The strongest case is for programmes that meet a clear security need while building productive skills, research, infrastructure, or industrial capacity. If employment targets drive procurement, workers are pulled from more productive uses, or costs crowd out higher-value public investment, the trade-off can outweigh the gains.
Does defence spending create jobs?
Yes. Defence procurement can support military and contractor jobs, as well as work in construction, maintenance, logistics, engineering, and supplier firms. Infrastructure projects can also support direct and indirect employment. Domestic sourcing may keep more of that activity within a country and sustain industries important to security, such as advanced manufacturing, aerospace, steel, AI, and quantum technology.

But “jobs supported” is not the same as “net new jobs created.” A multiplier estimate counts activity associated with spending; it does not, by itself, establish that every job is additional to the economy. Some workers may move from other industries, some inputs may be imported, and the benefits depend on whether domestic firms have the capacity and workforce to deliver the work. Jobs may also differ in skill, duration, location, and dependence on continuing government contracts.
What do government estimates show?
Government figures illustrate the scale of activity defence industries can support, but they cover different measures and should not be treated as directly comparable forecasts of net employment.
#1 Best Overall
| Source and geography | Reported figure | What it measures |
|---|---|---|
| Government of Canada, 2022 | 81,000 jobs and $9.6 billion in GDP | Canada’s nearly 600 defence firms contributed these amounts in 2022, according to the government’s Defence Industrial Strategy. |
| Government of Canada, current Defence Industrial Strategy | Up to 125,000 additional jobs | A target associated with expanding Canadian defence capacity, not a guarantee of net jobs delivered. |
| Government of Canada, 2026 | About $59 billion in defence-infrastructure spending over ten years; approximately 340,000 direct and indirect jobs | An indicative estimate based on Statistics Canada multipliers. It is not a count of guaranteed net new jobs. |
| UK Government, Invest 2035 | Around 434,000 jobs; 67% of defence spending with UK industry and commerce goes outside London and the South East | The first figure is jobs supported by government defence spending; the second describes the regional distribution of UK defence spending with industry and commerce. |
The Canadian and UK figures reflect their own economies, definitions, and policy contexts. They are examples, not universal benchmarks for what a defence programme will do elsewhere.
Can national security spending grow the economy?
It can, particularly when spending develops research, infrastructure, technical skills, or suppliers that also contribute to civilian productivity. However, economic spillovers are possibilities, not automatic returns on every defence dollar. The European Central Bank’s 2026 analysis cites a model estimate that raising defence spending by 1% of GDP could increase total factor productivity by 0.3% over the long run, primarily through public-research-and-development spillovers. That is a long-run estimate, not an observed or guaranteed result.

The ECB also estimates that bringing European defence R&D up to the US rate could raise EU GDP by 0.5% in the long run, assuming defence-related R&D has the same economic effect as government-funded R&D. This is a scenario estimate: its result depends on the assumption and the R&D catch-up occurring.
The type of spending matters. Research and infrastructure may build knowledge or assets with uses beyond a single procurement programme. Personnel spending supports military capability and employment, but it does not necessarily create the same productivity spillovers. For any category, the relevant question is what capability or productive asset the spending buys—not simply how much is spent.

Why is economic strength part of national security?
Security depends on more than weapons and personnel. Economic growth, skilled workers, science and technology, innovation, trade resilience, and the capacity to raise revenue all affect a country’s ability to maintain security over time. Supply-chain resilience and a healthy industrial base can help sustain production and respond to disruption; fiscal capacity determines how much a government can fund without weakening other priorities.
The Congressional Research Service sums up the relationship this way: “In national security, the economy is both the enabler and the constraint.” A strong economy can support security capabilities, while an overextended budget or weakened productive base can limit them. Canada’s Defence Industrial Strategy similarly says, “Our national security and our economic security go hand in hand.” The two are linked, but that does not mean every programme that claims a security purpose also strengthens the economy.

When can job creation become a costly trade-off?
- Procurement serves employment rather than capability. A project chosen to protect a political constituency or preserve a particular contractor’s workforce may provide less security capability per dollar than an alternative.
- Jobs are counted without considering displacement. A multiplier-based estimate may include work shifted from another sector, rather than employment added to the economy overall.
- Labour and materials are scarce. Defence projects may compete with civilian employers for workers, suppliers, or construction capacity. The economic effect depends on what activity is displaced as well as what is funded.
- Benefits are temporary or concentrated. A large headline total can obscure short project durations, reliance on continued contracts, or gains concentrated in a few regions while taxpayers elsewhere share the cost.
- Costs weaken other sources of resilience. If a programme crowds out higher-return investment or strains the government’s ability to fund essential priorities, it may undermine economic strength that also supports security.
How should governments weigh security against employment?
A sound decision starts with the security requirement, then tests whether the economic case strengthens or weakens the choice. Job creation can be a legitimate benefit, but it should not substitute for evidence that the programme meets a real mission need.
- Identify the capability. What threat, mission, or supply-chain vulnerability does the spending address? Specify what the programme is expected to deliver.
- Estimate net employment, not just supported jobs. Separate direct jobs from indirect jobs, state the assumptions behind any multiplier, and assess whether the workers and resources would otherwise be employed elsewhere.
- Assess durability and quality. Consider whether work builds transferable skills and lasting capacity or depends on a temporary project and future contract renewals.
- Map who benefits and who pays. Examine regional distribution alongside the tax burden and opportunity cost borne by households and other public services.
- Test the innovation and productivity case. Identify plausible civilian uses for research, infrastructure, and technical capabilities. Treat projected spillovers as estimates, not guaranteed returns.
- Compare alternatives and affordability. Consider whether infrastructure, education, health, basic research, or civilian industrial policy would deliver greater employment or resilience, and whether the defence programme is sustainable within the public finances.
Are defence jobs worth the cost?
They can be, when the spending is justified by a clear security need and the resulting capability is worth its full cost. The economic case is stronger when the programme also builds durable skills, productive infrastructure, research, or a resilient industrial base. It is weaker when employment totals are presented as guaranteed net gains, procurement is chosen to preserve jobs at the expense of capability, or costs displace more valuable work and investment.

For households, the headline number of jobs is therefore only one part of the decision. The fuller test is whether the public money buys needed security, creates worthwhile and reasonably durable economic benefits, distributes those benefits fairly, and remains affordable alongside other priorities.
