The firm, which is supplying the UK's controversial new F-35 fighter aircraft and turrets for the military's new Ajax fighting vehicles, hopes to use the UK as a base to export kit to Gulf States like Qatar.
Asked if Brexit would boost the country's figurative stock, Hewson said: "I'm sure potentially it could. It depends on the government and the policies it puts in place. "We find it already an attractive place to invest. One of the things we are working on is exporting from the UK to other countries. We've just expanded our Ampthill facility and added 40 jobs. We've already spent about £23 million in that facility over the past 10 years to make it a centre of excellence for turret manufacture," she added.
The F-35 deal figures highly in Lockheed's' calculations. The US company stands to make more than £300 billion from the deal, which is the most expensive program of its kind ever undertaken. The fighter's destiny is tied to that of the UK's forthcoming Queen Elizabeth Class aircraft carriers, which, while wracked with delays, are due to enter service by 2020.
Hewson was speaking at the Farnborough air show, the UK's annual arms trade centrepiece. She took the opportunity to talk down concerns over the F-35, telling an audience: "We're very happy with the progress of the programme. There are no technical show-stoppers at all."
Since the Brexit vote the pound has diminished by 30 percent against the Japanese yen, leading new Chancellor Philip Hammond to suggest an influx of business could also be expected from Asia. "Just three weeks after the referendum decision, it shows that Britain has lost none of its allure to international investors," he said.
Comment: War is big business. The bigger the conflict, the more money is in the pockets of those who serve war. It is a catastrophe loop: the more people killed and cities destroyed, the more valuable become the goods that facilitate, and the more money is in the pockets of those who perpetuate. Just business, the biggest and most lucrative one on the planet.
