Turkish Aerospace Industries (TUSAŞ) is accelerating the deployment of its T625 GÖKBEY utility helicopter, transitioning from initial deliveries to the General Command of the Gendarmerie into broader service with the Turkish Land Forces Command and international partners.

Following the delivery of the fourth GÖKBEY to the Gendarmerie on August 25, 2025, the manufacturer has expanded the platform’s operational footprint. A second production batch of 57 airframes, ordered in July 2025, is now feeding deliveries to multiple branches of the Turkish security apparatus, supporting the national objective of a fully independent defense industry.

Domestic fleet expansion

The GÖKBEY program, initiated on June 26, 2013, under a contract with the Presidency of Defence Industries (SSB), reached a steady production cadence throughout 2024 and 2025. The General Command of the Gendarmerie received its first unit on October 29, 2024, followed by subsequent deliveries in December 2024, January 14, 2025, and August 25, 2025.

In a press release marking the fourth delivery, Turkish Aerospace Industries highlighted the strategic intent behind the program:

Designed and manufactured with Turkish Aerospace’s national engineering capabilities, GÖKBEY continues to contribute to the vision of a fully independent defense industry by enhancing the operational power of our security forces.

The platform’s user base expanded on April 30, 2026, when the Turkish Land Forces Command received its first T625 GÖKBEY. According to reporting by Janes, this delivery is part of a larger 57-unit order intended for the national armed forces, gendarmerie, and coast guard. Turkish Aerospace Industries plans to deliver more than 20 helicopters to various domestic institutions by the end of 2026.

Civilian and parapublic applications are also advancing. Helis.com reported on April 6, 2026, that an air ambulance variant is nearing service entry. The Turkish Ministry of Health is expected to receive three of these specialized helicopters by late 2026.

Technical specifications and export agreements

The T625 GÖKBEY is a multi-role platform with a maximum take-off weight of 6,050 kilograms and a capacity for 12 passengers. A critical milestone for the program occurred on April 19, 2023, when the helicopter completed its first test flight powered by the domestically produced TEI-TS1400 turboshaft engine, developed by TUSAŞ Engine Industries (TEI).

The integration of a domestic powerplant has facilitated international marketing efforts. On February 10, 2026, Turkey and Saudi Arabia signed a memorandum of understanding to jointly produce the GÖKBEY helicopter in Saudi Arabia. Turkish Minute reported that this agreement marks the first major international industrial partnership for the platform.

AirPro News analysis

We view the T625 GÖKBEY program as a cornerstone of Türkiye’s strategy to eliminate reliance on foreign aerospace suppliers. The successful integration of the TEI-TS1400 engine is the most consequential technical achievement of the program. By removing foreign-sourced critical components, Turkish Aerospace Industries bypasses potential export controls and end-user restrictions that have historically complicated defense sales. The joint production memorandum with Saudi Arabia demonstrates the immediate commercial viability of this strategy, positioning the GÖKBEY as a competitive alternative in the global medium-utility helicopter market.

The Boeing Co. has secured a sole-source indefinite-delivery/indefinite-quantity (IDIQ) contract with a ceiling of $131.23 billion to support the F-15 Eagle Crest program through the next decade.

Announced in a U.S. Department of War contract release on August 24, 2026, the agreement establishes a comprehensive framework for aircraft production, modernization, and sustainment of the F-15 Eagle Weapon System. The contract is designed to ensure operational readiness for the U.S. Air Force, the Air National Guard, and seven allied nations operating the platform.

Scope and timeline of the F-15 Eagle Crest contract

The IDIQ contracts covers a broad spectrum of lifecycle requirements for the F-15 fleet. According to the Department of War, the scope of work includes new aircraft production, systems integration, modernization, upgrades, and retrofits. Notably, the agreement also provisions for the establishment of organic depot maintenance capabilities, which will allow military operators to maintain critical weapon system capabilities internally.

Work will be performed at Boeing facilities in St. Louis, Missouri. The initial ordering period is set to conclude on August 24, 2031. The contract includes an option to extend this ordering period by five years to August 24, 2036, with all associated work expected to be completed by August 2037.

