Ukrainian Air Force Su-27 fighter jet was shot down over Kiev: In the early morning of the 25th, a fighter was shot down over Kiev, initially all parties thought it was a Russian fighter, but photos of the wreckage of the airframe after dawn appeared, painting the blue Ukrainian Air Force. The Ukrainian military also admitted that it was its own Su-27 fighter that was shot down that morning, but did not say whether it was shot down by the Russian army or mistakenly hit by its own anti-aircraft weapons. In the early 1990s, the Ukrainian Air Force inherited about 66 to 70 Su-27 fighters from the Soviet Union, including the Su-27S, Su-27P and two-seat Su-27UB, but by 2014 only 19 were available, mainly equipped with the 831st Tactical Aviation Brigade. At the same time, Ukraine also upgraded these Su-27s, which were named Su-27UB1M, Su-27S1M and Su-27P1M. However, the upgraded technical level is still lagging behind the Russian Su-30SM and Su-35 fighters, while the Ukrainian army does not have active medium-range ammunition, only semi-active radar-guided R-27ER and infrared-guided R-27ET two medium-range ammunition, it is indeed difficult to compete with Russian fighters.
