OVERVIEW: The 107mm Rocket is an unguided, fin- and spin-stabilized artillery rocket designed for short-range direct and indirect fire missions. Iran employs navalized versions of this rocket on small fast-attack craft for use against coastal and light naval targets.

DETAILS: The 107mm rocket, originally developed by China as the Type 63, is a lightweight, solid-fueled artillery rocket. It carries a high-explosive fragmentation warhead with point-detonating fuzing and is stabilized by fins and spin during flight. Designed for massed fire, the rocket is launched from single or multi-tube launchers and is intended for area saturation, infantry support, and light target neutralization. Its compact size and simplicity make it adaptable to both land and naval platforms, especially in low-intensity conflict environments.

Iran has developed and fielded the Haseb-1, a domestically produced version of the 107mm rocket, based on the Chinese Type 63 design. In addition to land-based platforms, Iran has mounted these rockets on small naval craft such as MIG-G and MIL 40 boats to increase firepower in swarm tactics. These naval applications involve integrating 107mm rocket tubes on deck mounts or rotary launchers. The Iranian version maintains the original ballistic profile but has been adapted for stability in maritime environments.

In operational use, the navalized 107mm launchers are mounted on high-speed boats, manually or electrically aimed, and typically fired in salvos during hit-and-run attacks. Rockets are preloaded and launched using visual targeting or basic fire-control systems without radar guidance. This configuration allows Iranian fast-attack craft to threaten coastal facilities, anchored ships, or pursue asymmetric naval engagements in littoral waters.
