Subsidiary of Summa Defence Oyj, Lännen Tractors Oy and Lainisalo Defence Painting Oy, have signed an agreement under which Lännen Tractors’ surface treatment operations in Loimaa will be transferred to Lainisalo Defence Painting Oy. As part of the arrangement, Lainisalo Defence Painting Oy will acquire the paint shop including its equipment, and a total of five employees from the Loimaa surface treatment operations will transfer to the company as existing employees.

The outsourcing supports Lännen Tractors Oy’s strategic focus on the manufacturing and assembly of multi-purpose machines and enables controlled growth of production volumes. At the same time, surface treatment is transferred to a partner with long and well-established experience in demanding defence and government customers, strict quality requirements, and high delivery reliability.

Through the arrangement, Lännen Tractors Oy gains access not only to the Loimaa unit but also to the entire six-site network of the Lainisalo Group, two of which are located in Estonia. The network provides significant capacity and delivery flexibility and improves the predictability and quality of surface treatment across the supply chain.

The arrangement also supports the growth strategy of the Summa Defence Oyj Group and strengthens Lännen Tractors Oy’s ability to respond to growing demand in the defence sector quickly, reliably, and in accordance with high quality standards.

“The arrangement supports our focus on our core business and improves our delivery capability as volumes grow. Lainisalo Defence Painting Oy’s strong and long-standing experience with demanding defence customers, certified processes, and delivery reliability is a clear strategic advantage for us,” says Veli Ollila, CEO of Lännen Tractors Oy.

Uudenkaupungin Työvene Oy, Summa Defence Plc group company has signed a contract with the German Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw) for the design and construction of a SWATH-based Personnel Transfer Vessel (PTV) intended to support German Navy operations in the Baltic Sea.

The vessel will be based in Neustadt in Holstein, where it will play a key role in transferring personnel from the naval harbor to larger naval vessels operating offshore. Designed to accommodate up to 60 personnel, the vessel will enable safe and efficient personnel transport and ship-to-ship transfer operations at sea.

The new vessel will utilize Small Waterplane Area Twin Hull (SWATH) technology, which offers exceptional stability and seakeeping performance compared to conventional hull forms. This provides a highly stable platform for personnel transfer operations, improving safety and operational efficiency even in challenging sea conditions typical of the Baltic Sea.

A specialized access and transfer system will allow personnel and crew members to safely embark and disembark between the transfer vessel and larger naval ships while underway or at sea.

“This project highlights our ability to deliver highly specialized vessels tailored to demanding operational requirements,” said Nils P. Olschner, Director Sales & Business Development at Työvene. “The SWATH platform provides an extremely stable working environment, making it ideally suited for personnel transfer missions. We are proud to support the operational capabilities of the German Navy.”

The vessel will be built at Työvene’s shipyard in Uusikaupunki, Finland, and is scheduled for delivery following completion of construction, testing, and sea trials still in 2026.

With this project, Työvene further strengthens its position as a supplier of high-performance aluminum workboats and specialized mission vessels for governmental and naval customers.

Lännen Tractors Oy, a subsidiary of Summa Defence Plc, has received the largest single order in the company’s modern history for its NATO‑compatible Lännen 8800M‑DF multipurpose machines. The order, valued at EUR 35 million, has been placed by a European NATO country and the deliveries will take place during 2026, 2027, and 2028. 

“This is the largest single order in Lännen Tractors’ modern history. It strengthens both the competitiveness of our products and our position within the European defence industry. We are extremely proud to deliver these machines for demanding NATO use.” – Veli Ollila, CEO, Lännen Tractors Oy 

Comprehensive delivery scope 

The delivery includes not only the multipurpose machines but also extensive spare parts packages and a commitment to provide commissioning and maintenance training for the customer’s personnel. 

Scaling up production – strengthening capacity 

Lännen Tractors began preparing for a significant increase in production volumes as early as November 2025 with measures that were already underway. Located in Loimaa, Southwest Finland, the nearly two-hectare factory, equipped with modern machinery, offers an excellent framework for increasing capacity. Production processes have been developed in recent months as a separate project to meet the needs of growing demand in the defense industry.

Lännen 8800M‑DF receives NATO‑compatible product code 

The Lännen 8800M‑DF multipurpose machine has been assigned a NATO Stock Number (NSN 2420-58-002-2440), expanding its accessibility within NATO procurement systems. With the support of Summa Defence, the company has activated its presence in European markets where no equivalent machine with similar performance exists. 

Key machine capabilities: 

– excellent off‑road mobility 

– high transfer speed 

– full remote control of all machine functions 

– wide and rapidly interchangeable attachment portfolio 

These features make the machine particularly effective for combat engineer operations, such as obstacle clearance, construction, obstacle emplacement, and field infrastructure maintenance. 

Dual-use products form the foundation of Summa Defence’s strategy 

Summa Defence was founded in 2025 and began its public trading on the Nasdaq First North Growth market in June 2025. The core ideology behind Summa Defence’s founding is to bring together entrepreneur-driven small and medium-sized enterprises with growth potential in comprehensive security and defense technology solutions, particularly dual-use products. In line with Summa Defence’s strategy, the Lännen 8800M-DF represents such dual-use products, which have a strong foothold in the maintenance of society’s critical infrastructure and have also been further developed for defense use. 

“This significant order received by Lännen Tractors is based on Summa Defence’s ‘Together We Are Stronger’ philosophy. As a publicly traded company, Summa Defence provides its subsidiaries with the credibility and resources to compete for even larger public projects. Lännen’s excellent and proven dual-use technologies gain new momentum in the market through such significant deals,” says Timo Huttunen, CEO of Summa Defence.

Summa Defence’s subsidiary Uudenkaupungin Työvene Oy is building vessels at two shipyards located in Uusikaupunki and Olkiluoto, Finland. The Uusikaupunki shipyard is currently engaged in the construction of two offshore patrol vessels, being built in cooperation with the Meyer Turku shipyard. The hull of the most recent vessel arrived at the Uusikaupunki yard at the turn of the year, and work on the offshore patrol vessels is progressing well before the winter holidays.

In addition, two service vessels for offshore wind farms are being built in Uusikaupunki, with the commissioning of one of them currently underway.

Uudenkaupungin Työvene bought the Olkiluoto shipyard in June 2025, immediately following Summa Defence’s listing. In Olkiluoto, two battery-hybrid passenger vessels are being built for Sweden’s west coast, operating out of Strömstad.

The combined workforce of the shipyards is approximately 500 employees, including Uudenkaupungin Työvene’s own personnel and subcontractors. Demand in the professional and specialized vessel market remains strong, providing good conditions for the long-term development of operations.

Nearly 20 Watermaster eco-dredgers have been delivered to India in recent years. The latest machine has begun the work on the Yamuna River in New Delhi, a city of over 25 million people.

The Yamuna is one of India’s most important rivers, but it faces heavy pressure from untreated wastewater, sludge and solid waste. The Najafgarh drain has been described as carrying nearly 70% of the pollution load entering the Yamuna. 

Dredging operations have now officially started in the Najafgarh drain. The amphibious multipurpose Watermaster eco-dredger is removing silt and sludge and clearing aquatic weeds and waste. 

The goal is to reduce the load reaching the Yamuna and support flood management ahead of the monsoon season. 

The new local government of New Delhi has identified Watermaster technology as a key tool to improve water security in the region. New Delhi’s Deputy Chief Minister Parvesh Sahib Singh visited Finland in late 2025 and now inaugurated the new Watermaster on the Yamuna River a couple of weeks ago.
