Pallas-2

Name: Pallas-2
Brand: Galactic Energy

In Development

Overview

Larger heavy-lift successor to Pallas-1 in single-stick or triple-core (CBC) configurations, powered by an upgraded liquid oxygen-kerosene CQ-90 engine and sized for constellation-scale payloads.

The first-stage CQ-90 engine, an upgrade of Pallas-1's CQ-50 with bidirectional swing and wide-range variable thrust, completed a full-system hot-fire test on January 20, 2026 with over 96% combustion efficiency. As of early August 2026, Galactic Energy still expected to complete Pallas-2 assembly and testing this year, targeting a maiden flight before the end of 2026; no flight has occurred as of this update.
