Lockheed Martin F-35 Deliveries Resume Amid TR-3 Upgrade Challenges
72 F-35 jets delivered after delays, as $2 trillion program faces certification hurdles and financial penalties over TR-3 upgrade issues.
Lockheed Martin’s F-35 Deliveries Amidst TR-3 Upgrade Delays: A Comprehensive Analysis
Lockheed Martin has delivered 72 F-35 fighter jets to the U.S. government as of May 1, 2025, following extended delays stemming from issues with the Technology Refresh 3 (TR-3) upgrade. The delivery marks a partial recovery from a year-long pause in shipments that began in mid-2023, caused by software instability and hardware integration challenges. The TR-3 package, designed to modernize the F-35’s computing systems, is critical to supporting future Block 4 capabilities, which include advanced sensors and expanded weapons options.
Despite the resumed deliveries, the program remains under scrutiny. The Department of Defense (DoD) has withheld millions in payments per aircraft, reflecting concerns about the aircraft’s readiness for combat. The F-35 program, which accounts for nearly a third of Lockheed Martin’s annual revenue, is at a pivotal juncture as it balances technological ambition with operational reliability and fiscal accountability.
Background Information
The F-35 Lightning II, developed under the Joint Strike Fighter (JSF) program, is the U.S. Department of Defense’s most ambitious and expensive aircraft project. Initiated in the 1990s, the program aimed to replace aging fleets across multiple military branches with a single, versatile platform. Lockheed Martin was selected as the prime contractor in 2001, developing three variants: the F-35A for conventional takeoff and landing, the F-35B for short takeoff/vertical landing, and the F-35C for carrier-based operations.
International collaboration has been a hallmark of the program. Partner nations such as the United Kingdom, Italy, and Australia have contributed to development and production, with global suppliers manufacturing key components. This has not only distributed costs but also strengthened geopolitical alliances through shared defense capabilities.
The TR-3 upgrade is central to the F-35’s future. It introduces a next-generation integrated core processor, improved cockpit displays, and an open-architecture software framework. These changes are foundational for the subsequent Block 4 enhancements, which will significantly expand the aircraft’s mission capabilities, including integration of new weapons and advanced electronic warfare tools.
TR-3 and Block 4: Strategic Importance
TR-3 is more than a routine upgrade, it is the technological backbone for future enhancements. Without it, the F-35 cannot support the upcoming Block 4 capabilities, which are essential for maintaining superiority against evolving threats. These include hypersonic weapons, advanced integrated air defenses, and the growing use of unmanned systems in combat.
It also introduces artificial intelligence features to assist pilots in mission planning and threat assessment. The Department of Defense and Lockheed Martin have emphasized the importance of TR-3 as a prerequisite for these capabilities.
However, delays in TR-3 have ripple effects. Without certification, new aircraft are limited to training roles, and existing fleets cannot be upgraded. This stalls progress on pilot training, base deployments, and integration with allied forces, particularly in Europe where several NATO members await their deliveries.
Key Facts and Data
As of May 1, 2025, Lockheed Martin has delivered 72 F-35 jets to the U.S. government. This follows a significant backlog caused by TR-3 delays, during which aircraft were completed but not accepted due to software and hardware issues. In 2024, only 110 jets were delivered, well below the production capacity of 156 units per year. The company aims to deliver between 170 and 190 units in 2025 as it clears the parked inventory.
The financial implications are substantial. The Department of Defense initially withheld $5 million per aircraft due to the delays, later reducing this to $3.8 million in January 2025 after Lockheed showed progress on TR-3. These funds are expected to be released gradually through 2026, contingent on full combat certification of the upgrade.
Overall, the F-35 program’s projected lifetime cost has now surpassed $2 trillion, according to multiple government and industry sources. This figure includes $422 billion for procurement and $1.58 trillion for sustainment over the aircraft’s projected service life, which has been extended to 2088. Inflation adjustments account for nearly $1 trillion of the total cost.

Recent Developments
The TR-3 upgrade has faced multiple technical hurdles. Software instability and hardware shortages, particularly in the core processor supplied by L3Harris, have delayed certification. Although Lockheed Martin declared the system “stabilized” in June 2025, the Department of Defense has not yet approved it for combat operations. As a result, aircraft delivered since July 2024 are restricted to training missions.
Lockheed’s facilities have also struggled with storage for undelivered jets. The Fort Worth assembly plant ran out of parking space, prompting concerns from the Government Accountability Office about infrastructure constraints. Additionally, the testing fleet, comprised of older aircraft, has suffered from spare parts shortages, further delaying the evaluation of TR-3 and Block 4 capabilities.
