Russia upgrades Iskander and Kinzhal missiles to overwhelm Ukraine’s Patriot defense systems

Russia has updated the guidance software of its Iskander and Kinzhal ballistic missiles, sharply reducing Ukraine’s Patriot interception rate near Kyiv. The development raises concerns about Ukraine’s winter energy security as Moscow aims to overwhelm missile defenses.
A Financial Times investigation published on October 2, 2025, reports that Russia has upgraded the terminal flight behavior of its 9K720 Iskander M and Kh-47M2 Kinzhal ballistic missiles, cutting Ukraine’s Patriot interception rate around the capital. Ukrainian and Western officials told the Times that Kyiv’s ballistic kill rate fell from roughly 37 percent in August to about 6 percent in September as incoming missiles flew a conventional midcourse profile before executing abrupt endgame dives and lateral shifts intended to break radar track and outpace firing solutions. The disclosure follows a summer of strikes that damaged drone production facilities in and around Kyiv, underscoring a rapid adaptation cycle in which Russian guidance software is tuned specifically to defeat Patriot’s endgame.Follow Army Recognition on Google News at this link

Patriot remains Ukraine’s only fielded system with a credible ballistic missile defense capability. The system’s AN/MPQ-65 series fire-control radar builds high-quality tracks and feeds engagement commands to the hit-to-kill PAC-3 family, whose lethality depends on precise terminal guidance and split-second geometry. The PAC-3 Missile Segment Enhancement adds a dual-pulse solid rocket motor for extended battlespace and retains an active radar seeker in the nose, giving crews more energy and maneuver authority at intercept. Those strengths are maximized when the radar can maintain a stable track through the final seconds; they are stressed when a target suddenly steepens its dive angle, throws cross-range maneuvers, or shortens time of flight with a near-vertical terminal plunge.
On the threat side, the 9M723 Iskander has long been credited with quasi-ballistic behavior and aggressive endgame agility. It flies lower than classic ballistic arcs, can vary apogee, and reportedly performs pull-ups and lateral jinks that complicate filter stability inside defender radars. Kinzhal, derived from the Iskander airframe and launched by MiG-31K or Tu-22M3 aircraft, brings higher terminal velocities, potentially up to hypersonic speeds in the dive, with similar maneuver logic layered on top. What appears to have shifted since late summer is not the airframe but the guidance and control software: timing of terminal maneuvers, selection of dive angles, and bias toward track-breaking kinematics designed to arrive inside Patriot’s look angles just as interceptors commit.
For Ukrainian operators, the operational math has become harsher. Batteries must prosecute ballistic tracks while also covering low-flying cruise missiles and one-way attack drones in mixed raids. When a ballistic target begins to “snake” or plunge in the last seconds, crews face compressed decision timelines, higher interceptor expenditure per raid, and increased risk that a committed missile will miss if the threat’s vector change exceeds seeker gimbal or divert capability. That dynamic pushes commanders to reposition scarce launchers to protect power infrastructure and defense industry nodes ahead of winter, increase ready-to-fire loadouts, and rework engagement doctrines to emphasize earlier cueing, tighter sensor fusion, and layered fires that keep a medium-range guard on the Patriot battery itself.
The answer, Western officials and industry engineers suggest, would be to speed the defender’s adaptation loop. Software updates for both radar processing and interceptor guidance laws, revised look-angle tables, and tactics that distribute launchers and stack sensors can claw back lost probability of kill. Integrating additional medium-range systems to engage maneuvering threats slightly earlier in the endgame also helps preserve PAC-3 inventory for the most stressing shots, while multisite cueing reduces the chance a single terminal jink can break track across the battery’s field of view.
Moscow is signaling a renewed winter campaign against Ukraine’s energy grid, betting that improved endgame survivability will deplete interceptors faster and generate more leak-throughs against transformers and substations. Kyiv is pressing partners for additional Patriot batteries, reloads, and radar spares while European and U.S. production lines ramp to meet simultaneous Middle East and Indo-Pacific demand. The balance now hinges on software, supply chains, and operator proficiency as much as pure missile performance. Each Russian raid that keeps Kinzhal and Iskander inventories viable extends coercive leverage; each delivery of Patriot components and each doctrinal tweak marginally restores deterrence over Ukraine’s critical infrastructure.
