At the end of last month, Ukraine announced a new set of achievements, and the results were outstanding, shooting down 13 fighters of the Russian Aerospace Forces in 13 days in a row, just one day quite domineering. You must know that in Russian propaganda, the Ukrainian Air Force has been "annihilated" at the beginning of the war, but now it can shoot down Russian fighters one after another.
The 13 fighters include nine Su-34 fighter-bombers, which are not very many, and as of last year only 150 were equipped. If the downing speed of Ukraine is followed, it is estimated that the Russian Su-34 fleet will cease to exist in another half a year, in addition to 2 Su-35 fighters, and 1 A-50 airborne early warning aircraft.
As of Feb. 29.
The Ukrainian MiG-29 has the ability to launch "Hamm" after modification.
I don't know if it was a coincidence or an accident, but recently Singapore's defense minister said when introducing the purchase plan of the F-35A that this aircraft has participated in the Russia-Ukraine conflict and has played a very good role. It is equivalent to that the F-35 has appeared on the Russian-Ukrainian battlefield, and has combat experience with the Russian army, maybe he just wants to prove that the F-35 is indeed very powerful, but everyone knows that the American F-35 has also participated in the war.

According to him, the US F-35 did not directly launch missiles to participate in the operation, but played a reconnaissance and guidance role in the air, such as informing Ukraine of the positioning of the Russian air defense system and providing guidance for the Ukrainian army's missile launch. On the surface, although it did not directly launch the missile, it obviously played a greater role in intelligence sharing, which also explains the heavy losses of the Russian Aerospace Forces.
As the U.S. F-35 has been put into the Russian-Ukrainian battlefield, it identifies and locates the Russian army's surface-to-air missile bases and air defense systems on a daily basis, and then shares this intelligence with NATO countries. This will be a more terrible thing than doing it directly, after all, the blessing of the intelligence system can even turn the tide of the war, which is not difficult to explain why the fighters of the Russian Aerospace Forces have fallen down in advance recently. For example, the A-5 early warning aircraft escorted by fighters far in the rear, and the Il-22 electronic warfare aircraft specializing in electronic warfare did not escape, and in the end, Su-35 and Su-34 fighters also fell down one after another.

On March 2, the NATO Air Force told the Russian army that we were coming, and on the same day, the fighter jets entered Ukraine to launch a strike on Crimea. Two F-16 and one F-35** fighter jets were dispatched to enter Ukrainian airspace from the direction of Romania to simulate a missile attack on Crimea and the Black Sea Fleet. In addition to the exercise of tactical strikes on Crimea, the F-35 also carried out tracking and positioning, including reconnaissance and locking of the position of the Russian air defense radar. The entire exercise lasted 32 minutes, and all the things that could and could not be done were done, and then NATO fighters flew out of Ukrainian airspace, at least from this public exercise, it can be seen that the F-35 has been familiar with the road more than once.
The US F-35 has entered the territory of Ukraine many times, and the Russian military has been slow to respond to this and has not detected it in time, coupled with the fact that the electronic warfare is already lagging behind, and I do not believe that the US F-35 will choose to stab in the back. Therefore, the intelligence information of the air defense system is constantly being reconnoitred and collected, and if this is still a covert operation, the above-mentioned NATO exercise is very high-profile and indicates that they have never stopped. Through reconnaissance by various means, find loopholes in the Russian air defense system, and then share the intelligence with the Ukrainian Air Force, so that their backward fighters can also shoot down advanced models of the Russian Aerospace Forces, and even attack a large number of targets in depth in the Russian rear.

As mentioned earlier, the Ukrainian Air Force has long been "annihilated", and because the Russian Air Force is strong, it can only choose to fight guerrillas, until the air defense network is established after the intervention of Europe and the United States, and at the same time these fighters are modified and upgraded, which has the power to fight a war. Although there are no AWACS aircraft and no electronic warfare aircraft, the old Su-24 and MiG-29 are already the main models, but it is these fighters that can accurately fly along the edge of the Russian radar search, and then launch missiles at the Russian army at the most suitable location.
The Russian army, which already has the advantage of strength, has no power to fight back, and the established air defense network does not seem to work, which can only be said to be due to the intelligence sharing between the United States and NATO, including the F-35** fighter that can approach and accurately locate. It is equivalent to the information positioning and guidance provided by the F-35, the MiG-29 fighter is only responsible for launching missiles, and then can smoothly attack the Su-35 fighter with advanced performance, as well as the A-50 early warning aircraft escorted by the fighter, etc., and the MiG-29 acts as a bomb platform to deceive the Russian army.

Soft power is more terrible than direct action, as more NATO early warning aircraft and F-35** fighters are put into the battlefield in Ukraine, whether it is open or secret support, it can play a role in sharing target information and guiding missile attacks. Moreover, the follow-up F-16 is about to be equipped with the Ukrainian Air Force in batches, and the Mirage 2000 and JAS-39 "Gripen" fighters are also being negotiated.
