Synopsis: Ukraine has received the final shipment of M1A1 Abrams tanks from Australia, bringing its total fleet to 80 units following earlier U.S. donations.
-While the $245 million transfer boosts Kyiv’s armored capabilities, the tanks face severe challenges on a drone-saturated battlefield where nearly 90% of the original U.S.-supplied fleet has already been lost or damaged.
-Despite U.S. officials privately warning that the gas-guzzling tanks would be a logistical nightmare to sustain, the delivery completes a major Western aid pledge that began in 2023.
80 Tanks Delivered: Ukraine Finally Receives Last Shipment of M1A1 Abrams from Australia
Ukraine has now taken delivery of the last of 80 M1A1 Abrams main battle tanks promised by Western allies, finally completing a heavy armor transfer pledge that began in 2023.
The Australian Defence Force confirmed on December 19, 2025, that the 49 remaining promised M1A1 Abrams tanks have been delivered to Ukrainian forces after a months-long transit from Australia to Poland and onward into Ukraine.
The donation has been valued at roughly $245 million and forms part of roughly $1.7 billion in total military and security assistance to Kyiv from Canberra since Russia’s full-scale invasion, under what Australia calls “Operation Kudu.”

“It is a huge undertaking to bring a 60-tonne tank half way across the world and make sure that when we give it to our Ukrainian friends, it is ready to use,” Commander of Operation Kudu – Europe, Colonel James Smith, said in a press release issued by the Australian government.
The latest deliveries complete a full effort that was preceded by the delivery of 31 Abrams tanks supplied by the United States in 2023, bringing Ukraine’s total received Abrams count to 80.
The Politics Behind the Abrams Decision
The decision to provide Abrams tanks to Ukraine was made in January 2023 when the Biden administration approved the transfer of U.S.-made M1A1 Abrams tanks as part of a larger security assistance package.
That decision was aimed not just at bolstering Ukraine’s armored capability but also at strengthening the alliance supporting Ukraine and synchronizing the delivery of heavy armor from Western partners – including Germany’s pledges of Leopard 2 tanks.
Since testing at U.S. Army Cold Regions Test Center, the Department of Defense’s lone extreme cold natural environment testing facility, began in January 2020, the M1A2 System Enhancement Package version 3 main battle tank was driven more than 2,000 miles in rugged conditions across three seasons of sub-Arctic weather, fired hundreds of rounds for accuracy in extreme cold, and underwent testing of its auxiliary power unit.
Though the platform was extensively tested at U.S. Army Yuma Test Center prior to being put through its paces in Alaska, the sub-zero temperatures brought forth glitches that would have been unimaginable in the desert.
And although the Abrams tank is widely considered to be one of the most capable main battle tanks in the world, its deployment in Ukraine has not been without controversy.
Visual open-source analyses have indicated that Ukrainian forces have already lost a significant number of U.S.-supplied Abrams tanks in combat, including vehicles destroyed, abandoned, or captured by Russian forces.
As of mid-2025, approximately 87 percent of Ukraine’s fleet of U.S.-supplied Abrams tanks have been visually confirmed as destroyed, damaged, abandoned, or captured.
What’s Going Wrong?
Beyond attrition from battlefield losses, the M1A1 Abrams faces a dilemma regarding general sustainment and operations.
Ukrainian units operating the Abrams have faced a battlefield dominated by new technology – from drones and precision munitions to anti-armor weapons that efficiently exploit vulnerable top armor on the Abrams and the logistical vulnerabilities that come with operating the platform.

While those vulnerabilities were harder to exploit in the early days of the war, the battlefield has since evolved into a futuristic warzone where an increasing number of drones on both sides are assuming greater responsibility in combat.
The problem is so bad that reports indicate Ukraine has fitted some Abrams tanks with improvised additional armor and anti-drone cages to improve their resilience.
Still, those adaptations are ad hoc responses to an evolving threat and not a real solution to the problem.
The complexities of sustaining heavy Western armor like this in a protracted war against an adversary like Russia extend well beyond attrition, too.
The Abrams platform is highly demanding, requiring specialized maintenance, spare parts, complex fuel logistics, and trained crews to keep them in good working order – all of which pose significant challenges for Ukrainian forces that are already stretched.
In short, the Abrams are not as helpful as the Biden administration had hoped in 2023.
U.S. Frustration Behind the Scenes on M1A1 Abrams Tank Call
Although the Abrams transfers have been successful and proceeded with public support from Washington, some U.S. officials were reluctant about the idea from early on.
According to reports, American officials advised Australia in 2024 to reconsider or delay its transfer of Abrams tanks to Ukraine, warning that the vehicles would impose substantial sustainment burdens once they finally reached the battlefield.
Speaking to ABC, one U.S. official described efforts to convince Australia to reverse course.
“Last year, even before Donald Trump returned as president, we warned the Australians that sending these Abrams tanks would be complicated, and once they finally get to the battlefield the Ukrainians will find them difficult to sustain,” the source said.
The concerns were expressed even as Washington ultimately granted the necessary export approvals under the U.S. International Traffic in Arms Regulations (ITAR), which govern the transfer of U.S.-origin defense equipment.
So, for Kyiv, the arrival of the last Abrams is good news and bad. It represents a boost in armored capability, but also poses new challenges for forces already struggling to protect them on the battlefield.
