This fall has been grim for Ukraine. According to our assessment, between 1 September and 30 November, the Russians captured over 1600 km2 in Ukraine, and retook roughly 500 km2 in Kursk. The rate of advance accelerated every month, despite the Russians suffering heavy losses. 1/ Image
Already at the end of the summer, the situation seemed to be developing in a worrying direction. Especially in August, the Russian gains were relatively large, and it did not seem like the Ukrainian offensive in Kursk would significantly slow down the Russians. 2/
During the fall, while making progress in Ukraine, Russia also conducted several counterattacks in Kursk. Ukraine lost the western flank of the salient, while also losing positions in the east. Between September and November, Ukraine didn’t advance significantly in the area. 3/ Image
Main focus of the Russian offensive this fall has been the area of Pokrovsk and Kurakhove. In November, after the loss of Vuhledar, Russians also advanced quickly to Velyka Novosilka. Currently, most of the changes on the frontline are happening on a 140 km section. 4/
Russians are pressuring elsewhere too, but have not gained much in the big picture. Ukrainians held the Toretsk-Chasiv Yar-Siversk direction well, denying Russians of any greater progress in northern Donetsk. The front in Zaporizhzhia didn’t see much change during this fall. 5/ Image
In Kupiansk, the Russians managed to advance to the Oskil river, cutting the Ukrainian presence there in half. However, this can be considered a secondary front without very significant opportunities for the Russians, regardless of whether they are on the river or not. 6/ Image
What can we expect from the rest of the year? Based on the current trends, the Russians can likely continue their offensive in the Pokrovsk-Velyka Novosilka direction. It can be expected that additional 500-700 km2 of Ukrainian land will be occupied. 7/
Russia will likely try to continue advancing in Kursk too, but concentrating very heavy forces there wouldn’t be the best usage of their troops. However, the same applies to Ukraine. Reserves would be needed elsewhere, as the eastern front has had constant setbacks for months. 8/
I’ve been posting a bit less recently, as I’ve been very busy with work. Various articles, reports, lectures, presentations, interviews, TV appearances, a podcast series and my upcoming non-fiction book military history have taken most of my time. 9/
However, we at @Black_BirdGroup still follow the situation closely. You can also find me and us from the other place with bluer skies, if that’s your preferred platform nowadays.10/10

On June 1, Ukraine conducted a successful operation targeting Russian strategic bombers and other aircraft.

Our battle damage assessment can confirm the following losses: 12 destroyed and 3 damaged aircraft, of which 14 are strategic bombers and 1 is a transport aircraft. 1/ Image
From videos and satellite images, 23 distinct aircraft were identified in total as potentially targeted. The condition of 4 aircraft seen in videos remains unclear. Available evidence doesn’t allow for assessing potential damage or whether nearby drones even detonated. 2/ Image
The highest possible number for total losses is 19, if all aircraft in unknown condition are actually damaged. However, this can’t be confirmed at the moment.

In 4 cases, it appears the drones likely missed, did not explode or cause visible damage for other reasons. 3/

Ukraine has struck multiple strategic bombers in Olenya, Murmansk oblast, 1800 km from Ukraine. This is one of the most successful drone strikes against against Russian air bases in the entire war. The extent of the damage is yet unclear, but I can already say it's significant. 1/
Russia had transferred the valuable planes to Olenya to avoid the exact scenario we're seeing on the videos and photos coming from the area. Bombers operating from the field have repeatedly struck Ukraine with cruise missiles. 2/ Image
These are major and expensive losses for Russia that can't be replaced quickly.

Additionally, the air base in Belaya, roughly 4300 km from Ukraine, has been hit. Also Dyagilevo and Ivanovo air bases are burning. This is a very, very successful day for Ukraine. 3/

During April and May, the Russians formed a dangerous salient against the Ukrainian defenses between Kostiantynivka and Pokrovsk.

The so-called spring offensive has progressed relatively quickly, and serious issues may lie ahead in the near future. 1/ Image
Defending forces in the area initially consisted of newer, less capable brigades, such as the 142nd, 155th & 157th. Elements from other units were also present. Reserves have been brought in – first the 36th marine brigade, and now the 82nd air assault brigade, among others. 2/
Russia's probable operational objectives for the coming months in the area include:

Formation of an encirclement threat around Kostiantynivka

Formation of an encirclement threat around Pokrovsk

Disruption of Ukrainian supply & command elements in the cities in the AO 3/ Image

Russia has five active air bases near northern Finland and Norway. In this thread, I will go through the bases and their recent changes in activity and infrastructure, and how the war in Ukraine has affected them.

There have been some surprising developments. 1/ Image
The five air bases are located in Murmansk oblast: Severomorsk-1, -2 and -3, Monchegorsk and Olenya. There are more air bases near Finland further south in Karelia and St. Petersburg, but currently most of the largest and militarily active ones are in the north. 2/ Image
In June 2022 Russia announced plans to repair several of the northern air bases. The work has begun. In Severomorsk-1, fighter shelters on the eastern side of the field were repaired somewhere between 2023-24. However, in Severomorsk-2, there are more surprising changes. 3/ Image

Russia is developing its military infrastructure and conducting organizational reforms near Nato’s northern flank, especially near Finland. News agencies from different countries have asked me about the topic, and in this thread I will share some recent observations. 1/ Image
Firstly, a brief overview of the organisational level. In 2024, Russia reestablished the Leningrad Military District (LMD) as a part of a larger reform of the military districts. The LMD covers the north-western Russia, including Baltic and arctic directions. 2/ Image
At the same time, Russia is expanding its existing brigades into divisions and bringing entirely new troops into Finland's neighboring regions. For example, the 138th Guards Motor Rifle Brigade from Kamenka was recently transformed into the 69th Motor Rifle Division. 3/ Image

Putin declared a temporary ceasefire. What can be expected?

Firstly, Russia only makes such an announcement if it benefits Russia's diplomatic or military goals. Russia isn't suddenly seeking a quick peace, this is most likely a measure related to ongoing negotiations. 1/ Image
Putin says that Russian forces must be ready to repel potential ceasefire violations and provocations.

It's possible Russia will try to accuse Ukraine of breaking the ceasefire, which could then be used as evidence of Ukraine's unwillingness to reach a peace settlement. 2/
Russia may be trying to show the Trump administration that it has some desire for peace. A minimal gesture of goodwill may buy political points from the United States, although its actual impact on the war is likely to be small. 3/
