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 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.
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 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. 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.
“The F-35 program’s cost now exceeds $2 trillion, driven largely by sustainment and lifecycle extensions.” — Government Accountability Office 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.
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.
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.
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.

Firehawk Aerospace Expands Rocket Motor Production in Mississippi Facility
Firehawk Aerospace acquires a DCMA-rated facility in Mississippi to boost production of solid rocket motors using 3D-printing technology.
This article is based on an official press release from Firehawk Aerospace.
On December 19, 2025, Firehawk Aerospace announced a significant expansion of its manufacturing capabilities with the acquisition of a specialized defense facility in Crawford, Mississippi. The Dallas-based defense technology company has secured a 20-year lease on the 636-acre site, which was formerly operated by Nammo Talley.
This acquisition marks a strategic pivot for Firehawk as it moves to address critical shortages in the U.S. defense supply chain. By taking over a facility that is already rated by the Defense Contract Management Agency (DCMA), the company aims to bypass the lengthy construction and certification timelines typically associated with greenfield defense projects. The site will serve as a hub for the full-system integration of solid rocket motors (SRMs), complementing the company’s existing R&D operations in Texas and energetics production in Oklahoma.
The Crawford facility is located in Lowndes County within Mississippi’s “Golden Triangle” region. According to the company’s announcement, the site is a “turnkey” defense asset designed specifically for handling high-grade explosives and munitions. The infrastructure includes assembly bays protected by one-foot-thick concrete walls and safety “blowout” walls designed to contain accidental detonations.
Because the facility was previously used by Nammo Defense Systems for the high-volume assembly of shoulder-launched munitions, such as the M72 LAW and SMAW systems, it retains the necessary regulatory certifications to allow for rapid operational ramp-up. Firehawk Aerospace CEO Will Edwards emphasized the urgency of this expansion in a statement regarding the deal.
“This acquisition strengthens Firehawk’s ability to address one of the nation’s most urgent defense challenges: rebuilding munition inventories that have been drawn down faster than they can be replaced.”
, Will Edwards, Co-founder and CEO of Firehawk Aerospace
The acquisition comes at a time when the Western defense industrial base is grappling with a severe shortage of solid rocket motors, which power critical systems like the Javelin, Stinger, and GMLRS missiles. Traditional manufacturing methods, which involve casting propellant in large batches that take weeks to cure, have created production bottlenecks.
Firehawk Aerospace intends to disrupt this model by utilizing proprietary 3D-printing technology to manufacture propellant grains. According to the press release, this additive manufacturing approach reduces production times from weeks to hours. The company has explicitly stated that the new Mississippi facility is being designed to achieve a production tempo of “thousands of rockets per month,” a significant increase over legacy industry standards. “While the current industrial base is built to produce thousands of rockets per year, we are building this site… to operate at a much higher production tempo… designing for throughput measured in thousands per month, not years.”
, Will Edwards, CEO
The expansion is expected to bring skilled jobs to the Golden Triangle region, which is increasingly becoming a hub for aerospace and defense activity. Mississippi Governor Tate Reeves welcomed the investments, noting the dual benefits of economic growth and national security support.
“Their acquisition in Crawford will bring skilled jobs to the region while directly contributing to the production capacity our nation needs.”
, Tate Reeves, Governor of Mississippi
From R&D to Mass Production: This acquisition signals Firehawk’s transition from a development-focused startup to a volume manufacturer. By securing a pre-rated facility, Firehawk has effectively shaved 2–3 years off its timeline, the period typically required to build and certify a new explosives handling site. This speed is critical given the current geopolitical demand for tactical munitions.
Supply Chain Decentralization: The move also highlights a strategy of decentralization. By distributing operations across Texas (R&D), Oklahoma (Energetics), and now Mississippi (Integration), Firehawk is building a supply chain that may prove more resilient than centralized legacy models. This geographic diversity also allows the company to tap into distinct labor markets and state-level incentives, such as Mississippi’s aerospace initiatives.

Frequently Asked Questions
A DCMA (Defense Contract Management Agency) rating verifies that a facility meets strict Department of Defense quality and safety standards. Acquiring a pre-rated facility allows Firehawk to begin production much faster than if they had to build and certify a new site from scratch.
