Ukraine’s military intelligence directorate, known as HUR, claims its elite Prymary unit destroyed a 96L6 radar station tied to Russia’s S-400 Triumf air defense system in occupied Crimea. The strike, part of a broader series of attacks on Russian radar infrastructure and naval assets during February 2026, represents one of the most significant claimed hits against Moscow’s layered air defenses on the peninsula. If confirmed independently, the loss of a 96L6 acquisition radar would degrade the detection range of an S-400 battery, creating gaps that Ukrainian drones and missiles could exploit.
What is verified so far
Multiple Ukrainian official and state-affiliated sources describe a coordinated campaign against Russian radar stations in Crimea during late February 2026. The Ukrainian General Staff reported that defense forces struck two radar stations during the night of February 26: a P-18 Terek and an RSP-6M2 located in Dzhankoi, according to the Ministry of Defence’s news agency ArmyInform. That communique named specific systems and a precise location, giving it a higher degree of operational detail than many wartime claims and establishing that at least some Russian radar assets in Crimea were hit on that date.
Separately, Ukrainian state news agency Ukrinform reported that HUR’s Prymary special unit struck three radar stations and a BK-16 landing craft in occupied Crimea. The radars listed were the 96L6 component of the S-400 Triumf, the P-18 Terek, and the 55Zh6U Nebo-U. The 96L6 is the target most directly linked to the headline claim. It serves as the acquisition and battle management radar for S-400 batteries, feeding target data to the system’s fire-control elements. Without it, an S-400 unit can still function using other sensors, but its ability to independently detect and track targets at long range is sharply reduced.
HUR itself has published primary documentation of related operations. The directorate released exclusive video of a separate strike that, according to its own official statement, destroyed a Zircon hypersonic missile launcher in Crimea. That package showed drone footage of the target and impact, demonstrating a pattern of pairing operational claims with visual evidence. The same institutional ecosystem surfaced the material through Ukraine’s broader coordination platform for wartime information and via HUR’s own sanctions portal, underscoring that the agency has established channels for publicizing sensitive operations.
While the Zircon strike is a distinct event from the radar attacks, it is important because it shows how HUR tends to communicate: announce a high-profile operation, then release corroborating imagery when security conditions permit. That pattern underpins the credibility many observers assign to HUR-linked claims, even when direct visual proof is not yet available for every reported target.
Independent Ukrainian media have echoed and expanded on the official narrative. Hromadske, a well-known outlet, reported that the Prymary unit conducted multiple strikes in February 2026 targeting Russian assets in occupied Crimea, explicitly listing an S-400 radar station alongside boats and warships in its coverage of the operation. This account aligns with the Ukrinform report and suggests a sustained operational tempo rather than a single isolated attack.
The official military picture from Kyiv is framed by the General Staff, whose updates are hosted on the Armed Forces portal. Those communiques, including the February 26 report on radar strikes near Dzhankoi, provide the baseline chronology: Ukrainian forces were actively engaging Russian radar infrastructure in Crimea at the time Prymary’s actions were said to have taken place. Together, these sources establish that radar sites were hit, that HUR’s special unit was involved in at least some of the operations, and that one of the targeted systems was associated with the S-400 network.
What remains uncertain
The central gap in the evidence is the absence of a primary HUR release specifically documenting the 96L6 radar destruction with the same level of detail and footage that accompanied the Zircon launcher strike. The claim that an S-400-linked radar was hit rests on secondary reporting from Ukrinform and Hromadske, both of which cite HUR but do not link to a standalone primary release with video proof for this particular target. That matters because HUR has shown it can and does publish such evidence when it chooses to. The fact that no equivalent primary package has surfaced for the 96L6 claim leaves room for skepticism about the extent of damage or the precise system struck.
Russia has not publicly confirmed the loss of any S-400 component in Crimea during this period. Moscow routinely withholds acknowledgment of equipment losses, so the silence is neither confirmation nor denial. Independent open-source intelligence analysts have not, based on the reporting surveyed here, published satellite imagery or geolocation data corroborating the destruction of a 96L6 radar at a specific site. Without that third-party verification, the claim remains single-sourced to the Ukrainian side and filtered through Ukrainian media.
