Analysis of information sources in references of the Wikipedia article "List of aircraft losses during the Russo-Ukrainian War" in English language version.
Commercial satellite imagery from Feb. 27 appears to show a couple of wrecked Su-24s at Lutsk following a Russian strike
There however is evidence the Ukrainians have lost at least one Su-24. On March 30, a video circulated on social media apparently depicting a Ukrainian bomber trailing smoke over Rivne in western Ukraine, purportedly after a Russian fighter intercepted it. At least one of those claimed kills appears to be valid.
In retaliation, the Russians have managed to shoot down just two TB-2s that analysts have verified. The most recent documentation of a wrecked TB-2 circulated on social media beginning Wednesday. A day prior, photos appeared online of MAM missiles in Russian hands, possibly from the same destroyed TB-2.
At the same time, there's photographic evidence that the Ukrainians have shot down at least one of Russia's killer drones. Yes, the Russians have shot down at least three TB-2s, but the Ukrainians can afford to lose more drones.
While supplying aircraft would address the immediate problem of replacing attrition losses, Ukraine's main airbases have been subjected to attack, with at least six MiG-29s destroyed on the ground at Ivano-Frankivsk Airport in the southwest of the country.
He adds that there has been official confirmation of at least one Ukrainian Air Force Su-27 Flanker being destroyed during the first wave of attacks on Ozerne Air Base in central Ukraine.
Oleg Chervov was buried at the memorial to military pilots on the Alley of Heroes of the Komintern cemetery in Voronezh...In the upper part of the monument to Major Filipov, there is an Su-25 attack aircraft directed into the sky – Oleg Chervov also flew on the same plane.
As for other planes that remained in Hostomel, the pilot said that the An-74 and An-26 were destroyed. But An-22 and An-124 "Ruslan" are damaged. Regarding their recovery, the pilot said:'I believe that Ruslan will be restored, An-28 will be restored. The An-22 may also be restored, but it has been severely damaged.'
Certain is only that the Ukrainians lost another Su-25. 'Blue 31' was shot down yesterday afternoon
(elevated) terrain and vegetation in the background. This photo is probably showing the wreckage of the Mi-24 shot down on 5 Mar, in the Bashtanka area.
'All deliveries were successful,' Budanov said. But on the 5th and 7th missions, two helicopters were shot down. A third helicopter coming to the rescue on one of those was also destroyed, Budanov said.
Russian air defense systems shot down a Ukrainian Tu-141 Strizh drone over Crimea, allegedly launched from Odesa.
Earlier today, the Ukrainian Ministry of Defense published a photo of the wreckage of a Russian Aerospace Forces Su-25 Frogfoot ground-attack aircraft, a type that has apparently already seen extensive use with both sides during the conflict. Unconfirmed reports suggest that a Russian Mi-8 helicopter that may have arrived on the scene of the crash to assist was in turn brought down by Ukrainian air defenses. At this stage, this is only speculation, however.
...footage has also emerged showing the apparent demise of a Russian Aerospace Forces Su-34 Fullback strike aircraft. Although the location and date of the incident remain unconfirmed, the aircraft is clearly seen in a flat spin, in which an aircraft plummets from the sky in rotational motion with no forward speed. A flat spin is sometimes impossible to recover from, which was the case here, although it's unclear whether the jet was hit by an air defense system or suffered some other kind of failure.
Footage showed an Su-34 trailing fire from its right engine over the frontline in Kharkiv Oblast, with a later clip showing a fireball and crash site in the area. Later videos showed an Su-30SM crashing after being hit by a missile, with two parachutes seen descending nearby.
Additional satellite imagery that has been published since yesterday's blasts at Engels and Dyagilevo suggests that the drone strike on the first of these bases may also have resulted in at least one aircraft being damaged. Imagery shows a Tu-95MS bomber that appears to have suffered a fire, with one view showing a number of fire trucks and foam residue around the aircraft. This level of detail had not been available in the satellite imagery that was previously available. If the Tu-95MS was indeed damaged, that would add to the confirmed damage inflicted on a Tu-22M3 at Dyagilevo.
A formation of Russian helicopters comes under ground fire, resulting in two of the helicopters — apparently Mi-8 or Mi-24/35 types — impacting the water. While one of these rotorcraft is brought down, the other appears to make a remarkable recovery and continues flying.
There are destroyed helicopters visible elsewhere around the airfield, as can be seen below on the facility's northwest landing pads area.However, none of them appears to be actively burning and some of these losses are the result of prior attacks. The Planet Labs satellite image that The War Zone obtained also underscores how much of a target-rich environment the base is at present, both in terms of aircraft and ground vehicles, some of which may have been left behind by withdrawing Ukrainian forces
Images of an 'obsolete' Ukrainian Tu-143 unmanned scout drone that was shot out of the sky by Russian forces over Kharkiv were widely shared.
