<p>During the second half of 2002, the <a href="Naval_Research_Laboratory" class="mw-redirect" title="Naval Research Laboratory">Naval Research Laboratory</a> studied the tactical application of space assets. Relatively new technologies and processes in the areas of <a href="Microsatellite_(spaceflight)" class="mw-redirect" title="Microsatellite (spaceflight)">microsatellites</a>, affordable and quick-response launch vehicles, and the classified <a href="SIPRNet" title="SIPRNet">SIPRNet</a> (Secret Internet Protocol Router Network) made tactical use of space assets possible in the relatively near term. The DoD's <a href="Office_of_Force_Transformation" title="Office of Force Transformation">Office of Force Transformation</a> (OFT) agreed with the core findings of the study and decided to start an <a href="Operationally_Responsive_Space" class="mw-redirect" title="Operationally Responsive Space">Operationally Responsive Space</a> (ORS) Initiative consisting of a series of experiments. TacSat-1 is the first experiment in this OFT initiative. The TacSat-1 experiment received go-ahead on 7 May 2003.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>
</p><p>The TacSat series of experimental spacecraft are designed to allow military commanders on a battlefield to request and obtain imagery and other data from a satellite as it passes overhead. Collected data will be delivered to field commanders in minutes rather than hours or days.
</p><p>All TacSats have been launched on <a href="Minotaur_(rocket_family)" title="Minotaur (rocket family)">Minotaur</a> <a href="Launch_vehicle" title="Launch vehicle">launch vehicles</a>.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>
