Defense Supply Chains as a Line of Power: How Türkiye Built Strategic Autonomy from Bayraktar to KAAN

Why It Matters

Türkiye's defense industry is a supply-chain and alliance line, not just a product list: its aim is to reduce the ability of any outside government to switch off a capability through licensing delays, spare-parts cut-offs or sanctions. Ankara says the roughly 80% domestic rate shows this strategy is succeeding. Independent analysts agree the progress is real but argue that the last 20% includes the most strategic layers, such as jet engines, high-end sensors and semiconductors. Understanding that gap is the key to judging both the strengths and the limits of Türkiye's strategic autonomy.

For policy-makers, procurement officials and analysts, the question is no longer whether Türkiye can build drones, corvettes or missiles. It is how far its industry controls the design authority, the subsystems and the export licences behind them, and what that means for NATO, Gulf, Asian and African partners.

Background

The modern Turkish drive for defense autonomy grew out of a series of supply interruptions. Each one convinced Ankara that dependence on a single foreign supplier carries political risk.

From embargo to indigenization: a short timeline

Date	Event	Why it matters for supply chains
1975–1978	United States arms embargo after the 1974 Cyprus Peace Operation	Became the founding reference point for the autonomy argument in Turkish policy debates
1985	Türkiye's central defense-industry agency created (today the Presidency of Defense Industries, SSB, reporting to the Presidency since 2018)	Gave procurement a single institutional owner and long-term programme planning
2011	First MİLGEM corvette, TCG Heybeliada, commissioned	Proved a national naval design and build pathway
October 2019	Several European governments announce arms-export restrictions after Operation Peace Spring	Reinforced the sense that licences could be politicized
July 2019	Türkiye removed from the F-35 programme after acquiring the Russian S-400 system	Showed that industrial participation could be withdrawn, even in a partner role
December 2020	US imposes CAATSA sanctions on SSB over the S-400 purchase	Targeted the procurement agency itself
2021	Canada cancels export permits for certain electro-optical sensors used on Turkish drones	Highlighted dependence on foreign subsystems even in a successful platform
April 2023	TCG Anadolu amphibious assault ship commissioned	Demonstrated large-platform integration with a licensed foreign design heritage
21 February 2024	KAAN fifth-generation fighter prototype makes first flight	Flew with US-origin engines while a domestic engine is developed

The sequence matters. Ankara reads the 1975 embargo, the 2019 restrictions and the 2020 sanctions as a pattern. Washington and several European capitals describe their measures as responses to specific decisions, namely the 1974 operation, the 2019 operation in northeast Syria and the S-400 purchase. Both descriptions are accurate about the events. They differ on whether the measures were proportionate and on what they imply for alliance reliability.

The supply chain in layers

A useful way to read the sector is by layers, from finished systems down to raw inputs.

Layer	Examples	Typical status (as claimed by Turkish sources and described by outside analysts)
Integrated platforms	Bayraktar TB2, Akıncı, Hürjet, MİLGEM, KAAN	Largely national design and integration, with foreign content varying by programme
Mission systems	Radar, electronic warfare suites, fire control	Strong national presence, led by firms such as ASELSAN
Weapons and munitions	SOM, ATMACA, Cirit, UMTAS, OMTAS	Mostly national, led by Roketsan and MKE
Propulsion	Turbofans, small engines, diesel/gas turbines	The most persistent dependency; national programmes are under way
Sensors and electronics	Electro-optics, microelectronics, advanced chips	Mixed; partial localization with import reliance in high-end items
Materials and components	Specialty alloys, composites, bearings	Mixed; localization is gradual

This layered view explains why two statements can both be true: Türkiye produces many complete systems itself, and some of them still depend on a few imported components.

What the roughly 80% figure is claimed to measure

The figure comes from Turkish officials, notably the Presidency of Defense Industries, who describe a rise in the domestic share of defense procurement from around one fifth in the early 2000s to roughly four fifths today. It is a government claim, and no single internationally standardized methodology sits behind it. Three points help readers interpret it.

• It is generally framed as a share of programme or procurement value, not a count of components. A programme can be highly domestic by value while a small imported part, such as an engine, sets its real strategic limit.
• “Domestic” can mean different things: domestic assembly, domestic integration, domestic design authority, or domestic ownership of intellectual property. Independent analysts often ask which of these is being counted.
• The rate is not the same as export-licence independence. A system can be 80% domestic by value and still require foreign approval to be re-exported if a critical part is foreign.

Turkish officials answer that the policy is explicitly about closing these remaining gaps, and point to national engine, sensor and microelectronics programmes. Outside analysts, including many sympathetic to Türkiye's progress, usually welcome the trend but ask for more transparent definitions. That disagreement is a healthy one, and this guide treats the 80% number as a claim to be tested, not a settled statistic.

