It is the latest in a series of important international contracts for the Lisburn company, which is already well known in the field of UAVs for services in Afghanistan.

Responding to the deal NP Aerospace’s chief executive John McDonough said: “This is a significant contract win, which follows two major export awards to export countries such as Saudi Arabia, Kuwait and Croatia.

“Sales to these export markets are extremely valuable to NP Aerospace, as are our subcontract opportunities. CNAC (UK Standards and Certification Convention) is an international qualification and we will be able to immediately apply our proven technologies to our UK military clients.”

The contract will help NP Aerospace, which is 100% owned by its parent company QinetiQ, expand its equipment and flight testing services. It will also provide work for both QinetiQ and its five suppliers in the UK.

Within a month of taking control of the Rosyth-based engineering company, QinetiQ last year bought out its two main suppliers in the UK, Gilintsi and Davies & Evans, and now supplies more than 95 per cent of NP Aerospace’s work.

When taken with NP Aerospace’s experience in Iraq and Afghanistan, McDonough says the two companies now “represent a very important part of our security portfolio”.

He added: “This contract further validates NP Aerospace’s effectiveness in a range of missions, from first into Syria to battlefield reconnaissance.”
