S-8 (rocket)

The S-8 is a rocket weapon developed by the Soviet Air Force for use by military aircraft. It remains in service with the Russian Air Force and various export customers.

Developed in the 1970s, the S-8 is an 80 mm (3.1 in) rocket used by fighter bombers and helicopters. The system entered service in 1984 and is produced in a variety of subtypes with different warheads, including HEAT anti-armor, high-explosive fragmentation, smoke, and incendiary, as well as the specialized S-8BM runway-destroying munition and the S-8DM fuel-air explosive variants. Each rocket is between 1.5 meters (4 ft 11 in) and 1.7 meters (5 ft 7 in) long and weighs between 11.3 kg (25 lb) and 15.2 kg (33.5 lb), depending on warhead and fuse. Range is 2 to 4 kilometers (1.3 to 2.6 mi).

The S-8 is generally carried in the B series of rocket pods, carrying either seven or 20 rockets.

In 2018, the Russian Aerospace Forces took delivery and completed state tests of several batches of the S-8OFP Broneboishchik, successor to the S-8. While both rockets are unguided, the S-8OFP has greater range, a heavier warhead, and a digital fuse. The rocket is intended for armament of Su-25 type aircraft and Mi-8 helicopters, depending on the settings of the fuse, is able to penetrate obstacles facing the set targets, it can also explode in front of the obstacle and behind the obstacle, without destroying and continuing the flight.