International deliveries have been affected as well. Denmark, Belgium, and Italy have experienced delays, and the United Kingdom has adjusted its procurement strategy by switching from F-35Bs to F-35As to meet nuclear certification requirements. These shifts underscore the global impact of the TR-3 delays and the interconnected nature of the program.
Expert Opinions
Lockheed Martin executives have acknowledged the challenges while emphasizing progress. CEO James Taiclet noted that while TR-3 is not yet fully certified, the company has achieved significant milestones. Vice President J.R. McDonald described the upgrade as being “very close” to combat readiness and highlighted its importance for allied deterrence, particularly in Europe.
Military officials have echoed these sentiments but remain cautious. Lt. Gen. Mike Schmidt, who oversees the F-35 program, defended the phased delivery approach, stressing the need for stable and maintainable aircraft. Gen. James Hecker of U.S. Air Forces Europe warned that unresolved TR-3 issues continue to affect training and base deployment timelines.
Independent oversight bodies have raised concerns about the program’s structure. The Government Accountability Office cited the practice of concurrency, developing and producing aircraft simultaneously, as a key factor in the program’s escalating costs and delays. It also warned that extending the service life of older platforms like the F-16 could create capability gaps if F-35 upgrades are not delivered on time.
Global and Industry Context
The U.S. Navy’s F/A-XX program and the Air Force’s Next Generation Air Dominance (NGAD) initiative reflect a shift toward sixth-generation capabilities. While Lockheed Martin remains a central player, competitors like Boeing are gaining ground with new fighter concepts and drone integration strategies.
European participation in the F-35 program remains strong. Components are manufactured across the continent, and Lockheed has outlined plans for a fully European-assembled F-35 by 2026. This industrial collaboration not only strengthens transatlantic ties but also ensures supply chain resilience amid geopolitical uncertainties.
Despite the delays, the F-35 continues to expand its global footprint. NATO allies such as Greece, Romania, and the Czech Republic have signed new contracts, and potential deals with Austria, Portugal, and Spain are under discussion. These developments highlight the aircraft’s enduring appeal despite its challenges.
Conclusion
Lockheed Martin’s delivery of 72 F-35 jets marks a significant but incomplete step toward stabilizing the program. The TR-3 upgrade remains a bottleneck, affecting both domestic and international operations. Financial penalties, infrastructure constraints, and testing delays continue to pose risks to the program’s schedule and credibility.
Looking ahead, the successful implementation of TR-3 and the rollout of Block 4 capabilities will be critical. These upgrades are essential not only for maintaining air superiority but also for preserving the program’s global partnerships. As the defense landscape evolves, the F-35 must adapt to remain a cornerstone of allied airpower.

CBP AMO Orders 10 Airbus H125 Helicopters for Fleet Expansion
CBP Air and Marine Operations contracts for 10 Airbus H125 helicopters, expanding a 30-year fleet of over 100 rotary-wing aircraft.
U.S. Customs and Border Protection Air and Marine Operations (CBP AMO) has finalized a contract to acquire 10 additional Airbus H125 helicopters, expanding a fleet modernization effort that relies heavily on the single-engine platform for border security and law enforcement missions.
In a press release issued on July 7, 2026, Airbus confirmed the agreement, which reinforces a three-decade relationship between the federal agency and the aerospace manufacturer. The new helicopters will be assembled at the Airbus Helicopters production facility in Columbus, Mississippi.
Expanding the airborne law enforcement fleet
The latest acquisition builds upon a previous order placed in August 2020, when CBP AMO contracted for 16 H125 helicopters to upgrade its aging rotary-wing assets. The agency currently operates a total fleet of more than 240 aircraft, which includes over 100 helicopters from the Airbus H120 and H125 families delivered over the past 30 years.
The H125, formerly known as the Eurocopter AS350, is utilized by CBP AMO for a variety of demanding flight profiles, including border surveillance, suspect pursuit, and general public safety operations across the United States.
Bart Reijnen, Head of the North America Region for Airbus Helicopters, stated that the expansion “underscores the long-standing collaboration” between the manufacturer and the federal agency. He added that the selection highlights the trust placed in the H125 to execute critical public safety missions under demanding conditions, with Airbus committing to provide comprehensive services to maintain mission readiness.
