Pratt & Whitney has secured a nearly $1.3 billion undefinitized contracts to supply F135 engine spare parts for the global F-35 Lightning II fleet during fiscal year 2026.

Announced in a July 31, 2026, press release by parent company RTX Corporation, the Indefinite Delivery, Indefinite Quantity (IDIQ) award funds initial spare parts, deployable spare packages, depot lay-ins, and associated support equipment across all three variants of the combat Military-Aircraft.

Global sustainment and fleet readiness

The F135 sustainment enterprise currently supports operations at 42 bases and 13 ships worldwide. With more than 1,500 production engines delivered to date, the propulsion system is operated by 20 allied nations.

“Ensuring the F135 remains mission-ready is critical to the success of the F-35 enterprise,” stated Chris Johnson, Vice President of Pratt & Whitney’s F135 Program. “This contract will help strengthen our global sustainment network to ensure operators around the world can continue to rely on the F135’s unmatched performance.”

Modernization and contracting context

Pratt & Whitney plans to leverage this established sustainment network to deploy the F135 Engine Core Upgrade (ECU). The ECU has been selected as the Propulsion modernization solution for the F-35, designed to enhance fleet readiness and provide long-term capability.

While the RTX announcement did not explicitly name the awarding agency, defense contracting for the F135 propulsion system is primarily managed by the U.S. Department of Defense (DoD) Naval Air Systems Command (NAVAIR), according to reporting by Dow Jones Newswires.

We note that undefinitized contracts allow contractors to begin work before all terms and prices are finalized, a mechanism often utilized by the DoD to prevent delays in critical supply chains. Securing spare parts funding for fiscal year 2026 ensures that the expanding global footprint of the F-35 will not outpace the logistical support required to keep the aircraft operational. As the F135 Engine Core Upgrade transitions from development to deployment, maintaining a robust baseline sustainment network will be essential for integrating the modernized components across international operators.

GKN Aerospace has delivered the flight-ready wings, fins, and control surfaces for Brontanax, the United Kingdom’s first sovereign Collaborative Combat Aircraft (CCA) prototype. The delivery, announced on July 29, 2026, marks a critical manufacturing milestone for the BAE Systems-led uncrewed fighter, which is scheduled to make its first flight in 2027.

According to a press release from GKN Aerospace, the components were engineered and manufactured at the company’s Cowes facility on the Isle of Wight before being integrated at the BAE Systems assembly site in Warton, Lancashire. Brontanax is designed to fulfill the UK Ministry of Defence (MoD) requirement for the “Storm Fighter” program, an initiative aimed at fielding autonomous military aircraft to operate alongside crewed platforms like the Eurofighter Typhoon.

Manufacturing and program timeline

The structural components for Brontanax were produced at a GKN Aerospace facility that holds 125 years of aerospace manufacturing history. The project, which began in 2022 as a collaboration between BAE Systems and the Royal Air Force (RAF), required rapid prototyping and integration to meet the program’s compressed schedule.

“This is the latest example of GKN Aerospace’s ability to turn complex, clean-sheet designs into flight-ready reality at an unprecedented pace. By combining our advanced engineering with cutting-edge manufacturing, we are actively shaping the future of next-generation combat air power for the UK and our global allies,” said Rupert Dix, Senior Vice President of Defence at GKN Aerospace.

Mark Wilson, Head of Autonomous Collaborative Platforms at BAE Systems, credited GKN Aerospace’s industrial agility for delivering the high-quality structures within the required timeframe. The broader development effort has involved more than 500 BAE Systems employees and over 75 large companies and small-to-medium enterprises across the British aerospace sector.

Following the component integration, BAE Systems officially unveiled the Brontanax prototype at the Farnborough International Air-Shows on July 22, 2026. Defense News reported that the aircraft is targeting an entry into operational service by 2030, following its initial flight and operational concept demonstrations in 2027.

Strategic role of the Storm Fighter program

Brontanax is positioned as the physical answer to the MoD’s Storm Fighter requirement. The uncrewed aircraft is designed to provide electronic warfare and precision strike capabilities, adding combat mass to the RAF fleet at a lower cost while keeping human crews out of direct threat environments.

