Why it matters
Relativity Space is building Terran R, a two-stage reusable rocket it presents as sized for low-Earth-orbit constellations and heavier missions. The product page, read on 21 October 2026, says launches from Launch Complex 16 at Cape Canaveral Space Force Station start in late 2026. It also states more than $3 billion in launch service agreements with government, commercial, and telecommunications customers. The about page describes that total as pre-sold launch contracts across more than a dozen customers. Terran R has not flown.
The about page says that in 2025 the company began a new chapter under former Google CEO Eric Schmidt, and that the team has grown since 2016 to 2,000 people working in California, Mississippi, Florida, Washington, D.C., and Seattle. Headcount and the contract total are company statements on the public site.
Terran R
The product page lists Terran R at 284 feet (86.6 m) tall and 17.7 feet (5.4 m) across, for both the vehicle diameter and the payload fairing. Thirteen Aeon R engines are rated at 269,000 lbf of sea-level thrust each, for 3,497,000 lbf at liftoff. One Aeon V vacuum engine is rated at 323,000 lbf. Both use liquid oxygen and methane in a high-pressure gas-generator cycle. The page says Aeon R went from design to qualification in 14 months.
Quoted performance is 23,500 kg to low Earth orbit and 5,500 kg to geosynchronous transfer orbit with a downrange landing, and 33,500 kg to low Earth orbit if the booster is expended. These are design figures for a rocket that is still in ground test.
Ground test
The July 2026 company update, posted 11 August 2026, said stage-one structural qualification was complete: 420 pressure cycles, 62 proof, stability, and ultimate loading cases, and 4.3 million lbf of axial compression on a pressurized tank. Aeon V had finished acceptance testing, which the update described as wrapping up all engine testing for Flight 1. At NASA Stennis, Stage 2 had been mated to the stand and had completed cryoproof testing and composite-overwrapped pressure vessel proof testing. At Launch Complex 16, the horizontal integration facility was energized, a 270,000-pound crane had completed its first proof-load test, and the transporter-erector upper strongback was on site.
The September 2026 update, posted 12 October 2026, said all 13 Flight 1 Aeon R engines were installed on the thrust structure and gimbal testing was underway, checking that the engines can pivot to steer the vehicle. The liquid-oxygen downcomer was installed in the stage-one tank, with a tank leak check as the next milestone, and Flight 2 and Flight 3 engines were in manufacturing. At NASA Stennis, Stage 2 was on the A2 stand with the Aeon V installed. The team had completed a test readiness review and a wet dress rehearsal with flight-like propellant loads, COPV fills, engine chill, and a simulated first-stage ascent. The update places that campaign ahead of the first hot fire. The east lightning tower was at 530 feet, east launch-table steel was complete, and permanent 480-volt pad power was energized.
On 16 October 2026 Relativity said Stage 2 had successfully completed its first integrated hot fire at Stennis, and that A2 was supporting stage testing again after a Saturn V upper-stage firing on 30 October 1970. The post states success and leaves out burn duration, thrust, engine configuration, and any Stage 1 result. Until a test report states the firing, this remains a company social-media claim.
Launch demand
The about page and the Terran R page both state launch agreements of more than $3 billion. The July update says U.S. Space Force Space Systems Command on-ramped Relativity in July 2026 into National Security Space Launch Phase 3 Lane 1. That passage reports the on-ramp and states no task order or dollar amount. No Terran R launch has flown against the stated agreements.
What to watch
The product page still schedules the first launch from Launch Complex 16 for late 2026. On 12 October, Stage 1 still had the tank leak check ahead of it, and a Stage 1 hot fire is absent from that update and from the 16 October Stage 2 post. Those company pages also do not announce an FAA vehicle operator license for Terran R. The next public markers are a documented Stage 2 firing, a Stage 1 hot fire, a license, and any change to the late-2026 date.
