Introduction
The Sukhoi Su‑24, NATO reporting name “Fencer”, is one of the most distinctive and historically significant combat aircraft ever developed by the Soviet Union. Conceived during the height of the Cold War, the Su‑24 was designed to meet a pressing strategic need: a supersonic, all‑weather, low-level tactical bomber capable of penetrating defended airspace and delivering precision strikes under any conditions. Its operational history spans more than five decades and multiple theatres of conflict, and as of the mid‑2020s the aircraft remains in service with several air forces – a testament to its utility even as newer platforms enter the skies.
Design Origins and Technical Features
Cold War Imperatives
In the late 1960s, Soviet military planners recognized a need for a dedicated tactical bomber that could operate at low altitudes to evade radar and deliver a combination of conventional and nuclear ordnance with precision. This requirement gave rise to the Sukhoi Su‑24, designed by the Sukhoi Design Bureau as a direct analogue to Western swing‑wing aircraft such as the U.S. General Dynamics F‑111 and the Anglo‑Italian Panavia Tornado IDS.
Technical Architecture
The Su‑24’s most noticeable technical feature is its variable‑geometry wings, which allow the aircraft to optimize aerodynamic performance across a wide range of speeds and flight regimes. With wings fully extended, the Su‑24 enjoys enhanced stability at low speed — ideal for takeoffs, landings, and low-level penetration missions — while swept wings provide reduced drag and higher speed in attack or transit profiles.
The aircraft is powered by two Lyulka AL‑21F‑3A turbojet engines and is characterized by a unique side‑by‑side cockpit configuration, housing both the pilot and the weapons systems officer. This arrangement facilitates communication and coordinated navigation and targeting during complex strike missions.
Other notable systems include advanced navigation and terrain-following radar systems, which — for their era — offered unprecedented capability for low-level flight in all weather, day or night. Its maximum payload capacity is about 8,000 kg of ordnance, carried on nine external hardpoints, encompassing everything from free-fall bombs and rockets to guided missiles.
Operational Evolution: From Soviet Service to Global Use
Initial Deployment and Soviet Era Role
The Su‑24 entered service in 1974, rapidly becoming the backbone of Soviet tactical bombing capabilities. Unlike strategic bombers designed for nuclear strike missions, the Su‑24’s mission was tactical: interdiction, close air support, and battlefield deep-strike operations. Its low-level terrain-masking ability, combined with high-speed ingress and egress, distinguished it from older designs and made it a formidable adversary against NATO air defenses.
During the last decades of the Cold War, the Su‑24 was operated not only by the Soviet Air Force but also by the naval aviation arm, reflecting its multifaceted role in maritime strike, anti-ship warfare, and joint operations with surface forces. Its export variant, the Su‑24MK, was sold to several allied nations, including Algeria, Iran, Iraq, Libya, Syria, and others, expanding its global footprint.
Post‑Cold War Service and Global Users
Following the dissolution of the Soviet Union, many Su‑24s remained in service with successor states, most notably the Russian Federation and Ukraine. Some nations retained aging but capable fleets, while others retired theirs as newer aircraft became available. Notably, Iran acquired a number of Su‑24MK aircraft from Iraq during the 1991 Gulf War when Iraqi jets fled there to avoid destruction; these airframes were later integrated into the Iranian Air Force.
Combat Record Across Continents
Russian and Soviet Engagements
The Su‑24 saw extensive deployment in conflicts such as the Soviet–Afghan War, where its low-level penetration capabilities were tested against both terrain and insurgent air defenses. In more recent years, Russian Aerospace Forces continued to employ the aircraft in Syria and in the full-scale war in Ukraine — though its role has diminished in favor of more advanced platforms like the Sukhoi Su‑34 Fullback, which offers improved avionics, survivability, and multirole flexibility.
In 2025, Russian Su‑24Ms participated in exercises near the Baltic Sea, practicing precision strikes and low-altitude tactics. NATO nations frequently scrambled interceptors when these older bombers operated near airspace boundaries, underscoring their continued strategic signaling role despite their age.
The Russian Northern Fleet also conducted aerial refueling exercises with Su‑24M aircraft in Arctic polar night conditions in late 2025, demonstrating efforts to extend the operational reach of remaining units and to sustain power projection in extreme environments.
Ukraine’s Adaptation and Losses
Ukraine, inheriting a number of Su‑24 aircraft at the dissolution of the Soviet Union, has maintained some of its fleet through to the mid-2020s. Notably, Ukrainian engineers successfully modified their Su‑24s to carry Western long-range precision weapons such as the SCALP‑EG/Storm Shadow cruise missile, dramatically extending the platform’s strike range — a significant achievement that underlines its adaptability and enduring value in modern conflict.
Nevertheless, Ukrainian Su‑24s have also suffered losses. A Ukrainian drone campaign in late 2025 reportedly targeted a Russian Su‑24 in occupied Crimea, damaging or destroying it along with multiple other assets as part of a broader effort to degrade Russian air power in the region.
Conflict in Other Regions
Su‑24s have appeared in conflicts beyond Eastern Europe. In June 2025, a Su‑24M operated by Russian forces in support of Mali’s military crashed into the Niger River under contested circumstances, reflecting the aircraft’s use by private military contractors under Russian direction in African theaters.
The 2026 Iran Conflict and Middle East Engagements
Recent reports in March 2026 indicate that two Iranian Su‑24MK bombers were downed by the Qatar Emiri Air Force, marking a notable engagement in the unfolding Iran-related conflicts in the Gulf region. These strikes reportedly occurred during sortie missions that approached Qatari territorial waters and were shot down by Qatari fighters – an event that signifies the Su‑24’s continuing involvement in high-intensity aerial warfare even decades after its creation.
Modernization, Replacement, and Legacy
Upgrades to the Platform
Over its lifespan, the Su‑24 has undergone successive upgrade programs aimed at enhancing its navigation, targeting, and weapons delivery systems. These include the installation of advanced electro-optical targeting pods, terrain-following radar updates, and integration of precision-guided munitions – improvements that have helped keep the type combat-relevant even into the 21st century.
The emergence of specialized variants – such as the Su‑24MR reconnaissance aircraft and the Su‑24MP electronic warfare platform – illustrates the adaptability of the basic frame to diverse mission requirements.
Successor Aircraft and Phasing Out
Despite these upgrades, Russia and other operators have increasingly shifted toward newer strike aircraft. The Sukhoi Su‑34 Fullback, for example, has become the principal deep-strike platform for the Russian Aerospace Forces, offering modern avionics suites, improved survivability, increased payload, and multirole capability. Russia also continued to deploy other modern combat aircraft in the mid-2020s, including Su‑35S fighters and additional Su‑34s, highlighting a broader modernization of tactical aviation.
Enduring Legacy and Historical Significance
The Su‑24’s half-century of service across multiple geopolitical eras underscores its resilience, adaptability, and the soundness of its original design concept. Though many air forces have retired or are in the process of retiring their Su‑24 fleets, the aircraft persists as an icon of Soviet aerospace engineering and a bridge between Cold War era design and modern tactical aviation needs.
