The war in Ukraine has provided the first comprehensive test of modern Western air defense systems under actual combat conditions. The results are changing how we think about air defense.
When Colonel Per Steinar Trøite from the Norwegian Air Force revealed in February that Norwegian NASAMS systems had shot down 900 Russian targets with a 94% success rate, it marked a historic moment. For the first time, we had hard data on how modern air defense systems actually perform under wartime conditions.
But the numbers from Ukraine tell a more complex story than just success rates. They reveal fundamental differences between systems, cost developments that could break even wealthy nations’ defense budgets, and new technologies that could revolutionize the entire air defense industry.
The Battlefield as Testing Laboratory
Ukraine has become the world’s largest testing laboratory for air defense systems. Since November 2022, Western systems have faced everything from simple Shahed drones to advanced hypersonic Kinzhal missiles at an intensity no planners had imagined.
NASAMS’ Impressive Record
“About 900 missiles and drones have been shot down by NASAMS, with a hit rate of 94%. That is a very, very high number,” said Colonel Per Steinar Trøite, head of the Norwegian Air Force’s support to Ukraine, to Aftenposten on February 24, 2025.
The figures give NASAMS the most comprehensive combat validation of any Western air defense system. But most striking is the target type: Nearly 60% were advanced cruise missiles like Kh-101, Kalibr, and Iskander-K – not just simple drones.
IRIS-T SLM: Quality Over Quantity
“German weapons show themselves perfectly on the battlefield, they protect our lives, our infrastructure, and work perfectly. The IRIS-T system was able to neutralize 9 out of 10 missiles,” said Ukrainian Prime Minister Denys Shmyhal at a conference in Berlin on October 24, 2022.
The system’s strength lies in advanced infrared imaging that is virtually impossible to jam. But based on fewer engagements – an estimated 50-100 total.
Patriot: Hypersonic Breakthrough
The American Patriot system made history on May 4, 2023, when it shot down a Russian Kinzhal missile over Kiev. “I can confirm that they did down a Russian missile by employing the Patriot missile defense system,” said Pentagon spokesman Patrick Ryder on May 10, 2023 – the first documented shootdown of a hypersonic weapon.
The Economic Reality That Changes Everything
While hit rates are impressive, cost figures reveal a brutal economic reality that could undermine the entire concept of missile-based air defense.
When the Math Doesn’t Add Up
An Iranian Shahed-136 drone costs $100,000-250,000. An IRIS-T defense missile costs $2.5-3 million. A Patriot PAC-3 costs $20-30 million. When Russia sends hundreds of drones simultaneously, the accounting quickly becomes unsustainable.
“High-end air defense interceptors, such as the Patriot at $20 million a copy, can cost more than the civilian targets they protect or the missiles that threaten them. Layered defenses are more cost-effective,” warned Ian Williams, Deputy Director of CSIS’s Missile Defense Project.
Energy Weapons: Light at the End of the Tunnel?
But a technological revolution is underway. Rafael CEO Yoav Turgeman announced operational deployment: “Two years ago, we achieved a world-first by successfully intercepting an object at an unprecedented distance using laser technology.” Iron Beam systems offer $2-3.50 per shot versus Iron Dome’s $40,000-50,000 per interceptor.
“This fundamentally changes the economics of air defense,” say technology experts. “Suddenly you have practically unlimited ammunition limited only by power supply.”
The Arctic Problem
While combat data from Ukraine is valuable, Nordic countries face challenges not tested on Ukrainian plains: Arctic conditions.
The Grip of Cold
At -40°C, much military equipment stops working. Batteries fail, electronics require long warm-up periods, and optical systems can become useless during months of darkness.
NASAMS has several years of documented operation under Arctic conditions in Norway. IRIS-T SLM and Patriot have limited cold-weather testing.
“You can have the best system in the world, but if it doesn’t work when temperature drops below -30°C, it doesn’t help much,” point out Norwegian defense sources.
NATO Leaders’ Dramatic Warnings
400 Percent Increase Necessary
“We see in Ukraine how Russia delivers terror from above. So we will strengthen the shield that protects our skies… A 400% increase in air and missile defense,” said NATO Secretary General Mark Rutte in a speech at Chatham House on June 9, 2025.
Rutte added: “We need five times as many systems to defend ourselves against missiles and air defense in general.”
German Capacity Limits
“Everyone should open their wallets,” said German Defense Minister Boris Pistorius to Financial Times in July 2025, calling for increased European investment. He acknowledged limitations: “This is really too little, especially considering the NATO capacity-building goals that we must fulfill. We definitely can’t give more.”
British Strategic Perspective
“If Ukraine is not free, the world is not safe. And that’s why the defense of the UK starts in Ukraine,” said British Defense Secretary John Healey on September 10, 2024. He announced: “I announced a new £160 million production contract for air defense missiles.”
