One small manufacturer based in England said: “We are ready to go; we have built factories that could start making equipment tomorrow. But we can’t until an order is placed.”

Armored vehicle maker Supacat has said that while its business is stable, suppliers will suffer without a predictable path ahead.

“This is about the wider industry and our partners in the supply chain that have been contributing,” Toby Cox, the company’s head of sales, told POLITICO. “Our assumption is we don’t get more [orders], some of these companies will have a downturn in their orders.”

Keeping production lines warm

Andrew Kinniburgh, defense director general of manufacturers association Make UK, echoed those concerns.

While the industry “warmly welcomed” the Defence Ministry’s commitment to boost SME spending, he said, “the MOD must give companies certainty of long-term demand signals and purchase orders, allowing businesses to make the private investments needed in people, capital, and infrastructure.”

Mike Armstrong, U.K. managing director of German defense firm Stark, which has recently opened a plant in Britain, added: “Giving the industry a clear view of future requirements is the fastest way to ensure the U.K. and its allies stay ahead.”