Traditional solid rocket motors are cast in large batches, a process that requires weeks for the propellant to cure. Firehawk uses 3D-printing technology to print propellant grains, which allows for custom geometries and reduces the manufacturing time to mere hours.
The facility was formerly operated by Nammo Talley (now Nammo Defense Systems) for the assembly of shoulder-launched munitions, including the M72 LAW and SMAW systems.Sources

20 Years of the F-22 Raptor Operational Capability and Upgrades
Lockheed Martin celebrates 20 years of the F-22 Raptor’s operational service, highlighting its stealth, combat roles, readiness challenges, and modernization.
Lockheed Martin has launched a campaign commemorating the 20th anniversary of the F-22 Raptor achieving Initial Operational Capability (IOC). In December 2005, the 27th Fighter Squadron at Langley Air Force Base in Virginia became the first unit to field the fifth-generation fighter, marking a significant shift in global air superiority.
According to the manufacturer’s announcement, the aircraft continues to define the benchmark for modern air combat. In a statement regarding the milestone, Lockheed Martin emphasized the platform’s enduring relevance:
“The F-22 Raptor sets the global standard for capability, readiness, and mission success.”
While the airframe was designed in the 1990s and first flew in 1997, the F-22 remains a central pillar of U.S. air power. The fleet, which consists of approximately 185 remaining aircraft out of the 195 originally built, has evolved from a pure air superiority fighter into a multi-role platform capable of ground strikes and strategic deterrence.
Since its operational debut, the F-22 has maintained a reputation for dominance, primarily established through high-end military aircraft exercises rather than direct air-to-air combat against manned aircraft.
Data from the U.S. Air Force and independent observers highlights the discrepancy between the Raptor’s exercise performance and its real-world combat engagements. During the 2006 Northern Edge exercise, its first major test after becoming operational, the F-22 reportedly achieved a 108-to-0 kill ratio against simulated adversaries flying F-15s, F-16s, and F/A-18s.
Despite this lethality in training, the aircraft’s combat record is distinct. The F-22 made its combat debut in September 2014 during Operation Inherent Resolve, conducting ground strikes against ISIS targets in Syria. To date, the aircraft has zero confirmed kills against manned enemy aircraft. Its sole air-to-air victory occurred in February 2023, when an F-22 utilized an AIM-9X Sidewinder missile to down a high-altitude Chinese surveillance balloon off the coast of South Carolina.
The primary driver of the F-22’s longevity is its low observable technology. Defense analysts estimate the Raptor’s Radar Cross Section (RCS) to be approximately 0.0001 square meters, roughly the size of a steel marble. This makes it significantly stealthier than the F-35 Lightning II and orders of magnitude harder to detect than foreign competitors like the Russian Su-57 or the Chinese J-20.
While Lockheed Martin’s anniversary campaign highlights “readiness” as a key pillar of the F-22’s legacy, recent Air Force data suggests a more complex reality regarding the fleet’s health. We note that maintaining the world’s premier stealth fighter comes at a steep logistical cost. According to data published by Air & Space Forces Magazine regarding Fiscal Year 2024, the F-22’s mission capable (MC) rate dropped to approximately 40%. This figure represents a decline from roughly 52% in the previous fiscal year and indicates that, at any given time, fewer than half of the Raptors in the inventory are flyable and combat-ready.
This low readiness rate is largely attributed to the fragility of the aircraft’s stealth coatings and the aging avionics of the older airframes. The Air Force has previously attempted to retire 32 older “Block 20” F-22s used for training to divert funds toward newer programs, though Congress has blocked these efforts to preserve fleet numbers. The contrast between the jet’s theoretical dominance and its logistical availability remains a critical challenge for planners.
Contrary to earlier projections that might have seen the F-22 retired in the 2030s, the Air Force is investing heavily to keep the platform viable until the Next Generation Air Dominance (NGAD) fighter comes online.
In 2021, the Air Force awarded Lockheed Martin a $10.9 billion contract for the Advanced Raptor Enhancement and Sustainment (ARES) program. This decade-long modernization effort aims to update the fleet’s hardware and software.
