More than half a century after the Israeli-designed Kfir fighter first entered military service, the aircraft has returned to the skies over Sri Lanka in a dramatically modernized form, marking a significant milestone for one of the world’s last remaining operators of the iconic combat jet.
The Sri Lankan Air Force (SLAF) recently conducted the maiden flight of its first upgraded Kfir C.12 fighter aircraft following an extensive modernization program carried out in partnership with Israel Aerospace Industries (IAI). The successful flight signals the beginning of a new chapter for an aircraft that has played a crucial role in Sri Lanka’s military history and remains a cornerstone of its limited combat aviation capabilities.
The modernization effort stems from a US$50 million agreement signed between Sri Lanka and IAI in 2021, aimed at extending the service life of the aging fleet while significantly enhancing its combat effectiveness. The program upgrades Sri Lanka’s surviving Kfir aircraft—primarily C.2 and C.7 variants acquired during the mid-1990s—to the more advanced C.12 Block 60 standard.
Known affectionately within the SLAF as the “Lion Club,” the Kfirs are operated by the 10th Fighter Squadron based at SLAF Base Katunayake. Although once a formidable component of Sri Lanka’s air power, years of attrition, aging systems, and budgetary constraints reduced the fleet to only five operational aircraft, making modernization a practical necessity rather than a luxury.
According to the SLAF, the upgraded aircraft successfully completed its first flight after an extensive period of ground validation, systems integration, and testing. Officials described the event as a “significant milestone in the ongoing modernization of the nation’s fighter fleet,” paving the way for similar upgrades across the remaining aircraft.
The modernization package represents a substantial technological leap for an aircraft whose origins date back to the Cold War. At the heart of the upgrade is a modern glass cockpit, replacing legacy analog instrumentation with digital displays that improve situational awareness and pilot efficiency. New mission systems, communication suites, navigation equipment, and advanced avionics have also been integrated into the aircraft.
The upgraded Kfir now possesses enhanced mission planning and debriefing capabilities, improved targeting systems, and compatibility with precision-guided munitions. These improvements are designed to reduce pilot workload while increasing mission effectiveness and operational flexibility.
Beyond avionics, the modernization program has also addressed the structural challenges associated with maintaining aircraft that first flew decades ago. Speaking about the project, IAI Chairman Boaz Levy emphasized that engineers reinforced the airframe and replaced obsolete components that are no longer commercially available.
“We reinforced the aircraft’s structure and replaced outdated components that are no longer available, since the aircraft was originally developed in the 1960s,” Levy said. “The upgraded aircraft now features a new mission computer, autopilot, advanced navigation and avionics systems, and a refurbished engine that provides improved performance.”
Levy highlighted the unique relationship between Sri Lanka and the Kfir, noting that the aircraft continues to enjoy a remarkable reputation within the country despite its age.
“Sri Lanka is very fond of this aircraft, and it serves its needs exceptionally well,” he said. “Since the Kfir entered service there, many children born in the country have even been named ‘Kfir.’ Decades after most of these aircraft were retired elsewhere, we continue to maintain the unique expertise and capabilities required to upgrade them.”
For Sri Lanka, the modernization program offers a cost-effective solution to a longstanding defense challenge. The country’s defense budget has remained constrained by broader economic pressures, with personnel expenditures consuming a large share of available resources. Purchasing a new generation of fighter aircraft would require investments far beyond current financial realities.
In 2016, the Sri Lankan government approved plans to acquire between eight and twelve new multirole combat aircraft through government-to-government agreements. Potential candidates included India’s Tejas light combat aircraft and the Chinese-Pakistani JF-17 Thunder. While discussions advanced, particularly regarding the JF-17, the acquisition ultimately stalled amid budget reductions, shifting defense priorities, and regional geopolitical considerations.
Against this backdrop, upgrading existing Kfirs emerged as a far more affordable alternative. While new-generation fighters can cost between US$40 million and US$70 million per aircraft, Sri Lanka’s entire fleet modernization program costs approximately US$50 million. The upgraded jets are expected to provide a credible air-defense and multirole capability for years to come.
The Kfir’s importance to Sri Lanka extends beyond economics. During the country’s decades-long conflict against the Liberation Tigers of Tamil Eelam (LTTE), the aircraft became one of the SLAF’s most important combat assets.
