Recent Activities of a Russian Heavy Cargo Aircraft
GRAZ, Austria — A substantial Russian cargo aircraft, known to have previously transported air defense machinery to Venezuela, was spotted landing at a military base close to Havana, Cuba on Sunday evening, according to flight records reviewed by Defense News.
The aircraft, an Ilyushin Il-76 operated by Aviacon Zitotrans, a carrier associated with the Russian government, had an eventful journey to Cuba with layovers in the Dominican Republic, Mauritania, and Algeria, following its departure from St. Petersburg via Sochi, Russia in late January. The plane touched down at San Antonio de los Baños Air Base, located roughly 50 kilometers south of Havana.
Background and Recent Developments
The same aircraft, bearing the registration RA-78765, had previously flown to Venezuela, Nicaragua, and Cuba in late October 2025 during a period of escalating tensions between Caracas and Washington. Following the U.S. military’s intervention in Venezuela on January 3, Cuba has been increasingly targeted by U.S. policies. The situation intensified on January 29 when U.S. President Donald Trump declared Cuba a “national emergency” through an executive order and imposed tariffs on countries providing oil to Cuba, unless Havana complies with U.S. national security and foreign policy demands.
The Il-76 is capable of carrying up to 50 tons of cargo or as many as 200 passengers. This type of aircraft has been used by Russia in the past for transporting small arms, military supplies, and even mercenaries. Aviacon Zitotrans is notorious for its involvement in transporting military cargo and has faced sanctions from several nations, including the U.S., Canada, and Ukraine, due to its role in facilitating Russia’s military engagements.
In January 2023, the U.S. Treasury Department announced sanctions against Aviacon Zitotrans, citing its transportation of military equipment such as rockets, warheads, and helicopter parts worldwide. The company has also been active in shipping defense materials to Venezuela, Africa, and other regions, as well as exporting Russian-made weapons globally on behalf of Rosoboronexport, a state-owned entity.
Uncertainty Over Current Cargo
It remains uncertain what specific cargo the Il-76 is carrying on its current mission. During its previous trip to Venezuela before the U.S. strikes, the aircraft delivered Pantsir-S1 short-range and Buk-M2E medium-range air defense systems to Caracas, as noted by Russian lawmaker Alexei Zhuravlev and state-owned Russian media. The size and weight of these systems suggest that the Buk system, in particular, would need to be dismantled due to its height.
The current flight of the Il-76 mirrors its earlier mission to Venezuela in terms of the route, including stops in northern Africa, amid growing geopolitical tensions related to a Russian-aligned country in Latin America.
Despite the deployment of Russian-made air defenses in Venezuela, they were ineffective against the U.S. operation that led to the capture of President Nicolás Maduro, a failure that experts have attributed to human error, inadequate preparation, and the overwhelming capabilities of the U.S. military.
In March 2025, Russia and Cuba entered into a formal military cooperation agreement which was ratified and signed, setting the groundwork for joint military operations, training exercises, the exchange of military specialists, consultations, and the provisioning of military equipment.
