Fourth mission dedicated to United States Department of Defense, and first flight of Columbia since mission STS-61-C. Due to the nature of this mission, details are classified. Believed to have deployed two satellites, possibly including one second-generation Satellite Data System relay.
It has been reported that STS-28 also deployed an Advanced KH-11 photo-reconnaissance satellite that used an all-digital imaging system to return pictures. The satellite was placed into a low earth orbit with a high-inclination to the equator to allow coverage of most of the Earth's surface. The KH-11 series is a digital imaging photo- reconnaissance satellite with both visual and infrared sensors.

Oh yeah, during that trip to Houston I had a casual conversation with one
of the astronauts who flew on the STS-28 mission. We were talking about
practically everything under the sun, and he casually remarked that in all
of the speculation in the press about the STS-28 DoD payload he did not see
a single story which correctly identified the payload.
