The Chinese Yaogan 29 (Remote Sensing Satellite-29) government remote sensing satellite, likely also used as a military reconnaissance satellite, is likely the first of a successor series to the Yaogan-1 (JB-5) class space-based synthetic aperture radar (SAR) system.

The satellite uses the same orbit as the Yaogan-1 class, but has, according to published illustrations, a different design.

Yaogan 29, was launched in November 2015 on a CZ-4C rocket into a 615 km × 619 km, 97.8° orbit.

A second satellite of this type, Yaogan 33-01, failed to reach orbit on 22 May 2019.

Likely the third satellite of this type, Yaogan 33-01R, reached orbit on 28 December 2020. It is believed to be a replacement for the lost satellite, although a different launch site was used and a higher orbit was obtained.
