Even just get to the edge of space, then fire a satellite-killing missile?
Sure, but our goal was to get REAL “single stage to orbit” capability in which you could re-fuel the vehicle and go up again in weeks, not months or years like the Shuttle. Only then will you really have “routine” space travel.
Old news.
On 13 September 1985, Maj. Wilbert D. "Doug" Pearson, flying the "Celestial Eagle" F-15A 76-0084 launched an ASM-135 ASAT about 200 miles (322 km) west of Vandenberg Air Force Base and destroyed the Solwind P78-1 satellite flying at an altitude of 345 miles (555 km).
