The way forward in Ukraine absolutely needs to include a functional defensive air arm. The Ukraine needs to keep Russian air (including helicopters) off their troops. It is also probably essential that Ukraine possess enough offensive tac air to make holes in the Russian defensive fortifications and concentrations. At present, Ukraine is using artillery to accomplish this destruction. That is a "classical" way of accomplishing the task. Unfortunately it is by nature a very resource intensive process that is also relatively "slow". Concentrating enough artillery requires bringing many guns into a relatively small area and keeping them there long enough to accomplish their task. During this time these guns are pretty much fixed targets that the Russians can attack. Very large logistic efforts must be made to deliver the shells necessary to do the requisite damage.
Equally significantly, the Russians can detect the beginnings of such an artillery concentration and therefore know where Ukraine intends to attack. This allows the Russians to reinforce their defenses and to build a second line of defenses if necessary. For this reasons, both Russia and Ukraine often use multiple limited objective attacks to hopefully find "soft spots" where they can concentrate their forces. Unfortunately this usually doesn't work and it becomes a slugfest. Even when one side prevails, there are limited gains because the defenders simply fall back to the second line of defense that the slow rate of advance has allowed them to create.
The US discovered the obvious in WW II, namely that it is possible to "concentrate" very large tactical air forces at any given point in the enemy defenses at any time. These forces can deliver the effect of a sustained artillery barrage in a matter of hours. If the enemy cannot deny the airspace to the US forces, they have no chance. While this approach does have its problems (advancing tanks across moonscapes isn't easy), it can work. The enemy has no time to build a second line of defense because he doesn't have days of advance warning. This can create the fluid battlefield that the US (and NATO) want. Ukraine can't do this at present. They have to do it the "old fashioned way" and that is expensive in lives.
My concern here is that (as usual) we are late to the game here in creating a Ukrainian air capability. The article talks about a compressed training period of less than six months, more like four. If we had acted in the summer of 2022 to start training Ukrainian airmen (pilots and support personnel) it would have been reasonable to expect Ukraine to have been able to defend their airspace and cover their troops in summer of 2023. It would have been a real surprise if Ukraine could have developed a "good" tac air capability in a year. It isn't just learning to fly the planes. You need to understand the weapons systems and know as second nature how to employ them. Further, the upper echelons need to learn to plan the missions and arrange for all the details (fuel, weapons, de-confliction, EW support, maintenance standowns, etc.). This isn't something Warsaw pact units did much of, so their upper echelons have no experience doing it. It ain't easy, and the USAF has screwed it up often enough to prove that.
It appears to me that Ukraine is relying on the fact that 1) their airmen are very much above average (may be true, but dubious) and will "learn it all real fast", and 2) the Russians are somewhat inept in the air and Ukraine can compensate for a lack of training and a lack of numbers with superior morale and dedication. They may be right about the Russians not being stellar in the air, but Ukraine also has to understand the number of F-16s they will have is limited. For them, a 3:1 advantage in kill ratio is a loser. They need to be better than that, and IMO doing so in 4 months of training/experience isn't even vaguely possible. It absolutely isn't possible in a European winter where the idea of flying every day is impossible. Simulators are nice, but it isn't the "real thing". Ukraine can't afford a "failure" here, as it is a big logistical and resource intensive effort to integrate a new aircraft and a new set of tactics into your air force. It is NOTHING like learning to use a Patriot, which is mostly automatic anyway.
