Sept. 27, 2011: The Office of Naval Research-sponsored tactical satellite IV (TacSat-4) lifts-off from the Alaskan Aerospace Corporation's Kodiak Launch Complex aboard a Minotaur IV+ launch vehicle.
A joint military team used a Minotaur IV+ rocket — essentially a decommissioned Peacekeeper missile built decades ago during the Cold War -— to successfully launch, at 8:49 a.m. PDT today from Alaska Aerospace Corporation’s Kodiak Launch Complex, the TacSat-4 satellite into orbit. The microsatellite will enable "on the move" communication, (COTM) relaying calls and data directly to the handheld radios currently in use by nearly every branch of the military.
Developed by the Naval Research Laboratory for the Office of Naval Research and the Operationally Responsive Space Office, TacSat-4 will enable deployed military members utilizing hand-held radios to contact and task the experimental asset even in many, now problematic, mountainous and urban areas. The tiny satellite weighs 990 pounds versus the industry average of about 4,300.

In Afghanistan and other spots, mountainous terrain makes communications with hillside base stations challenging. In recent years, one special ops solider was killed trying to radio for support, his handheld unable to communicate with an nearby antenna. TacSat-4 might have been the difference between life and death.
