BERLIN — The British military of the future is going to have a strong German accent.

Defense ministers from the United Kingdom and Germany will sign a sweeping bilateral defense pact between Europe’s two biggest military spenders on Wednesday. It covers everything from joint missile development to extra exercises in the Baltics, hosting rights for submarine-hunting planes in Scotland along with a major artillery factory deal for Düsseldorf-based weapons-maker Rheinmetall.

The Trinity House text will complete a triangle of defense deals among Europe’s big three military nations. The others are the pre-Brexit 2010 Lancaster House agreement between the U.K. and France and the 2019 Aachen Treaty binding France and Germany on military coordination.