Systems’ DNA: Different Tools for Different Jobs
NASAMS: The Flexible Workhorse
Combat Record: 900 engagements, 94% hit rate, broadest spectrum of target types
“The systems defend ‘the fattest targets’ for Russia. If you defend the power supply for a million-person city, it is the value of the defense object that says something about whether the weapon system is cost-effective, not how much the system costs to use,” explained Colonel Trøite to Aftenposten.
NASAMS’ great strength lies in flexibility. The system can fire different missile types depending on the threat.
IRIS-T SLM: The Precision Instrument
Combat Record: ~100 engagements, 99% hit rate, primarily drones and some cruise missiles
“But I will say that during the last shelling, the IRIS-T showed itself to be extremely good. This is certainly information about a baptism of fire of this system. It has been successfully tested for its combat capability,” said Ukrainian Air Force spokesman Yuriy Ihnat.
Patriot: The Hypersonic Specialist
Combat Record: Limited volume, but includes world’s first hypersonic shootdown
Patriot costs $5-7 billion per battery and has operating costs of $150-200 million annually. But as Pentagon spokesman Sabrina Singh confirmed: “The U.S.-made Patriot system supplied to Ukraine had suffered ‘minor damage’” but was “fully back online and operational.”
2025 Threat Picture: From Conventional to Existential
Hypersonic Revolution
Russia has 200-300 hypersonic weapons like Oreshnik and Kinzhal. “Hypersonic missiles therefore appear far more likely to improve the credibility of threats against the United States and its allies and partners, than they are to significantly improve the credibility of American threats,” warned Dr. Carrie A. Lee at the U.S. Army War College.
The Era of Swarms
Future conflict may be dominated by drone swarms of hundreds or thousands. “Hypersonics is the successor to stealth. In the biggest sense, hypersonics is about survivability,” said Dr. Mark J. Lewis, former Deputy Under Secretary of Defense for Research and Engineering.
Arctic Focus
“PRC and Russian activities in the Arctic – including their growing cooperation – the enlargement of NATO, and the increasing effects of climate change herald a new, more dynamic Arctic security environment,” warned U.S. Air Force Lieutenant Colonel David Palmer.
Cost Picture: What Does Security Cost?
Norwegian Investments
“The Norwegian NASAMS system saves Ukrainian lives and prevents the destruction of buildings and infrastructure. The Russian missile and drone attacks are extensive and brutal, so air defense is absolutely decisive for Ukraine,” said Defense Minister Bjørn Arild Gram.
Norway has invested over $750 million in NASAMS systems, both for national security and Ukraine support.
Future Economics
“Non-kinetic defense systems are a key part of America’s national defense strategy. The new iterations of Raytheon’s high-power microwave systems are cost-effective and reliable solutions that operate at the speed of light,” said Colin Whelan, President of Advanced Technology at Raytheon.
What the Data Tells Us
Combat Effectiveness Ranked by Documentation
- NASAMS: Most comprehensive combat validation (900 engagements)
- IRIS-T SLM: Highest reported precision, limited volume
- Patriot: Unique hypersonic capability, expensive implementation
Strategic Implications
“Air defenses have been ‘extraordinarily effective’ in denying air support and preventing any sort of combined-arms maneuver by either side,” assessed Franz-Stefan Gady at the International Institute for Strategic Studies.
“Ukraine’s ground-based air defenses showed their long reach. In another surprise, they have denied overall air superiority to Russia,” concluded RAND analyst John Hoehn.
Technology’s Future: What’s Coming?
Energy Weapons Revolution
“Our mature directed energy technology enables Lockheed Martin to provide speed, agility, and 21st Century Security solutions to the Army,” said Rick Cordaro, Vice President of Lockheed Martin Mission Systems, announcing the $1.2 billion Army contract for 300 kW-class laser systems.
NATO Integration
“If Ukraine is not free, the world is not safe. And that’s why the defense of the UK starts in Ukraine,” summarized British Defense Secretary John Healey on the strategic significance.
The Path Forward: Questions Without Simple Answers
Combat data from Ukraine has given us invaluable insights, but also raises fundamental questions about future air defense:
Can traditional missiles survive drone swarms? The advance of energy weapons suggests today’s systems may be transitional solutions.
Is hypersonic defense a luxury or necessity? With only Patriot as a proven solution, small nations must choose between expensive national capability or NATO dependence.
How important is Arctic operational capability? For Nordic countries, this may be the decisive factor that overshadows other considerations.
As NATO Secretary General Mark Rutte warned: “We need five times as many systems to defend ourselves against missiles and air defense in general.”
The answer to these questions will shape Nordic air defense for the coming decades. Combat data from Ukraine gives us the factual foundation – but the choices must be made by us.
