COMAC CBJ demonstrator at exhibition — China’s large-cabin business jet adapted from the C909.

Can China’s Home-Grown Business Jet Compete With Gulfstream?

China’s state-owned airframer COMAC has unveiled a business-jet variant of its C909 regional airliner, marketed as the Comac Business Jet (CBJ), and showcased a completed demonstrator at recent exhibitions. The move is part of a broader push by Chinese OEMs to expand into higher-value aerospace segments, including the large-cabin VIP market dominated by Gulfstream, Bombardier and Dassault.

COMAC adapts the CBJ from the C909 (a rebrand of the ARJ21 line) and promotional layouts suggest flexible interiors that could seat up to around 29 passengers in special configurations. Industry analysts, however, caution that the path from a showcased demonstrator to a globally competitive business jet depends on international certification, supply-chain maturity, and an after-sales and service network, areas where Western OEMs currently have a significant lead.

What COMAC showed and why it matters

  • Exhibition reveal: COMAC displayed a finished CBJ demonstrator in Guangzhou and participated in other recent air shows, signalling public intent to enter the business-jet market. AIN and SCMP covered the displays and technical background.
  • Aircraft lineage: The CBJ is derived from the C909 regional jet family (ARJ21 heritage), which has been certificated by China’s CAAC for regional airline use. COMAC’s C909/CBJ strategy leverages an existing airframe and systems to speed development of a VIP variant.

Specs & cabin: big-cabin ambitions 

COMAC promotional material and trade reporting indicate the C909 platform supports a large cabin that can be configured as an executive transport, industry sources report interior layouts ranging from about a dozen up to roughly 20–29 seats depending on VIP configuration. That flexibility could appeal to group transport and state/VIP missions. 

The certification and export hurdle

  • Regulatory gap: None of COMAC’s large commercial jets have obtained EASA or FAA type certification to date; European regulators in 2025 estimated that the C919’s EASA validation could take 3–6 years. Without EASA/FAA validation, COMAC cannot easily sell VIP versions to many Western or global corporate customers. 
  • Why that matters: Business-jet buyers, especially corporate, fractional and VIP customers, expect internationally recognised certification, proven reliability, and a worldwide maintenance and support network. These are areas where Gulfstream and other incumbents offer decades of assurance. 

Market & support: where incumbents lead

  • After-sales footprint: Western biz-jet OEMs operate extensive MRO, spares and interior completion networks and partner with global completion centres. COMAC will need to build similar capabilities or partner internationally to reassure buyers.
  • Product maturity: Gulfstream’s jets benefit from decades of incremental design, performance data and operator feedback. COMAC’s CBJ will require a testing and entry-into-service period to prove reliability and operational economics.

Strategic drivers and likely customers

  • Domestic demand & state sales: COMAC can leverage the Chinese market and state-related VIP demand as a first customer base where CAAC certification suffices. Government, corporate and regional VIP transport within Asia could form an initial market.
  • Niche opportunities: The CBJ’s larger cabin layouts may attract customers seeking group transport, special mission roles or high-capacity VIP flights, niches less well served by narrow-cabin business jets.

Timeline 

Showcases & market testing: COMAC’s exhibition of the demonstrator is an early step. Next milestones to watch are flight testing reports, CAAC certification details for the CBJ variant, and any announcements of completion centres or international certification programmes. 

Takeaway: potential is real, but rivalry is distant 

COMAC’s CBJ demonstrates China’s intent to move up the value chain in aerospace. The firm’s advantage is a large domestic market and state backing, both can accelerate development and initial sales. But matching Gulfstream is not just about an aircraft in a hangar; it requires multi-year certification, worldwide support, demonstrated operational performance, and buyer confidence. For now, the CBJ is a credible entrant in the large-cabin VIP space, not yet a proven rival to established Western business-jet leaders.
