McDonnell Douglas MD 500 Defender
military helicopter series of the MD 500 family by Hughes and MD Helicopters
The McDonnell Douglas Helicopter Systems MD 500 Defender is a light multi-role military helicopter based on the MD 500 light utility helicopter and OH-6 Cayuse Light Observation Helicopter.
Design and development
During the Vietnam War, the original OH-6 Cayuse helicopter performed admirably as a light helicopter. A market for light multi-mission helicopters with better equipment fit than the OH-6 and Model 500M was identified by the designers at Hughes. The resulting design was the Model 500MD Defender which first flew in 1976. It was tailored for specific roles including unarmed observation and an armed scout helicopter equipped with TOW anti-tank missiles. An anti-submarine version was developed with a search radar, magnetic anomaly detector and the capability to carry lightweight aerial torpedoes.
Customers like Kenya, who could purchase a functional anti-armor helicopter for less than half the price of a gunship such as the AH-1 Cobra or the AH-64 Apache, were drawn to the helicopter. Israel used the Defender extensively during the conflicts of the late 1970s and 1980s against Syrian armored forces.
The Defender was later built as an improved version as the MD530MG, with increased engine power, handling, avionics, and a redesigned forward fuselage. Later developments included a mast mounted sight (MMS).
