RF-4B Sensor Update Refurbishment Effort

The RF-4B is a U. S. Marine Corps aircraft which has the specific mission of conducting aerial reconnaissance missions in support of Fleet Marine Corps and U. S. Navy operations. The RF-4B has been in service for approximately 10 years, and consequently has used up most of its originally planned service life. The Sensor Update Refurbishment Effort (SURE) will extend the aircraft service life into the early 1990's and will additionally improve its mission capability through replacement of obsolescent avionics systems. Accordingly, the SURE program is comprised of two basic efforts: The incorporation of state-of-the-art reconnaissance/navigation/communications systems; and refurbishment of the aircraft (rewiring, cor-rosion elimination, and basic structural integrity improvements).
