In December 2025, Ukrainian F-16s intercepted 97% of Russian cruise missiles. Technical analysis of an unexpected and decisive effectiveness.
Summary
During Russia’s massive attack on the night of December 22-23, 2025, the Ukrainian air force claimed a result that surprised many observers: 34 cruise missiles shot down out of 35 launched by F-16s, an interception rate of 97%. This figure silenced some of the critics who considered the versions delivered to Ukraine to be outdated. The event highlights an often overlooked reality: in the hunt for cruise missiles, the modernity of an aircraft matters less than its integration into a coherent system combining sensors, intelligence, doctrine, and ground-air coordination. The F-16s proved particularly well suited to this defensive mission, which was crucial for protecting energy infrastructure in the middle of winter. This success was neither accidental nor miraculous. It was the result of targeted use, methodical preparation, and an operational environment that transformed a fighter jet considered obsolete into a key tool for Ukrainian air defense.
The operational context of the Russian attack in December 2025
On the night of December 22-23, 2025, Russia launched a coordinated attack targeting primarily Ukrainian energy infrastructure. The objective was clear: to cause lasting disruption to electricity production and distribution in the middle of winter, when demand reaches critical peaks.
The missiles used were mainly subsonic cruise missiles, flying at low altitude, designed to saturate defenses and exploit gaps in radar coverage. These weapons, although less spectacular than ballistic missiles, pose a constant threat due to their accuracy and ability to bypass surface-to-air systems.
In response to this attack, Ukraine launched a multi-layered defense combining ground-to-air systems and fighter jets. It was in this context that the F-16s played a central role.
The F-16 as a cruise missile hunter
The F-16 Fighting Falcon was never originally designed as a dedicated missile defense interceptor. However, its characteristics make it an effective candidate for cruise missile hunting.
Its maximum speed exceeds Mach 2 (approximately 2,470 km/h), but it is above all its ability to operate at medium altitude, with excellent maneuverability and high availability, that makes it relevant. Unlike heavier fighters, the F-16 can be deployed quickly, redeployed frequently, and maintained with relatively limited resources.
In the Ukrainian context, these qualities have made it possible to increase the number of defensive air patrols positioned on the likely missile arrival routes.
Why older F-16s are not “obsolete” in this role
One of the major lessons learned from this episode is the relativity of the concept of obsolescence. The F-16s delivered to Ukraine are not latest-generation aircraft. However, in a very specific role, they are proving to be highly effective.
Hunting cruise missiles does not require extreme stealth or advanced sensor fusion. Above all, it requires good detection, rapid interception capability, and seamless integration with ground-based radars.
The F-16s benefit from modernized radars capable of detecting low-altitude targets and, above all, proven compatibility with air-to-air missiles adapted to this type of threat. In this context, the relative simplicity of the aircraft becomes an operational advantage.
The decisive role of sensor integration
The claimed interception rate cannot be understood without analyzing the detection architecture. The F-16s did not operate alone. They relied on a network of ground radars, remote sensors, and command centers capable of providing a consolidated aerial picture.
Cruise missiles often fly at less than 100 meters altitude, exploiting terrain and radar masking. Early detection therefore relies on multiple sensors and their networking. Once the threat has been identified, the F-16s can be precisely vectored toward the likely trajectories.
This coordination reduces search time and significantly increases the probability of interception.
Air-to-air weapons used in the mission
Weapons play a key role in the hunt for cruise missiles. Ukrainian F-16s use radar- or infrared-guided air-to-air missiles, optimized for engaging slow-moving, low-maneuverability targets.
A subsonic cruise missile typically flies at speeds between 700 and 900 km/h, much slower than a fighter jet. This difference allows the F-16 to choose its engagement conditions, intercepting the target from the front or from the side.
The unit cost of these missiles remains high, but it is incomparable to the damage that a cruise missile can inflict on a power plant or transformer station.
A doctrine of use adapted to territorial defense
The effectiveness of the F-16s is also based on a clear doctrine. The aircraft are not used as offensive fighters, but as defensive interceptors, integrated into an overall strategy for protecting the territory.
Patrols are positioned deep behind the front lines in order to preserve the aircraft and maximize their endurance. Engagements are carefully selected, avoiding areas saturated with enemy air defenses.
This pragmatic approach contrasts with some more offensive Western doctrines, but it perfectly matches Ukraine’s immediate needs.
Complementarity with ground-to-air systems
It would be wrong to attribute all the success to the F-16s alone. Ukraine’s ground-to-air defense plays an essential role in filtering the threat and saturating certain trajectories.
Surface-to-air systems, which are more economical in the long term, are often used against the most accessible targets. The F-16s intervene as a complement, particularly when missiles escape surface-to-air coverage or when an aerial interception offers a better probability of success.
This complementarity makes it possible to optimize available resources, reserving the most expensive means for the most critical threats.
A direct impact on the protection of energy infrastructure
The success of this massive interception had an immediate effect on the protection of Ukraine’s power grids. Each missile shot down means a facility preserved, hours of outages avoided, and reduced pressure on repair crews.
In winter, the continuity of the electricity supply becomes a matter of national resilience. The role of the F-16s then goes beyond the military sphere to directly affect the country’s economic and social stability.
This direct link between air defense and civil protection explains the strategic importance attached to these missions.
Limitations and conditions for reproducibility
An interception rate of 97% is remarkable, but it should not be interpreted as a permanent guarantee. Several factors worked in Ukraine’s favor during this attack: a limited number of missiles, relatively predictable trajectories, and specific preparation.
Faced with more massive saturation or faster missiles, the results could be different. Success also depends on the availability of aircraft, the stock of air-to-air missiles, and the quality of upstream intelligence.
The reproducibility of this success therefore requires a constant effort to maintain conditions and train crews.
How this operation has changed perceptions of the F-16
This episode has profoundly changed perceptions of the F-16 in the Ukrainian conflict. The aircraft is no longer seen as a political symbol or a compromise by default, but as a credible operational tool in a well-defined role.
It serves as a reminder of a fundamental lesson from military history: the relevance of a weapons system depends as much on its use as on its technological level. An older aircraft, well integrated and properly used, can prove more effective than a more modern platform that is ill-suited to the mission.
A broader lesson for modern air defense
The hunt for cruise missiles is set to become a central mission for many air forces. The attacks of December 2025 show that existing aircraft, when properly modernized and integrated, can play a decisive role.
The Ukrainian case illustrates an efficient and pragmatic approach to air defense. It highlights the importance of doctrine, coordination, and clarity of objectives.
In a context of constrained budgets and multiple threats, this lesson extends far beyond the conflict in Ukraine.
