By contrast, the F-15 Eagle which was another fighter aircraft of that era was designed for air superiority and interception, with the mantra "not a pound for air to ground", although the F-15C did have a rarely used secondary ground attack capability. That program eventually evolved into the F-15E Strike Eagle interdictor/strike derivative which retained the air-to-air combat lethality of earlier F-15s.
In contrast to other fighter aircraft from that era, such as the F-15 Eagle, which was designed for air superiority and interception with a focus on "not a pound for air-to-ground", the F-15C had a limited ground attack capability. However, this concept evolved into the F-15E Strike Eagle, maintaining the earlier model's air combat effectiveness.
