Having already reshaped the battlefield by doing work once reserved for long-range missiles, field artillery and human intelligence, drones are now fighting Russian drones - a boon for Ukraine's dwindling stock of air defence missile systems.

Ukraine’s Security Service said its drones destroyed one jet and damaged four at Saki military airfield overnight, aiming to weaken Russia’s war capability in the occupied Crimea and on the Black Sea.

Russian forces launched a nighttime attack on Ukraine in the early hours of August 5 using kamikaze drones and a ballistic missile. Ukraine's Air Force reports that most of the enemy targets were intercepted.
