Ukraine’s Stealth PRYMARY Campaign in Crimea Targets Russia’s Radar and Nerves
Ukraine’s military intelligence says its PRYMARY unit has spent the past month systematically striking Russian radar, air defenses and logistics targets across occupied Crimea, from Baltika‑B and Neva systems to a regimental command post and patrol boats. For Russian commanders and Black Sea planners, the peninsula is looking less like a sanctuary and more like contested space.
Crimea, long sold to Russians as a secure symbol of their 2014 annexation, is being turned into a testing ground for Ukraine’s deep‑strike doctrine. Kyiv’s military intelligence service says a specialized unit has spent the past month systematically attacking Russian radar, air defenses, communications and logistics nodes across the occupied peninsula.
Ukraine’s Main Intelligence Directorate (HUR) said its PRYMARY unit hit a string of high‑value targets, including Baltika‑B, Neva and Kasta‑2E2 radar systems; a Pole‑21 electronic‑warfare complex; a Strela‑10 short‑range air‑defense system; and the command post of Russia’s 503rd Motorized Rifle Regiment. The unit also reported destroying or damaging four communications antennas, two Geran/Gerbera drone relay stations, various vehicles, a roadstead boat and a Project 05060 craft, among other assets.
The claims cannot be independently verified, and Moscow has not given a full accounting of losses. But they fit with a visible pattern of explosions, fires and disrupted military activity in Crimea in recent weeks, and with Kyiv’s stated strategy of making the peninsula, including its ports and airfields, untenable as a rear base for Russia’s war.
For Russian forces deployed there, the operational consequences are tangible. Knocking out radar like Kasta‑2E2 and Neva degrades air‑picture coverage over parts of Crimea and the approaches to the Black Sea Fleet’s facilities. Damaged Pole‑21 systems weaken the electronic shield meant to disrupt incoming Ukrainian drones and missiles. Disrupting drone relays and communications antennas forces units to improvise, rely on backup networks or operate with less real‑time awareness of threats.
For Ukrainian planners, each successful strike in Crimea serves both a military and psychological purpose. Militarily, it chips away at Russia’s ability to use the peninsula as a secure launchpad for missile and drone attacks into mainland Ukraine and as a logistics hub feeding southern front lines. Psychologically, it sends a message to Russian troops and civilians alike that distance from the front no longer guarantees safety. The peninsula’s air‑raid sirens and sudden blasts are designed to erode the sense of inevitability around Russian control.
The broader strategic effect extends into the Black Sea. The more Russia has to disperse or harden its radars, command posts and air defenses in Crimea, the more stretched its resources become in protecting naval routes and assets. That in turn can open windows for Ukrainian anti‑ship strikes or for commercial shipping to resume limited traffic along corridors Kyiv has been promoting as alternative export routes.
The campaign also speaks to an evolving form of warfare in which a relatively small, specialized unit can have outsized impact by systematically targeting the sensors and nervous system of an occupying force rather than just its front‑line troops. Strikes on command posts and communications infrastructure in Crimea may not produce immediate territorial gains, but they can complicate Russian efforts to coordinate defenses across the south, slowing response times and increasing the chance of costly mistakes.
The concise lesson is that once a territory becomes a logistics hub, every radar, relay mast and command bunker there turns into a frontline target – and the side that can hit those nodes cheaply and repeatedly shifts the balance of risk.
The next indicators to watch include Russian moves to relocate key assets deeper into the peninsula or onto the Russian mainland, any reported personnel changes in units stationed in Crimea, and changes in the intensity of Russian missile and drone launches from the region. Equally important will be signs that Ukraine is integrating these strikes with broader offensives or with efforts to widen its Black Sea export corridors, turning tactical sabotage into strategic leverage.
