The PHZ-11 shares similar armaments with the PHL-11, but with a tracked chassis.[2]
Design
Each PHL-11 is equipped with 40 122 mm rockets mounted on a swivel mount with 2 pods of 20 rockets each.[3] The SR-5 export version is fitted with 2 modular rocket pods able to carry either 20 122 mm or 6 220 mm rockets in each pod.
Each SR-4 launcher vehicle is usually paired with a reloading vehicle based on a Shaanxi 8x8 military truck fitted with a crane. It carries pods of rocket reloads and reloads the launcher vehicles. As such, reloading time has been cut from 10 minutes to 5 minutes.[4]
The vehicle is equipped with a fire control computer and CBRN protection for the crew.[3][4]
The PHL-11 can also fire 122mm DTI-2 rockets manufactured by Thailand's Defense Technology Institute.[3]
Chassis
The vehicle used is a 6x6 Shaanxi SX2190KA. The vehicle is equipped with a 206KW Weichai WD615-77A straight-six diesel engine paired with 9 speed manual transmission. The vehicle can reach a speed of 80 km/h and has off-road capability. Another variant features armor plates on windows, including fold up plates on side windows and blind curtain armor on the frontal windscreen.[1]
Based on tracked vehicle chassis similar to PLZ-05 and PGZ-09.[1]
SR-4
Export version of PHL-11 using 6x6 Shaanxi SX2190KA truck chassis
SR-5
Export version with 2 modular rocket pods using 6x6 Taian TA5310 truck chassis.[4] Each pod is able to carry either 20 x 122 mm, 6 x 220 mm rockets, 1 x 610 mm King Dragon 300 ballistic missile, 1 x C-705 anti-ship missile, or various loitering munitions and drones.[5]
The SR-5 is a fully computerized and digitized system. It reduces operational costs by allowing multiple types of ammunition to be adapted to a single chassis using the same fire control and support systems.[6]
SR-7
The SR-7 is a lightweight, scaled-down variant, with either one pod of twenty 122 mm rockets or six 220 mm rockets.[7] The maximum range is 50 km for the 122 mm rocket and 70 km for the 220 mm rocket. First unveiled in IDEX 2017 mounted on a 6x6 assault vehicle (presumably Dongfeng Mengshi).[8]
Truck chassis based on the FAW MV3 series of tactical trucks, specifically the 4x4 CTM-133 variant, similar to the ones used on PCL-161 lightweight howitzer.[10] It uses the same scaled down one pod of twenty 122 mm rockets as the SR-7. It has been observed in PLA service.[11][12]
