Plymouth's economic structure is genuinely unusual — health at 12.6% and public administration at 8.8% combine with the naval base to create an automation-resistant core that most cities can't replicate. The military presence alone provides a floor of employment that's determined by geopolitical strategy, not market forces. But retail at 11.2% and manufacturing at 8.4% keep Plymouth in the upper half of the risk table, and the city's relative isolation in the South West means displaced workers can't easily commute to alternative employment centres. Plymouth is a city of two economies: one anchored by institutions that won't automate soon (the Navy, Derriford Hospital, the university), and one made up of exactly the kind of retail and admin work that will. The challenge is that most people work in the second economy.
The Navy is Plymouth's economic life raft, and every time someone proposes cutting the defence budget, the entire city holds its breath. Strip out the military, the hospital, and the university, and what you've got left is a retail park perched on the edge of Devon with a nice view of the sea and a Drake Circus Shopping Centre that smells faintly of existential dread. Retail at 11.2%, manufacturing at 8.4% — the non-institutional economy is a greatest hits of automatable sectors. The Barbican is lovely if you're a tourist; for the people who actually live here and need to earn a living, it's a collection of fish restaurants and gift shops in a city where the average wage would make a Londoner weep. Plymouth's isolation means there's no commuter escape valve — you can't just drive to the next city for work, because the next city is Exeter and it's an hour away. The Ocean City rebrand was a bold attempt to make geography sound like a strategy. The ocean is indeed right there. The jobs, increasingly, are not.
Plymouth's marine sector and naval base are genuinely unique assets — develop a national centre for autonomous marine systems, underwater robotics, and maritime cybersecurity. The university's marine research is well-regarded; scale it into a commercial cluster that creates AI-era jobs rather than losing them. The Devonport dockyard's nuclear submarine maintenance capability has no civilian equivalent — explore whether the decommissioning and nuclear skills can be transferred to civil nuclear energy, which is expanding. The health sector's dominance should be leveraged: partner with Derriford Hospital on health-tech innovation, telemedicine services for the rural South West, and clinical AI applications. Plymouth's isolation is a disadvantage for commuters but could be an advantage for remote workers — invest in digital infrastructure and quality of life to attract location-independent professionals.
They'll talk about the marine tech opportunity at every conference, produce a glossy 'Ocean City Innovation' brochure, and wait for the MOD to keep funding the dockyard. The council will announce a 'Maritime AI Centre' that consists of a desk in an incubator and a part-time coordinator. Someone will propose converting the Royal William Yard into a 'tech campus,' which is already happening except the tech is mostly estate agents and wedding venues. Drake Circus will get a cinema (it did), claim this means the high street is 'evolving' (they will), and continue losing footfall to Amazon (it will). The university will produce marine research that gets published in excellent journals and commercialised by companies based in Southampton. A delegation will visit San Diego's naval tech corridor, return inspired, and discover that Plymouth's budget is roughly 0.5% of San Diego's. The Navy will remain, because it has to. Whether Plymouth builds anything else worth mentioning is the question that gets asked every decade and answered the same way: 'potential.'

The vulnerability score is a weighted average of Plymouth's sector employment shares. Each sector carries an automation risk weight (0.0–1.0) derived from Frey & Osborne's occupational automation probabilities, mapped to SIC sectors via ONS correspondence tables. The weighted average is then normalised to a 0–100 scale. A score of 65.8 means Plymouth's workforce is significantly concentrated in automatable sectors compared to other United Kingdom cities.
