Lockheed Martin stock slipped 2.7% today even though they announced some positive news. They partnered with Saildrone during a naval exercise to successfully test fire missiles from a remote drone boat. They plan to expand this collaboration by putting larger missile launchers and sonar systems on bigger drone vessels. This gives Lockheed a backdoor into Navy drone sales without having to build the boats themselves. It's a bit strange the stock dropped on news of an expanding market.
