Germany Diehl Defence
IRIS-T SLM
A German medium-range, ground-based air-defense system adapted from the IRIS-T air-to-air missile, using infrared homing to defeat aircraft, cruise missiles and drones with high resistance to jamming. It gained prominence after deliveries to Ukraine, where it reported a very high intercept success rate.

Availability & export
German export-licensed
BAFA licensing with strict end-use review; approvals can be politically constrained.
Channel: Direct commercial / G2G
Fielded & proven
Established · 5 operators
In service since 2022. Status: active.
Lifecycle cost (est.)
$375M – $525M
Acquisition is only ~30% of lifecycle cost — operating & support dominate over ~25 yrs. Rough 2.5–3.5× the unit price.
Interoperability
Derived guidance from public data — export regime by country of origin, lifecycle from the GAO ~30% acquisition rule. Verify eligibility, pricing and offsets with the manufacturer and your acquisition authority.
Full specifications
Performance
Speed, range, altitude and engagement capability.
- Max speed (Mach)
Maximum speed as a multiple of the speed of sound. Mach 2+ is typical for air-superiority fighters.
- 3 Mach Stronger than 34% of air-defense systems
- Engagement range
Maximum distance at which an air-defense system can intercept targets. Higher covers more airspace.
- 40 km Stronger than 45% of air-defense systems
- Engagement altitude
Maximum target altitude the system can reach.
- 20,000 m Stronger than 52% of air-defense systems
- Simultaneous targets
Number of targets the system can engage at once. Higher resists saturation attacks.
- 8 Stronger than 56% of air-defense systems
Firepower
Armament, payload and guidance.
- Main armament
Primary weapon: main gun, cannon or missile type.
- IRIS-T interceptor missile
- Warhead
Warhead mass. Heavier generally means larger effect radius, at the cost of range.
- 11 kg Stronger than 20% of air-defense systems
- Warhead type
Blast-fragmentation, shaped charge (HEAT), penetrator, thermobaric or nuclear-capable.
- Fragmentation
- Guidance
How the weapon finds its target: inertial, GPS/GLONASS, active/semi-active radar, infrared, laser, TV, wire.
- Imaging infrared homing
Sensors & avionics
Radar, sensor suite and datalinks.
- Radar
Primary radar. AESA (active electronically scanned array) is the current state of the art.
- TRML-4D AESA radar
- Radar range
Published detection range against a typical fighter-sized target. Higher sees first.
- 250 km Stronger than 70% of air-defense systems
- Datalink
Network connectivity: Link 16, MADL, national datalinks. Enables cooperative engagement.
- NATO Link 16-compatible network
Program
Cost, production scale and operators.
- Unit cost
Approximate flyaway/unit cost where public. Defense pricing varies hugely by contract, offsets and configuration. Lower is cheaper.
- $150,000,000 Stronger than 54% of air-defense systems
- Operator countries
Number of countries operating the system. More operators means broader support ecosystem.
- 5 Stronger than 71% of air-defense systems
