Yaogan 9, 16, 17, 20, 25 (JB-8 1, 2, 3, 4, 5)

Yaogan 9 (?) [CAST]

The Chinese Yaogan 9 (Remote Sensing Satellite-9) series consists of remote sensing satellites triplets launched by a CZ-4C rocket from China's Jiuquan space center.

These satellites are likely military ocean surveillance satellites similar to the US Parcae (NOSS) series.

The first triplet was launched on 5 March 2010. A second triplet, called Yaogan 16, was launched on 25 November 2011 and a third one, Yaogan 17 followed on 1 September 2013. The fourth triplet launched on 9 August 2014, Yaogan 20, was likely a replacement for Yaogan 9.

These triplets are likely the Chinese equivalents to the US ocean surveillance NOSS satellites.
