Terma and Kongsberg launch defence aviation venture

Danish defence technology company Terma and Kongsberg Aviation Maintenance Services have formally launched Defence Aviation Services, a joint venture developing military aircraft maintenance, repair and overhaul capacity in Denmark to support the sustainment requirements of Nordic and allied air forces.

The launch took place on 21 October 2026 at the Norwegian Ambassador’s residence in Copenhagen, attended by representatives of the Danish and Norwegian defence communities and industry. The companies intend to combine existing technical experience with the development of additional personnel, engineering capability and industrial facilities in Denmark.

Defence Aviation Services will provide maintenance, repair and overhaul services for military airborne platforms. Its stated objectives include improving security of supply, strengthening regional maintenance capacity and establishing a workforce capable of supporting aircraft throughout extended service lives.

The venture brings together complementary capabilities. Terma has an established role supporting the Danish Armed Forces, while Kongsberg Aviation Maintenance Services has decades of experience maintaining military aircraft and related equipment in Norway, including work involving the F-35, P-8 and F-16, helicopters and aircraft engines.

That experience belongs to the participating companies and does not establish that Defence Aviation Services has already received contracts for each aircraft type. The October launch did not identify the new business’s first customer, specific fleet assignments or maintenance workload.

The partnership developed from an August 2024 teaming agreement between Terma and Kongsberg Aviation Maintenance Services, under which the companies agreed to pursue cooperation on Danish military aviation maintenance. The venture was subsequently established, with its formal public launch taking place in October 2026.

A separate August 2026 agreement between Airbus Helicopters and Terma also referred to the newly formed Terma–Kongsberg venture as a potential foundation for regional maintenance capabilities. That agreement identified areas for possible cooperation rather than announcing a completed maintenance contract for Defence Aviation Services.

Military aircraft sustainment involves far more than repairing equipment after a fault. Aircraft require scheduled inspections, replacement of components approaching defined service limits, rectification of defects and the management of technical information throughout their operating lives.

Different tasks require different facilities and levels of technical authorisation. Some routine work can be performed close to operating units, while deeper structural repairs, engine maintenance or specialised electronics testing may require dedicated workshops, tools and personnel with relevant qualifications.

The distribution of these activities affects aircraft availability. Moving an aircraft or major component to a distant maintenance facility can add transport and scheduling requirements, particularly when work depends on specialist equipment or parts that are not available locally.

Developing more maintenance capacity within Denmark could reduce certain dependencies on external support locations, provided the new organisation secures appropriate work packages and technical access. The actual reduction in turnaround times will depend on the equipment supported, its maintenance requirements and the capacity established.

Aircraft maintenance also depends on configuration control. Two aircraft of the same basic type may have different equipment standards, software versions or modification histories, changing the procedures and parts applicable to each. Maintenance personnel must work against approved documentation for the specific aircraft and task.

Component traceability is another requirement. Records must establish the identity, condition and service history of relevant parts so that equipment can be assessed before installation or return to operation. Incorrect configuration information can create problems even where a replacement component appears physically compatible.

Modern aircraft increasingly rely on electronic and software-controlled systems. Fault investigation may involve examining diagnostic records, testing sensors and controllers, and establishing whether a problem arises from the equipment, associated wiring or interactions between systems.

These activities require access to appropriate technical data and test equipment. Depending on the platform, that access may be subject to contractual, regulatory or security restrictions, limiting which organisations can perform particular maintenance tasks.

Establishing an industrial maintenance service therefore requires more than constructing workshop space. The new business must develop processes governing work authorisation, inspection, engineering decisions and the release of equipment after maintenance, alongside suitable arrangements for tools, spare parts and technical documentation.

Personnel qualifications are equally important. Aircraft technicians and engineers develop specialised competence through training and supervised experience, and the tasks they may perform depend on the requirements of the equipment and maintenance organisation involved.

A facility supporting several aircraft types must maintain those competencies across different technical systems. Knowledge of one aircraft’s propulsion, avionics or structural design cannot automatically be transferred to another type without the relevant procedures and authorisations.

The Nordic dimension creates opportunities for cooperation where national air forces operate common aircraft families. Shared requirements may support the development of specialist workshops, component repair arrangements and training resources that would be difficult to sustain individually at a smaller scale.

Even where aircraft types are common, the participating forces may have different equipment configurations, contractual obligations and support arrangements. The availability of the same basic platform across several countries therefore does not remove the need for customer-specific agreements and qualification.

Defence Aviation Services intends to develop capacity around these shared industrial requirements. Kongsberg’s existing maintenance experience provides a technical foundation, while Terma contributes knowledge of Danish defence requirements and the country’s established industrial environment.

The companies have not disclosed the venture’s initial capital investment, ownership proportions, planned headcount, workshop capacity or start date for routine customer maintenance. Without those details, it is not possible to quantify the additional aircraft throughput expected from the business.

Oscar Cosman Brøndum, interim chief executive of Defence Aviation Services, has indicated that building external maintenance capacity could allow military personnel to concentrate on operational duties. That outcome will depend on the work transferred to the venture and the division of responsibilities agreed with its customers.

The partners also intend to develop specialist personnel and long-term industrial competence within Denmark. Sustaining those capabilities will require an appropriate flow of maintenance work, because training investments and specialist facilities must be supported by continuing demand as well as the initial resources used to establish them.

With the venture formally launched, attention will move to the establishment of its operating capabilities, agreements with customers and the qualification of facilities and personnel for particular aircraft maintenance tasks. Those milestones will determine when the Danish-Norwegian partnership begins adding measurable capacity to military aviation sustainment.
