Defence manufacturer Raytheon UK has signed a £250 million contract with the Ministry of Defence to support the Royal Air Force's Shadow aircraft fleet.
Under the deal, the company will provide maintenance, airworthiness management and design organisation to the aircraft, with work beginning in April 2019.
Raytheon UK will also support aircraft modification design and integration under the contract, with an opportunity to upgrade the aircraft to the Mk2 version.
Two hundred full-time jobs will be secured at Raytheon's North Wales hub as a result of the contact.
Defence Minister Stuart Andrew said:
"This £250 million investment will ensure the UK retains its position as a global leader in battlefield intelligence gathering for UK troops and our NATO allies."
Richard Daniel, chief executive and managing director of the manufacturer, said: "Our work in advanced defence and security systems, cyber protection and skilled training ensures our armed forces have the technology they need to keep the UK safe and secure."
