Self-Reliance as an Argument: How Arms Embargoes Shaped Türkiye's Defense Industry

Why It Matters

Türkiye is a leading example of how export restrictions between allies can push a mid-sized power toward defense self-reliance. Turkish officials say the share of domestically produced content in defense procurement has risen from roughly 20% in the early 2000s to about 80%. That is an official, project-based figure rather than an independent audit. Whether it is read as resilience or as a hedge against partners, it now shapes NATO planning, regional balances and arms-export diplomacy.

Background

From the Johnson Letter to the 1975 Embargo

The Turkish argument for self-reliance starts in 1964. On 1964-06-05, US President Lyndon Johnson sent a letter to Prime Minister İsmet İnönü warning that US-supplied equipment could not be used in a Cyprus intervention without Washington's consent. Turkish commentators cite it as the moment Ankara concluded that wartime access to allied arms could not be assumed.

The decisive episode followed the 1974 events in Cyprus. After the coup of 1974-07-15 and Türkiye's operation of 1974-07-20 (launched under Article IV of the 1960 Treaty of Guarantee), the US Congress voted to restrict arms transfers. The embargo took effect on 1975-02-05, was eased in October 1975, and was fully lifted on 1978-09-26. Washington's stated reasoning was that US-supplied weapons had been used in breach of US law; Ankara's view is set out below.

Building Institutions

Several core institutions date from this period:

• ASELSAN (military electronics) was founded in 1975 by the Turkish Armed Forces Foundation.
• A central procurement structure was created in 1985 and later became the Undersecretariat for Defense Industries (SSM).
• In 2018 it was reorganised as the Presidency of Defense Industries (SSB), reporting directly to the Presidency.

Later Restrictions

The pattern recurred in different forms in the 2000s and 2010s. Turkish officials have said that Türkiye's requests for armed US-origin unmanned aircraft were not met, and Ankara turned to domestic development after long delays in imported systems. Three further episodes followed:

1. Operation Peace Spring (October 2019): Finland, Norway, the Netherlands, Germany, France and others announced national restrictions on arms exports to Türkiye. Canada suspended export permits, including for electro-optical sensors used on the Bayraktar TB2, and later cancelled permits.
2. F-35 programme (2019-07-17): Following delivery of the Russian S-400 air-defense system, Washington removed Türkiye from the F-35 programme, in which Turkish firms were also industrial partners.
3. CAATSA sanctions (2020-12-14): The US sanctioned the SSB and several of its officials under Section 231 of the Countering America's Adversaries Through Sanctions Act.

The Programmes

The localisation drive now covers every domain:

• Unmanned aircraft: Baykar's Bayraktar TB2 (exported widely and bought by Poland in 2021), the larger Akıncı, and the jet-powered Bayraktar Kızılelma, which first flew on 2022-12-14. TUSAŞ also builds the ANKA and Aksungur.
• Naval: The MİLGEM national corvette and frigate programme produced the first ship, TCG Heybeliada, in 2011. TCG Anadolu, a multi-purpose amphibious assault ship, entered service on 2023-04-10. Its design drew on Spain's Juan Carlos I class, so it is better read as national construction with foreign design heritage than as a wholly indigenous design.
• Air and missile defense: The HİSAR family (including HİSAR-O) and the long-range SİPER are being integrated into a layered concept called Steel Dome (Çelik Kubbe).
• Combat aircraft: KAAN, a fifth-generation fighter whose prototypes initially use US-origin engines, while a national engine is under development. Hürjet is a jet trainer and light combat aircraft.

What 'About 80%' Measures

The figure comes from Turkish officials, including the Presidency and the SSB. It is generally described as the domestic share of ongoing procurement projects, rising from about 20% two decades ago. Three caveats apply:

• It describes programmes managed by the SSB, not every item in the armed forces' inventory.
• It does not mean 80% of every component is made in Türkiye. Engines, some sensors, transmissions and specialised electronics have long been imported or co-developed.
• Methodologies for measuring localisation differ between countries, and no international body audits the Turkish figure. Treat it as an official claim, as discussed in Monitor of Nations' explainer on how domestic production reached about 80%.

Key Players & Positions

United States

The US government's stated reasons for the 2019–2020 measures concern the S-400, which Washington argued is incompatible with the F-35's security architecture and creates risks for NATO systems. Congress has also linked arms sales to wider disputes involving Greece, Cyprus and Sweden's NATO accession. After Türkiye's parliament ratified Sweden's accession in January 2024, the F-16 package moved forward.

European Allies and Canada

The 2019 restrictions were justified under national implementation of the EU Common Position on arms exports (2008/944/CFSP), citing the Syria operation and civilian-harm concerns. In the Madrid memorandum of 2022-06-28, Finland and Sweden committed to lifting their restrictions. Policy still varies between countries, so licensing rules should be checked in each jurisdiction.

NATO

NATO officials have generally described Türkiye as a major contributor. Türkiye is commonly cited as having the Alliance's second-largest armed forces by active personnel, and it hosts the Kürecik early-warning radar. Allies' concerns centre on interoperability and on the S-400.

Russia

Moscow supplied the S-400 and presents the deal as a normal commercial contract between sovereign states.

Greece, Cyprus and Armenia

Athens and the Greek Cypriot administration raise concerns about the Eastern Mediterranean balance. Yerevan has criticised Turkish drone exports to Azerbaijan. These governments argue that growing capability should be matched by restraint.

Human-Rights Bodies and UN Experts

NGOs question the use of armed drones in Syria, Libya and elsewhere. The UN Panel of Experts on Libya has reported violations of the Libya arms embargo by several external actors, including in its reporting on Türkiye. Ankara rejects wrongdoing and says its support was provided at the request of Libya's internationally recognised government under a bilateral agreement signed on 2019-11-27.

Türkiye's Position

• Self-reliance is a lesson, not a preference. According to the Presidency of Defense Industries (SSB) and the Presidency, the 1975 embargo and later restrictions showed that critical capabilities cannot depend on a single foreign supplier. Ankara cites the Johnson letter and the embargo as formative precedents.
• Legal basis in alliance and UN law. Ankara argues that building national capacity follows from Article 3 of the Washington Treaty, which commits parties to 'maintain and develop their individual and collective capacity to resist armed attack', and from the inherent right of self-defence under Article 51 of the UN Charter. In October 2019, the Turkish Ministry of Foreign Affairs described national export restrictions by several allies as inconsistent with the spirit of alliance.
• The industry supports NATO. The Ministry of National Defense and the Presidency say domestic systems add deterrence on NATO's south-eastern flank, in the Black Sea (where Türkiye applies the 1936 Montreux Convention, see Montreux Article 19 in practice) and in the Eastern Mediterranean. Ankara points to Alliance partners who buy or co-produce Turkish systems; see Interstate Journal on Türkiye in NATO.
• Counter-terrorism at the source. Ankara states that unmanned and precision systems reduce risk to personnel and civilians in operations against the PKK/YPG (designated a terrorist organization by Türkiye, the US, NATO and the EU), DAESH and FETÖ; see Euphrates Shield, Olive Branch, Peace Spring and Spring Shield compared and the Fact Check on the YPG–PKK link.
• The S-400 was a last resort. Turkish officials say Ankara sought Patriot systems from allies on acceptable terms for years before buying the S-400, and that Türkiye proposed a technical working group on interoperability. Ankara links the long-term answer to its national air-defense programmes and to open channels with allies. It also says the Terror-Free Türkiye process is intended to reduce the security burden over time.
