France and Poland will build a telecommunications satellite for the Polish military, according to the companies involved in the project. The value of the deal was not disclosed during a meeting between French President Emmanuel Macron and Polish Prime Minister Donald Tusk in Gdansk. The initiative is part of the European Commission's Readiness Defence Plan, which aims to get the continent ready to defend itself by 2030. France and Poland, which have the highest defence spending as a percentage of GDP among NATO members, signed a cooperation treaty last year that includes a mutual assistance clause and a pledge to deepen military and technological links between the two countries.
