The Strategic Training Route Complex is a series of training routes operated by the United States Strategic Command where bomber aircraft are able to train using tactics for low-level flight. During the Cold War, fourteen routes were operated by the 99th Strategic Weapons Wing.[1] Range control was provided by the 25th Strategic Training Squadron (now known as the 25th Space Range Squadron).[2] The current routes are located in Wyoming, South Dakota, North Dakota, and Montana.[3] One downside to the routes being out west, is that it made it prohibitive for units in the Eastern United States to travel west without expending flight hours.[4]
