The biggest battlefield development is around Novomykhailivka, a key Ukrainian stronghold nearby Marinka. Russian forces have advanced to the very edge of the important town, but they have taken heavy losses. On just a single road, Russia lost at least ten pieces of armored equipment. Russia is still making steady progress towards the town however, and is likely to breach its administrative boundaries within a few days at their current pace.
Ukraine managed to knock down a trio of Russian Su-34s, all of which were attempting to bomb Krynky. It is believed that Ukraine managed to move one of their quite rare Patriot batteries into position without Russia knowing, achieving tactical surprise and consequently destroying the three Russian planes. It is similar to a previous event, in which a. Ukrainian Patriot battery knocked down two Russian warplanes and three helicopters in short order over Bryansk oblast, Russia. As for the loss of the Su-34s, they are modern warplanes and the lower bound on the number that Russia has produced is 125. Given the previous loss of 22 through various means (hostile action and various mishaps), this means that up to a fifth of Russia's Su-34 fleet has now been destroyed.
In other aviation news, Russian milblogger Rybar has made the so far entirely unverified claim that F-16s are already in Ukraine, based in the western part of the country. This would be months ahead of schedule, and in a recent interview, a recently retired American general even suggested that their delivery might be delayed further until the summer. The timing of the rumor that Ukraine has F-16s id interesting not only because it was overall an embarrassing day for Russian air power, but also because the Netherlands today finalized the number of F-16s that they are planning on giving to Ukraine; a total of eighteenth, plus a handful of training craft.
Russia's political and economic grip over the breakaway Moldovan region of Transnistria is softening. Transnistria, as part of the new border control policies implemented between Ukraine and Moldova, is handing over control of two border checkpoints to the central Moldovan authorities. Transnistria also stated that they are seeking negotiations with Moldova in the "1+1 format"; basically, direct negotiations without Russian, Ukrainian, or EU input unlike in the past. Transnistria and Moldova have had some sense of a relationship for a while, but this is one of the most notable shifts Transnistria has made away from Russia, and it was combined with a minor act of integration with Moldova. Transnistria still hosts around 1500 Russian soldiers who are trapped by Russia's invasion of Ukraine.
