ASELSAN and the Secretariat of Defence Industries (SSB) have signed an additional €1.47 billion contract for ongoing serial-production projects, taking the publicly announced value of major air defence agreements between the two sides beyond €5 billion since September 2025.
ASELSAN disclosed the €1,470,500,012.38 agreement through Turkiye's Public Disclosure Platform (KAP) on 10 July. The announcement did not identify the systems covered, the quantities ordered or a delivery schedule.
The disclosure describes the agreement as an addition to programmes already in serial production, indicating an expansion of existing orders rather than a separate development project or the procurement of a newly introduced system.
However, the limited disclosure does not indicate whether the contract covers missiles, launchers, gun systems, radars, electro-optical sensors, command-and-control infrastructure or a combination of these elements.
The latest agreement follows a series of major contracts between ASELSAN and the Secretariat of Defence Industries.
In September 2025, the two sides signed a €1.65 billion air defence procurement contract, with deliveries scheduled between 2027 and 2031. A further €1.122 billion in serial-production agreements was announced in November, covering deliveries between 2027 and 2030.
ASELSAN received another €780 million air defence contract on 16 June 2026, with deliveries planned between 2028 and 2032. Including the latest agreement, the publicly announced value of these contracts has exceeded €5.02 billion since September 2025.
Although the latest disclosure does not refer directly to ÇELİKKUBBE, often referred to in English as Steel Dome, the continued expansion of serial production supports the broader development of Turkiye's layered and networked air defence structure.
Steel Dome is not a single weapon system. It is designed as a system of systems connecting sensors, command-and-control infrastructure and weapons operating at different ranges and altitudes.
ASELSAN's air defence portfolio includes systems such as KORKUT, GÖKER and GÖKBERK for close-range threats, the HİSAR family for short- and medium-range engagements, and SİPER for the upper layer. Radars, electro-optical sensors and communications systems provide detection, tracking, identification and data distribution across the architecture.
HAKİM, ASELSAN's national air command-and-control system, provides the higher-level coordination required to generate and distribute a common air picture and connect available sensors with suitable effectors.
The operational value of the new orders will therefore depend not only on the number of individual systems delivered, but also on how they increase geographic coverage, engagement capacity, network resilience and the density of available interceptors.
Without system quantities and delivery dates, the agreement's immediate effect on Turkiye's air defence readiness cannot yet be measured. The cumulative value of the contracts nevertheless indicates that Steel Dome is moving beyond system development and initial induction towards sustained production and wider deployment.
