The upper stage named here is the wrong Briz variant.

Kosmos-2504 launched on a Rokot/Briz-KM mission. Open-source tracking analyses of the mission identify the object it approached as the Briz-KM stage that delivered it to orbit. A TASS report on Rokot launches likewise states that Rokot missions use the Briz-KM upper stage.

So describing Kosmos-2504's early maneuvers as taking place near a Briz-M stage is incorrect; it should be Briz-KM.

Open sources distinguish two different Russian systems named Burevestnik.

• 9M730 Burevestnik is a nuclear-powered cruise missile. CSIS's Missile Threat identifies it as the "9M730 Burevestnik ... cruise missile" and describes a test launch from the Kapustin Yar missile range.
• The anti-satellite project called Burevestnik is a separate space project with the military index 14K168. Bart Hendrickx's detailed review in The Space Review says that 14K168 is an air-launched anti-satellite system, and explicitly states that the 9M730 cruise missile name "has no connection whatsoever to the ASAT project."

So the article's phrase incorrectly combines the cruise-missile designation 9M730 with the separate ASAT project 14K168, treating them as the same weapon when the cited sources say they are not.

The text incorrectly equates 9M730 Burevestnik with Project 14K168 Burevestnik.

According to CSIS, 9M730 Burevestnik is a nuclear-powered cruise missile. By contrast, The Space Review identifies 14K168 Burevestnik as a separate anti-satellite space complex and says the 9M730 missile name "has no connection whatsoever to the ASAT project." The same article also notes that the 14K168 project had been developing through procurement records and was not the weapon publicly unveiled by Putin in 2018; the 2018 unveiling was of the 9M730 cruise missile.

So the article is wrong to present 9M730 and 14K168 as the same system.
