The 100th Shipborne Fighter Aviation Regiment (Military Unit Number 45782) was an aviation regiment of the Soviet Navy and the Russian Navy. For most of its time active, it flew the Sukhoi Su-27 and Mikoyan MiG-29.
It was formed at Saki in the Crimea on 10 March 1986. In January 1992 its personnel refused to take the oath of loyalty to Ukraine, which would have presumably made them part of the Ukrainian Navy or Ukrainian Air Force, and instead its personnel left for Russia, leaving their aircraft and equipment behind. The unit regrouped at Severomorsk-3 as part of the Northern Fleet. However, in February 1993 the regiment was disbanded and its personnel and equipment incorporated into the 279th Shipborne Fighter Aviation Regiment.