The weapon systems and exact methods used by the Prymary unit in these strikes are also unclear. Secondary reports describe the attacks in general terms without specifying whether the unit employed naval drones, loitering munitions, cruise missiles, or some other platform. Understanding the delivery method matters for assessing whether Ukraine can replicate such strikes consistently or whether this was a one-off success enabled by unusual conditions, such as favorable weather, Russian complacency, or inside information about radar operating schedules.
There is also a question of how many distinct operations are being described. The General Staff communique from February 26, as relayed by ArmyInform, names two radar types, the P-18 Terek and RSP-6M2 in Dzhankoi, while the Ukrinform and Hromadske accounts describe three radars, adding the 96L6 and 55Zh6U Nebo-U and mentioning a BK-16 landing craft. Whether these reports cover the same night, overlapping operations across several days, or entirely separate missions is not fully resolved in the available sourcing. The P-18 Terek appears in both accounts, suggesting some overlap, but the timeline and geographic details do not perfectly align, leaving room for ambiguity about sequencing and locations.
How to read the evidence
The strongest piece of primary evidence in this story is not about the S-400 radar at all. It is HUR’s documented strike on the Zircon launcher, which demonstrates that the agency is capable of mounting complex attacks in Crimea and then publicizing them with verifiable imagery. That operation, distributed through HUR’s own channels and mirrored on official Ukrainian platforms, shows that Ukrainian special units can reach high-value assets on the peninsula and that Kyiv is willing to reveal some operational details after the fact.
Against that backdrop, the 96L6 claim sits in a middle ground between confirmed fact and unsubstantiated rumor. On one side, multiple Ukrainian outlets with direct access to official sources describe Prymary’s actions in similar terms, naming the same families of radar and emphasizing the link to the S-400 system. On the other, the absence of primary visual evidence and of independent geospatial analysis means outside observers cannot yet verify exactly what was hit, how badly it was damaged, or whether it has since been repaired or replaced.
For readers trying to assess the credibility of wartime claims, a few practical guidelines apply. First, look for convergence: here, ArmyInform, Ukrinform, Hromadske, and official military portals all point to an uptick in Ukrainian strikes on Russian radar and naval assets in Crimea in late February 2026. That convergence supports the broader narrative of a campaign against Russian air-defense infrastructure. Second, distinguish between what is directly evidenced (radars in Dzhankoi were struck) and what is inferred or indirectly sourced, such as the precise destruction of a specific 96L6 unit.
Third, consider the incentives and track records of the actors involved. Ukrainian institutions have an obvious interest in highlighting successful deep strikes, particularly against prestigious systems like the S-400. However, HUR’s habit of backing some of its most prominent claims with video and detailed documentation also creates reputational costs if it were to exaggerate too far beyond what later imagery might show. That dynamic does not eliminate the possibility of overstatement, but it does encourage a degree of discipline in how operations are presented.
Finally, remember that in a high-intensity war, information often lags events. It is possible that imagery or more granular documentation of the 96L6 strike exists but has not yet been cleared for release, or that subsequent satellite passes will reveal damage consistent with the Ukrainian accounts. It is equally possible that later analysis will show a different radar model was hit, or that the system was only temporarily disabled. Until such evidence emerges, the fairest reading is that Ukraine has credibly demonstrated attacks on Russian radar infrastructure in Crimea, and that a successful strike on an S-400-related radar is plausible but not independently confirmed.
In that sense, the Prymary operation illustrates the broader fog surrounding the contest for Crimea’s airspace. Ukraine is clearly probing and degrading Russian sensors on the peninsula, while Russia is working to patch vulnerabilities and maintain the impression of an impenetrable shield. The truth about any single radar may remain murky for some time, but the pattern of strikes and the cautious wording of official and media reports together suggest that Crimea’s air-defense picture is becoming more contested, and more fragile, than Moscow would like to admit.
