On November 5 at the UP.Summit conference (followed up by Ars Technica and other media on November 6), Blue Origin CEO Dave Limp unveiled Northstar, a new engine for the first stage of the New Glenn rocket. It follows the liquid oxygen/LNG oxygen-rich staged combustion and single-shaft turbopump architecture, and went from project approval to ignition testing in only 11 months. Key metrics: thrust of 715,000 pounds-force (versus 640,000 for BE-4), 30% lower mass, 50% fewer parts, manufacturing cost of about one-quarter of BE-4, and assembly of a single unit in under one day. More than 65% of components are produced through the company's in-house large-scale additive manufacturing, with part count halved by consolidating components through printing. The "printability rate" of commercial space engines has reached another level. The value of metal additive manufacturing is spreading from core components such as thrust chambers and injectors to full-engine structures at scale, and the logic for powder consumption and metal printing equipment demand in large engines is expanding in tandem, creating sustained pull for titanium alloy, superalloy, and copper alloy powders. Value for buyers: Volume production of Northstar will amplify orders for aerospace-grade titanium alloy and superalloy powders and large metal AM equipment. Watch Blue Origin's supplier system and spillover demand for printing services for similar engines.
