The British defence secretary is in Kyiv today for a meeting with Volodymyr Zelenskyy - and has announced another tranche of UK support.
It will provide a further £125m of investment, which will fund more than 10,000 drones.
These include first-person view (FPV) drones, 1,000 one-way attack drones, and surveillance and maritime drones.
The move follows an announcement last month that the UK will co-lead an international coalition to supply drones to Ukraine.
Defence Secretary Grant Shapps said: "I am ramping up our commitment to arm Ukraine with cutting-edge new drones coming directly from the UK's world-leading defence industries – straight from the factory floor to the frontline.
"I encourage international partners to join the UK in this effort.
"Ukraine's Armed Forces are using UK donated weapons to unprecedented effect, to help lay waste to nearly 30% of Russia's Black Sea Fleet."
The further support takes the UK's overall funding commitment for drones for Ukraine to £325m.
