OVERVIEW: The BR-128M-74 is an unguided, short-range, high-explosive (HE) rocket designed for use by the G-4 Super Galeb light attack and trainer aircraft for ground-attack missions. It delivers fragmentation effects against personnel, soft targets, and light fortifications.

DETAILS: The BR-128M-74 is a 128mm air-to-ground rocket developed in Yugoslavia and adapted for fixed-wing aircraft including the G-4 Super Galeb. "BR" stands for Borbena Raketa (Combat Rocket), "128" for caliber, "M" for model, and "74" for its adoption year 1974. The rocket is spin-stabilized and fired from underwing-mounted rocket pods such as the L-128/4 or L-128/16, depending on aircraft loadout. It carries a high-explosive fragmentation warhead, designed for anti-personnel and anti-material roles. Maximum effective range is around 2 to 3 km, depending on launch altitude and speed.

This variant is specifically configured for aircraft use, with electrical fuzing interfaces and launch pod compatibility for airborne deployment. It differs from the artillery-launched BR-128 versions through enhanced aerodynamic tolerances and fuse safety modifications suited for high-speed aerial delivery. Rockets are carried in disposable or reusable pods, allowing selective salvos or ripple fire.

The BR-128M-74 is deployed by loading rocket pods on the G-4’s underwing pylons. The pilot selects firing mode through the aircraft’s weapons panel, and rockets are launched in single or burst mode during low-level attack runs. It is intended for close air support, battlefield interdiction, or area denial.
