- Hydra 70
[
AGM-114 Hellfire missile.]The Hydra 70 rocket is a weapon derived from the 2.75 inch (70 mm) "Folding-Fin Aerial Rocket" (
Mk 4/Mk 40 Folding-Fin Aerial Rocket ) developed by the U.S. Navy for use as a free-flight aerialrocket in the late 1940s.Overview
The Hydra 70 family of WAFAR (Wrap-Around Fin Aerial Rocket), based around the Mk 66 universal motor was developed from the previous 2.75 inch Mk 40 motor-based FFAR (Folding Fin Aerial Rocket). The Mk 40 was originally used during the Korean and Vietnam wars, beginning a rich history of providing close air support to ground forces from about 20 different firing platforms, both fixed-wing and armed helicopters, by all U.S. armed forces. Today, the OH-58D(R) Kiowa Warrior and AH-64D Apache Longbow carry the Hydra rocket launcher standard on its weapon pylons. To provide some stability the four rocket nozzles were scarfed at an angle to impart a slight spin to the rocket during flight.
Mk 66 rocket motor variants
Common warheads
NOTE: Some of the warheads described were designed for the older Mk 40 rocket motor, but most likely could work with the Mk 66 motor if upgraded or modernized models were not available.Fact|date=April 2008
Precision guided Hydra 70
The
Advanced Precision Kill Weapon System (APKWS) II was a program to provide alaser guided missile which would have been compatible with the existing Hydra 70 systems in service. It was cancelled in February 2007.