On July 1, 2026, the UK government confirmed a £300 million commitment to the Storm Fighter program within its Defence Investment Plan. UK Defence Secretary Wes Streeting highlighted this funding during the Farnborough unveiling.

“Built at BAE Systems in Warton by British engineers, backed by British businesses large and small, this aircraft demonstrates that the UK has the skills, the technology and the determination to lead the world in combat air power. We’re investing £300 million in our Storm Fighter programme to develop an autonomous combat aircraft here in the UK,” Streeting said.

Simon Barnes, Group Managing Director for BAE Systems’ Air Sector, told National Defense Magazine that the scheduled 2027 flight will serve as a primary proof of concept. The test-flights program aims to demonstrate that a large uncrewed combat platform can safely operate in UK airspace and begin fulfilling the operational roles envisioned by the RAF.

The unveiling of Brontanax at the 2026 Farnborough International Airshow highlights a broader industry pivot toward uncrewed teaming platforms. With competitors like the General Atomics FQ-42A Dark Merlin, the Boeing MQ-28 Ghost Bat, and the Anduril FQ-44A Fury also commanding attention, the global CCA market is becoming highly contested. We view the rapid prototyping of Brontanax as a necessary step for the UK aerospace sector to maintain sovereign design and manufacturing capabilities. Proving this technology in 2027 will be critical for the UK to remain competitive in the sixth-generation combat air landscape, particularly as the manned fighter element of the Global Combat Air Programme (GCAP) matures.

Airbus Helicopters delivered the first NH90 Standard 2 helicopter to the French Armament General Directorate (DGA) on July 30, 2026, introducing a specialized tactical transport variant designed specifically for special operations forces.

In a press release issued Thursday, the manufacturer confirmed the handover took place at its facility in Marignane, France. The aircraft will be operationally based in Pau, France, with the French Army Aviation. The delivery marks the first of 18 Standard 2 airframes ordered by France, with the remaining fleet scheduled for completion by mid-2029.

Technical upgrades for special operations

The NH90 Standard 2 builds upon the existing NH90 Tactical Transport Helicopter (TTH) platform by integrating equipment tailored for degraded visual environments and complex mission profiles. The modifications are designed to support operations in hostile or low-visibility conditions.

Key technical upgrades include the integration of the Safran Euroflir 410 D electro-optical system (EOS) and a new digital map generator. The cabin configuration has been altered to include a station for a third crew member and enlarged rear sliding windows to accommodate self-protection guns.

The variant also includes provisions for the Direct Aperture System (DAS), a technology currently under development to improve flight visibility in challenging conditions such as snow, dust, and fog. These sensor systems integrate directly with the Thales TopOwl helmet to enhance crew situational awareness during low-level and night operations.

Program expansion and international orders

The NATO Helicopter Management Agency (NAHEMA) initially ordered the NH90 Standard 2 program from the NHIndustries consortium in 2020. The customer base expanded in December 2025 when Spain placed an order for 31 helicopters in a similar configuration.

“We are honoured to deliver this NH90 Standard 2 to the French armed forces. This new standard builds upon the proven capabilities of the NH90 TTH with new breakthrough features designed specifically for special forces,” said Matthieu Louvot, CEO of Airbus Helicopters.

Louvot noted that Spain’s participation in developing the situational awareness features indicates the new standard is positioned to become a benchmark for special forces aviation units globally.

AirPro News analysis

The delivery of the NH90 Standard 2 represents a critical milestone for the NHIndustries consortium, which has faced scrutiny in recent years over NH90 availability rates, supply chain bottlenecks, and maintenance costs among various European operators. By successfully fielding a highly specialized variant tailored for the demanding requirements of French special forces, we view this as a stabilizing achievement for the broader NH90 program. The addition of Spain’s 31-aircraft order in late 2025 further solidifies the production backlog and spreads the development costs of the advanced sensor integration across multiple NATO partners, potentially making the Standard 2 upgrade path more attractive to other current NH90 operators.
