Ukraine’s military intelligence says overnight strikes on the night of Nov 1 to 2 disabled core pieces of Russia’s air defense in occupied Crimea, including the command post of an S-400 Triumf battalion. The reported loss of a 92N6E engagement radar and other sensors complicates Russian coverage over Crimea and the Black Sea approaches.
On 3 November 2025, Ukrainian military intelligence confirmed overnight strikes that disabled core elements of Russia’s air-defense architecture in occupied Crimea, including the command post of an S-400 “Triumf” battalion. The attack, carried out during the night of 1–2 November, reportedly destroyed a 92N6E multifunctional radar and the autonomous power-supply equipment feeding the S-400 command post, with additional hits on an AORL-1AS airfield surveillance radar and a P-18 “Terek” VHF set. This latest operation follows a months-long campaign targeting Russian sensors and engagement radars across the peninsula and comes with fresh video evidence released by Kyiv. The development is relevant because it directly degrades Russia’s integrated air-defense network over Crimea and the approaches to the Black Sea, as reported by the Main Directorate of Intelligence of the Ministry of Defence of Ukraine.

According to an intelligence statement and verified footage, the S-400 unit was struck while on combat duty, disabling the 92N6E fire-control radar and the command post’s power system. By pairing a sensor kill with a power-node hit, the attackers aimed not only to blind the battery but to keep maintenance crews from rapidly restoring the command link, lengthening downtime and complicating any immediate reconstitution. Agency-released details consistently point to a target set that includes the 92N6E radar, autonomous power infrastructure, AORL-1AS, and P-18 systems.
The destruction of another Russian air-defense system in Crimea matters operationally because the 92N6E is the S-400’s primary engagement radar, responsible for precision tracking and missile guidance. Removing it from the network forces the battery to rely on backup sensors, narrows the engagement envelope, and increases Ukraine’s chances of threading drones and standoff munitions through reduced coverage. Knocking out the autonomous power supply at the command post further delays restoration, as mobile generators and cabling must be moved in under threat, and technicians must test and synchronize surviving components without the original power backbone. In parallel, the loss of an AORL-1AS airfield surveillance radar diminishes the Russian picture over runway approaches, while the P-18 “Terek” hit degrades long-wavelength early warning that is often used to cue on low-observable or low-RCS targets. Although Russian forces maintain layered defenses and some redundancy, each eliminated node increases reaction times and expands the windows in which Ukrainian strikes can be launched or exfiltrated.
For Russia, the immediate impact is a riskier operating environment over western and central Crimea. With one S-400 command node disrupted and multiple radars offline, commanders must either strip assets from other sectors to plug the gap or live with degraded coverage during a period when Ukrainian long-range strikes are recurring. Reallocation imposes opportunity costs, secondary fronts and key logistics corridors receive less protection, and accelerates wear on surviving systems that are forced into higher duty cycles. The damage also compels additional force-protection measures around radar parks and command posts, diverting combat engineers, air-defense troops, and electronic-warfare teams into static guard roles.
For Ukraine, the benefits are tangible. First, reduced radar coverage increases the survivability of reconnaissance and strike drones that have become central to shaping fires across Crimea. Second, disabling the S-400’s fire-control and power nodes complicates Russian attempts to intercept incoming cruise missiles or guided rockets, widening the corridor for deep-strike options against fuel depots, ammunition stores, rail junctions, and maritime logistics sites. Third, each successful hit adds pressure on Russian air-defense logistics: radars like the 92N6E are not quickly replaced in theater, spares are finite, and transport to Crimea relies on vulnerable routes that Kyiv has repeatedly targeted.
The strategic implications reach beyond the tactical map. Militarily, the attack continues a pattern of sensor suppression across Crimea intended to fracture Russia’s integrated air-defense system into isolated bubbles and shorten Ukrainian kill chains. Geostrategically, a thinner Russian air shield over Crimea raises the risk calculus for basing and sortie generation from peninsula airfields, potentially pushing Russian aviation and air-defense assets further east and altering patrol and intercept patterns over the Black Sea. Geopolitically, it signals to partners that Kyiv can repeatedly disrupt high-value air-defense components despite Russian adaptation, reinforcing the argument for sustained supplies of long-range strike enablers and complex UAVs. It also tightens the squeeze on Russia’s Black Sea posture by making critical infrastructure, fuel farms, repair yards, and coastal surveillance sites, more vulnerable to follow-on strikes.
This latest action also fits a broader tempo. In late October, Ukrainian intelligence units claimed strikes against other radar assets on the peninsula, including a 96L6, P-18 and Nebo-U, demonstrating a deliberate focus on the “eyes” and “nerves” of the Russian network rather than just the launchers. The November 1–2 operation extends that logic by pairing radar kills with a direct hit on the S-400 command post’s power architecture, aiming for longer, more complex recovery timelines and cumulative attrition of highly specialized equipment and crews.
Taken together, the evidence points to a systematic effort to blind, de-energize, and fragment Russia’s air-defense coverage over Crimea. With a 92N6E engagement radar out of action, auxiliary sensors damaged, and a command-post power node down, Ukraine has carved out new tactical windows and increased the strain on Russian logistics and command. If Kyiv can sustain this pace, cycling sensor kills with attacks on power and command, the peninsula’s air picture will grow patchier, Russian reaction times will lengthen, and follow-on strikes against operational infrastructure will become more difficult to stop, as reported by the Main Directorate of Intelligence of the Ministry of Defence of Ukraine and corroborated by Ukrainian media citing the agency’s release.
