Hyperbola-3

In Development

Two-stage, partially reusable methane-liquid oxygen rocket with a sea-recoverable first stage - iSpace's Falcon 9-class vehicle aimed at low-cost, high-cadence launch for satellite constellations.

01

Current status

JD-2 / Focus-2 engines and both stages were qualified for flight by April 2026, with a pathfinder delivered to Wenchang. By mid-2026 the first-stage sea-recovery landing system had completed full-profile ground verification (a flight-weight drop-and-shock test), and in June 2026 the Qinglan recovery drone ship completed offshore sea trials with the pathfinder, holding stability in 4 m waves. On August 14, 2026 the 5.2 m payload fairing passed its final static-load test. On September 18, 2026 the first-stage methane tank and second-stage common-bulkhead tank passed ultimate-load static tests to structural failure, which iSpace said shows its 4.2 m tank line can support batch production and supports the maiden flight. A first orbital flight from Wenchang LC-2 with a sea-recovery attempt remains targeted for late 2026 (year-end / Q4); as of September 20, 2026 launch trackers still listed the demo as NET 2026 with a placeholder December 31 date and no slip announcement. Backed by fresh Series E capital whose first tranche closed in August 2026.

Announced next steps from iSpace (Interstellar Glory) that mention Hyperbola-3.

  1. 2026-2027

    Demonstrate first-stage recovery and reuse

    Move beyond reaching orbit to recovering and reflying the Hyperbola-3 first stage at sea - the core of iSpace's low-cost launch strategy - having completed full-profile ground verification of the landing system and June 2026 offshore sea trials of the Qinglan recovery drone ship. The debut mission itself is planned as the first sea-recovery attempt; a successful reflown booster would follow in 2027 if the late-2026 landing works.

  2. 2026-2027

    Bring Chengdu production base online; advance Hyperbola-9

    Put the record 5.037 billion yuan (~$729.6M) Series D++ closed in February 2026, plus the first tranche of a new Series E round (nearly 1 billion yuan, ~$140M, out of a round reported at ~7 billion yuan / ~$980M total) closed in August 2026, to work - completing the 3.3B yuan Chengdu production base (Chengdu reporting in April 2026 still targeted completion by end of 2026, equipment debugging late 2026, and official production in 2027, sized for 20 rockets/year), expanding Hyperbola-3 final assembly and integrated-test capacity, building out Focus-2 methalox engine and sea-recovery infrastructure, raising Hyperbola-1's reliability, and starting early R&D on the heavy-lift Hyperbola-9 and its 300-tonne-class Focus-3 engine.

  3. Late 2026

    Hyperbola-3 first orbital flight

    TargetLate 2026 (year-end / Q4)

    Fly the reusable Hyperbola-3 for the first time from Commercial LC-2 at Wenchang, having qualified its engines and stages, completed Qinglan drone-ship recovery sea trials in June 2026, passed the payload fairing's final static-load test on August 14, 2026, and completed ultimate-load static tests of the first-stage methane tank and second-stage common-bulkhead tank as of September 18, 2026, attempting a sea-based first-stage recovery on the debut - still targeted for late 2026 (year-end / Q4). Company officials have not issued a locked December calendar date; public launch lists as of September 20, 2026 still show NET 2026 / a placeholder December 31 date, with no slip announced.

  4. H2 2027

    List on the Shanghai STAR Market

    Progress toward an IPO on Shanghai's STAR Market, reportedly targeted for the second half of 2027 once Hyperbola-3 has completed its debut orbital flight and sea-recovery attempt - a milestone China's fifth listing standard requires for a reusable medium/large launch vehicle.

  1. iSpace closes first tranche of Series E, nearly $140M raised

    Chinese rocket maker iSpace (Interstellar Glory) said August 5 it closed the first tranche of a new Series E round worth nearly 1 billion yuan (about $140M), led by bank-affiliated asset-management institutions, with the broader round still underway. Proceeds are earmarked for Hyperbola-3 reusable-rocket production, Focus-2 methalox engine capacity, and launch and sea-recovery infrastructure, building on the record 5.037 billion yuan (about $729.6M) Series D++ iSpace closed in February 2026.
