The US has said it will give Ukraine Scan Eagle surveillance drones, mine-resistant vehicles, anti-armour rounds and howitzer weapons to help regain territory and mount a counter-offensive against Russian invaders.

A senior defence official told reporters that a new 775 million dollars aid package will include 15 Scan Eagles, 40 mine-resistant, ambush-protected vehicles known as Mraps with mine-clearing rollers, and 2,000 anti-armour rounds that can help Ukraine troops move forward in the south and east, where Russian forces have placed mines.

The official said the US is looking to help shape and arm the Ukrainian force of the future as the war drags on.

This latest aid comes as Russia’s war on Ukraine is about to reach the six-month mark. It brings the total US military aid to Ukraine to about 10.6 billion dollars since the beginning of the Biden administration.

It is the 19th time the Pentagon has provided equipment from Defence Department stocks to Ukraine since August 2021.

The US has provided howitzer ammunition in the past, but this is the first time it will send 16 of the weapon systems. The aid package also includes 1,500 anti-tank missiles, 1,000 javelin missiles and an undisclosed number of high-speed, anti-radiation or Harm missiles that target radar systems.

The Ukrainian forces have been successfully using various precision artillery systems to try and hold off Russian forces and take back territory Moscow has gained.

For much of the last four months of the war, Russia has concentrated on capturing the Donbas region of eastern Ukraine, where pro-Moscow separatists have controlled some territory as self-proclaimed republics for eight years.

Russian forces have made some incremental gains in the east, but they have also been put on the defensive in other regions, as Ukraine ratchets up its attacks in Ukraine’s Black Sea peninsula of Crimea.

The Russian-occupied territory was seized by Moscow in 2014. Nine Russian warplanes were reported destroyed last week at an airbase on Crimea in strikes that highlighted the Ukrainians’ capacity to strike deep behind enemy lines.

Russian leaders have warned that striking facilities in Crimea marks an escalation in the conflict fuelled by the US and Nato allies and threatens to pull America deeper into the war.

One Western official said on Friday that the war is at a “near operational standstill”, with neither side able to launch major offensives.

The official, who spoke on condition of anonymity to discuss military assessments, said the whole tempo of the campaign has slowed, partly because both sides recognize that “this is a marathon not a sprint and that expenditure rates and conserving their munitions is important”.

But the US and Western officials both said that Ukraine has been able to launch successful attacks deep behind Russian battle lines, which is eroding logistics support and command and control of Moscow’s forces, and harming their morale.

The US official said that while Ukrainian troops have not been able to retake a lot of territory, they have been able to significantly weaken Russian positions in a number of places.

Efforts to tamp down the fighting have also continued. On Thursday, Turkey’s leader and the UN chief met in western Ukraine with Ukrainian President Volodymyr Zelensky.

They discussed a range of issues including prisoner exchanges and an effort to get UN atomic energy experts to visit the Zaporizhzhia nuclear power plant in southern Ukraine.

The facility has been controlled by Russian forces since shortly after the invasion began on February 24 and has been the target of a number of explosions.

Kyiv and Moscow accuse each other of shelling the plant, stoking international fears of a catastrophe on the continent.

Turkish President Recep Tayyip Erdogan said he would follow up with Russian President Vladimir Putin, given that most of the matters discussed would require the Kremlin’s agreement.
