The I.P.O.F., an acronym for Imperial Planetary Occupation Facility, represented a massive, pre-fabricated base of operations. These facilities were deployed to planets that the Galactic Empire had recently conquered and occupied. After being set down on a planet, the I.P.O.F. typically remained stationary. The Imperial Complex located on Lothal served as an example of such an I.P.O.F. Ultimately, it was destroyed when Rebel Alliance operatives propelled it into the atmosphere, causing a catastrophic explosion.
