Under the partnership between the UK and Ukraine, closer co-operation in the defence industries will also be sought with third countries as part of efforts to bolster international security.
Britain will also give £500,000 to fund an AI centre of excellence in Kyiv.
In a statement ahead of the meeting, UK Defence Secretary John Healey said it was “increasingly important that we build on Ukrainian expertise and innovation”.
Sir Keir said: “Drones, electronic warfare and rapid battlefield innovation are now central to national and economic security, and that has only been further magnified by the conflict in the Middle East.
“By deepening our defence partnerships, we are strengthening Ukraine’s ability to defend itself from Russia’s brutal, ongoing attacks, while ensuring the UK and our allies are better prepared to meet the threats of the future.”
Wars ebb and flow, and right now Ukraine’s facing a harsh tide. Rising oil prices are fuelling Russia’s war machine, and allies are distracted and divided over the Middle East.
Zelensky is currently on a tour of European capitals to shore up support and keep his conflict at the forefront of allies’ minds.
In his overnight address on Monday, Zelensky said he was working with allies to boost Ukraine’s defences, but the key to peace was more putting more pressure on Russia.
Last week, teams of Ukrainian military experts were sent to Qatar, the United Arab Emirates and Saudi Arabia to help them defend against drones launched from Iran.
Zelensky said Ukraine had “the greatest experience in the world in countering attack drones”. In its fight against Russia, Ukraine has been using cheap, mass-produced interceptor drones to keep defend its skies.
