The government has finally published its long-delayed Defence Investment Plan, and for anyone building a career in the defence sector, the headline number to watch isn’t the funding total. It’s the jobs.
The plan in brief
On 30 June, the Prime Minister confirmed £15 billion in new funding for defence over the next four years, with a particular focus on drones, autonomous systems and artificial intelligence. Speaking at the Malloy Aeronautics site, where military drones are built and shipped to Ukraine, the government said the plan would strengthen the economy by creating almost 60,000 jobs, with spending directed towards backing British workers, businesses and innovators wherever possible.
The plan itself frames job creation as central to its purpose rather than a side effect. The government expects the investment to boost productivity and, by 2029/30, support nearly 60,000 additional UK direct and indirect jobs compared with 2023/24, alongside a boost to UK defence exports. Alongside this, ministers announced a new £50 billion Defence Export Facility, described as the largest expansion of UK Export Finance support in its hundred-year history, intended to help British defence firms win contracts overseas.
Some of the biggest single commitments sit in the nuclear enterprise. The plan sets out over £20 billion of additional investment in the Defence Nuclear Enterprise over the next four years compared with the previous four, covering new submarines, warheads, a nuclear fuels programme and work on a Dreadnought successor. A further £70 million has been earmarked for veterans’ support through the Office for Veterans’ Affairs.
Not everyone is convinced it goes far enough
Reaction to the plan has been mixed, and much of the criticism centres on whether the money is real, and whether it’s enough.
The Institute for Fiscal Studies pointed out a significant gap in the funding. The government has committed to an average of £3.8 billion in extra funding per year over the next four years, but has not set out how it will pay for roughly a third of that increase, an average of £1.2 billion a year, leaving the decision to this year’s Budget.
Some of the offsetting savings have also drawn scrutiny. A government document showed that £4 billion would come from cutting long-term public investment and a further £2.8 billion from reductions to transport and energy projects, with an additional £4.7 billion still marked as “to be funded at Budget 2026”. Former Royal Navy commander Tom Sharpe was blunt about the implications for the fleet, describing the plan as cost-cutting by another name rather than genuine investment, and calling the proposed hybrid navy chronically underfunded.
Opposition politicians went further. Liberal Democrat leader Sir Ed Davey called the plan late and underfunded, describing that as unforgivable, and noted that Britain is set to lag behind NATO allies such as Germany and Sweden on defence spending as a share of GDP.
Independent analysts have broadly agreed the plan is real, but modest relative to ambition. The IISS noted that more cash is coming over the decade the plan covers, but exactly how much is still mired in debate, as is whether it will be sufficient, with all three services appearing to have won some battles and lost others. It also flagged that the funding trajectory is likely to follow a “hockey-stick” pattern, with much of the increase falling in the later years of the plan rather than arriving immediately, something NATO’s Secretary General has previously cautioned against.
What this means if you’re building a defence career
For jobseekers and employers in the sector, three things stand out from the noise around funding levels:
- The direction of travel is unambiguous even if the pace is contested. Whether the increase is judged adequate or not, every serious analysis agrees defence spending is rising in real terms and will keep rising into 2029/30. That’s a multi-year hiring signal, not a one-off announcement.
- The jobs being created skew towards specific, high-value skills: autonomous systems and drone engineering, AI and cyber, nuclear enterprise roles, and export and procurement expertise as the new Defence Export Facility and National Armaments Director Group get built out. Apprenticeships and skilled trades in shipbuilding and manufacturing remain part of the picture too, particularly around the nuclear deterrent and hybrid naval programmes.
- The funding uncertainty itself is worth watching. With a portion of the plan still unfunded ahead of this year’s Budget, and a change of Prime Minister expected within weeks, some programmes could be reshaped again before contracts and hiring plans are finalised. Anyone tracking opportunities in this sector should expect further announcements, not a settled position, over the coming months.
