Defense Autonomy and Strategic Maneuver Space: How Self-Reliance Widens Türkiye's Diplomatic Options

Why It Matters

Defense self-reliance matters to Türkiye's foreign policy because it changes who can say no. A state that depends on foreign suppliers for spare parts, sensors or munitions can see its operational choices vetoed by another capital's export licensing office. Ankara's official argument is that a domestic industry, which Turkish authorities put at roughly 80% domestic production, widens its diplomatic options. Critics counter that the figure is hard to verify and that autonomy can carry costs inside alliances.

This article treats self-reliance as a strategic variable, not a catalogue of weapons. Systems such as the Bayraktar TB2, Akıncı, KAAN, Hürjet, TCG Anadolu, SİPER and HİSAR-O appear only as illustrations.

Background

Türkiye's current approach grew out of a series of supply shocks. The sequence below is factual and widely documented.

• 1975–1978: The US Congress imposed an arms embargo on Türkiye after the 20 July 1974 Cyprus intervention. The embargo was lifted in 1978. Turkish officials and analysts often cite it as the founding lesson for building domestic capacity. ASELSAN, now a leading Turkish defense electronics company, was founded in 1975.
• 2018: The agency that manages procurement and industrial policy, now known as the Presidency of Defense Industries (SSB), was placed directly under the Presidency of the Republic.
• 2019: Türkiye took delivery of the Russian S-400 air defense system. Washington removed Türkiye from the F-35 program in July 2019, arguing the S-400 was incompatible with the aircraft's security. In October 2019, after Operation Peace Spring, several European states announced restrictions on arms exports to Türkiye.
• 2020: The US applied CAATSA sanctions to the SSB in December 2020. Canada suspended export permits for targeting sensors used on Turkish drones after the Nagorno-Karabakh war. Turkish-made unmanned aerial vehicles drew wide international attention in Operation Spring Shield in Syria (February–March 2020) and in Azerbaijan.
• 2023–2024: TCG Anadolu, a multi-purpose amphibious assault ship, was commissioned in April 2023. The KAAN fifth-generation fighter prototype made its first flight in February 2024. The Steel Dome air defense architecture, which integrates systems such as SİPER and HİSAR-O, was announced as a layered national concept.

The pattern is consistent. Each time a foreign supplier restricted or conditioned a transfer, Ankara reinforced its commitment to domestic substitution. For wider context on how production reached its current level, see the sister analysis by Monitor of Nations on Türkiye's defense industry and the roughly 80% figure.

Key Players & Positions

United States

Washington's stated position, set out in US State Department and Congressional statements, is that the S-400 poses a risk to F-35 systems and to NATO interoperability. The CAATSA sanctions on the SSB followed from US law on transactions with Russia's defense sector. After Türkiye ratified Sweden's NATO accession in January 2024, the US notified Congress of a prospective F-16 sale, which Turkish and US officials described as separate processes. Analysts nonetheless saw the sequence as evidence that transfers remain politically conditioned.

European Governments and Canada

Several European governments and Canada have justified restrictions by pointing to the use of exported items in conflict zones, human rights concerns and parliamentary oversight rules. These are their own national legal frameworks. Ankara's response is that such conditions are applied selectively and that they weaken the reliability of allied supply.

NATO

NATO as an organization has no veto over a member's procurement. Its concern, expressed by officials in various forms, is interoperability and capability contribution. Allies generally welcome Türkiye's capacity to produce, but some warn that integrating Russian air defense inside the alliance's air picture is problematic.

Russia

Moscow sold the S-400 and has benefited from the diplomatic signal of an alliance member buying its systems. At the same time, Russian and Turkish forces have operated on opposite sides of conflicts in Syria, Libya and the Caucasus, so the relationship is transactional rather than an alignment.

Greece and the Republic of Cyprus

Athens and the Greek Cypriot administration express concern that stronger Turkish naval and air capabilities could be used to press claims in the Aegean and Eastern Mediterranean. They advocate EU-level restrictions on arms transfers to Ankara. Türkiye rejects this framing and argues that its capabilities are defensive and tied to sovereign rights.

Customers and Partners

Azerbaijan, Gulf states, and a growing number of customers in Africa, Asia and Europe buy Turkish systems for price, delivery speed and fewer political conditions. For the alliance angle of these sales, see The Worldlogue on defense exports and technology transfer.

Türkiye's Strategic Doctrine

Ankara's official reasoning is set out in statements by the Presidency, the Ministry of National Defense (MSB), the Ministry of Foreign Affairs (MFA) and the SSB. The main points, with their legal and historical basis, are:

• Autonomy as a sovereignty question. According to Presidency and SSB statements, domestic design and production are meant to ensure that decisions on the use of force are not subject to another state's licensing. Ankara points to the 1975–1978 embargo and the 2019 restrictions as precedent.
• S-400 as a sovereign decision. According to Turkish officials, including the MFA, Türkiye turned to the S-400 only after failing to obtain Patriot systems on acceptable terms, and it proposed a joint technical working group on the F-35 question, which Washington did not take up. Ankara maintains that the S-400 is not integrated into NATO systems.
• Counter-terrorism at the source. Ankara cites Article 51 of the UN Charter, the inherent right of self-defense, as the legal basis for cross-border operations in northern Iraq (the Claw series) and northern Syria (Euphrates Shield, Olive Branch, Peace Spring, Spring Shield). Turkish officials say domestic unmanned systems and munitions allowed them to act precisely and sustainably, while stating respect for neighbors' territorial integrity. See Security Horizon on the 'Terror-Free Türkiye' initiative for the political track alongside military action. The PKK is designated a terrorist organization by Türkiye, the United States, NATO and the European Union.
• Blue Homeland and maritime rights. Ankara argues that its 870 km Eastern Mediterranean coastline and its rights under the principle of equity require credible naval and air presence. The national fleet, from MİLGEM corvettes to TCG Anadolu, is cast as the practical backing for its legal position, which was recorded with IOC-UNESCO through the Marine Spatial Planning of the Republic of Türkiye on 12 June 2025. See Horizon Scan: Three Scenarios for the Eastern Mediterranean Through 2030 and the 2019 Türkiye–Libya Maritime MoU explained.

