The depletion of global interceptor missile stocks for Patriot systems has coincided with the technological evolution of Russian ballistic systems. Our material examines how Ukrainian engineers, military-tech startup developers, and the military are adapting to these challenges and learning to counter ballistic threats.
Why Are There Never Enough Missiles?
Most conventional surface-to-air missiles (such as the PAC-2 GEM-T) carry a fragmentation-high-explosive warhead: they detonate near the target and destroy it with a cloud of shrapnel. Against an aircraft or a cruise missile, this is sufficient. But if the fragments merely damage the tail of a ballistic missile plummeting at enormous speed, its massive warhead will still reach the ground by inertia. That said, the PAC-2 GEM-T is also capable of intercepting tactical ballistic missiles.
For more effective destruction of ballistic targets, however, Hit-to-Kill kinetic intercept technology is required — the technology embodied in the advanced PAC-3 MSE missiles, which collide directly with the enemy warhead on a closing trajectory. Production of such interceptors is extremely slow. In 2025, Lockheed Martin delivered a then-record 620 PAC-3 MSE rounds. At the same time, due to a sharp surge in demand, the United States and its allies have already launched large-scale production expansion, with a stated goal of approximately 2,000 interceptors per year.
Meanwhile, when a coalition in the Middle East fired more than 800 Patriot interceptors during a fresh escalation over the course of just a few days, deliveries to Ukraine dropped noticeably. The United States even made statements indicating that missiles purchased by European partners for Ukraine had been redirected to meet American requirements.
The Enemy’s Technological Evolution
Russia’s military-industrial complex has carried out an upgrade of the Iskander-M (9M723) operational-tactical missiles.
First, they received updated software enabling the missile to execute aggressive high-G maneuvers during the terminal phase of flight. This partially defeats the mathematical calculations of Patriot radars, forcing the interceptor to expend energy on sharp course corrections.
Second, the adversary has begun fitting the missiles with a 12-element digital phased-array antenna called the “Kometa-M12R-VT,” which provides resistance to conventional electronic warfare means.
From FrankenSAM to Sapsan: Ukraine’s Response
To preserve the remaining PAC-3 missiles exclusively for ballistic threats, Ukrainian specialists together with Western partners have deployed a hybrid FrankenSAM architecture. By developing unique digital interfaces, Ukrainian radars have been made interoperable with Patriot launchers, while legacy Soviet Buk systems have been enabled to fire American RIM-7 and AIM-9M missiles.
At the same time, Ukraine continues to operate rare Soviet S-300V1 systems equipped with 9M83 missiles, which are capable of engaging tactical ballistic targets, among others. In December 2025, Norway announced the allocation of more than 0.5 billion Norwegian kroner for the procurement of missiles for Ukraine’s S-300 systems.
In addition, the Ukrainian private company Fire Point is advancing the development of domestically produced ballistic missiles — the FP-7 (with a range of approximately 200–300 km) and the FP-9 (with a range of up to 855 km) — which will prospectively give the Armed Forces of Ukraine the ability to preemptively destroy Russian launch systems deep in the rear.
“Hacking the Missile’s Brain”: Next-Generation Electronic Warfare
The most innovative response to the interceptor missile shortage has been the Lima electronic warfare system from Ukrainian startup Cascade Systems. Rather than physically shooting down a missile, Lima performs satellite spoofing — jamming the genuine GPS/GLONASS signal and substituting false coordinates. As a result, the enemy missile’s inertial navigation system accumulates an error and steers the weapon into an open field instead of an infrastructure target.
To penetrate the protection provided by the latest 16-element Russian antennas, Ukrainian engineers rapidly developed the Lima Quant modification. Deploying a continuous electronic warfare dome over a major city costs approximately 5 million euros — equivalent to the price of just a single PAC-3 kinetic missile. In the first months of 2026, the system succeeded in deflecting dozens of Kinzhal missiles and cruise missiles from their targets.
Kinetic Drones and “Democratic Air Defense”
To defend against cheap strike drones that exhaust air defense resources, Ukraine has deployed a fleet of interceptor drones. Models such as the P1-SUN, Sting, Merops, and F7 LITAVR can accelerate to more than 300 km/h and physically ram enemy Shaheds. The cost of such an intercept is $1,000–2,000.
The Patriot missile shortage is pushing Ukraine not so much to find a direct replacement as to rebuild its entire air defense architecture. Expensive kinetic interceptors remain the tool of choice against ballistic targets, while electronic warfare, upgraded systems, indigenous missiles, and low-cost interceptor drones make it possible to distribute the load across different defensive layers. The multi-layered model is becoming one of the priority directions in the development of Ukrainian air defense under the conditions of a protracted missile war.
