Overview

Relativity Space is building Terran R, a reusable medium-to-heavy-lift rocket aimed at commercial, government, and telecommunications missions. After flying Terran 1 as a pathfinder in 2023, the company shifted fully to Terran R and now uses a hybrid manufacturing approach that combines additive manufacturing for fast iteration with more conventional structures for scale and cost. Relativity is focused on engine qualification, integrated vehicle production, and launch-site readiness ahead of a planned late-2026 debut from Cape Canaveral.

Terran 1

Terran 1

Retired

Relativity's pathfinder vehicle, a two-stage small-lift rocket used to validate the company's propulsion, software, and additive-manufacturing approach before the program was retired.

Launched in March 2023 as a pathfinder vehicle and retired after its maiden flight so the company could focus engineering and production resources on Terran R.

What's Next

Terran R first launch

Complete integrated vehicle testing and launch Terran R from LC-16 at Cape Canaveral, proving the vehicle in the medium-to-heavy market and beginning execution against a large launch backlog.

Late 2026

Complete Aeon V and vehicle test campaigns

Finish Aeon V development and qualification work, continue Aeon R acceptance testing, and progress hardware-in-the-loop and stage-test infrastructure needed to clear Terran R for flight.

2026

Bring LC-16 fully online for Terran R

Finish outfitting the horizontal integration facility, launch mount, transporter-erector, water systems, and supporting pad infrastructure so Cape Canaveral operations are ready for first flight.

Timeline

2026Flight hardware and LC-16 buildout advance

By January 2026, Relativity is integrating first- and second-stage hardware, continuing Aeon engine test campaigns, and advancing major launch equipment at LC-16 ahead of first flight.

2025Vehicle-level CDR completed

Relativity completes Terran R's vehicle-level critical design review and begins building first-flight hardware across stages, engines, avionics, and software.

2023Terran 1 reaches space

Terran 1 becomes the first 3D-printed rocket to reach space and serves as the company's pathfinder vehicle before retirement.

2023Terran R architecture updated

Relativity reshapes Terran R around the medium-to-heavy launch market, prioritizing a reusable architecture sized for constellation, commercial, and government missions.

2019Series C funding ($140M)

Relativity closes a $140M Series C round led by Bond and Tribe Capital as it scales Terran 1 development and expands launch infrastructure.

2015Founded

Tim Ellis and Jordan Noone found Relativity Space with the vision of 3D-printing entire rockets.
