Defence

Contribution

There was no question in that intervention, but I am glad that the hon. Lady agrees that the Government need to get on and deliver the defence investment plan. To be fair, MPs from across the House have said so, including the Chair of the Defence Committee. We all know that it is in the national interest for the DIP to be published. After all, the defence investment plan being delayed has consequences, the most serious of which are for our military personnel, who we want to have the best equipment for their job. In taking the decision to pause urgent procurement and instead boil the ocean, the Defence Secretary walked into a Treasury trap. Procurement has been on hold ever since, and the Ministry of Defence has been forced to focus on in-year savings, including £2.6 billion for this year alone. Such penny-pinching explains why, until HMS Dragon finally arrived on the scene, we had no warships in the middle east for the first time in decades. One of the most critical consequences of the delay to DIP is the Sea Viper Evolution procurement. The fact that a US destroyer intercepted at least one of the missiles that Iran fired at our sovereign territory on Diego Garcia underlines how important it is that our Type 45s are able defend against the most advanced threats. For the UK, that requires the Sea Viper Evolution upgrade for our Type 45 destroyers. In my own SDR submission as shadow Defence Secretary, through numerous speeches in the House and in many written questions, I have repeatedly urged the Government to accelerate Sea Viper Evolution as a priority for our munitions plan. I am sure that members of the public who are watching this debate, worried about Iran’s attack on Diego Garcia, would expect such a capability to have been ordered as rapidly as possible. However, in a written answer this January, when I was once again chasing this critical upgrade, I received the inevitable response that continued progress on Sea Viper Evolution remains “subject to the defence investment plan.” That is the problem in a nutshell—the impact of Labour’s procurement freeze in real time. The reality is that Sea Viper Evolution is not due to reach full operating capability until late 2032.
