ASELSAN and ROKETSAN have signed a €1.234 billion agreement for air-defence subsystems, adding another major industrial commitment to Türkiye’s rapid expansion of its domestic air and missile defence capacity. The size of the contract is significant in its own right, but it also illustrates how Türkiye is moving from developing individual national systems towards building the industrial depth required to produce an integrated air-defence architecture at scale.
ASELSAN disclosed the agreement through Türkiye’s Public Disclosure Platform, KAP, on 23 September. The filing states that the contract with ROKETSAN covers the procurement of subsystems for air-defence systems and has a total value of €1,234,210,000, while ASELSAN expects the agreement to have a positive impact on company revenues.
The disclosure is notable for what it does not say as well as for its value. ASELSAN has not identified the individual systems involved, the quantities to be produced, the delivery timetable or the ultimate procurement programme, which means the contract should not automatically be attributed to a particular missile family or to the Steel Dome programme as a whole.
The industrial context is nevertheless clear. ASELSAN and ROKETSAN are central participants in Türkiye’s expanding air-defence ecosystem, which includes sensors, command-and-control systems, electronic warfare, guns and missiles intended to address threats ranging from small unmanned aircraft to cruise missiles, combat aircraft and ballistic missiles. Both companies are also involved in systems associated with the country’s wider effort to create a networked, layered national air-defence architecture.
ASELSAN provides much of the radar, sensor, command-and-control and electronic architecture required to detect, classify and engage aerial threats. ROKETSAN has developed and industrialised several missile and effector families, while the two companies cooperate on programmes including elements of the Hisar air-defence family and the longer-range Siper architecture.
This division of labour makes the €1.23 billion agreement particularly interesting from an industrial perspective. A modern air-defence system is not defined by the interceptor alone, because radars, seekers, datalinks, command systems, launchers, electronic protection and software must all be produced in sufficient quantities and integrated into a common architecture.
The challenge facing most European countries today is therefore no longer principally whether an advanced interceptor or radar can be designed. The more difficult question is whether the complete industrial system behind it can manufacture sensors, effectors and critical subsystems in the volumes required for sustained operations while continuing to replenish stocks during a prolonged conflict.
Türkiye has spent years building a comparatively broad national defence-industrial base, and the latest contract suggests that the emphasis is increasingly moving towards scale. Large internal supply agreements between leading national defence companies create the production visibility that allows manufacturers to expand capacity, secure specialist suppliers and invest in tooling, test facilities and workforce before higher output is required.
There is also an export dimension. Turkish defence companies have expanded rapidly across the Middle East, Asia, Africa and parts of Europe, and a mature domestic air-defence architecture creates opportunities to offer customers combinations of radar, command-and-control and weapons rather than individual products. This is particularly relevant as demand for ground-based air defence has increased sharply following operational experience in Ukraine and the Middle East.
The contract should still be interpreted with some caution. It is an agreement between two Turkish defence companies rather than a newly disclosed €1.23 billion direct government order, and the public filing provides too little information to determine how much of the value represents entirely new production rather than subcontracted work within existing procurement programmes.
Even with that qualification, the scale is substantial. Agreements of this size between prime defence manufacturers normally indicate a production horizon extending well beyond a limited batch of equipment and underline the amount of industrial capacity now being committed to air and missile defence.
The wider European comparison is relevant. Across NATO, manufacturers are expanding Patriot, IRIS-T, NASAMS, SAMP/T, CAMM and other air-defence production while governments attempt to rebuild inventories that were designed for much lower consumption rates. Türkiye is pursuing the same strategic objective through an industrial model in which a comparatively large share of the sensor, command and weapon chain is produced domestically.
That model provides Ankara with advantages that extend beyond military availability. Domestic control over a larger part of the supply chain reduces exposure to export restrictions, gives Turkish industry greater freedom to modify systems and enables the government to use defence exports as an instrument of wider security and foreign policy.
The €1.234 billion ASELSAN–ROKETSAN agreement is therefore important not because it reveals a new air-defence system; at present, it does not. Its significance lies in the industrial scale behind systems that Türkiye has already spent years developing, and in the transition from possessing national air-defence technology to being able to manufacture an increasingly complete air-defence ecosystem in volume.
For European defence planners, that distinction deserves attention. The strategic competition in air defence is increasingly becoming a competition not only over range, radar performance or interceptor technology, but over which countries possess supply chains capable of producing complete systems quickly, repeatedly and in sufficient numbers for a long war.