From the late 1990s through the final stages of the civil war in 2009, Kfirs conducted extensive strike missions against LTTE targets. The aircraft attacked command centers, artillery positions, ammunition depots, fuel storage facilities, troop concentrations, reinforcement routes, and maritime assets used by the insurgent group.
According to SLAF accounts, the fighter’s combination of speed, payload capacity, and strike precision played a significant role in supporting ground offensives while helping reduce casualties among government forces.
However, the conflict also underscored the vulnerability of valuable air assets. At least two Kfir fighters were destroyed on the ground during an LTTE attack on an airbase, while several others were lost in non-combat accidents over the years. These losses gradually reduced the fleet’s size and increased the urgency of preserving the remaining aircraft.
The Kfir itself occupies a unique place in aviation history. Its origins lie in one of Israel’s most challenging strategic moments.
Before the late 1960s, Israel relied heavily on France as a supplier of advanced combat aircraft, including the highly successful Dassault Mirage III fighter. However, following the 1967 Six-Day War, France imposed an arms embargo on Israel and suspended delivery of 50 Mirage 5 aircraft that Israel had already purchased.
Faced with an urgent need to maintain its military edge while cut off from a key supplier, Israel embarked on an ambitious indigenous fighter development effort. The result was first the Nesher fighter and later the more advanced Kfir.
Although heavily influenced by the Mirage 5 design, the Kfir incorporated significant modifications and improvements. Most notably, Israeli engineers replaced the original French powerplant with the American-made General Electric J79 turbojet engine, the same engine used in several U.S. combat aircraft.
The more powerful engine transformed the aircraft’s performance. The Kfir achieved speeds exceeding Mach 2, reaching approximately 1,520 miles per hour. It possessed a service ceiling of more than 58,000 feet and a climb rate approaching 46,000 feet per minute, making it one of the most capable fighters in its class during the 1970s.
The aircraft was equipped with the Elta EL/M-2001 fire-control radar, providing look-down and shoot-down capability, and carried an impressive weapons load. Armed with two 30mm DEFA cannons and capable of carrying more than six tons of external stores, the Kfir could employ a wide variety of weapons, including air-to-air missiles, anti-radiation missiles, precision-guided munitions, and unguided bombs and rockets.
Despite its impressive capabilities, the Kfir’s frontline service within the Israeli Air Force proved relatively brief. It achieved its only confirmed aerial victory in Israeli service in July 1979 when a Kfir shot down a Syrian MiG-21 over Lebanon using a Shafrir-2 missile.
By the early 1980s, however, newer aircraft such as the F-15 Eagle and F-16 Fighting Falcon began replacing the Kfir in frontline roles. Although it continued to participate in military operations, including missions over Lebanon, the aircraft gradually gave way to more advanced fighters.
After nearly two decades of service, Israel retired the Kfir from active frontline duty during the 1990s. Yet retirement did not mark the end of its career.
The aircraft found a second life on the international market, serving with countries such as Colombia, Ecuador, and Sri Lanka. It also attracted interest from the United States, where the U.S. Navy and Marine Corps leased Kfir aircraft for adversary training.
American pilots valued the aircraft for its ability to simulate Soviet fighters, particularly the MiG-23 Flogger. Former U.S. Navy pilot Captain John Manning described the Kfir as an effective stand-in for Soviet aircraft due to its acceleration and high-speed performance.
The Navy operated the aircraft until 1988 before replacing it with the F-16N, while the Marine Corps continued flying Kfirs until 1989 when they transitioned to the F-5E Tiger II.
Today, Israel’s air force has moved far beyond the Kfir era, operating advanced fleets of F-15s, F-16s, and F-35I stealth fighters. Yet the aircraft remains a testament to the ingenuity that emerged from necessity during a period of international isolation.
For Sri Lanka, that legacy remains very much alive. As Colombia moves forward with plans to replace its own Kfirs with modern Saab Gripen E/F fighters, Sri Lanka is poised to become the final operator of the Cold War-era jet.
The successful first flight of the upgraded Kfir C.12 demonstrates that even aircraft conceived more than five decades ago can remain operationally relevant when combined with modern technology. For a nation seeking affordable airpower amid fiscal constraints, the modernization provides a practical solution while preserving an aircraft that has become deeply woven into the history of the Sri Lankan Air Force.
