What threat profile justifies the exo-atmospheric procurement?

Patriot PAC-3 and IRIS-T SLM cover the atmospheric domain up to approximately 40 km intercept altitude. They are effective against Iskander-M (SRBM, ~500 km), Kinzhal (aero-ballistic, ~2,000 km), and cruise missiles of the Kalibr and Kh-101 types — systems Russia has employed at scale against Ukraine since 2022.

On 21 November 2024, Russia employed the Oreshnik in combat for the first time, striking Dnipro. The Oreshnik is a road-mobile IRBM/MRBM, likely an RS-26 Rubezh derivative, MIRV-capable, operating at the endoatmospheric/exo-atmospheric boundary. Available assessments characterise the 21 November 2024 engagement as the first documented combat use of MIRVs. In December 2025, Russia deployed Oreshnik systems to Belarus, assessed location Krichev-6 airfield — range geometry places central European population centres within reach.

Patriot PAC-3 and IRIS-T SLM have no confirmed effectiveness against the Oreshnik. The NATO IAMD Policy Paper of February 2025 states: Russia conducts salvo attacks from all azimuths and at all altitudes, ranging from micro-UAVs to ballistic and hypersonic systems. The IISS mid-2025 assessment notes: until Arrow 3 IOC on 3 December 2025, the only exo-atmospheric midcourse intercept capability within NATO was American — THAAD and Aegis Ashore.

The German government has classified the threat assessment underpinning the Arrow 3 procurement as VS-NfD with a 30-year restriction period. This corresponds to the standard classification for documents containing tactical parameters of foreign systems and own capability gaps. Practical consequence: the procurement rationale is not subject to external review.

Arrow 3 — system architecture and operational record

Arrow 3 is the uppermost tier of Israel's multi-layer air defence, developed by IAI (MLM Division) in cooperation with the US Missile Defense Agency and Boeing. The system uses a hit-to-kill kinetic interceptor without warhead, engaging targets during the midcourse phase outside the Earth's atmosphere. Intercept altitude: above 100 km. System range: up to 2,400 km. Exo-atmospheric intercept geometry effectively eliminates the risk of warhead detonation — conventional or CBRN — over populated areas.

System components: EL/M-2084 Multipurpose Radar (IAI Elta) for detection and tracking; Golden Citron Battle Management Center; Hazelnut Tree Launch Control System (Elbit Systems). Each battery: four launchers, six ready-to-fire interceptors each — 24 ready-to-fire missiles per battery at IOC.

Operational record: On 13/14 April 2024, Arrow 3 defeated the majority of an Iranian salvo attack comprising 120 ballistic missiles. On 1 October 2024, a second Iranian attack of 180 ballistic missiles followed — Arrow 3 again achieved high intercept rates. A portion of missiles struck Nevatim and Tel Nof air bases; available reporting indicates Israel allowed certain trajectories through after personnel and aircraft had been evacuated. No Western European IAMD system has comparable high-intensity operational experience.

Contract structure and procurement chronology

March 2022: German interest in Arrow 3 signalled (Scholz/Bennett). June 2023: Bundestag approves approximately EUR 4 billion. 17 August 2023: US State Department grants Foreign Military Sale approval — a prerequisite, as Arrow 3 is an Israeli-American co-development programme subject to US export controls. 23 November 2023: Initial contract ~USD 3.5 billion signed (Tel Aviv).

3 December 2025: IOC Arrow Weapon System Germany (AWS-G), Holzdorf/Schönewalde Air Base, ~75 km south of Berlin — first Arrow 3 deployment outside Israel. 18 December 2025: Bundestag approves contract expansion ~USD 3.1 billion. Total volume: ~USD 6.5 billion. Serial production of Arrow 3 interceptors for Germany is running in parallel with IDF emergency orders following the 2024/2025 conflicts.

Site disposition to FOC 2030: Holzdorf (centre, IOC achieved), Schleswig-Holstein (north, planning underway), Bavaria (south, site undecided). Coverage geometry is designed to protect large parts of central Europe — Poland, Czech Republic, Baltic states — but actual reach depends on system configuration, trajectory, and data-link connectivity. Integration into NATO Air Command Ramstein improves sensor picture and reaction times but does not fully compensate for range constraints at individual battery sites.

Arrow 3 in the ESSI architecture — role and limits

ESSI was founded by Germany in October 2022; 24 states are members. Layer architecture: IRIS-T SLM (short/medium), Patriot PAC-3 and SAMP/T (long), Arrow 3 (exo-atmospheric). Arrow 3 is the only non-American component in the exo-atmospheric tier.

Structural constraint: the large majority of ESSI's 24 members procure only the lower layers — IRIS-T SLM and Patriot. The pool of states capable of financing or operating Arrow 3 remains extremely narrow for the foreseeable future. The procurement precedent functions as a reference model for future decision-makers, not as a completed pan-European standardisation.

NATO integration: AWS-G is embedded in NATO Air Command Ramstein and connected to NATO command-and-control architecture. Technical and procedural harmonisation to NATO STANAGs is a constitutive condition of operational capability. NATO Deputy Secretary General Geoană stated in October 2023: ESSI strengthens NATO IAMD and demonstrates the value of allied burden-sharing. The distinction between ESSI as a national procurement format and NATO as the operational framework is fluid in operational reality.

