“Neptune’s design is based on the Soviet Kh-35 anti-ship missile, with substantially improved range and electronics.[1] The system is designed to defeat surface warships and transport vessels with a displacement of up to 5,000 tons, either in convoys or moving individually.

“Neptune coastal defence system comprises a USPU-360 truck-based mobile launcher, four missiles, a TZM-360 transport/reload vehicle, a RCP-360 command and control vehicle, and a special cargo vehicle. The system is designed to operate up to 25 km inland of the coastline.[2]
“A Neptune missile including rocket motor is 5,050 mm in length, with a cross-shaped hard wing. Neptune missiles are designed to be housed in transport and launch containers (TLC) with dimensions 5,300 × 600 × 600 mm. The system has a maximum range of about 300 km.[10][11] A single missile weighs 870 kg, of which 150 kg is the warhead.”
