European Union leaders meeting in Copenhagen this week will discuss a slate of flagship defense projects, including a European drone wall and an air-defense shield.

The plans have gained urgency following a wave of incursions into NATO airspace by Russian aircraft. The European Commission, the bloc’s executive arm, laid out its proposals in a paper published Monday as part of a strategy to get the bloc to close gaps in the continent’s defense by 2030.

The focus is on areas identified as ones requiring the most urgent action, including air and missile defense, and drones. The paper will serve as the basis for discussion when leaders meet in the Danish capital later this week.