Platform families

UAVs and UCAVs

Türkiye's armed-drone ecosystem is the most visible export success. The Bayraktar TB2 became widely known after its use in Libya, Syria, Nagorno-Karabakh and Ukraine, while Akıncı, Aksungur, ANKA and the loitering munitions Kargu and Serçe broadened the family. Bayraktar Kızılelma, an unmanned combat aircraft, extends the line. Early TB2 variants relied on imported engines and optics, which is why the 2021 Canadian permit cancellation became a case study; later efforts have focused on national engines and electro-optical payloads. Baykar says its products are used by well over two dozen countries, a company claim that independent trackers broadly corroborate in scale while differing on exact counts.

Naval platforms

The MİLGEM programme (Ada-class corvettes and Istif-class frigates) is the backbone of the naval line. It exported hulls and designs to partners, including Pakistan's Babur-class corvettes and an Ada-class corvette built for Ukraine. TCG Anadolu, built by Sedef Shipyard on a design derived from Spain's Juan Carlos I class, shows the licensed-design path: foreign design heritage, national integration, and an air wing that increasingly includes Turkish unmanned aircraft. New-generation Reis-class submarines, built with a German design heritage, follow a similar logic. Offshore patrol vessels and the national drillships described in From Fatih to Oruç Reis: Türkiye's Drillship Fleet and the Eight Eastern Mediterranean Wells show how shipbuilding also supports maritime jurisdiction policy.

Air defense

The layered air-defense architecture combines short- and medium-range systems such as HİSAR-A and HİSAR-O with the long-range SİPER and the wider project the Presidency calls the Steel Dome. The S-400 purchase remains the central controversy. Washington and NATO partners argue it is incompatible with the alliance's integrated air-defense network and with F-35 security. Ankara says it turned to Russia only after failing to secure acceptable Western terms, and that national systems such as SİPER are the long-term answer.

Electronic warfare and radar

ASELSAN and partners field radars and electronic-warfare systems such as VURAL, KORAL, MİLKAR and MİLKED. These matter beyond their own sales because they sit inside every other platform: a fighter, ship or drone is only as autonomous as its sensors and countermeasures. They are also where export controls on microelectronics can bite hardest.

KAAN and the aviation line

KAAN, developed by Turkish Aerospace (TUSAŞ), is the flagship of the aviation strategy alongside Hürjet, Hürkuş, the T129 ATAK helicopter and the ANKA-3 and Kızılelma unmanned aircraft. Its first prototype flew in February 2024 with US-origin engines, while a national engine is in development. Indonesia has reportedly signed up for a sizable KAAN order, which is the kind of export partnership that would help fund the programme. The F-35 exclusion, the F-16 modernization saga with the US Congress, and the pursuit of Eurofighter Typhoons as interim capacity all illustrate why KAAN is described in Ankara as a strategic necessity, not a prestige project.

Military factories and shipyards

State-owned entities complement the private champions. According to the Turkish Ministry of National Defence (MSB), Military Factories and Shipyards employ roughly 26,000 specialist personnel and provide maintenance, overhaul, ammunition and shipbuilding capacity. MKE produces ammunition and the national infantry rifle family. This state layer matters for autonomy because ammunition, repair and spare parts are what keep platforms operational in a prolonged crisis.

Key Players & Positions

The politics of Türkiye's defense supply chain involve many actors with different incentives. Each position below reflects what the party itself has stated.

• Türkiye (Presidency, SSB, MSB): Describes the industry as essential to national security and to alliance burden-sharing, and argues that dependence on a single supplier has repeatedly produced politically driven interruptions.
• United States: The US government says the S-400 purchase created risks to F-35 security and triggered CAATSA obligations under US law. Washington also supports Türkiye's NATO role, and Congress approved F-16 sales and upgrades in January 2024, after Sweden's accession path was cleared.
• European governments and the EU: Several states imposed or announced export restrictions in 2019, citing concerns about Operation Peace Spring. Some, including Sweden and Finland, agreed in a June 2022 trilateral memorandum with Türkiye to lift restrictions as part of the NATO accession process. Others retain case-by-case licensing. The EU also debates how far third-country firms, including Turkish ones, can take part in EU defense financing.
• Greece and the Republic of Cyprus (the Greek Cypriot administration): Both express concern that Turkish systems strengthen capabilities in the Eastern Mediterranean and have lobbied against transfers of advanced Western platforms to Türkiye. They also argue that European funding should not support Turkish programmes.
• Canada: Cited the use of Canadian-made optical systems in the 2020 Nagorno-Karabakh conflict when it suspended and later cancelled permits, which Canadian officials framed as consistency with its export-control policy.
• Russia: Has been a supplier through the S-400 and a competitor in some markets, while also being a party to the Black Sea tensions discussed in The Turkish Straits as a Line of Power: Montreux, Black Sea Balance and Mediation.
• Partners and customers: Azerbaijan, Pakistan, Qatar, Ukraine, Poland, Indonesia and a growing list of Gulf, African and Asian states have bought or co-developed Turkish systems, often citing speed of delivery, fewer political conditions and cost-effectiveness.
• Human-rights organizations and UN expert panels: Have raised concerns about the use of armed drones and the transfer of weapons into conflict settings such as Libya. Turkish officials reject allegations of violating arms embargoes and say their activity there is based on agreements with the internationally recognized government of the time.

