This research service provides an overview of the European military helicopter market. Helicopter fleets are an essential asset for European militaries. However, maintaining them at a state-of-the-art level to ensure mission readiness requires constant investments and upgrades, often entailing the incorporation of new technologies into legacy platforms. Many European countries are conducting helicopter modernization programs. Additionally, the North Atlantic Treaty Organization (NATO) and the European Union (EU) are providing frameworks that enable members to invest in joint helicopter development projects and continent-wide training initiatives. The search for lightweight, quieter, and more sustainable military rotorcraft is boosting innovation in Europe. Nevertheless, challenges such as the energy shortage and the consequent soaring prices that affect defense manufacturers can halt growth. This study outlines the most relevant joint and individual projects and key contracts in the region. Profiles of the leading companies in the industry have also been provided. The study also analyzes the factors driving and restraining growth in the market and identifies the growth opportunities emerging from the changes in this space for market players and stakeholders to leverage.
