The 69 "Hammers" Squadron is an Israeli Air Force squadron operating the F-15I Thunder out of Hatzerim. It was formed in July 1948 to operate three B-17 Flying Fortresses which the fledgling Israeli Air Force had acquired in the United States. The squadron flew the Flying Fortress, a type credited with propelling the IAF into the realm of modern aerial warfare, during both the 1948 Arab–Israeli War and 1956 Suez Crisis. Disbanded in early 1957, 69 Squadron reformed in 1969 to fly the F-4 Phantom II. 69 Squadron operated the "Kurnass" (Sledgehammer), as the Phantom was known in Israel, for 25 years and its Phantoms saw extensive action during the War of Attrition, Yom Kippur War, First Lebanon War and numerous engagements in between. The squadron often played a central role in IAF suppression of enemy air defences (SEAD) efforts and took part in repeated battles against Egyptian and Syrian air defence arrays.
