Description: The Hermes is a modular, supersonic, bi-caliber, multi-purpose guided missile designed by Tula-based KBP for use by airborne, ground-based and sea-based platforms. The Hermes missile system consists of an expendable booster stage and the primary missile system, also known as sustainer, carrying a powerful high explosive (HE) fragmentation warhead. The spectrum of targets that can be engaged at day/night using the Hermes weapon system includes: armored vehicles, facilities, fortifications and low-speed air targets such as helicopters. The Hermes is sealed inside tube/canister which acts as the missile launcher.
The Hermes-A is a long-range anti-armor/anti-low-speed aircraft missile designed for both rotary- and fixed-wing aircraft such as Ka-52 and Su-39 respectively. The missile is guided through the target area by the inertial navigation system (INS). Terminal guidance is provided by a semi-active laser seeker with the optronic system providing the target designation typically mounted on the aircraft. The Hermes-A has a maximum firing range of between 15 to 20 kilometers flying at an average speed of 500 mps. The missile's diameters are 170mm (booster) and 130mm (sustainer). The sustainer is carrying at least a 28 kg HE fragmentation warhead which can defeat existing and future main battle tanks. Two Hermes-A missiles can be fired against two different targets simultaneously. The missile also features improved resistance against countermeasures compared to existing anti-tank missiles.
Optronics could mean optoelectronics.. if thats the case.. could be Sensors Optical devices integrated in the missile to compare target with an image .or it could work scanning electric signals.
