By the spring of 1982 tensions had risen again and the attempted assassination of the Israeli ambassador to London Shlomo Argov on June 3, 1982, prompted Israel to launch Operation Peace for Galilee. 69 Squadron flew 27 sorties in the preparation phase for the operation, from June 4 to the actual beginning of the invasion on June 6. The first of these were carried out on the afternoon of June 4, when a 4-ship formation struck the stadium in Beirut, used as a PLO weapons depot. Once Israeli ground forces began pushing into Lebanon, 69 Squadron provided close air support. One aircraft was damaged by enemy flak on the first day of the invasion, and two suffered landing accidents, but with poor weather and a shortage of targets, there was initially little fighting to be done. This changed on June 8 when it became apparent the Syrian forces in Lebanon would have to be engaged, and that same afternoon two squadron Phantoms bombed a Syrian electronic warfare facility on Jabel Barouk.
