61

Neutron is coming to life 62

First neutron tanks Hardest part complete Tooling and moulds are the complex, time-consuming part requiring extensive design work and refinement. With these now done, the first hardware has been delivered with more in production at pace. 63

We’re building it We’re experts at 3D-printing rocket engines and we know how to scale. Full scale parts come through our production lines using in-house 3D-printing machines. We own some of the largest 3D-printers in the world. 64

A Design led by market demand P A Y L O A D : 15T (Expendable), 13T (Reusable), 8T (Return to Pad). H E I G H T : 42.8 m / 140.4 ft. F A I R I N G D I A M E T E R : 5 m / 16.4 ft.

Advanced fairing design A slightly less hungry hippo. Captive Fairing: Fairing remains attached to the first stage, opening to deploy the second stage and payload within. Enables rapid re-launch: Eliminates the high cost of expending or capturing and reusing fairings. Iterated Design: From four fairing panels to two. Reduces the amount of angle the fairing must open and enables more robust fairing panels. 66

First stage Major design complete Built for rapid reusability. Tapered profile: First stage has a tapered profile and aerodynamic control surfaces, including canards and landing legs that act as rear-lifting surfaces. Optimized ballistic coefficient: Allows first stage to glide back to Earth for landing, reducing aerothermal load experienced by modern re-entry boosters. 42.8 7 5 9 meter meters meter Archimedes fairing tall diameter engines 67

Not a capsule announcement But we’re looking into it. 68

Not a capsule announcement But we’re looking into it. 69

Second stage major design complete High performance: Designed to maximize mass-to- orbit capability, orbital insertion accuracy, and performance for complex payload deployments. Suspended second stage: Provides easily accessible and condensed mounting location for avionics hardware, aerodynamic control devices, and fluids lines. Also minimizes the requirement for the second stage to withstand the external launch environment. 11.5 1 15 meters Archimedes tonne payload tall engine capacity 70

Rocket Building robots Automated Fiber Placement: Optimized for performance, speed and cost. Advanced composite manufacturing technique: Used to fabricate complex, lightweight vehicle structures with superior strength qualities. Outperforms metallics on structural performance and manufacturing cost: Complete tanks manufactured in days with minimal human labor and less material and waste than metallics. Proven technology: Applying reliable tech used by thousands of aircraft to space. American-made: Built at the launch site in Virginia. 71

The Archimedes Engine Simplicity where it matters. Open Cycle Rocket Engine Oxidizer Rich Closed Cycle Provides higher specific impulse than gas generator, open expander, or tap-off cycles, without the thrust limits or added Oxidizer Fuel Oxidizer Fuel complexity. Tank Tank Tank Tank Gas generator cycles are limited in capability and not suited to the deep throttling required for multiple re-lights in orbit, and for landing the first stage. ORSC engines operate at relatively low temperatures and pressures, eliminating the stress and thermal strain Preburner experienced by gas generator engines. This improves engine [Oxidizer Rich] Main Main life and reusability, while leaving headroom to increase Gas Combustion Combustion performance. Generator Liquid Oxygen and Methane: Provides higher specific impulse than RP-1 kerosene for improved stage performance without the dramatic stage size increase required for low density liquid hydrogen. 73
