Air Defense Makers: Patriot, NASAMS and IRIS-T

What Defines This Group

Air-defense makers are not a single industry. They range from trillion-dollar-scale aerospace primes whose missile work is one division among many, to focused national champions and to private family firms. What unites them is that their products now form the spine of Ukraine's protection against an air threat that mixes cheap one-way attack drones, subsonic cruise missiles and high-speed ballistic missiles. The table below summarizes the listing status and approximate parent market capitalization of each maker.

⚠ Market-cap figures are rounded approximations as of the dates shown, from public market-data aggregators; values change daily. RTX ~$245 bn and LMT ~$130 bn per stockanalysis.com (as of June 2026); Kongsberg ~NOK 370 bn per stockanalysis.com (as of April 2026); Rheinmetall ~€55 bn and Saab ~SEK 283 bn per stockanalysis.com (as of June 2026). Diehl Defence and MBDA are privately held and not separately listed.

The Layered Air-Defense Problem

The reason Ukraine fields so many systems is that the threat is layered, and no single weapon answers all of it affordably. At the top sit ballistic missiles — Iskander-class and air-launched Kinzhal — that arrive at high speed and steep angles, demanding hit-to-kill interceptors and powerful radars. In the middle band are cruise missiles and crewed aircraft, fast but lower and more predictable, where medium-range systems such as NASAMS and IRIS-T excel. At the bottom is the volume problem: swarms of cheap Shahed-type one-way attack drones designed to saturate and exhaust the defense.

Each layer has a different cost logic. Using a multi-million-dollar interceptor to down a drone that costs a fraction of that is a losing exchange over time, so guns and short-range missiles are reserved for the cheap threats while scarce high-end rounds are husbanded for ballistic and cruise targets. This is why the maker landscape spans both the giant interceptor primes and the gun-and-radar specialists.

Sensors tie the layers together. Early-warning and fire-control radars from RTX, Saab and others must detect, classify and cue the right shooter for each incoming object. The integration challenge — networking different national systems into one picture — is as important as any individual launcher, and it is where command-and-control software from firms like Kongsberg earns its place.

Patriot and PAC-3

Patriot is the most prominent name in Ukrainian air defense, and it is the product of two companies rather than one. RTX Corporation is the system prime, responsible for the radar, the launchers and the command-and-control backbone. Lockheed Martin builds the PAC-3 and the more capable PAC-3 MSE — the hit-to-kill interceptors that physically collide with incoming warheads and give Patriot its credible defense against ballistic missiles. Both are large NYSE-listed primes, with RTX valued near $245 billion and Lockheed Martin near $130 billion in June 2026.

The economics are stark. Open-source estimates put a complete Patriot battery at roughly USD 1 billion, and the cost is dominated by interceptors. PAC-3 MSE unit prices have been reported from around USD 4 million in earlier budget documents to about USD 5 million in more recent ones, with full export packages quoted higher. A 2025 U.S. Army contract covered roughly 1,970 PAC-3 MSE interceptors for about USD 9.8 billion, underlining how interceptor supply, not launchers, is the binding constraint.

For Ukraine, Patriot is the only widely fielded Western answer to Russian ballistic missiles, which makes each battery strategically precious and each engagement a careful accounting of finite rounds. The bottleneck is not the willingness to send systems but the pace at which interceptors can be produced and replaced.

NASAMS and IRIS-T

Below the ballistic-missile tier, two systems do much of Ukraine's day-to-day work against cruise missiles, aircraft and some drones. NASAMS — a joint product of Norway's Kongsberg Gruppen and RTX — pairs Kongsberg's fire-distribution and command system with RTX-supplied AMRAAM and AIM-9X effectors. It has been among the most heavily delivered medium-range systems in the war, with Ukrainian and allied officials describing more than ten systems supplied as part of a multi-national package, and Norwegian sources crediting it with high intercept rates.

IRIS-T SLM, built by Germany's Diehl Defence, is the other medium-range workhorse. Diehl is privately held and family-owned, so unlike the listed primes it has no public market capitalization — a reminder that some of the most important suppliers never appear on a stock screen. Diehl has indicated Ukraine is slated to receive around 18 IRIS-T systems in total, with roughly half delivered by early 2026, further batteries arriving through the year, and a large follow-on package reported in spring 2026.

Together NASAMS and IRIS-T form the affordable backbone of the medium layer, using interceptors that cost a fraction of a PAC-3 round while still reaching the cruise-missile and aircraft threats that would otherwise force Patriot to expend its scarce inventory.

Short-Range: Skyranger, Gepard, RBS 70

The cheapest and most numerous threat — the one-way attack drone — is best met not with missiles at all but with guns and very short-range effectors. Rheinmetall is central here. Its legacy Gepard self-propelled anti-aircraft gun, dusted off and resupplied with ammunition, became one of the most cost-effective counter-drone tools of the war, while the newer Skyranger gun-and-missile turret is explicitly designed for the swarm problem. Rheinmetall, listed on XETRA and valued near €55 billion in June 2026, has also become a major node in European ammunition and air-defense supply.

Sweden's Saab AB rounds out the short-range and sensor picture. Its RBS 70 and laser-guided RBS 70 NG offer man-portable and vehicle-mounted point defense, while its Giraffe radar family feeds the wider air picture that other shooters depend on. Saab, listed in Stockholm and valued near SEK 283 billion, illustrates how a mid-sized national champion can punch above its weight in sensors.

The strategic point is fit-for-purpose economics: pushing the cheap-drone fight down to guns and short-range missiles preserves multi-million-dollar interceptors for the targets that actually require them. The short-range layer is therefore not a junior partner but the financial release valve for the entire architecture.

Cost-Exchange and Outlook

The defining metric of this war's air campaign is the cost-exchange ratio — how much it costs to shoot down a threat versus how much that threat cost to launch. Russia's strategy of mass, cheap drones is designed to make the defender spend more than the attacker, and it has pushed every maker toward cheaper effectors, gun-based solutions and emerging directed-energy options. The U.S. Army's reported interest in a sub-USD-1-million Patriot-family interceptor is one symptom of this pressure.

MBDA sits at the high end of the European response. As a joint venture of BAE Systems, Airbus and Leonardo it is not separately listed, yet its Aster missile and SAMP/T system give Europe a long-range alternative to Patriot that has been supplied to Ukraine. The presence of two unlisted but pivotal players — MBDA and Diehl — alongside the giant listed primes is a structural feature of the sector worth remembering for anyone reading market caps as a proxy for importance.

The outlook is one of sustained demand and strained supply. Interceptor production for Patriot, NASAMS and IRIS-T is being expanded, but lead times are long and Ukraine competes with allied rearmament for the same lines. The makers profiled here are scaling capacity, but the binding question through 2026 and beyond is whether interceptor output can keep pace with the threat — not whether the systems themselves can be built.
