In the last 24 hours, more information has come out on yesterday’s purge of the Baltic Fleet command structure. First of all, the size of the purge is unprecedented, with around 50 high ranking officers being removed, including squadron and brigade commanders. Second, it is highly unusual for removals of top military officials (or of any senior officials in present-day Russia) to be public and openly for cause, rather than officially being described as being for health reasons or because the individual(s) were ready to retire.

Clearly, for the purge to be so large and so open, the misconduct in the Baltic Fleet had to be very serious and very widespread. Yulia Nikitina and Irina Tumakova from Fontanka.ru have published a long article documenting the faults attributed to the fleet’s now-former leadership. The condition of the fleet under Viktor Kravchuk had supposedly declined when compared to how it was under his predecessors, who received much less financing than he did in the last four years.

Nikitina and Tumakova discuss unconfirmed rumors about a collision between the recently completed Krasnodar diesel submarine and a Polish vessel (variously described as either an intelligence collection ship or Poland’s single remaining Kilo submarine). They also mention the poor state of housing for Baltic Fleet officers and obvious failures during recent exercises, such as when a submarine that was towed out to sea started to emit smoke rather than submerging and had to be returned to pier for repairs.

But if that was the extent of the problems, the leadership change is unlikely to have been so broad or so public. The most likely cause for the way this purge has been carried out is corruption. As Nikitina and Tumakova note, back in 2012 Kravchuk was tasked with creating the Kaliningrad defense region, a large joint military grouping that is to combine naval, aviation, and ground forces units under the command of the Baltic Fleet commander. At that time, Kravchuk was given command of strike aviation, air defense units, Iskander units (when located in Kaliningrad) and four infantry brigades that make up the 11th army corps.

The establishment of the 11th Army Corps required the construction of barracks, housing, and other facilities. The money that was allocated to these tasks was spent elsewhere or embezzled and the command proved to be unprepared to take in the additional troops. Furthermore, Kravchuk was known to have close ties with criminal “authorities” in Kaliningrad, including the “Amber baron” Viktor Bogdan, who, in addition to cornering the amber trade in the region seems to have also been involved in stealing diesel fuel from Baltic Fleet ships.

In other words, the Baltic Fleet purge appears to be a signal to other Russian military commanders (including mid-level ones) that corruption that has a negative effect on combat readiness will not be tolerated and will result in punishment far more severe than the usual honorable retirement given to senior officials who misbehave.