Virtual reality integration for pilot training
As CBP AMO increases its H125 inventory, the agency is simultaneously overhauling how it trains the personnel who fly them. In November 2025, CBP became the first federal law enforcement agency and the first branch of the U.S. Department of Homeland Security (DHS) to integrate virtual reality into its aerial training program.
According to reporting by FLYING Magazine, the agency awarded a contract to adopt an FAA-qualified Airbus H125 virtual reality flight simulator developed by Loft Dynamics. The simulator is being installed at the CBP AMO training center in Oklahoma City, where it will be used to train the agency’s roster of more than 600 pilots.
AirPro News analysis
We view CBP AMO’s continued investment in the H125 platform as a clear indicator of the agency’s preference for fleet commonality. Operating a standardized fleet of over 100 H125-family helicopters significantly reduces maintenance overhead, streamlines supply chains, and simplifies pilot transition training. Furthermore, Airbus’s strategy of assembling these aircraft in Columbus, Mississippi, likely plays a crucial role in navigating federal procurement requirements, ensuring that the European manufacturer remains highly competitive for U.S. government contracts. The parallel investment in Loft Dynamics’ VR simulators suggests the agency is preparing for a sustained, long-term operational lifespan for the H125 fleet.

EU Funds SHARP Project for Next-Gen Military Helicopter Engine
The EU allocated €25M to the SHARP consortium, 25 partners from 12 countries developing Europe’s next military helicopter engine by 2040.
The European Commission has allocated approximately €25 million through the European Defence Fund to back a multinational consortium developing the propulsion architecture for Europe’s next generation of military helicopters.
Announced on June 11, 2026, at the ILA Berlin airshow, the Sovereign High-performance Architecture for Rotorcraft Propulsion (SHARP) project brings together 25 partners from 12 European countries. According to a joint press release from Safran Helicopter Engines, MTU Aero Engines, and Avio Aero, the initiative will establish the technological foundation for the European Next Generation Helicopter Engine (ENGHE), which is targeted to enter service in 2040.
Addressing an aging military rotorcraft fleet
The SHARP initiative aligns with broader European defense goals to replace a rapidly aging fleet of military aircraft under the Next Generation Rotorcraft Capability (NGRC) and European Next Generation Rotorcraft Technologies (ENGRT) programs. The current European inventory includes approximately 1,800 transport helicopters and 600 combat helicopters, which currently average 20 years of age. By the 2040s, many of these aircraft will have been in service for over 50 years.
“In light of a continuously aging European fleet of military helicopters the need is obvious: From 2040 onwards, a large proportion of these rotorcraft will have to be replaced,” said Dr. Ottmar Pfänder, Chief Program Officer at MTU Aero Engines. “We joined forces across the continent to underline the importance of this technology program. It will further reinforce European sovereignty and strengthen the European supply chain.”
The funding will be used to develop scalable technological building blocks that can be adapted to various weight classes and mission profiles required by future European armed forces.
Collaborative framework and European sovereignty
The SHARP project builds upon the foundation of the EUropean Military Rotorcraft Engine Alliance (EURA), a 50/50 joint venture established in July 2024 between Safran Helicopter Engines and MTU Aero Engines specifically to develop the ENGHE. The consortium has now expanded to include Avio Aero, broadening the industrial base tasked with designing the new powerplant.
Safran Helicopter Engines CEO Cédric Goubet stated that the funding demonstrates Europe’s commitment to self-reliance and technological sovereignty for future military platforms, thanking the European Union and participating nations for their confidence in the consortium’s capabilities.
“SHARP marks an important milestone in the journey toward Europe’s next-generation rotorcraft engine and reinforces the value of collaboration in developing sovereign, high-performance propulsion technologies,” said Riccardo Procacci, CEO of Avio Aero. “We are proud to partner with EURA on this initiative, contributing within a fully European framework while leveraging Avio Aero’s well-established expertise and know-how.”
EURA CEO Wolfgang Gärtner confirmed that the joint venture is prepared to coordinate the multinational team to provide modern technologies to European forces.
AirPro News analysis
The €25 million European Defence Fund grant represents a critical early step in aligning Europe’s fragmented defense aerospace sector behind a single rotorcraft propulsion program. By formalizing the SHARP consortium now, the European Union is actively working to prevent the development of competing, incompatible national engine programs that have historically complicated European defense procurement and increased long-term maintenance costs. We view the inclusion of Avio Aero alongside the EURA joint venture as a strong indicator that the ENGHE program is successfully consolidating the continent’s primary propulsion manufacturers ahead of the 2040 target.