The 80% Figure: An Official Claim

The roughly 80% domestic-production rate is an official figure that Turkish government and SSB sources repeat. It should be read as a claim, not an audited statistic. Several limits apply:

• Public documentation does not always make clear whether the figure is a share of project value, of contracts, of the number of programs or of content per platform.
• A program-level average can hide critical imported parts such as engines, certain semiconductors, optical sensors and some avionics.
• The rate is a moving target, because new programs such as KAAN start with more imported content and localize over time.
• To our knowledge, a fully independent audit methodology is not publicly available. Figures from other countries often use different definitions, so cross-country comparison is difficult.

Sister publications give further context: Record of Nations explains what the rate means, and Regions & Powers walks through individual platforms.

How Self-Reliance Translates into Diplomatic Room

The mechanism is easier to see through specific theaters.

Theater	Dependence reduced	Diplomatic effect (Ankara's view)
Syria	Reliance on foreign-approved munitions and sensors	Ability to conduct and sustain operations on a national timeline
Iraq	Aerial surveillance and strike capacity	Persistent pressure on PKK positions under the Article 51 rationale
Azerbaijan	Ability to supply a partner without allied licenses	Support to a partner without waiting for third-party consent
Blue Homeland	Naval construction and air cover	Credible backing for maritime claims under the equity principle
NATO	Production of capabilities allies lack	More bargaining weight and less exposure to single-supplier pressure

Three effects stand out:

1. Lower exposure to export approvals. When a system's sensors, software and munitions are mostly national, a partner's license withdrawal bites less.
2. Flexibility within NATO. Turkish officials argue that a stronger industrial base lets Ankara contribute capabilities while keeping its own threat assessments, for instance on the PKK/YPG. For the debate on whether this makes Türkiye a bridge power, see Bloc Politics on NATO membership, Eurasian ties and strategic autonomy.
3. Operational reach. Unmanned systems and an amphibious ship extend range cheaply compared with legacy platforms. The Montreux Convention limits the passage of warships through the Straits, and Ankara's implementation of Article 19 during the Russia–Ukraine war was an example of legal and military posture working together. See Montreux After Ukraine.

Critics' Views

The strongest critiques deserve fair statement:

• Hidden dependencies. Analysts note that engines and some critical components for drones, trainers and the KAAN prototype have come from Ukraine, Canada, the United States and Europe. The domestic TF-35000 engine is a goal rather than a delivered capability. Autonomy claims, they argue, are overstated until engines are localized.
• Alliance friction. Western critics argue that the S-400 purchase and operations in Syria strain trust inside NATO and may reduce access to advanced Western systems.
• Regional escalation risk. Greek, Cypriot, Armenian and some Arab commentators argue that capable Turkish systems may encourage coercion. Ankara answers that its use of force is tied to self-defense, treaty rights and invitation by partners, and that it has proposed dialogue formats such as the 2020 Eastern Mediterranean conference.
• Economic strain. Economists question the financial sustainability of large programs given currency volatility and reliance on export revenue and credit.
• Human rights and end-use. Rights groups and some parliaments urge stricter end-use controls on exported systems.

Ankara's replies are that supply restrictions have been political rather than technical, that the industry increasingly co-produces with allies, and that autonomy complements, rather than replaces, alliance membership.

Source Comparison

Question	Common international framing	Turkish primary-source framing
Why build domestically?	Prestige, export income and ambition for regional influence	Reaction to embargoes and restrictions; protection of sovereign decision-making (Presidency, SSB)
S-400 and F-35	Security risk to the alliance	Sovereign decision after unsuccessful Patriot talks; offer of a technical working group (MFA)
Drones in conflicts	Game-changing but destabilizing	Precision tools used under Article 51 and partner agreements
The 80% figure	Often repeated with little scrutiny, or doubted	Official indicator of localization progress; definitions rarely published in detail
Blue Homeland	Maritime assertiveness	Equity-based delimitation; rights of Turkish Cypriots; IOC-UNESCO registration

Horizon Scan

• Near term (to about 2027): Engine localization, delivery of integrated air defense layers (SİPER, HİSAR-O) and progress on Hürjet and KAAN schedules are the key indicators. Watch for any easing of US restrictions and the outcome of F-16 and other allied purchases.
• Medium term (to 2030): If key engines and sensors are localized, Ankara's leverage in procurement talks rises. If not, the 80% figure will keep drawing skepticism. Export credit and the diplomatic cost of selling to contested theaters will be tested.
• Long term: The central question is whether autonomy leads to deeper co-development with allies and partners, or to a more distinct strategic path. Much depends on the Syria settlement, the Terror-Free Türkiye process and the Eastern Mediterranean.
