Italy will send a second SAMP/T air defence system to Ukraine - the only European-made system that can intercept ballistic missiles.
Also known as MAMBA, it is a Franco-Italian battery that can track dozens of targets and intercept 10 at once.
Rome and Paris jointly delivered the first system in 2023, but Ukraine has repeatedly called on partners to provide more help with air defence as it faces an increasing barrage of Russian attacks on cities and energy infrastructure.
Italy has approved eight support packages to Ukraine since the invasion began.
Its foreign minister said the SAMP/T will be part of a ninth package under preparation, but did not give a time frame for delivery.
All shipments have so far been covered by official secrecy and the government has never made public the exact list of weapons it has sent to Ukraine.
