Terran R
Overview
A two-stage reusable medium-to-heavy-lift rocket designed for constellation deployment, large satellite missions, and higher-cadence commercial and government launch operations.
In integrated vehicle build and testing as of mid-August 2026: the stage-one structural qualification campaign is complete, the flight-one second stage completed cryoproof and COPV manifold proof testing at NASA Stennis's A-2 test stand, and all Flight 1 engines (13 Aeon R first-stage engines plus the Aeon V second-stage engine) have completed acceptance testing. The first Aeon R engines are now being installed onto the first-stage thrust structure at Long Beach, and the LC-16 Horizontal Integration Facility at Cape Canaveral is structurally complete with pad infrastructure (water tower, flame diverter, lightning protection towers, transporter-erector) continuing to come online. First launch is targeted for the second half of 2026 (some observers expect a slip into 2027).
