The PHL-03 is a truck-mounted self-propelled 12-tube 300 mm long-range multiple rocket launcher of the People's Republic of China.

The main role for this multiple rocket launcher is to engage strategic targets such as large concentrations of troops, airfields, command centres, air defense batteries and support facilities.

The PHL-03 has the same configuration as the original Soviet counterpart with 12 launch tubes for 300 mm artillery rockets, along with a computerised fire-control system (FCS) incorporating GPS/GLONASS/BeiDou.

The PHL-03 uses the 300 mm rockets of the BRE family, namely the BRC4, BRE2 and the guided Fire Dragon 140A which have a range of 130 km (81 mi).

A full salvo of this system could potentially cover an area of up to 67 hectares (170 acres).
