Ukraine has said it deployed an unmanned vehicle that traveled across land and water and delivered ammunition and supplies to its troops in a technological breakthrough that could boost its frontline efforts.

Ukraine’s defense ministry said the robotic amphibious platform was used for the first time, moving provisions across 25 miles of mixed land and water.

The announcement on Tuesday comes as Ukraine increasingly touts its battlefield technology and its unmanned ground vehicles (UGV).

Ukraine’s Third Army Corps announced earlier this month a world first in which attack ground robots from heavy bomber drones went deep into the Russian rear.

Newsweek has contacted the Ukrainian defense ministry for comment.

What Is Ukraine’s New Amphibious ‘Robot’?

Ukraine’s defense ministry said on Tuesday that its new amphibious platform could easily shift from traveling from land to water within seconds.

This solves the logistics problem on parts of the Ukrainian front where rivers, canals and marshes prove to be obstacles to supplying troops.

“One robot gets more opportunities to perform missions in different terrains,” it added, in a statement according to a translation.

Ukraine’s defense ministry released infrared imagery of the device going over open land and in water.

The vehicle had been developed as part of Ukraine’s state-backed defense-technology innovation cluster Brave 1, which connects developers in Ukraine with the country’s military and government.

It was tested by Ukrainian troops over several months and adapted to battlefield conditions, the statement added.

Unmanned ground vehicles are playing a larger role in Ukraine’s assault tactics against Russia as they carry out tasks once assigned to infantry.

This month, Ukraine’s defense ministry said that the number of missions of ground-based robotic systems had more than tripled since the start of this year.

In August, drones completed more than 25,000 logistics and evacuation tasks on the front line.

Third Army Corps Brigadier General Andrii Biletskyi said this month heavy bomber drones had delivered suicide ground drones more than six miles into Russia’s rear.

Ukrainian media reported that its forces had used air delivery of ground robots before but this was the first time it has been used for kamikaze unmanned ground robotic systems over such a distance.

Biletskyi has been publicizing details of Ukraine’s Operation Vivaldi in the Lyman direction which has thwarted Russian attempts to encircle the “Fortress Belt” of well-defended cities key to the defense of the Donbas region.

He said on Monday his forces had liberated 51 square kilometers of land in the third phase, for a total of 176 square kilometers over Operation Vivaldi’s three announced phases.

Retired Australian Army Major General Mick Ryan wrote on the Futura Doctrina Substack that this dimension of the Ukrainian counteroffensive in which there is the return of offensive maneuver “matters perhaps even more than the amount of Ukrainian territory liberated.”

“This is a large, real-time experiment and proving ground for integration of UGVs into traditional land formations, and the development of new tactical and operational methods to break out of defensive and positional concepts of operation,” Ryan said.

However, the Russian military is continuing to step up its use of jet-powered Geran drones forcing Ukraine to build and field a growing fleet of new high-speed interceptors to plug its air defenses.
