Deep Blue Aerospace
Overview
Larger, five-meter-diameter kerosene-liquid oxygen heavy-lift rocket stepping up from Nebula-1, designed to carry more than 25,000 kg to LEO on a cluster of up-rated Thunder-RS engines with planned first-stage recovery and reuse.
The Thunder-RS first-stage engine completed its first 100-second full-duration static fire around August 21-22, 2026, reaching 1,297.5 kN (~132.3 tonnes) of thrust - the engine's first crossing of the 100-second steady-state qualification threshold. No maiden-flight date has been confirmed as of late August 2026.
