Ukraine’s Deep Strikes Hit Russian Radar and Logistics Hubs
On 16 April 2026, Ukrainian forces reported destroying a Russian 35N6 ‘Kasta’ radar system in occupied Zaporizhzhia and deploying long-range FPV drones over Donetsk City, more than 60 km from the front. These actions highlight Ukraine’s growing deep-strike and counter-air capabilities.
Key Takeaways
- A Ukrainian National Guard aviation unit destroyed a Russian 35N6 "Kasta" radar in occupied Zaporizhzhia on 16 April 2026.
- Ukraine’s 1st Azov Corps used FPV drones to hit Russian logistics targets across Donetsk City, at distances exceeding 60 km from the front line.
- The strikes weaken Russian airspace monitoring and supply chains in rear areas.
- These operations demonstrate Ukraine’s expanding ability to project precision effects deep into Russian-held territory.
Around 10:01 UTC on 16 April 2026, Ukrainian sources reported that pilots from the 23rd brigade "Khortytsia" of the National Guard conducted a successful deep strike on a Russian 35N6 "Kasta" radar station located in Russian-occupied Zaporizhzhia region. The radar, used for monitoring airspace and detecting targets at very low altitudes, formed a core component of the local Russian air defense and early warning network.
According to Ukrainian accounts, the radar was operating on temporarily occupied territory, providing coverage and cueing for Russian air defense assets against low-flying aircraft and drones. Its destruction reduces Russian ability to track Ukrainian air and UAV activity across a portion of the southern theater, potentially opening windows for additional strikes.
In parallel, reports at approximately 10:01 UTC highlighted that FPV drones of Ukraine’s 1st Azov Corps had, for the first time, struck Russian logistics targets across Donetsk City while flying freely over the city center, more than 60 km from the frontline. This marks a notable increase in range and operational maturity of Ukraine’s FPV drone program, previously focused mainly on front-line or near-front targets.
The key actors in these developments are Ukrainian National Guard aviation and specialized FPV drone units, and Russian air defense and logistical structures. The 35N6 "Kasta" radar is designed to detect low-altitude threats, an important asset against drones and cruise missiles. Its loss will likely force Russia to reallocate other systems or accept a coverage gap. Meanwhile, the Azov Corps’ drone operations indicate an ability to navigate contested airspace over a major Russian-occupied city—implying effective route planning, possible exploitation of gaps in Russian electronic warfare, and growing operator skill.
These actions matter strategically for several reasons. First, sustained Ukrainian attacks on key enablers like radars degrade Russia’s integrated air defense system over time, making it harder to intercept future waves of drones and missiles. Second, successful strikes on logistics nodes in Donetsk City—such as warehouses, vehicle parks, or command facilities—complicate Russian sustainment of front-line units and force them to disperse or relocate assets, reducing efficiency.
For Russia, the incidents underscore vulnerabilities in rear areas once considered relatively secure. The need to protect more sites deeper in occupied territory strains air defense and electronic warfare resources, which are finite. Russia may respond by thickening air defenses around key urban hubs, increasing GPS jamming, and seeking to intercept drones earlier in their flight paths.
Internationally, Ukraine’s progress in long-range FPV use draws attention to the diffusion of inexpensive, highly effective precision capabilities to non-NATO militaries. It also reinforces Western arguments that supplying Ukraine with advanced sensors, communications links, and munitions can yield substantial battlefield effects even without large numbers of traditional aircraft.
Outlook & Way Forward
In the short term, Ukraine is likely to continue targeting Russian radar systems, command sites, and logistics hubs in occupied territories, leveraging both stand-off munitions and long-range FPV drones. Russia can be expected to adapt with enhanced air defenses, hardened facilities, and increased operational security measures in rear areas.
Analysts should watch for patterns in the types of targets hit in Donetsk and other occupied cities—whether Ukraine focuses on ammunition depots, fuel storage, headquarters, or transport hubs—as these will indicate its strategic priorities. Evidence of Russian redeployments or changes in logistics routes will also be important indicators of impact.
Over the medium term, the maturation of Ukraine’s deep-strike ecosystem may erode Russian confidence in the security of its occupied rear areas, potentially forcing a rebalancing of forces and resources away from the immediate front lines. This dynamic, if sustained, could incrementally shift the initiative on certain axes, even as Russia continues to press offensives elsewhere.
