The main factor behind the move is the pace of production of the Typhoon aircraft, Sky News have reported, citing sources close to BAE.
Brexit is not believed to be a factor in the move, Sky said, citing sources close to the company.
We have reached out to BAE who have yet to respond.
The defence giant is expected to make an announcement later today. The cuts are thought to relate to its two plants in Lancashire.
10,000 people work at the Warton and Samlesbury plants where aircraft assembly takes place.
Separately, the company is today announcing proposed reductions to its Military Air and Information and Maritime Services workforce to align capacity more closely with current and expected orders.
Charles Woodburn, Chief Executive, BAE Systems plc, said:
“BAE Systems is a world leader in technology, advanced manufacturing and engineering and our diverse portfolio provides a strong platform for future growth. The organisational changes we are announcing today accelerate our evolution to a more streamlined, de-layered organisation, with a sharper competitive edge and a renewed focus on technology. These actions will further strengthen our company as we deliver our strategy in a changing environment.
Separately, we are also announcing actions at some of our UK sites to align our workforce capacity more closely with near-term demand and enhance our competitive position to secure new business. Those actions are necessary and the right thing to do for our company, but unfortunately include proposed redundancies at a number of operations. I recognise this will be difficult news for some of our employees and we are committed to do everything we can to support those affected.”
BAE Systems is involved in several major defence projects, including the Lockheed Martin F-35 Lightning II, the Eurofighter Typhoon, the Astute-class submarine and the Queen Elizabeth-class aircraft carriers. BAE Systems is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index.
The company is among the world’s largest defence entities; it was ranked as the third-largest in 2016. Its largest operations are in the United Kingdom and United States, where its BAE Systems Inc. subsidiary is one of the six largest suppliers to the US Department of Defense.
Other major markets include Australia, India and Saudi Arabia. The company was formed on 30 November 1999 by the £7.7 billion merger of two British companies: Marconi Electronic Systems – the defence electronics and naval shipbuilding subsidiary of the General Electric Company plc and British Aerospace (BAe) – an aircraft, munitions and naval systems manufacturer.
