AGM-63
The AGM-63 was an American air-to-surface missile that was intended to combat ground-based radar systems . However, the missile did not come out of the planning phase.
The project started in March 1962 when the US Navy identified a need for two anti-radar missiles (ARM). These should complement the AGM-45 Shrike , which has only a short range. The first (ARM I) should have a range of up to 90 km, while the second (ARM II) should have a range of over 180 km. The development of the ARM I was approved in 1963 and was given the designation ZAGM-63A. However, the funds available went to other ARM programs such as the AGM-45 Shrike Enhancement. The development of the AGM-78 Standard ARM and the AGM-88 HARM was also seen as much more important and urgent than a completely new development.
The development of the AGM-63 continued over several years, especially in the theoretical area. Neither a prototype nor a case has been tested in practice. The project was finally ended in early 1970.
