Bell Textron and TEREM-Holding Partner on Bulgarian Air Force Helicopter Maintenance
Bell Textron Prague and TEREM-Holding establish local maintenance for Bulgarian Air Force Bell 206 fleet, enhancing operational readiness.
Bell Textron Prague and TEREM-Holding Establish Maintenance Framework for Bulgarian Air Force
We are observing a significant development in the European defense logistics sector as Bell Textron Prague, a subsidiary of Textron Inc., and TEREM-Holding EAD, a Bulgarian state-owned defense company, have officially signed a Memorandum of Understanding (MOU). Announced on November 19, 2025, this agreement establishes a framework to provide local maintenance capabilities for the Bulgarian Air-Forces’s (BAF) fleet of Bell 206 helicopters. This collaboration marks a pivotal moment for Bulgaria’s defense infrastructure, signaling a move toward greater self-sufficiency in maintaining Western-manufactured military assets.
The agreement addresses a long-standing logistical gap within the region. Historically, the maintenance of Western rotorcraft in Eastern Europe has often required shipping aircraft or components to foreign facilities, resulting in increased downtime and logistical complexity. By partnering with TEREM-Holding, Bell Textron Prague aims to localize these critical services. This strategic alignment ensures that the Bulgarian Air Force can maintain high operational readiness for its training and light transport fleet without the heavy reliance on external, cross-border support chains that characterized previous operational models.
From our perspective, this MOU is more than a simple service contract; it represents a structural shift in how legacy Western platforms are sustained in NATO’s eastern flank. The collaboration leverages the technical authority of the Original Equipment Manufacturer (OEM) while utilizing established local infrastructure. This dual approach is designed to streamline the supply chain for spare parts, engineering support, and technical oversight, ensuring the Bell 206 fleet remains airworthy and effective for years to come.
Operational Roles and Technical Scope
Under the terms of the MOU, the division of labor is clearly defined to maximize the strengths of both entities. Bell Textron Prague, serving as the European regional hub, will provide the necessary technical certifications and oversight. Specifically, they will bring their European Union Aviation Safety Agency (EASA) Part 145 (maintenance organization) and Part 21 (design and engineering) capabilities to the table. This includes the supply of genuine spare parts, access to proprietary technical data, and engineering support for heavy maintenance, retrofits, and potential modifications.
On the other side of the partnership, TEREM-Holding EAD will act as the local executor. Through its subsidiaries, likely leveraging the aviation-focused TEREM-Letets, the holding company will provide the physical facilities, hangars, and skilled personnel required to carry out the maintenance tasks. Their role is to execute the “hands-on” work under the guidance and certification umbrella provided by Bell. This structure allows for a transfer of knowledge and standards, gradually upskilling the local workforce to meet specific OEM requirements for Western airframes.
The primary objective here is to create a robust “local solution.” By embedding these capabilities within Bulgaria, the Ministry of Defense reduces the turnaround time for repairs and scheduled maintenance. We see this as a critical efficiency improvement for the BAF, which relies on these helicopters for pilot training. Keeping these assets in the air rather than in transit to foreign repair stations is essential for maintaining the pipeline of new pilots entering the force.
“We are thrilled to explore this cooperative effort between Bell and TEREM Holding Bulgaria as we provide maintenance support to the Bulgarian Air Force. Through our in-region maintenance hub, Bell Textron Prague continues to be a trusted aftermarket provider for military and commercial aircraft customers,” Vlastimil Cepicka, Manager, Bell Textron Prague.
The Bell 206 Fleet: A Cornerstone of Training
To understand the importance of this agreement, we must look at the assets involved. The Bulgarian Air Force operates a fleet of six Bell 206B-3 JetRanger III helicopters. These aircraft were acquired in 1998 and delivered between July and September 1999. For over 25 years, they have served as the primary rotary-wing trainers for the BAF. Every helicopter pilot in the Bulgarian military begins their journey in the cockpit of a Bell 206, making the reliability of this fleet paramount to the operational future of the entire air force.
Beyond basic flight training, these helicopters fulfill secondary roles that are vital to domestic security and safety. They are utilized for liaison missions, observation, and light transport duties. Furthermore, two of the units are specifically equipped with high ground-clearance skids to facilitate medical evacuation (MEDEVAC) operations. This versatility means that the fleet is not just a training tool but an active operational asset that supports civil and military objectives alike.
Despite their age, these airframes remain in active service. The longevity of the Bell 206 is well-documented, but maintaining aging airframes requires precise and consistent technical attention. This MOU suggests a commitment to extending the life of these helicopters rather than replacing them immediately. By securing a direct line of support from Bell Textron Prague, Bulgaria is effectively investing in the life-extension and modernization of these critical assets, ensuring they remain safe and effective despite decades of wear.
