capsule that parachuted to ocean landing.  First stage returned 
for hover and "soft" landing on ocean surface after engine restart.
Used short first stage and no second stage.   

[CZ-10B Y1] 07/10/26 0415.  Inaugural CZ-10B two-stage launch with 
CH4/LOX YF-219 powered second stage.  First Stage (X1.1) reentered 
and was cable-captured by offshore platform.

            CZ-10 LAUNCH VEHICLE FAMILY
                  by Ed Kyle

The CZ-10 family, developed by CALT, use 5 m diameter stages.  
CZ-10B uses a LOX/kerosene first stage and CH4/LOX second stage.  
CZ-10A, designed to launch crewed missions, uses the same first 
stage and a yet-to-fly second stage.  Both types use first 
stages designed to be recovered by a cable capture apparatus 
on an offshore platform.     

The CZ-10A/B first stage uses seven upgraded YF-100K type oxygen 
rich staged combustion first stage engines.  They are designated 
YF-100N/P/L depending on whether they are restartable for entry 
and landing.  They develop 892.251 tonnes of liftoff thrust.    

A single YF-219 engine powers the CZ-10B second stage.  This 
140 tonne thrust class engine burns CH4 and LOX.  

The first CZ-10A-based test flight on February 11, 2026 was a 
suborbital test of both a new orbital capsule abort system and of 
the first stage reentry and landing system.  For this test the 
first stage hovered just outboard of the cable capture platform 
before dropping into the sea.  The first stage was a short version 
of the ultimately planned CZ-10A/B booster.

CALT has announed that CZ-10A will use only brand-new first stage 
for crewed missions, while CZ-10B will use the recovered CZ-10A 
first stages.  

A planned CZ-10C will use an entirely new methalox first stage 
topped by the CZ-10B second stage.  This rocket will be much 
taller and more capable.
