BERLIN, June 7 (Reuters) - Germany is looking into buying eight additional F-35 fighter jets made by U.S. defence giant Lockheed Martin, a military source told Reuters on Friday, on top of the 35 jets it has already ordered.

Berlin is currently checking the costs of such a purchase, the source said, with the stealthy aircraft seen as the most advanced fighter jet on the market.

In 2022, Germany decided to order 35 F-35 including missiles and other weapons for some 10 billion euros.
