Lead satellite of the Yaogan-17 triplet, launched August 2013 as the third generation of China's naval ELINT surveillance formation. Yaogan-17 joined Yaogan-9 and Yaogan-16 in orbit simultaneously, meaning that by 2013 China operated three complete ELINT triplets — nine satellites total — providing substantially more frequent revisit over Pacific naval operating areas than any single triplet alone.