France and Italy are not members of ESSI. France characterises ESSI as an initiative that prioritises American and Israeli system technology over European alternatives. The French armaments directorate DGA stated that ESSI-preferred systems do not adequately meet operational requirements for connectivity and integrated command. The Franco-Italian SAMP/T (Aster 30, MBDA) — operationally proven in Ukraine and across NATO — was not incorporated into the ESSI architecture.

Arrow 3 is a US-Israeli co-development product. Every subsequent European purchaser requires US export approval. Then-Israeli Defence Minister Gallant stated in 2023: Arrow 3 will be supplied only to countries respecting Israeli interests. An initiative declared a European shield remains entirely dependent, in its uppermost tier, on the political goodwill of Washington and Tel Aviv. This dual conditionality is not formally anchored in the NATO treaty framework or in any European defence institution.

Arrow 3 capability limits

With 24 ready-to-fire missiles per battery at IOC, intercept capacity against coordinated salvo attacks with MIRV systems is limited. The Oreshnik disperses multiple warheads on re-entry; each warhead potentially requires a separate interceptor — interceptor exhaustion is a real operational risk.

Manoeuvring Reentry Vehicles (MaRV) and hypersonic glide vehicles represent a boundary case for Arrow 3 in its current configuration. They operate at altitudes and with manoeuvre profiles that complicate intercept geometry. Electronic jamming of the EL/M-2084 radar is a Russian option; effectiveness against the specific system design cannot be publicly assessed.

These constraints account for the procurement planning for Arrow 4. IAI CEO Boaz Levy confirmed in July 2025 that Arrow 4 is approaching operational readiness. Explicit design against hypersonic threats: extended interceptor manoeuvre profile, AI-assisted radar tracking, higher response speed. German Air Defense Commander Colonel Dennis Kruger stated on 4 December 2025 to the Jerusalem Post: Germany has committed to Arrow 4 and 5. IAMD cooperation horizon: 15 to 20 years.

Complementary Israeli systems: operational relevance

Heron TP (IAI/Airbus DS Airborne Solutions): MALE RPAS, leased since 2016, operational in German airspace since May 2024, based at TaktLwG 51 "Immelmann", Schleswig-Jagel Air Base. First guided munitions delivered December 2024. Endurance 27 h, SATCOM, EO/IR/laser sensor suite IAI/Tamam M-19HD. First armed RPAS capability of the Bundeswehr. In the IAMD context: TEL suppression in the forward area reduces the intercept load on the air defence system.

Litening 5 (Rafael Advanced Defense Systems): 90 targeting pods for the Eurofighter Typhoon, ~EUR 358 million. Moving Target Indication, Thermal Imaging, range >100 km. Precision weapons enabler; without the targeting pod, the Eurofighter's ground attack capability — CAS, SEAD support, Strike — is significantly degraded.

PULS/EuroPULS (Elbit Systems/KNDS Deutschland): Multiple rocket system, ~EUR 65 million, trilateral with the Netherlands. Production in Germany planned. Permanently integrates Israeli system competence into the European defence industrial base.

Industrial entanglement: extent and risks

TKMS and Elbit Systems agreed a strategic partnership for autonomous maritime platforms in 2025: TKMS provides platform and propulsion, Elbit the sensor and electronics suite for USV and UUV. In February 2026, Elbit Cyclone opened the first production line for GRP underwater structural components for submarines in Israel — in cooperation with TKMS, representing the first transfer of core German submarine manufacturing competence to Israel. For Israel, this constitutes an industrial capability gain in the underwater domain. For Germany, the risk is a non-reciprocal technology outflow: structural manufacturing expertise built up in German shipyards over decades is being replicated in Israel without a comparable technology transfer in the reverse direction being documented.

Israeli defence exports 2024: record ~USD 14.8 billion. 2025: >USD 19 billion (IMOD, ILA Berlin 2026), driven primarily by Arrow 3 expansion contracts with Germany. Germany supplies ~30 percent of Israeli defence imports — second only to the United States. The dependency structure is bidirectional: Germany requires Israeli system technology for its IAMD architecture; Israel requires German capital flow for its defence export balance and IDF production capacity.

Assessment

The cooperation is structurally resilient to political pressure. The partial embargo episode of summer 2025 did not interrupt the supply chain; the Arrow 3 delivery deadline of December 2025 was met.

The operational record of Arrow 3 — Iranian salvo attacks of April and October 2024 — is purchase-decisive for European procurers. It demonstrates system function under high-intensity conditions but does not directly translate to performance against Russian threat profiles. Oreshnik MIRV defeat, Russian electronic countermeasures, and salvo scenarios of greater complexity than the Iranian context are not covered by combat data.

France's SAMP/T argument contains an operational dimension beyond industrial interest: the availability of a European-developed, European-controlled system in the intermediate tier is a real sovereignty option that the ESSI architecture decision has structurally weakened. Whether SAMP/T NG can close the exo-atmospheric gap in the medium term remains open; the pace of Arrow 3 procurement narrows the decision space for European alternatives in practice.

Germany has, through the Arrow 3/ESSI architecture decision, accepted a trilateral USA–Israel–Germany conditionality framework that generates operational dependencies outside the NATO treaty framework. Whether this dependency structure rests on an explicit strategic calculation or emerged as a by-product of procurement cycles remains an open question.
