US Military Intensifies Cuba Blockade with Recent Ship Seizures, Deepening Island's Fuel Crisis

US Military Escalates Maritime Interdictions Against Cuba-Bound Vessels

The United States military has significantly intensified its efforts to disrupt Cuba's access to fuel, seizing multiple oil tankers in recent months. These interdictions are part of what the Trump administration has termed a 'naval quarantine' or 'energy blockade' against the island nation, contributing to a severe and rapidly deepening fuel crisis in Cuba. The actions follow a broader US military buildup in the Caribbean, known as Operation Southern Spear, which began in August 2025, initially focused on combating drug trafficking but later expanding to include the interdiction of oil tankers.

Key Seizures and Interdictions Highlight Intensified Pressure

The latest phase of this pressure campaign gained momentum following the US capture of Venezuelan President Nicolás Maduro on January 3, 2026. Since then, several vessels suspected of carrying oil to Cuba have been targeted:

• On February 15, 2026, the US Armed Forces intercepted and boarded the Verónica III, a Very Large Crude Carrier (VLCC), in the Indian Ocean. The vessel, carrying approximately 1.9 million barrels of crude oil and fuel oil from Venezuela, had been tracked from the Caribbean and was operating in defiance of President Trump's declared quarantine.
• Just days prior, on February 9, 2026, the Aquila II, a Panamanian-flagged Suezmax tanker, was seized in a similar operation in the Indian Ocean. This vessel was under US sanctions related to illicit Russian oil and was also deemed to be violating the quarantine.
• Earlier in December 2025, the tanker Skipper, carrying 1.8 million barrels of crude, was captured while en route to Cuba.
• The chemical/product tanker Ocean Mariner, which had delivered 86,000 barrels of fuel to Cuba from Mexico on January 9, 2026—reportedly Cuba's last oil shipment—altered its course away from the island on February 13, 2026, after the apparent presence of a US Coast Guard cutter in the Windward Passage.

These actions are underpinned by an executive order signed by President Trump on January 29, 2026, which authorizes the imposition of tariffs on any country supplying oil to Cuba.

Cuba Grapples with Unprecedented Fuel Shortages and Humanitarian Concerns

The intensified US pressure has plunged Cuba into its most severe energy crisis since the Cuban Missile Crisis, with a New York Times analysis describing it as the 'first effective blockade' since that period. The island is experiencing widespread and prolonged blackouts, lasting up to 20 hours daily in some areas. Fuel rationing has become commonplace, severely impacting daily life, including public transportation, hospitals, schools, and food production. Satellite imagery has revealed a 50% decline in nighttime light levels in cities like Santiago de Cuba and Holguín. The scarcity of jet fuel has led to significant disruptions, with Cuban aviation officials warning airlines of unavailability at multiple airports, including José Martí International Airport in Havana, and Air Canada suspending flights to the island.

International Condemnation and US Objectives

The US administration has openly stated its motivation for these actions, aiming for 'regime change' in Cuba by the end of 2026. However, these measures have drawn significant international criticism. UN human rights experts have condemned the US executive order, calling it a 'serious violation of international law' and a 'grave threat to a democratic and equitable international order,' warning of potential humanitarian collapse. Russia has also condemned the US actions, pledging to continue its oil shipments to Cuba. Mexico, which had previously supplied oil to Cuba, halted shipments under US pressure but later sent humanitarian aid to the island. In response to the escalating tensions, Cuban authorities have declared a 'state of preparation for war.'
