I agree with the right hon. Gentleman, who has raised that point repeatedly in recent months. We have to decide what reserves we need, but that is no replacement for the development of our future capabilities.
First, on our economy, our defence aerospace sector makes an enormous contribution. It is the core of our wider defence industry, which directly employs more than 142,000 people, with a further 116,000 indirectly employed in the supply chain. In 2016, BAE Systems alone contributed £11.1 billion of gross value added to the UK—equivalent to 0.6% of our entire economic output—but there is further additional value to ensuring that those defence jobs stay in the UK. The Royal United Services Institute has calculated that for every pound the Government spend on a defence contract when the good or service is generated in the UK, the Treasury receives 37p back in revenue, as well as the new platform or system we have procured.
It is self-evident that a strong defence industry is a major contributor to a strong national economy, and our defence aerospace industry supports thousands of well-paid and highly skilled jobs, the majority of which are outside the south-east, as well as boosting our economy
through exports of world-class products. Our defence aerospace sector accounts for 88% of all defence exports —an incredibly important aspect of our economy, especially as we look to leave the EU, not least for the impact on our future balance of payments.
But there are challenges in the sector that fundamentally relate to two factors. One is that export sales typically depend on the use of future platforms by our own RAF—the British brand and RAF stamp of approval mean a huge amount for other state actors. When buying British is key for the global success of the sector, we need to pay attention.
The second significant challenge is the extended lead-in times and development processes that characterise the defence aerospace industry. That requires a long-term strategy, not a short-term fix, to ensure a steady drumbeat of orders and constant research and development to maintain confidence within the industry and to protect jobs and our domestic skills base.
We have seen recently what happens when that certainty is missing from the market, with BAE announcing up to 2,000 redundancies owing to a gap in its order book. Those job losses are not just a blow for those workers and their families, but could result in a loss of skill and expertise that could set us back a generation. I believe that those jobs could be protected in the short term if the Government committed to bringing forward the order for the new Hawk aircraft for the Red Arrows and to securing the next wave of export contracts for that aircraft.
