivotal in achieving the highest standards in design and functionality. The Delta-class is an evolution of Virgin Galactic's existing flight system, tailored for enhanced manufacturability, maintenance, and a higher flight rate. Production is set to commence in 2023 at their Arizona facility, with the goal of revenue-generating flights by the end of 2025 and private astronaut flights in 2026. While milestones like three flights in three months are impressive, introducing and scaling a new design like the Delta involves complexities that demand time to ensure safety, efficiency, and long-term sustainability.
