 The general designer of C-101 is Liang Shoupan, who is also the general designer of another Chinese supersonic AShM C-101.The C-301 only saw very limited service in the People's Liberation Army Navy as a coastal defense missile, and a stopgap measure in a limited scale production as more capable missiles becoming more widely available.C-301 is also used as a stopgap measure to replace the obsolete C-601 anti-ship missile, the air-launched version of the Silkworm missile carried on the Xi'an H-6 bomber (with one missile under each wing, like the C-601), until more potent supersonic anti-ship missiles become widely available.
