The F-4 Kurnass
On the night of October 6–7, 1973, the pitch-black sky over the Gulf of Suez erupted with an impossible mission. Navigator Micha Oren sat in the backseat of an F-4 Kurnass, the Israeli variant of the American Phantom II, when a radio call came through: an Egyptian warship was shelling the Israeli fortifications at Ophir. The problem was simple and catastrophic—the Kurnass was configured for air-to-air combat with Sparrow missiles, not ground attack. No bombs, no cannons suitable for a ship, only the AIM-7 air-to-air missile in its racks. Oren made a calculated gamble. He remembered reading that American pilots had once used Sparrows against ships in Vietnam. Over the black gulf, with the radar painting the enemy vessel below, he guided his pilot through a diving attack that would redefine what was possible with a weapons system designed for dogfighting.
Brief Overview
The F-4 Kurnass—Hebrew for “Sledgehammer”—was the Israeli Air Force’s designation for the McDonnell Douglas F-4E Phantom II. Introduced to IAF service in 1969, the Kurnass filled a critical capability gap that the service’s primary fighter, the Mirage III, could not address: a large, fast, heavily armed aircraft equally capable of long-range combat air patrol and deep strike missions. Built by McDonnell Douglas in the United States, the Phantom entered service with the U.S. Air Force in 1964 and would become the most widely operated fighter-bomber of the Vietnam War era.
For Israel, which faced multi-front threats from Arab neighbors equipped with Soviet-supplied MiG-21s and SAM-2 air defense systems, the Phantom represented modern combat aviation capability at scale. While the Israeli Air Force (IAF) continued to rely on the delta-wing Mirage III as its primary day fighter, the Kurnass proved invaluable as a night-fighter, electronic warfare platform, and strike aircraft. The Yom Kippur War would expose both the aircraft’s strengths and the tactical innovations of the pilots who flew it.
Combat History
The Yom Kippur War: October 1973
When Egypt and Syria attacked Israel on October 6, 1973, the IAF had approximately 60 F-4E Kurnass aircraft distributed among four squadrons. Squadron 107, the nighttime interception force, drew the responsibility for defending the entire eastern coast of the Suez—a 50-mile (80 km) sector from Ras Sudar to Ophir with minimal ground-based air defense and only second-line ground forces in place.
During the first night of the war, the vulnerability of the Ras Sudar to Ophir sector was acute. Egyptian forces held the western bank and possessed both air capability and naval assets. No Israeli first-line reserve formations had yet deployed to counter them. The Kurnass crews of Squadron 107, operating from dispersed airfields, maintained continuous combat air patrol (CAP) sorties throughout the darkness, a mission in which the Phantom’s radar and sophisticated fire control system provided decisive advantage over the MiG-21’s visual-only night capability.
The Egyptian Ship and the Sparrow Gambit
On the night of October 6–7, Phantom navigator Micha Oren and pilot Gordon (surname not released in sources) launched on a CAP mission over the gulf. When ground control reported an Egyptian vessel shelling the fortifications at Ophir, they were vectored to investigate. The ship’s class and armament were unknown. The Kurnass carried no bombs and no anti-ship weapons—only AIM-7 Sparrow air-to-air missiles, designed to home on fighter-sized targets.
Over the sea, with no land clutter to blind the radar, Oren acquired the ship on the Phantom’s radar scope. He realized that a Sparrow missile, homing on radar reflections, could theoretically lock onto the larger radar echo of a ship—a concept he had read about in an Aviation Week article describing American anti-ship Sparrow shots during Vietnam. The pair executed multiple practice passes to refine dive angle and speed, then committed to a firing pass at approximately 20,000 feet (6,100 meters).
The missile launched and flew true—but impacted the water 10–15 miles (16–24 km) beyond the ship. The warship, either panicked or merely coincidentally altering course, turned away. Despite the miss, Oren and his pilot felt they had succeeded in their primary objective: they had driven off the threat. They pursued the fleeing vessel with long-range cannon fire before ground control diverted them northward.
The Israeli Helicopter Incident
While conducting their pursuit, ground control (RCU, the regional control unit) reported an unidentified radar contact crossing the gulf from west to east in the northern sector. The Kurnass crew rushed toward the contact at high speed. Oren detected a slow-moving, radar-small object—consistent with either a light aircraft or helicopter. He requested permission to open fire. The delay in authorization proved crucial: by the time clearance arrived, the contact had crossed from the gulf into Sinai airspace, where it disappeared into ground clutter.
The Phantom crew made five or six additional passes, achieving radar lock on several occasions, but the missile failed to launch on any pass. The aircraft being tracked was later identified as an Israeli helicopter, making the software malfunction or weapons hang a fortunate failure.
Combat Record Context
The F-4 Kurnass saw extensive service throughout the Yom Kippur War and subsequent Arab-Israeli conflicts. During the 1973 war, Israeli Phantoms claimed numerous air-to-air kills against Egyptian and Syrian fighters, though exact tallies remain disputed. The aircraft’s superior radar, two-engine reliability, and weapons load made it the IAF’s most effective counter to Arab numerical superiority. The incidents recounted by navigator Micha Oren typify the improvisation and tactical thinking required when facing multi-domain threats with limited resources—and illustrate the Phantom’s adaptability across mission sets for which it was not originally designed.
FAQ
What was the F-4 Kurnass?
The F-4E Kurnass (Hebrew: “Sledgehammer”) was the Israeli Air Force’s designation for the McDonnell Douglas F-4E Phantom II. Israel received approximately 200 Phantoms between 1969 and 1973, with F-4E models forming four dedicated squadrons by the Yom Kippur War. The aircraft served as the IAF’s primary long-range fighter-bomber, complementing the shorter-range Mirage III in the first-line inventory.
Did the F-4 Kurnass fight in the Yom Kippur War?
Yes, extensively. Squadron 107 (the fourth Kurnass squadron) operated continuous combat air patrol sorties during the first night of the war, October 6–7, 1973. Israeli Phantoms flew hundreds of sorties against Egyptian and Syrian targets throughout the conflict, claiming numerous air-to-air victories and executing ground-attack missions including strikes on radar sites and armored formations.
What made the Phantom effective in Israeli service?
The Kurnass’s two Pratt & Whitney J79 turbojets, advanced AN/APG-12 radar, and large weapons load (up to 16,000 lbs / 7,257 kg) provided the IAF with range, speed, and payload that the Mirage III could not match. The Phantom’s radar-guided AIM-7 Sparrow missiles gave Israeli pilots a technological advantage in beyond-visual-range (BVR) engagements, particularly valuable in nighttime operations where Arab fighters (mainly radar-less MiG-21s) fought blind.
How many F-4 Kurnass aircraft did Israel operate?
Israel acquired approximately 200 F-4E and F-4E(M) Phantoms between 1969 and 1982. These aircraft remained in service with the IAF into the 1990s, with some airframes later transferred to other allied nations or retired as more advanced fighters (F-15 and F-16) entered service.
Modeler’s Corner
Accurate representations of the Kurnass in 1973 Yom Kippur War markings exist across multiple scales. Academy’s 1/48 F-4E Kurnass offers excellent rivet detail and includes Israeli roundels and refueling probe; intermediate skill level. For collectors seeking rapid-build options, Revell Germany’s 1/72 F-4E Phantom II provides acceptable accuracy at beginner level, though tail decoration is simplified. Hasegawa’s 1/32 F-4E represents the ultimate reference model, with photo-etched detail and authentic cockpit instruments; advanced modeling required.
