Revenue increased nearly 7 percent to $27.1 billion, and Raytheon employed about 67,000 people at the end of 2018, up about 3,000. Raytheon announced plans in June 2019 to merge with fellow CT 100 defense contractor and aerospace firm United Technologies. The companies expect the all-stock merger, which would create Raytheon Technologies, to close in the first half of 2020, pending shareholder and governmental approval. In the meantime, Raytheon is progressing toward a goal to deploy next-generation virtual collaboration tools in 100 percent of its locations by 2020, a goal set in part to reduce the environmental impact of its business travel.