According to budget documents for Fiscal Year 2026, the “Viability” upgrade package includes several key enhancements:
These investments suggest that while the F-22 is celebrating its past 20 years, the Air Force intends to rely on its capabilities well into the next decade.

U.S. Navy Zero-G Helmet System Completes Critical Design Review
Collins Elbit Vision Systems completes design review for the Zero-G Helmet Display, reducing pilot weight load and enhancing safety for Navy aircraft.
This article is based on an official press release from Collins Elbit Vision Systems (RTX).
Collins Elbit Vision Systems (CEVS), a joint venture between RTX’s Collins Aerospace and Elbit Systems of America, has officially announced the completion of the Critical Design Review (CDR) for the Zero-G Helmet Mounted Display System+ (HMDS+). This milestone, finalized on December 12, 2025, marks a pivotal step in the U.S. Navy’s Improved Joint Helmet-Mounted Cueing System (IJHMCS) program.
The successful CDR effectively freezes the system’s design, confirming that the helmet meets the Navy’s rigorous requirements for safety, performance, and platform integration. With the design locked, the program now transitions into the airworthiness testing and integration phase, bringing the system closer to deployment aboard the F/A-18E/F Super Hornet and EA-18G Growler fleets.
According to the press release, the Zero-G HMDS+ is engineered to address long-standing physiological challenges faced by naval aviators while introducing “6th-generation” digital capabilities to existing 4.5-generation aircraft.
The Zero-G HMDS+ represents a significant departure from legacy analog systems. While previous iterations required pilots to physically attach heavy Night Vision Goggles (NVGs) for low-light operations, the new system integrates digital night vision directly into the visor. This integration streamlines cockpit operations and reduces the physical burden on the aircrew.
A primary driver for the Zero-G’s development is the reduction of head-borne weight. High-G maneuvers in fighter aircraft place immense strain on a pilot’s neck and spine, a hazard exacerbated by heavy, unbalanced legacy helmets. CEVS reports that the Zero-G system is more than 25 percent lighter than current market alternatives. Its name is derived from its optimized center of gravity, designed to minimize fatigue and long-term injury risks.
Capt. Joseph Kamara, the U.S. Navy Program Manager for Naval Aircrew Systems (PMA-202), emphasized the safety implications of the new design in a statement:
“Aircrew health and safety is our number one priority. The Zero-G being integrated through our IJHMCS program promises to relieve aircrew of neck and back strain and greatly improve ejection safety.”
Beyond ergonomics, the helmet utilizes a binocular waveguide display system. Unlike monocular reticles used in older models, this technology projects high-definition color symbology and video into both eyes, creating a fully immersive 3D view of the battlespace. The system is capable of “sensor fusion at the edge,” processing mission data and weapon information directly on the helmet to act as a primary flight instrument. Luke Savoie, President and CEO of Elbit Systems of America, highlighted the strategic necessity of this upgrade:
“Zero-G is providing sensor fusion at the edge… As fighter aircraft level-up, the HMDs of those systems need to as well.”
The Zero-G HMDS+ program has moved rapidly since CEVS was awarded a $16 million contract by the U.S. Navy in September 2023 for development and test support. Following the successful CDR in December 2025, the program is scheduled to undergo flight testing and Avionics integration throughout 2026 and 2027.
The U.S. Navy projects Initial Operational Capability (IOC) for the system in 2027. Once fielded, it is expected to equip aviators across the entire fleet of U.S. Navy and Royal Australian Air Force Super Hornets and Growlers, totaling more than 750 aircraft.
The completion of the CDR signals a critical maturity point for the Navy’s effort to modernize the human-machine interface in its tactical fleet. While much industry attention is focused on future platforms like NGAD (Next Generation Air Dominance), the Zero-G program illustrates the military’s commitment to maintaining the lethality and survivability of its existing backbone fleet.
By adapting technology originally matured for the F-35 Gen III helmet, CEVS is effectively retrofitting advanced situational awareness tools onto older airframes. This approach not only extends the combat relevance of the Super Hornet but also addresses the acute retention issue of pilot physical health. The shift to digital night vision and balanced weight distribution suggests that the Navy views pilot longevity as a critical component of fleet readiness.
