Looks like we have our first F-16 shot down by Russia in Ukraine now. Both Russian and Ukrainian sources (including Ukrainian President Zelenskyy) have confirmed that an F-16 was lost in combat.
Today, Captain Pavlo Ivanov was tragically killed during an F-16 combat mission. The guy was only 26. My condolences to his family and to all of Pavlo’s brothers-in-arms.
As I've already discussed, the early model F-16s Ukraine got are roughly equivalent to their MiG-29s in capability, only being superior in electronic countermeasures (ECM) and native support for American munitions. These early 4th generation aircraft aren't a match for Russian 4.5 generation fighters in a straight fight.
The Ukrainian F-16s have also been relying exclusively on this ECM (provided by the external AN/ALQ-131 external pod) and terrain masking (flying low close to the ground) to suppress Russian Ground Based Air Defense (GBAD), and flying with no anti radiation missiles for suppressing these defences. While a successful tactic up until now, it's highly risky. If the ECM fails or is bypassed, the pilot has no way to suppress any GBAD firing at them. If you look at the Russian air campaign in Ukraine, the escort fighters or strike fighters carrying out the strikes themselves (in Su-35s and Su-34s) are always carrying at least one Kh-31P anti radiation missile. In the US Navy air campaign against Yemen, the EA-18G Growlers are flying escort missions with at least two AGM-88E anti radiation missiles, along with highly advanced ECM that is much more sophisticated than the AN/ALQ-131.
I'm not a fighter pilot, but if I was and you told me I had to fly a strike mission in a block 20 F-16 for Ukraine in Sumy, where our high level friendly Ukrainian GBAD (in an S-300V battery) has been destroyed, and I'm going up against the best of the best Russian GBAD and combat air patrols in S-400 GBAD and Su-35 fighter jets, and I'll have to fly a nap of the earth/terrain masking flight path to the launch point for my bombs, with only an ECM pod and no anti radiation missiles to suppress the Russian GBAD, and that there would be no allied Ukrainian aircraft higher up with anti radiation missiles to act as an escort, and all I have to try fend off the Russian Su-35s is the crappy radar on the block 20 F-16, along with 2 AIM-120 and AIM-9 air to air missiles, I would not fly the mission.
The Russian A-50s have started flying a few weeks ago, for the first time in over a year. So AWACS aircraft are back. They are expensive and hard to make because they require a lot of modern sophisticated electronics to work on the modern battlefield. You can't build an AWACS with 40 year old sensor equivalents and expect it to work against modern electronic countermeasures. Russia is working on building A-100 AWACS aircraft, with testing ongoing. The current Ukraine war and sanctions have hurt the modernisation programs (Su-57, Su-75, A-100), with focus moved to more pressing issues like artillery and armour production. Only the Su-57 appears to have survived.
