Silkworm (missile) - SY-series

SY-series

The SY-series were developed from the Soviet P-15 Termit. They were used on small missile boats with limited electronics. The Chinese encountered difficulties making the missile compatible with the more complex systems of larger warships. This could have resulted in premature launches or detonations when the electronics were placed on full power. In response, the HY-series was designed for warships and to replace the SY-series.

The SY-series was initially produced concurrently with the HY-series to arm missile boats and to provide an inexpensive alternative for export.
