Brexit jitters are causing some firms to re-evaluate their British investments, but U.S. aerospace and defense sector giants Boeing and Raytheon say they're staying put.
Speaking to CNBC at the U.K.'s Farnborough Airshow, John Harris, CEO of Raytheon International, said the outcome of the U.K.'s referendum on European Union (EU) membership wasn't prompting a scare.
"We've been here in the U.K. for the better part of 100 years. We've got a strong company here, thousands of employees, fantastic capability and we intend to remain here," Harris said.
Harris called Brexit a "long play," saying it would be years before the details of the U.K.'s exit from the EU were known. Meanwhile, "we're very, very enthused about the opportunities and see no meaningful change in the short term," he said.
"While these changes are of import and concern, our job is to really understand the marketplace, make adjustments as needed, and remain a trusted partner," Harris added.
