Question: The 69 Squadron of the Israeli Air Force saw extensive action in which war between the Arab and Israeli fighters in 1973?
Context: The Battles of Fort Budapest (Hebrew: מעוז בודפשט‎ ‎ ) refer to two attempts by the Egyptian Army to capture Fort Budapest, part of the Bar Lev Line during the Yom Kippur War.  The first attempt took place at noon on October 6, 1973 with the start of Operation Badr, but failed due to Israeli Air Force intervention.  The second attempt took place on October 15, at the onset of Operation Stouthearted Men, the Israeli military operation to cross the Suez Canal.  Despite significant setbacks caused by poor sea conditions, the second attack was on the verge of success when the Israeli Air Force once again intervened, and this, coupled with Israeli reinforcements, repelled the Egyptian attack. No 501 Squadron was the fourteenth of the twenty-one flying units in the Royal Auxiliary Air Force, the volunteer reserve part of the British Royal Air Force.  The squadron won seven battle honours, flying Hurricane, Spitfire and Tempest fighter aircraft during World War II, and was one of the most heavily engaged units in RAF Fighter Command.  In particular, the Squadron saw extensive action during the Battle of France and Battle of Britain.  At present the unit is not flying any more and has a Force Protection role. The Israeli Air Defense Command (in Hebrew: מערך ההגנה האווירית) is the Israel Defense Forces unit responsible for the surface front of Israel's air defense, complementing the air defense provided by Israeli Air Force squadrons.  Initially a part of the IDF Artillery Corps, since 1970 the Air Defense Command has been subordinate to the Israeli Air Force. Gordon Levett (1921–2000) was a former Royal Air Force pilot in World War II who volunteered for a covert mission to fly supplies including dismantled fighter planes into the fledgling state of Israel in its War for Independence.  Later Levett joined the first squadron of the newly created Israeli Air Force, helping establish a permanent Israeli military and aiding in the founding of the state of Israel.  Levett was the only English gentile pilot in the Israeli Air Force, where he rose to the rank of lieutenant colonel. Hatzerim Israeli Air Force Base (Hebrew: בָּסִיס חֵיל-הַאֲוִויר חֲצֵרִים‎ , "Bsis Heil HaAvir Hatzerim") (ICAO: LLHB) is an air base of the Israeli Air Force in the Negev Desert on the west outskirts of Beersheba, near Kibbutz Hatzerim.  The base was constructed during the early 1960s and declared operational on 3 October 1966, the first air base located on a former Royal Air Force base.  At Hatzerim is the Israeli Air Force Museum, which opened in 1977 and has allowed public access since June 1991.  The IAF Flight Academy has been housed at Hatzerim since April 1966 and the IAF Aerobatic Team is located there as well. No. 75 Squadron is a Royal Australian Air Force (RAAF) fighter unit based at RAAF Base Tindal in the Northern Territory.  The squadron was formed in 1942 and saw extensive action in the South West Pacific theatre of World War II, operating P-40 Kittyhawks.  It was disbanded in 1948, but reformed the following year and operated jet aircraft throughout the Cold War.  The squadron was based at Malta from 1952 to 1954, flying de Havilland Vampires, and Malaysia from 1968 to 1983, with Dassault Mirage IIIs, before returning to Australia. Giora Romm (Hebrew: גיורא רום‎ ‎ , born 1945) is a former deputy commander of the Israeli Air Force (IAF), Israel's former military attaché in the United States and the current director of the Civil Aviation Authority of Israel.  Romm was the Israeli Air Force's first jet ace, scoring five kills during the 1967 Six Day War.  In 1969, during the War of Attrition, Romm was shot down and spent several months in Egyptian captivity.  He commanded the IAF's 115 Squadron through the intensive fighting of the 1973 Yom Kippur War and participated in Operation Wooden Leg, the 1985 raid against PLO headquarters in Tunisia. The Yom Kippur War, Ramadan War, or October War (Hebrew: מלחמת יום הכיפורים‎ ‎ , "Milẖemet Yom HaKipurim ", or מלחמת יום כיפור", Milẖemet Yom Kipur "; Arabic: حرب أكتوبر‎ ‎ , "Ḥarb ʾUktōbar ", or حرب تشرين , "Ḥarb Tišrīn "), also known as the 1973 Arab–Israeli War, was a war fought by a coalition of Arab states led by Egypt and Syria against Israel from October 6 to 25, 1973.  The fighting mostly took place in the Sinai and the Golan Heights, territories that had been occupied by Israel since the Six-Day War of 1967.  Egyptian President Anwar Sadat wanted also to reopen the Suez Canal.  Neither specifically planned to destroy Israel, although the Israeli leaders could not be sure of that. Nevatim Israeli Air Force Base (Hebrew: בסיס נבטים‎ ‎ ) (IATA: VTM, ICAO: LLNV) , also Air Force Base 28, is an Israeli Air Force base located southeast of Be'er Sheva, near moshav Nevatim.  It was built as a rough runway in 1947 for the Sherut Avir, the air wing of the Haganah, and was named Malhata.  It was reopened in 1983 as a new modern airbase with two runways as the result of joint Israeli and US government funding as part of the IAF's redeployment out of its bases in the Sinai after it was returned to Egypt following the Camp David Accords.  Since 2003 the base has gradually received more squadrons of F-16s.  A third runway was built in the mid-2000s decade as part of a project to accommodate the transfer of military activities previously taking place at Ben Gurion Airport (Air Force Base 27) to Nevatim. 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.
