This thesis examines the performance of the Cooperative Logistics Supply Support Arrangement (CLSSA) for Republic of Korea Air Force (ROKAF). As one of the biggest FMS customer countries, ROKAF buys a substantial portion of its weapon systems from the U.S. Government and relies on the follow-on supply support from the source of acquisition. Because of the advantage of the CLSSA program for its timely support to foreign countries, the CLSSA has been the preferred method of follow-on supply support for FMS customer countries and its magnitude and coverage are being increased. To find out the level of supply support for ROKAF, the programmed ratio of requisitions was summarized and the requisition fill times were analyzed statistically against key variables: programmed vs. non-programmed and priority of requisitions. The transportation time portion of the CLSSA program was also measured against different modes of shipment. For the statistical comparisons, one year's requisition data for 1996 were obtained from Air Force Security Assistance Center in AFMC, WPAFB OH. With the use of large sample z-tests, the statistical tests were performed; confidence intervals were constructed for the actual transportation times. The test results showed that the programmed ratios of the CLSSA requisitions were increased significantly after the change in application of Stock Level Quantity and Eligible-to-be Programmed Quantity in 1994 over all FMS countries. Although the programmed requisitions were shown to be faster than non-programmed ones except for requisitions of high priority, the priority factor was not shown to play an expected role in requisition filling process. The transportation time was observed to be moderate depending on the specified modes of shipment.
