(9) (SNF) Attacks against shipping in the latter part of 1987 and the first part of 1988 marked the most intensive anti-shipping operations by Iran during the war. The predominant Iranian attack platforms during this period were small boats employing 107mm rocket launchers, rocket propelled grenades, and small arms. Because of the use of various conventional and unconventional tactics, Iranian intentions in the Gulf were suspect at all times. (IO Exhibit 14, FOSIF WESTPAC 060847Z May 88).
U

U
(1) (SNF) In retaliation for the mining of USS SAMUEL B. ROBERTS, the United States attacked the Iranian Sirri and Sasson offshore oil production facilities in the SPG on 18 April 1988. In response to the U.S. operation, Iranian aircraft and warships deployed from Bandar Abbas to join Iranian Revolutionary Guard Corps (IRGC) small boats from Abu Musa Island and Qeshm Island in attacks on U.S. owned or associated oil rigs, platforms and jack-up rigs. During the engagement with U.S. forces, 2 Iranian frigates and 1 missile patrol boat were sunk or severely damaged. Eleven F-4s scrambled during the day from Bandar Abbas. USS WAINWRIGHT launched missiles at one of the aircraft, damaging it when the aircraft failed to respond to repeated warnings and continued to close the ship (IO Exhibit 14, Intelligence Background Briefing).