Strategic Context: Bridging the East-West Divide
This agreement must be viewed against the broader backdrop of Bulgaria’s defense modernization efforts. TEREM-Holding has historically specialized in the repair and maintenance of Soviet-designed equipment, such as the Mi-8, Mi-17, and Mi-24 helicopters. The transition of their workforce and facilities to accommodate Western NATO standards has been a gradual and sometimes challenging process. This partnership with Bell acts as a catalyst, accelerating the adoption of Western maintenance cultures and quality assurance protocols within a state-owned enterprise.
We can draw parallels to previous challenges faced by the Bulgarian Air Force regarding its Eurocopter AS 532 Cougar fleet. In the past, a lack of domestic maintenance capacity for the Cougars forced the military to rely on foreign contractors or the NATO Support and Procurement Agency (NSPA), often leading to logistical bottlenecks. The Bell-TEREM deal appears to be a corrective measure, applying lessons learned to avoid similar dependency issues. It represents a proactive step to build domestic competence from the ground up.
Looking ahead, this development aligns with Bulgaria’s wider integration of advanced Western platforms, such as the incoming F-16 Block 70 fighters. Developing a domestic industrial base capable of sustaining complex Western aerospace technology is a prerequisite for the long-term affordability and sovereignty of Bulgaria’s defense. By starting with the Bell 206 fleet, TEREM is laying the groundwork for a more capable, NATO-interoperable defense industry.
Conclusion
The Memorandum of Understanding between Bell Textron Prague and TEREM-Holding represents a pragmatic and strategic evolution in Bulgarian defense logistics. By localizing the maintenance of the Bell 206 fleet, the agreement ensures higher operational availability for the Bulgarian Air Force’s training wing while simultaneously upgrading the technical capabilities of the state-owned defense sector. It is a move that balances immediate operational needs with long-term industrial goals.
As we monitor the implementation of this agreement, the success of this partnership could serve as a model for future sustainment contracts in the region. If TEREM can successfully absorb the technology transfer and standards required by Bell, it opens the door for further expansion into Western platform maintenance, potentially positioning Bulgaria as a regional hub for similar services in the future.

Gripen F Completes Inaugural Flight in Linköping Sweden
Saab and the Brazilian Air Force completed the first flight of the Gripen F two-seat fighter on August 28, 2026.
Saab and the Brazilian Air Force have successfully completed the inaugural flight of the Gripen F, the two-seat variant of the Gripen E fighter, initiating the airborne test campaign for the jointly developed aircraft.
The aircraft took off from Saab’s airfield in Linköping, Sweden, on August 28, 2026. In a press release issued today, the manufacturer confirmed the milestone advances a comprehensive technology transfer program designed to deliver both pilot training and full operational combat capabilities.
Inaugural flight and test campaign
The flight commenced at 09:40 local time and lasted 40 minutes. Saab Chief Test Pilot Jakob Högberg and Brazilian Air Force Test Pilot Lieutenant Colonel Aviator Abdon de Rezende Vasconcelos operated the aircraft.
Lars Tossman, Head of Business Area Aeronautics at Saab, highlighted the collaborative effort behind the milestone.
“This first flight represents an important step forward for both Saab and the Brazilian Air Force. Seeing Gripen F take to the skies is particularly significant for all the Swedish and Brazilian teams whose years of engineering work have helped turn this aircraft into a reality. It is designed to accelerate pilot training while and enhancing operational performance in advanced combat missions,” Tossman said.
The Gripen F test program will now transition into a progressive envelope expansion phase. Saab stated that upcoming flights will clear performance limits, including speed, altitude, G-load, and angle of attack, while evaluating the tactical systems of the independent rear cockpit.
Design specifications and Brazilian procurement
The Gripen F incorporates specific design modifications to accommodate a second crew member. According to Air Data News, the two-seat variant measures 15.9 meters in length, compared to the 15.2-meter single-seat Gripen E, and has a maximum takeoff weight of 16,500 kilograms. To make room for the rear cockpit, engineers omitted the internal 27 mm Mauser BK27 cannon found on the single-seat model. Despite this change, the aircraft retains full operational combat capability and utilizes the same General Electric F414G engine.
The development of the Gripen F is heavily tied to Brazilian defense procurement. Aviation Week reports that the Brazilian Air Force ordered eight Gripen F aircraft as part of a broader 36-aircraft contract signed in 2014. Saab officially presented the first Gripen F during a rollout ceremony in Linköping on June 2, 2026. The manufacturer noted that more than 350 Brazilian engineers, technicians, and pilots have participated in training and development activities for the program.

Neura Defense Systems Rebrands as Volantyx Aerospace
Neura Defense Systems rebrands as Volantyx Aerospace to develop counter-UAS tech targeting RF-silent drone swarms.
Saint Petersburg, Florida-based Neura Defense Systems, Inc. announced on August 26, 2026, that it has rebranded as Volantyx Aerospace, Inc. to reflect its expansion from a single-product defense developer into a broader aerospace technology platform.
In a press release issued Wednesday, the company stated the original Neura Defense Systems name will be retained for its defense division and current operating business. The corporate restructuring aligns with the company’s focus on developing a distributed edge-intelligence architecture designed to counter autonomous, radio-frequency-silent drone swarms.
