The Hydra 70 is an American unguided air-to-ground missile from the Cold War and modern times. The length of the rocket - without the head - is 106 cm, with a diameter of 70 millimeters. The take-off weight (without the warhead) is 6.2 kilograms, and its effective range is approx. 8,000 meters. The unit cost of a single rocket is approximately $ 2,800. The Hydra 70 rocket entered service in the early 1950s and remains in service today. The Hydra 70 was developed to replace the FFAR Mk.4 / Mk.40 unguided missile in the line. Compared to its predecessor, it has primarily a changed drive (Mk. 66 solid fuel engine) with greater thrust, which has a positive effect on the range of the projectile and its initial speed. The rocket can carry various warheads weighing up to 4.5 kilograms. The rocket is most often placed in 7- or 19-rail launchers. It can or could be used by a wide range of aircraft, including: UH-1 Huey, AH-1 Cobra, AH-64 Apache, F-16 Fighting Falcon or F / A-18 Hornet. At present, apart from the USA, it is used by the armed forces of many other countries, such as Australia, Egypt, the Netherlands and South Korea.