The Air Force Life Cycle Management Center, based at Wright-Patterson Air Force Base in Ohio, is the contracting activity managing the award. At the time of the award, $343,740 in Fiscal 2026 research, development, test, and evaluation funds were obligated.

International reach and Foreign Military Sales

Beyond domestic U.S. military branches, the contract serves as the primary vehicle for international sustainment and procurement of the F-15 Eagle Crest. The Department of War confirmed that the contract involves Foreign Military Sales (FMS) to Japan, Israel, Saudi Arabia, South Korea, Singapore, Indonesia, and Poland.

As a sole-source acquisition, the award cements Boeing as the exclusive provider for the platform’s comprehensive lifecycle needs across these global operators, streamlining the procurement process for allied nations seeking to upgrade or maintain their existing F-15 fleets.

AirPro News analysis

While a $131.23 billion ceiling is an exceptionally high figure, we note that IDIQ ceilings represent the maximum potential value of all orders placed over the contract’s lifespan, rather than a guaranteed payout. However, setting the ceiling this high signals the Department of War’s definitive commitment to operating the F-15 Eagle Weapon System well into the 2040s, operating in tandem with fifth- and sixth-generation tactical aircraft. The specific inclusion of funding to establish organic depot maintenance capabilities is a critical detail, indicating a strategic shift toward ensuring the Air Force can independently sustain the F-15 fleet in the later stages of its service life.

Sikorsky has designated Prague-based Česká letecká servisní, a.s. (ČLS) as its first authorized European Union distribution center for Black Hawk helicopters parts, establishing a localized supply chain for the continent’s growing fleet.

Announced in an August 24, 2026, press release by parent company Lockheed Martin, the agreement aims to reduce support response times and improve parts availability for European operators. More than 150 Black Hawk helicopters currently operate within the European Union, primarily conducting emergency response, security, and mission-critical operations.

Expanding European support infrastructure

The partnerships with ČLS provides Sikorsky with a centralized logistics hub within the European Union regulatory and customs zone. Rich Benton, vice president and general manager at Sikorsky, stated that the company is focused on supporting operator readiness as the regional fleet expands.

“By working alongside ČLS, we are strengthening our service footprint in the European Union and ensuring timely parts delivery for Black Hawk helicopters,” Benton said.

For ČLS, the authorization represents a major expansion of its maintenance and logistics portfolio. Monika Kowalczykova, CEO of ČLS, noted that the appointment validates the company’s expertise in helicopter platform modernization and after-sales support. The distribution center will support multiple variants operating in the region, including the Sikorsky UH-60M, Sikorsky UH-60A/L, and Sikorsky S-70 models.

Regional fleet growth and the FIREHAWK program

The distribution agreement coincides with broader efforts by Sikorsky to deepen its industrial presence in Central Europe. Sikorsky, ČLS, Poland-based PZL Mielec, and United Rotorcraft are currently collaborating to launch the Sikorsky S-70 FIREHAWK helicopter program for the Czech Republic. This initiative targets the specialized aerial firefighting market, leveraging the Black Hawk airframe for rapid water delivery and initial attack capabilities.

Demand for the Black Hawk platform continues to grow among European operators outside the immediate European Union bloc as well. On the same day the ČLS agreement was announced, the U.S. State Department approved a potential Foreign Military Sale to Norway for 21 Sikorsky UH-60M Black Hawk helicopters. According to reporting by Aviation Week, the proposed Norwegian acquisition carries an estimated value of $2.3 billion, further expanding the footprint of the aircraft type on the continent.

AirPro News analysis

We view the selection of a Prague-based distribution center as a strategic necessity for Sikorsky given the increasing density of Black Hawk operators in Europe. Relying on transatlantic supply chains for critical rotorcraft components introduces logistical friction, particularly for operators engaged in time-sensitive emergency response and national security missions. By positioning parts within the European Union, Sikorsky mitigates customs delays and shipping bottlenecks. The concurrent push for the Sikorsky S-70 FIREHAWK in the Czech Republic and the potential $2.3 billion sale to Norway indicate that Lockheed Martin is aggressively positioning the Black Hawk family to capture European defense and civil defense budgets as nations recapitalize their aging rotorcraft fleets.
