UK Defence Spending Surge: The Careers Hiring Now as Britain Ramps Up Military Investment

HMS Dragon is heading to Cyprus. The G7 has pledged “necessary measures” to secure energy supplies. Rachel Reeves has warned of sustained economic impact from the Iran conflict. Behind these headlines sits a less visible but equally significant shift: the UK is spending more on defence than at any point since the Cold War.

The government confirmed defence spending will reach 2.5% of GDP by 2027, up from 2.1% in 2024. In cash terms, that is an additional 8 billion pounds per year flowing into military procurement, cyber capabilities, shipbuilding, and intelligence infrastructure.

For anyone considering a career move, this spending surge is creating demand across a range of occupations that extends far beyond the armed forces themselves.

The scale of the UK defence workforce

The Ministry of Defence directly employs approximately 260,000 people: 150,000 regular armed forces personnel and 110,000 civilian staff. But the defence sector’s true employment footprint is vastly larger.

According to ADS Group, the trade body for UK aerospace, defence, security, and space industries, the wider defence sector supports approximately 440,000 jobs across the UK. This includes employees at prime contractors like BAE Systems, Rolls-Royce, Babcock, and Thales, as well as thousands of SMEs in the supply chain.

ONS business survey data shows that defence-related manufacturing and engineering employment is concentrated in specific regions: the South West (Bristol, Bath), North West (Lancashire, Barrow-in-Furness), Scotland (Glasgow, Fife), and the East of England (Stevenage, Chelmsford).

Where the money is going

The spending increase is not evenly distributed. Defence procurement priorities for 2026-2028 are concentrated in five areas, each with distinct career implications.

Naval shipbuilding and submarines. The AUKUS submarine programme and Type 26 frigate programme are absorbing billions. BAE Systems in Barrow-in-Furness has hired over 4,000 new workers since 2023 and plans to recruit thousands more. Babcock in Devonport and Rosyth is expanding its workforce for the Dreadnought nuclear submarine programme.

Roles in demand: naval architects, marine engineers, welders, pipefitters, project managers, quality assurance engineers. Starting salaries for qualified welders in submarine construction now exceed 35,000 pounds, with experienced hands earning above 50,000 pounds.

Cybersecurity and intelligence. GCHQ, MI5, and MI6 have collectively expanded their recruitment by over 30% since 2024. The National Cyber Security Centre is funding new programmes to build domestic cyber capability. Private sector contractors supporting government cyber operations are hiring aggressively.

Roles in demand: penetration testers, security analysts, threat intelligence specialists, software engineers with security clearance. ONS earnings data shows information security professionals commanding median salaries of 55,000 to 70,000 pounds, with cleared specialists earning significantly more.

Aerospace and unmanned systems. The conflict in Iran has underlined the military importance of drone technology, electronic warfare, and air defence systems. UK companies developing these capabilities are scaling up. Leonardo in Edinburgh and Luton, MBDA in Stevenage, and dozens of smaller firms are recruiting.

Roles in demand: aerospace engineers, systems engineers, software developers specialising in embedded systems, AI and machine learning engineers working on autonomous platforms.

Ammunition and munitions. BAE Systems has reopened and expanded munitions manufacturing in Washington, Tyne and Wear, and Glascoed, South Wales. After decades of decline, UK ammunition production is scaling up to meet both domestic and NATO demand.

Roles in demand: chemical engineers, production operatives, logistics specialists, health and safety managers. These roles have seen salary increases of 10-15% over the past 18 months as manufacturers compete for workers.

Satellite and space. The UK Space Command, established in 2021, is growing. The MOD’s Skynet 6 programme and investment in space domain awareness are creating new roles in an emerging sector.

Roles in demand: satellite engineers, RF engineers, orbital mechanics specialists, ground station operators.

Salary data across defence careers

ONS Annual Survey of Hours and Earnings data shows that defence-adjacent occupations consistently pay above national medians. Selected figures for 2025:

Engineering professionals in manufacturing: median salary 45,800 pounds, with the top quartile earning above 58,000 pounds.

IT and telecommunications professionals: median 44,200 pounds, rising to 62,000 pounds at the upper quartile.

Skilled metal and electrical trades: median 36,400 pounds, with defence sector premiums of 15-20% above civilian equivalents due to security clearance requirements and specialised skills.

Project managers in engineering: median 48,500 pounds, with defence sector roles regularly exceeding 55,000 pounds.

The security clearance premium is significant. Workers holding Developed Vetting (DV) clearance, required for the most sensitive programmes, can expect salaries 20-30% above equivalent non-cleared positions. The clearance process itself takes 6-12 months, creating a natural barrier that sustains higher wages for those who hold it.

The regional employment effect

Defence spending is one of the few areas of UK industrial policy that directs significant investment outside London and the South East.

The Type 26 frigate programme supports an estimated 4,000 jobs on the Clyde. The submarine programme sustains Barrow-in-Furness, a town where BAE Systems is the dominant employer. MBDA’s missile development in Stevenage, Leonardo’s helicopter and electronics operations in Yeovil and Edinburgh, and Rolls-Royce’s submarine reactor facility in Derby all anchor high-skilled employment in regions that have lost manufacturing jobs over the past four decades.

CareerMetrics regional salary data shows that defence manufacturing roles in these areas often pay within 10-15% of equivalent London salaries, while local living costs are 30-50% lower. A systems engineer earning 48,000 pounds in Stevenage or 45,000 pounds in Bristol has comparable or better purchasing power than one earning 60,000 pounds in London.

Career switching into defence

The defence sector has historically been difficult to enter mid-career, with employers preferring candidates with existing security clearance and sector experience. That is changing.

Skills shortages are forcing defence companies to recruit from adjacent industries. The most common transition paths, based on MOD workforce data and recruiter surveys, include:

Automotive to defence manufacturing. The decline of UK automotive production has released thousands of skilled engineers and production workers. Defence manufacturers are actively recruiting from this pool, with retraining programmes typically lasting 3-6 months.

Tech to cyber defence. Software developers, data engineers, and cloud architects from commercial technology companies are moving into government-adjacent cyber roles, attracted by the security clearance premium and the stability of government-backed contracts.

Oil and gas to naval engineering. The structural decline of North Sea oil and gas has created a pipeline of experienced engineers with transferable skills in marine systems, pressure vessels, and safety-critical design. Submarine and surface ship programmes are absorbing these workers.

Construction to infrastructure. The MOD’s estate modernisation programme, worth over 4 billion pounds, requires civil engineers, quantity surveyors, and facilities managers with experience in large-scale building projects.

The long-term outlook

Defence spending commitments tend to be more durable than other areas of government expenditure. The AUKUS submarine programme alone runs to the 2050s. The Dreadnought programme is contracted through the 2030s. Cyber and space capabilities require ongoing investment regardless of whether the current conflict continues.

This is not a short-term hiring spike. The careers being created by the defence spending increase are underpinned by multi-decade procurement programmes and cross-party political support for higher military budgets.

For workers in manufacturing, engineering, IT, and project management, the defence sector offers something increasingly rare in the UK economy: long-term contracts, defined career progression, above-median salaries, and geographic distribution outside London.

CareerMetrics tracks salaries across 520 UK occupations including many defence-relevant roles. The Salary Forecast tool models how sector-specific demand trends affect earnings trajectories. Compare Paths lets you evaluate a move from a civilian career into a defence-adjacent role, comparing salary, progression, and regional cost of living side by side.

In an economy where energy shocks, trade disruption, and geopolitical uncertainty are eroding real wages across most sectors, defence is moving in the opposite direction. The data suggests it will continue to do so for years to come.
