There were plenty, the military missions existence and classified nature weren't classified themselves. (Or at least plenty enough weren't. We wouldn't necessarily know of ones that were.)

So the "classified DOD project xyz" tasks are listed right there on the published official mission lists and schedules, and quite easy to look up on both Wikipedia and straight from NASA.

But the thing not achieved was Vandenberg launches, which would allow more N-S polar orbits that are often more useful to the military.

The less official but still obvious thing not achieved was the Airforce building a manned military space station (as far as we know...).