Addressing the RF-silent swarm-drone gap
Volantyx Aerospace is targeting a specific vulnerability in current counter-Unmanned Aircraft Systems (UAS) defense networks. Traditional detection and mitigation rely heavily on radio frequency (RF) signals, which are ineffective against pre-programmed or autonomous aircraft that do not emit such signals.
Founder and Chief Executive Officer Sam Talari explained the limitations of legacy systems in the company’s announcement, noting that the new architecture is built on the assumption that any single sensor can be degraded or absent.
An RF sensor cannot detect a signal that is not there, and a jammer cannot sever a control link that does not exist. We start from the aircraft’s physical signature instead — radar return, sound, heat, visual — and combine those into one track and one decision picture for the operator.
The company has filed 13 United States provisional patent applications covering multi-modal sensor fusion, distributed networking, cognitive command, and the detection of non-emitting aircraft. The resulting intelligence layer is designed to make decisions at the edge without cloud dependency while preserving a record of system observations.
Development timeline and market positioning
The rebranding occurs as federal investment in counter-UAS technologies accelerates. Volantyx Aerospace remains in the development stage, with its core capabilities currently undergoing hardware integration and field evaluation following initial tests in a controlled environment.
The company clarified in its release that it does not yet claim a fielded deployment, operational performance metrics, or a contract award. Volantyx Aerospace plans to begin manufacturing or supplying effectors in early 2027. The corporate name change is a structural adjustment for the Delaware corporation and does not alter existing agreements, obligations, or ownership.
AirPro News analysis
The transition from Neura Defense Systems to Volantyx Aerospace signals a strategic pivot to capture dual-use commercial and defense markets. As autonomous UAS capabilities proliferate, the reliance on RF jamming and detection is becoming a recognized vulnerability in airspace security. By focusing on multi-modal physical signatures, we view Volantyx’s approach as a necessary evolution in counter-UAS architecture. The company’s explicit acknowledgment that it lacks fielded deployments or contract awards underscores the significant gap between conceptual architecture and operational validation. The early 2027 target for effector manufacturing will be a critical milestone to monitor as the company attempts to transition from a development-stage startup to an active aerospace supplier.

Lockheed Martin Offers Peru $1.8B F-16 Block 70 Offset Package
Lockheed Martin proposes a $1.8B industrial package for Peru’s F-16 Block 70 program, including UAS assembly and MRO expansion.
Lockheed Martin has outlined a $1.8 billion industrial and social collaboration package for Peru, designed to integrate local firms into the global aerospace supply chain as part of the country’s F-16 Block 70 procurement program.
Announced in a press release on August 26, 2026, the offset proposal follows the Peruvian government’s April 2026 decision to acquire an initial batch of 12 F-16 Block 70 aircraft. The comprehensive package aims to position Peru as a regional hub for advanced unmanned systems and aerospace services.
Expanding Peru’s aerospace industrial base
The proposed industrial agreement focuses heavily on technology transfer and domestic manufacturing. Key components include the domestic assembly of an Unmanned Aircraft System (UAS) tailored for the Latin American market, the establishment of joint research hubs, and the creation of a UAS Technical Institute. The package also outlines plans to expand Peru’s high-tech maintenance, repair, and overhaul (MRO) footprint.
“As we collaborate with the local industry, we aim to deliver tangible, high-value opportunities that build a skilled workforce, enable knowledge transfer and create lasting economic impact on both sides of the partnership,” said Tara Lause, Vice President of Business Development for the Integrated Fighter Group at Lockheed Martin.
Lause added that the procurement creates enduring alliances and industrial collaboration opportunities with the United States and other partner nations.
Fleet modernization and electronic warfare capabilities
Peru is currently working to replace its aging fleet of Soviet-era MiG-29s and French Mirage 2000s. The F-16 Block 70 was selected over competing bids from Saab and Dassault. To equip the new fleet, the government of Peru selected L3Harris Technologies to provide its AN/ALQ-254(V)1 Viper Shield all-digital electronic warfare suite, a decision announced on August 17, 2026. The Viper Shield system provides advanced radar warning and jamming capabilities.
Lockheed Martin noted that the F-16 is currently operated by 29 countries, with a global fleet of 2,800 aircraft. Mike Shoemaker, Vice President of the Integrated Fighter Group at Lockheed Martin, stated that the selection highlights the aircraft’s operational performance and ability to meet pressing defense requirements.
AirPro News analysis
The announcement of a $1.8 billion industrial offset package is a strategic move by Lockheed Martin to solidify the F-16 Block 70 sale amid a complex political environment in Lima. While the Peruvian government selected the aircraft in April 2026, regional defense reporting indicates that the procurement process has encountered delays linked to ministerial resignations and defense budget debates. By offering substantial domestic manufacturing opportunities, including UAS assembly and MRO expansion, Lockheed Martin is providing Peruvian leadership with a strong economic justification to finalize the state-to-state contract. We view this comprehensive technology transfer as a critical lever in moving the procurement from selection to a finalized, funded agreement.
