With All Union now on a little cooldown, I figured I’d share my exposition/notes about the Soviet-Romanian air war:
Overall course of the war: Starting on September 8, 1998, the Sovereign Union invaded Romania with two fronts (army groups). The northern Dniester Front was arguably the most advanced and powerful fighting force in history at that time. That combined with good terrain made it sweep south in close to nine days. The southern Danube Front had a more difficult task in the form of more fortifications,more cohesive defense, the daunting task of crossing a massive river opposed, and the bulk of it consisting of forcibly mobilized Bulgarians. Still, after the same nine days they had encircled Bucharest and linked up with the Dniester Front. For the rest of the month they prepared to storm the city, continued bombardment, and tried to push for a surrender that eventually came.
In the end, the USSR lost around 3,500 soldiers and the Bulgarians and other minor allies around 7,000. Romanian casualties are almost literally uncountable with at least 70,000 being essentially confirmed and with estimates as high as 120,000 KIA.
Now for the air:
The USSR’s air force was a curious mixture of everything from the hyper-advanced Su-37 Fermion fighter to dozens of ancient Il-28s. In general, METT-TC was used to allocate things, with older planes doing area strikes with smother/splash damage weapons in the daytime and newer ones using PGMs at night whenever possible. While not perfect, it was extremely devastating.
Romania:
The initial fire strike took out around five hundred Romanian aircraft on the ground, over 80% of its total. This caused a lot of panic in the USAF after the war. A few planes made it through, most notably in the defeat of a Danube Front forward detachment at Alexandria very early on. Otherwise Romanian aircraft were limited to tiny nuisance strikes and suffered very heavy losses while doing so, though surprisingly few to the vaunted SAMs. (Total air superiority+tons of friendly Soviet aircraft = a very short ROE leash and lots of fighter opportunities).
