Development of Kefir: From Deathstrom Rashfire to Airframe

Israel, known for its prowess in military innovation, developed the Kefir, a formidable fighter jet. It all started with the transformation of the Deathstrom Rashfire airframe, which was equipped with domestic electronics and engines. The United States played a significant role by providing crucial support and components for the development of the Kefir. As Israel faced an arms embargo from France in the 1960s, the Kefir became a vital breakthrough in Israel's military aviation industry. Let's explore the journey of the Kefir and its impact on Israel's defense capabilities.

The Kefir, often regarded as the first brick for Israel's military aviation industry, was a response to the French arms embargo imposed on Israel in 1967. This embargo aimed to prevent the delivery of Mirage and Mystère fighter jets to Israel. In the face of restricted arms supply from Europe, Israel had to rely on its own capabilities to safeguard its national security. Thus, the Kefir project became an important promise for Israel to establish a domestic aircraft industry and reduce its dependence on foreign countries.

The Transformation of the Israeli Aircraft Industry

Initially, Israel responded to the arms embargo by producing unlicensed fighter aircraft based on the airframe and engine specifications collected by Israeli intelligence agencies. As a result, the Deathstrom Rashfire, later developed into the Kefir, became the cornerstone of Israel's aircraft industry. In 1973, the field prototype of the Kefir took its first flight, marking a significant milestone in Israel's aviation history. The Kefir C2 variant was eventually put into service in 1975, serving as a fighter-bomber under the Israeli Air Force's purview.

Kefir's Design and Features

With its overall design closely resembling the French Mirage 5, the Kefir boasted a delta-wing configuration, providing excellent lift and maneuverability. The main wings were positioned low on the fuselage, resulting in reduced surface area that contributed to enhanced performance. The Kefir featured a pair of canard wings attached to the front of the main wings, optimizing handling and providing additional lift during low-speed operations.

The Kefir underwent several design changes to accommodate the new American J79 engine, which necessitated a complete redesign of the rear fuselage and cooling system. The forward fuselage was extended to house advanced avionics, including the LTA 2001B Raider and a new weapons navigation system.

The Powerful J79 Jet Engine

One of the key elements that contributed to the Kefir's exceptional performance was its engine, the General Electric J79. Israel began procuring J79 engines from the United States in 1969, along with a production license. Compared to the French alternate engine, the J79 provided greater thrust and consumed less fuel, making it an ideal choice for the Kefir. The J79 engine delivered drive thrust of up to 49 kilonewtons and an afterburning thrust of 83.4 kilonewtons, propelling the Israeli fighter jet to reach a maximum speed at Mach 2.

Kefir's Performance and Capabilities

The Kefir showcased impressive capabilities in terms of combat range, speed, and altitude. With a combat range of 768 kilometers, the Kefir could operate far beyond Israeli borders. It boasted a service ceiling of 17,689 meters, granting it access to higher altitudes. Additionally, the Kefir possessed a remarkable rate of climb, reaching 233 meters per second.

Kefir's Weapons Systems and Armament

Equipped with a variety of weapons, the Kefir was a versatile fighter jet capable of engaging both air and ground targets. It featured a pair of DEFA 553 cannons, each loaded with between 120 and 140 rounds. The Kefir could be armed with guided air-to-ground rockets, including the powerful JL-100 rocket pack and the versatile 68mm rockets. For air-to-air missions, the Kefir could be outfitted with two AIM-9 Sidewinders or Python series L2A missiles. Additionally, it could carry anti-radiation missiles, such as the HDM-65, and a range of bombs, including laser-guided ones.

Kefir's Legacy: Air Superiority and Combat Action

The Kefir proved its worth in the Israeli Air Force, ensuring air superiority and achieving notable combat victories. Its first recorded air victory occurred on June 27, 1979, when a Kefir C2 successfully shot down a Syrian MiG-21. During the Israeli invasion of southern Lebanon in 1982, the Kefir played a significant role alongside the F-15 Eagle and F-16 Fighting Falcon in air superiority missions. As a result, the Kefir began to be upgraded to the C7 version, enhancing its performance as a fighter-bomber.

Upgrades, Export, and Future Prospects

In the late 1990s, the Kefir gradually phased out of active duty in the Israeli Air Force after nearly two decades of continuous service. However, its legacy and impact continue to resonate. As an American-designed and licensed engine, all export deals involving the Kefir are subject to prior approval from the U.S. Department of Defense. Despite these limitations, the Kefir found its way to foreign nations, with Ecuador, Colombia, and Sri Lanka among the countries that procured and utilized this exceptional fighter jet.

The future of the Kefir remains promising. In 2014, Israel announced plans to restart the production line of the Kefir Block 60 to serve the export market. With its proven track record and ongoing upgrades, the Kefir remains a significant asset for the Israeli defense industry and a symbol of Israeli ingenuity and determination.
