The Wage of War: Promoting Major Innovation

The wage of war has two meanings. It is the pay packet handed to the soldier, sailor or aviator who serves. It is also the price the nation pays when conflict exposes years of peacetime drift, false economy and delayed investment. Britain’s recurring problem is not only that defence is expensive. It is that we too often fund capability late: after we have underinvested in people, experimentation, testing and the mundane business of making new systems safe, usable and sustainable. The result is that we end up paying major prices for recruit-level preparation.[1]

To keep that argument clear, I use the fictional character of “Major Innovation”. He is not a mascot for novelty and he is not an excuse for breathless technology talk. He is a way of thinking about disciplined promotion. Every capability begins as a recruit: interesting, energetic and unproven. It should become a lieutenant only after early experimentation, a captain only after hard trials with real users, and a major only when it is integrated into doctrine, training, maintenance and force design. When Britain tries to buy the major before it has trained the recruit, the bill arrives later and usually with interest.

1. The soldier is the baseline

Any argument about innovation that begins with platforms rather than people is already off course. The British Army careers site now states that new recruits begin on £26,334 a year from the start of training, and the 2025 pay round added a further 4.5% above-inflation rise for most Armed Forces personnel.[2] Those facts matter, but they do not settle the question of whether service feels properly valued.

The 2025 Armed Forces Continuous Attitude Survey paints a more complicated picture. Just 34% of personnel said they were satisfied with their basic pay. Only 42% were satisfied with service life in general. Over three quarters of personnel—78%—live in service accommodation during the working week. Yet only 34% were satisfied with responses to requests for maintenance or repair work in Service Family Accommodation, and only 51% were satisfied with the overall standard of that accommodation.[3] The Strategic Defence Review acknowledged that personnel must be at the heart of future defence and committed at least £7 billion this Parliament to military accommodation, including over £1.5 billion in new funding for rapid work on forces family housing.[4]

That is not a side issue. It is the first test of seriousness. A state that cannot keep faith with the daily life of its people will rarely make disciplined decisions about the early life of new capability. Before Major Innovation reaches the field-grade ranks, he must survive basic training. If the institution treats the human foundations of military service as an afterthought, it will tend to do the same with experimentation, user trials and the other unglamorous tasks that turn an idea into something soldiers trust.

2. Bigger budgets will not solve the wrong problem

The United Kingdom is not standing still on defence spending. The House of Commons Library says the UK spent £60.2 billion on defence in 2024/25 and expects spending to rise to £62.2 billion in 2025/26 and £73.5 billion in 2028/29. The same briefing notes that recent spending growth has been weighted toward capital budgets rather than day-to-day resource spending.[5] In NATO terms, the UK is expected to spend 2.4% of GDP on defence in 2025, and the Government has committed to reach 2.5% by 2027.[6]

Those are serious sums, but the shape of spending matters at least as much as the size of spending. A force can buy more metal, software and infrastructure without proportionately improving readiness, training, maintenance or the daily experience of the people expected to fight with that equipment. This is one of the central warnings in the current debate. More money is coming into defence. The question is whether it will create more real combat power, or simply a larger budgetary surface area on which old habits can continue.

That is why peacetime matters so much. War forces acceleration; peace should allow preparation. In a healthy system, peacetime is the academy in which Lieutenant Innovation learns his trade. It is when the department can afford to run prototypes, expose flaws early, test concepts against doctrine and train operators honestly. When peacetime becomes a period of deferment instead, Britain arrives at the next crisis with a shopping list rather than a force design.

3. Britain’s habit of paying late

The evidence for late funding is now too strong to dismiss as bad luck. The National Audit Office concluded that the Equipment Plan 2023–2033 was unaffordable, with forecast costs exceeding the available budget by £16.9 billion.[7] The Strategic Defence Review responded by promising a new Defence Investment Plan that would be deliverable and affordable, consider infrastructure alongside capabilities and replace the old-style Equipment Plan.[8] That is the right ambition, because the wrong lesson from current failures would be that Britain simply needs to spend more quickly. The deeper lesson is that Britain needs to spend in sequence.

That sequence is the real point of Major Innovation. Recruit-stage innovation is exploration: small budgets, clear hypotheses, rapid feedback and permission to fail early. Lieutenant-stage innovation is the prototype: a limited command in which technical promise is confronted with user behaviour, environmental stress, safety demands and training burden. Captain-stage innovation is the trialled capability: proven against criteria such as maintainability, interoperability and whether troops actually want to use it. Only then should it become Major Innovation: a fielded capability embedded in the wider institution.

When the sequence is reversed, prestige outruns competence. Programmes become too large to fail politically, but still too immature to succeed operationally. Warning signs are rationalised rather than resolved. Supporting systems are treated as follow-on problems. The nation then pays twice: first for delay, and second for the urgent stopgaps needed when the promised capability does not arrive on time.

