Strategic Defence Review

Lord Stirrup Excerpts

Wednesday 9th October 2024 Grand Committee

[Lord Stirrup (CB)]

My Lords, I, too, am grateful for the opportunity to debate the strategic defence review that the noble Lord, Lord Robertson of Port Ellen, is leading for the Government. I will start by raising a point that is formally outwith his remit but is fundamental to the issues that he is addressing—the defence budget. NATO has calculated that for its members to contribute military capabilities adequate to the challenges that the alliance now faces, they will need to spend around 3.7% of GDP on defence. Even if NATO has overdone things a bit—it is not at all clear that it has—it is certainly the case that investment in defence needs to be above 3% of GDP, not the 2.5% that the Government say that they aspire to but for which they have not so far set out a firm plan. It is worth saying that 3% of GDP for the UK, allowing for all the accounting changes that have taken place in recent years, would not be much more than we were spending in 2010, when Europe was not facing a severe threat from Russia. It is important to make this point today because, if the issue is not addressed, the current defence review would be like someone deciding whether to buy two or three fire extinguishers while the building is burning around their ears.

This dichotomy is thrown into stark relief when one looks at the substantive issues that the review will need to address. A good starting point is the recent report from your Lordships’ International Relations and Defence Committee on the implications of the Ukraine war for UK defence, to which the noble Lord, Lord Alderdice, has referred. It is a good analysis and my only real criticism is that the compelling chapter on the importance of building mass focuses almost exclusively on the British Army, whereas the shortcomings in this area are being felt across all three armed services. On current plans, for example, the UK will have only three combat air squadrons by 2040—that would not even have filled one main operating base in my day. Given the lessons from Ukraine about the importance of air power, can anyone really think that this is acceptable? Numbers of airborne early warning and control aircraft are also woefully inadequate. In the case of the Royal Navy, the operational availability of nuclear attack submarines verges on the derisory. Even before our donations to Ukraine, stocks of weapons came nowhere near what even the most optimistic observer could regard as satisfactory. I could cite many other examples.

If we wish NATO to exercise a powerful deterrent effect on Russia, these issues must be addressed. The platforms in all three environments need the trained people, the weapons stocks, the logistics support and the defence industrial base to sustain them through the draining effects of protracted combat. Then there is the vulnerability of the home base. The necessity for significantly improved deterrent capability within NATO reaffirms the importance of the north Atlantic link, but that will be of little avail if the UK end of that link is not secure. At the moment, we could not counter the kind of missile attacks that Iran has launched against Israel. The requirement for a robust integrated air defence system can be ignored no longer. Effective defence requires an integrated system, which cannot be had on the cheap. It requires sensors, information management technology, surface-to-air weapons and air-to-air platforms and weapons.

Control of UK airspace will not of itself be sufficient, though. Again, the experience of Ukraine shows that trying to fight a land campaign without air superiority is a recipe for, at best, a long and bloody struggle and, at worst, defeat. There is nothing new in this. Neither El Alamein in 1942 nor Normandy in 1944 would have been successes without air superiority. The precise means of achieving that superiority will of course change over time, as technology offers new ways of doing old things, but the suppression and destruction of enemy air defences will continue to be a keystone of that effort. This is a complex and challenging role that involves cutting-edge and constantly evolving systems and technologies. It will also require the ability to operate effectively in the face of a hostile electronic and cyber environment, which of course will be true of the Armed Forces and their capabilities more widely.

The electronic warfare challenge that has emerged in Ukraine is well beyond anything we have ever seen before and we must expect that kind of challenge, or even greater, to be a feature of future battle spaces. This will require a response that goes beyond the purchase of certain kinds of equipment. It will need the fusion of experts and technology in an organisation with the agility, and the requisite industrial capacity, to respond to constantly evolving threats and the ability to adapt front-line platforms and tactics accordingly. Such agility and adaptability will be needed more widely across the entirety of our defence capabilities.

I could cite many other examples of the kind of improvements that will be required to defence in the years ahead, improvements across all three environments, and I have not even touched on the crucial issues of people—their recruitment, training and retention—that will be fundamental to our capabilities, let alone the question of wider national resilience. Time does not permit me this afternoon to do much more than to scratch the surface. Suffice to say that we face a double challenge: we have to make good the shrinking and hollowing out of our Armed Forces that has been the handiwork of successive, delinquent Governments. At the same time, we have to adapt those forces to meet the stark and pressing challenges of the future.

There will of course be debates about precisely how those future capabilities are to be provided, but two things seem beyond doubt. The first is that those capabilities will be essential. The second is that they are well beyond the financial guidelines under which this review is operating, so I end where I began: with the Budget. The mantra seems to be that no more money is available for defence. Of course the money is available; it is a question of choices and priorities. If the Government say that they cannot afford more than 2.5% when the need is so apparent, what they are really saying is that the safety and security of this country and its people are not their top priority. Looking back at our history, they would not be the first Government to say this, nor would they be the first to reap a frightful harvest if the current severe risks were to materialise.
