The UK will send hundreds of kamikaze devices to Ukraine to support Kyiv on the battlefield.

As The Telegraph reports, the kamikaze drones have a range of more than 125 miles – more than twice as far as the highly successfully HIMARs – and complement the long-range Storm Shadow missiles the UK donated to Ukraine last week.

Defence sources conceded that the drones were "one-way," adding that they had a "primary goal to carry munitions."

"They have been rapidly developed and adapted at significantly lower costs than others. They have a comparable effect to an artillery shell," the source claims.

It adds that the secrecy was because of commercial confidence as the drones were still going through the later stages of procurement, before adding: "They will be delivered in the coming months."

Earlier this year QinetiQ, the Hampshire-based defence technology company, worked with the Ministry of Defence on a drone programme to
"provide recommendations for uncrewed aircraft systems that could be deployed readily by the Ukrainian military," The Telegraph writes.

According to QinetiQ, one of the test projects included a 3D-printed delta-wing "suicide" drone. There was no indication that this was the weapon procured for Ukraine.

In February, Sunak pledged that the UK would supply Kyiv with longer-range capabilities that would "disrupt Russia's ability to continually target Ukraine's civilian and critical national infrastructure and help relieve pressure on Ukraine’s front lines."

On Monday, Ukrainian President Volodymyr Zelenskyy visits the UK (Ukr). The British government announced hundreds of long-range strike drones and anti-aircraft defence missiles to Ukraine.
