Karlskrona: The Naval City at the Heart of Sweden's Green Transition and Innovation

Karlskrona, a city built on islands, is not only a UNESCO World Heritage Site, sharing its prestigious status with iconic landmarks such as the Colosseum and the Taj Mahal, but also a pivotal hub for Sweden's marine industry and green innovation. Founded under the reign of King Charles XI in 1680, the city was designed by the finest architects of the Baroque period, with an enduring legacy in shipbuilding that has shaped its identity. Historically significant, Karlskrona was home to Sweden's largest workplace, the Naval Shipyard, in the 18th century. Today, it stands at the forefront of modern naval technology, with Saab Kockums, a leading enterprise in submarine manufacturing, working on some of the world's most advanced vessels. Recent orders, such as the three new submarines for Poland, highlight the global importance of Karlskrona in maritime defense. Further propelling its status, Karlskrona is central to Sweden's marine infrastructure, particularly with projects spearheaded by NKT, which is currently expanding the world's largest submarine cable factory in Verkö. This expansion is not just about creating infrastructure; it is also an EU-priority NetZero project focused on aiding Europe's transition to sustainable energy and enhancing international business ties. Jonna Lindbergh, head of growth and business in Karlskrona, emphasizes the city's unique location, stating, "We really live right in the middle of it—the city is built in the sea, and that is exactly why we have Sweden's naval base here and why we build submarines and surface vessels here." The city's economic growth has not gone unnoticed; the Swedish Agency for Economic and Regional Growth recognizes Karlskrona as one of the three growth engines in southeastern Sweden. Major companies like Saab and NKT not only provide numerous jobs but also stimulate innovation, creating an ecosystem of specialized suppliers that strengthens the region's economic fabric. Tobias Larsson, professor of mechanical engineering at Blekinge Institute of Technology, asserts, "It is difficult to find an equally exciting innovation environment within marine technology anywhere else." Analysis of the region's future reveals the depth of its aspirations. With massive investments, including NKT's eleven billion Swedish krona commitment to the Verkö factory—set for completion in 2027—new job opportunities will emerge. Jonna Lindbergh notes that Verkö has the highest investments per square meter in Sweden, drawing even more businesses to the area, creating what she calls a "positive spiral" of economic growth. The demand for skilled workers is surging, leading local institutions to enhance their educational offerings. The Blekinge Institute of Technology (BTH) features Sweden's only master's degree in marine technology, focusing on both electrical and mechanical engineering. The program has gained popularity, with a commendable 25% enrollment of women, breaking typical gender norms tied to technical fields. Moreover, the institute fosters collaboration between students and companies, as students engage with local businesses from the very start of their studies, paving avenues for future employment. This hands-on approach breeds applied research and development, especially in critical areas like blue energy, green transition, and marine technology through the Marine Technology Center, which connects public sectors, businesses, and researchers, catalyzing innovation. Beyond economic growth, the lifestyle in Karlskrona is attractive, with plans for approximately 3000 new homes fostering comfortable and diverse living. Residents enjoy the merging of city life with the natural beauty of archipelago forests, fields, and the sea, with many, including Jonna Lindbergh, finding their commute to work a mere seven minutes by bike. Such accessibility promotes a strong community spirit, reinforced by local initiatives aimed at enhancing safety and quality of life. Karlskrona’s unique blend of maritime history, innovation, and educational opportunities positions it as a city of the future. The renewed focus on total defense and environmental sustainability further solidifies its relevance. As Tobias Larsson points out, technology developed in Karlskrona strengthens national defense capability, encompassing both military submarines and civilian solutions, such as protections for underwater electric cables and cybersecurity software. With a population of 66,400 and more than 6000 companies, Karlskrona is a vibrant business hub where entrepreneurial spirit thrives, demonstrating how innovative solutions can emerge from historical roots to meet modern challenges. As it progresses, Karlskrona is not only shaping its own future but also contributing to the broader narrative of sustainable development and technological advancement in Sweden.
