I thank my noble friend for those points. The last time this issue was raised in a debate, he asked the Minister to consider red teaming the Dreadnought programme. The US regularly red teams its resilient military systems and is candid about its vulnerability to this threat. We are investing a significant amount of money—and, most importantly, the security of the next 50 years—in a programme that has vulnerabilities. It needs to be red teamed and we need to admit that protecting that system from this threat will cost significantly more than the Government are currently investing in cybersecurity for the whole country for the next five years.