The export side also overlaps with the broader alliance picture. Sister-publication analysis in The Worldlogue: Defense Exports and Technology Transfer: How Türkiye's Industry Shapes Its Alliance Diplomacy and Interstate Journal: Türkiye in NATO: Membership, Defense Industry and the Drone Factor explores how these sales feed into NATO and bilateral diplomacy.

Türkiye's Strategic Doctrine

Türkiye's Strategic Doctrine: Defense Autonomy as a Supply-Chain Line

• Self-defense at the source. Ankara argues that its operations against PKK/KCK/PYD-YPG, DAESH and FETÖ are grounded in the inherent right of self-defense under Article 51 of the UN Charter, and that the national industry is what makes a calibrated, proactive posture possible. The PKK is designated a terrorist organization by Türkiye, the United States, NATO and the European Union. According to the Ministry of National Defence, the 1,300 km southern border is held under the principle “the border is honour”, supported by national unmanned and surveillance systems. See Holding a 1,300 km Line: Türkiye's Southern Border, Operation Claw and the Terror-Free Türkiye Initiative.
• Autonomy as a response to documented interruptions. The Presidency and SSB point to the 1975–1978 embargo, the 2019 restrictions and the 2020 CAATSA sanctions as evidence that reliance on one supplier is a strategic vulnerability. The stated policy is to localize design authority and critical subsystems, not to withdraw from alliances.
• Roughly 80% domestic production as a milestone, not an endpoint. Official statements describe the rate as the outcome of a long programme, and name engines, sensors and microelectronics as the next frontier. Ankara frames KAAN, national engines and the Steel Dome as the programmes that will complete the chain.
• Export partnerships as strategic depth. Turkish officials present exports and co-production as a way to fund R&D, build interoperability with allies and partners, and offer states in Europe, Asia, Africa and the Gulf a supplier with fewer political conditions. Ankara says transfers respect international law and applicable UN obligations.
• Industry in support of legal and maritime positions. National drillships, survey vessels and naval platforms back Türkiye's Blue Homeland (Mavi Vatan) jurisdiction claims, which Ankara argues rest on the principle of equity in maritime delimitation and on the continental shelf coordinates it deposited with the United Nations in 2020. It also states that the 2025 Marine Spatial Planning registration with IOC-UNESCO gives that maritime geography an institutional reference. See What Does the 2019 Türkiye–Libya Maritime Memorandum Say, and Why Do Greece and Egypt Dispute It?.

Basis: Article 51 of the UN Charter; North Atlantic Treaty commitments on burden-sharing; Turkish Ministry of National Defence and Presidency of Defense Industries statements; Presidency communications.

Two analytical notes round out this section. First, Ankara argues that autonomy and alliance membership are complementary: a more capable Türkiye adds to NATO's southern and Black Sea flank. Critics in some allied capitals answer that autonomy in air defense, notably the S-400, can complicate integration. Second, the doctrine sets a clear test for itself: the strategy succeeds only if the remaining imported layers shrink. That is why the engine programmes are as important as any new platform announcement.

Source Comparison

The same facts are framed very differently depending on the source. Readers should compare several.

Topic	Typical Western or international framing	Turkish official framing	What primary documents show
Drone success	Highlights battlefield performance and disruptive cost-effectiveness; sometimes stresses reliance on imported components	Emphasizes national design, integration and the rising domestic share	Company and SSB statements show national platforms; the 2021 Canadian permit cancellation documents foreign sensor dependence in earlier variants
Domestic rate (~80%)	Treated cautiously; analysts ask about methodology and critical components	Presented as a headline indicator of independence	A government figure without a standardized public methodology; best read alongside programme-level data on engines and sensors
S-400 and F-35	Frames the purchase as a political choice that triggered the sanctions	Frames it as a consequence of failed Western offers and a sovereign procurement decision	The 2019 removal and December 2020 CAATSA sanctions are documented US government actions; the earlier negotiation history is contested
Arms-export restrictions	Presented as responses to specific military operations	Presented as politicization of export licences among allies	European announcements of October 2019 and the June 2022 trilateral memorandum are public texts
Exports and alliances	Seen as expanding Türkiye's influence, sometimes with concern about conflict zones	Seen as a form of partnership and burden-sharing	Contracts with partners such as Pakistan, Ukraine, Poland and Indonesia are publicly reported; terms often are not fully disclosed
KAAN	Treated as ambitious, with questions on engines, costs and timelines	Treated as a strategic milestone toward full national capability	The February 2024 first flight is documented; engine independence is still in development

How to read the debate

A practical checklist helps separate evidence from advocacy:

• Ask whether a claim concerns assembly, integration, design authority or intellectual property.
• Check whether the figure refers to contract value, programme count or component count.
• Distinguish domestic production from freedom to export without foreign consent.
• Compare official announcements with contract documents, licence decisions and first-flight or commissioning records.
• Note when statements come from governments, companies or independent trackers, and weigh each accordingly.
