An unmanned Ukrainian sea drone shot down a Russian SU-30 fighter jet near the port of Novorossiysk - home to the Kremlin's Black Sea Fleet. The downing of the £38 million jet was carried out by Group 13 on May 2, a special unit within Ukraine's military intelligence.
The sea drone was reported to be equipped with a R-73 air-to-air missile, which struck the jet in midair. The SU-30 crashed into the sea. Reports suggest that the crew were able to eject from the stricken jet and were later picked up by a civilian cargo ship.
In a statement confirming the plane's shooting down, Ukraine's military intelligence said: "This is the world's first destruction of a combat aircraft by a naval drone."
Ukraine has previously shot down two Russian Mi-8 helicopters using Magura V5 drones on December 31, 2024.
The Sukhoi Su-30 is a twin-engine, two-seat, all-weather, long-range, multirole fighter jet.
It's designed for air superiority, air-to-ground, and air-to-sea operations.
Key characteristics include powerful engines, a large payload capacity, and advanced avionics for air-to-air and air-to-ground combat.
Recently another Sukhoi Su-30SM fighter jet was destroyed in a fire at the Rostov-on-Don Central airfield.
The fire was reportedly caused by sabotage, with Ukraine's intelligence describing it as an act of resistance against "Putinism".
It is estimated that the Russian airforce has around 100 Su-30SM jets, wile the navy has around half this number.
During the course of the war, Putin's military has lost at least 139 fixed-wing aircraft.
A state of emergency was declared in Novorossiysk, after Ukraine launched a massive wave of drone attacks.
Apartments in two multi-story buildings were damaged in the city during the course of the attack.
A video captured the moment one of the high rise buildings was hit, causing fires to break out in several apartments.