The land environment makes the pattern especially clear. In 2021 the Defence Committee said repeated failures in British armoured vehicle procurement had already led to at least £321 million being spent on programmes later cancelled, alongside a further £2.8 billion spent filling an urgent capability gap.[15] That is a classic late-funding penalty. Money that could have been used to develop a coherent capability path was instead consumed by abandonment and emergency substitution.

That history also explains why transparency matters. In January 2026 the Public Accounts Committee and Defence Committee jointly warned that continued delay to the new Defence Investment Plan, long promised for autumn 2025, risked sending damaging signals to adversaries.[16] Their point was not only political. Delayed choices preserve the appearance of flexibility, but they can also freeze procurement logic and postpone the disciplined acceptance that some programmes must change, shrink or stop.

4. Procurement failures as evidence

Nimrod MRA4 remains the clearest symbol of sunk cost without delivered capability. The National Audit Office recorded that the programme was cancelled in 2010 after a 14-year procurement history in which more than £3.4 billion had already been spent.[9] The lesson was not merely that one programme went wrong. It was that repeated compromise and delay can make recovery harder, not easier. By the end, Britain had spent heavily without obtaining the capability it expected.

Ajax is different, and in some ways more instructive, because it is not a simple cancellation story. In 2022 the National Audit Office said the department had not demonstrated value for money on the £3.167 billion already spent through the contract.[10] The programme then appeared to move forward, with initial operating capability announced in November 2025. But in January 2026 the Minister for Defence Readiness and Industry told Parliament that 35 service personnel had reported symptoms resembling those caused by noise and vibration during a training exercise, and that he was pausing the declaration of initial operating capability until the concerns had been resolved.[11] Ajax therefore shows something more uncomfortable than a failed purchase: it shows how difficult it is to restore confidence once the basics have been mishandled.

Watchkeeper illustrates a third failure mode: technology moving faster than programme rhythm. By 31 May 2023, the MOD said it had spent £1.351 billion on whole-life costs for Watchkeeper, including £1.114 billion on procurement.[12] In November 2024 the Government announced that the system would retire from March 2025 because drone technology had advanced rapidly, particularly under the pressure of war in Ukraine.[13] Yet by February 2026 Parliament was told that Watchkeeper would now remain funded through to March 2027, with £115.886 million allocated over the period from November 2024 to March 2027 while Project Corvus is delivered.[14] In other words, the system became old before the programme cycle around it had properly finished.

These cases are not identical. Nimrod was cancelled. Ajax is a troubled recovery. Watchkeeper is an expensive bridge to replacement. But they point in the same direction. Britain repeatedly struggles to create a protected career path for innovation. Instead of training and promoting it step by step, we tend to lurch from underfunded incubation to overcommitted acquisition.

5. What promotion should look like in practice

The answer is not to become hostile to innovation. It is to become more professional about it. The coming Defence Investment Plan should therefore do four things. First, it should protect recruit-stage budgets for experimentation from being raided whenever larger programmes come under pressure. That is where cheap learning happens. Second, major procurement decisions should require genuine user evidence, not only industrial assurance or schedule optimism. Third, enabling functions—training, spares, infrastructure, data, safety cases and support contracts—should be funded as part of capability from the beginning, not discovered later as unaffordable extras. Fourth, Parliament needs clearer visibility of performance, affordability and slippage so that embarrassment is not the main trigger for honesty.

The Major Innovation metaphor is useful here precisely because it is conservative in the best military sense. Promotion is not a gift; it is recognition earned through demonstrated competence. No sensible chain of command would send an untrained recruit to command a company simply because the strategic situation had become urgent. Yet that is roughly how Britain sometimes behaves in acquisition. We ask immature capabilities to do senior work, then act surprised when they fail under operational weight.

This also helps explain why personnel policy and innovation policy should not be separated. Soldiers are not just recipients of capability. They are the judges who decide, often brutally and correctly, whether equipment is useful, safe and worth the burden it imposes. A procurement system that marginalises users until the late stages is not only disrespectful. It is inefficient. Major Innovation cannot be promoted on PowerPoint alone; he needs field reports, instructors, maintainers, sceptics and hard evidence.

Conclusion

The wage of war is therefore more than a number in a Treasury table. It is the pay of the junior soldier. It is the condition of the family home. It is the budget line for readiness. It is the emergency bill created when a long-delayed programme still cannot do what was promised. Britain is right to spend more on defence in a more dangerous world. But if the extra money is absorbed chiefly by late, overgrown programmes, then the country will keep paying major prices for recruit-level preparation.

If, however, Britain uses this period to fix the lived experience of service, protect disciplined experimentation and promote new capability only when the evidence justifies it, then Major Innovation will have served his purpose. He will not be a slogan. He will be a habit of mind. And that is how innovation should be treated in defence: not as a one-off purchase, but as an officer whose advancement depends on training, judgement and performance.
