Mission Engineering Under Constraint: The Apollo 13 Principle in UK Battery Innovation

During the Apollo 13 mission, engineers in Houston were given one impossible brief:

Bring three astronauts home alive, using only the parts already on the spacecraft.

No extra budget.
No extra time.
No new hardware.

They had constraints, a deadline, and no option to drift.

One of the defining engineering moments in that mission was adapting a square lithium hydroxide canister to fit a round receptacle, using only materials already on board. The solution required disciplined reconfiguration of existing components under time pressure.

Working in UK battery innovation increasingly feels similar, not because the mission is doomed, but because the mission is real:

Constrained funding, constrained STEM capacity, constrained time, and yet the work still has to land.

From the outside, the UK appears to be a textbook innovation success story.
Inside the system, after the recent Battery Innovation Showcase, the question I keep returning to is more practical than celebratory:

If we are serious about the UK becoming a genuinely competitive battery industry on the world stage and serious about delivering net zero, are we structuring our STEM and engineering system to deliver industrial strategy missions under real-world constraints?

From the vantage point of Global Solutions, PAK Engineering and EPT, my answer is simple:

Yes, if we treat constraints as part of the design brief, not something we apologise for.

The Quiet Question in the Room: Who Gets to Build?

On stage at the battery innovation event, the focus was exactly what you’d expect: chemistries, manufacturing, investment, geopolitics.

But in the breaks, coffee queues, corridor conversations, and side discussions, the topic kept returning to something more foundational:

Who, exactly, is going to build all this — and where are they going to work?

The UK is not short of ideas.
Nor are we short of talent on paper.

What matters is whether the system provides mechanisms to support the acquisition of talent into the parts of the industry that need it most, early enough to make a difference.

From where I sit, the dynamic is straightforward:

• Public investment grows STEM capability through schools, universities, and research programmes.
  
• Large organisations sit closest to that pipeline, with structured pathways that draw strongly from it.
  
• SMEs and scale-ups typically sit further from that pipeline, yet are still expected to deliver first-of-a-kind systems at pace, frequently under tightly constrained programme timelines.

There is nothing inherently wrong with that structure. But it does mean that the UK’s innovation engine, its SMEs, does not always have sufficient access to young engineering talent.

New pathways need to be deliberately designed to facilitate that access, enabling SMEs to make full use of that UK-based capability.

Otherwise, we default to a model in which experienced engineers leave large organisations to start their own ventures, while younger engineers miss the opportunity to learn in smaller, high-constraint environments.

And it is precisely those constrained environments, financial, technical and timeline-driven, that build adaptability and lateral problem-solving capability.

In essence, this is not a question of whether the UK produces engineers.
The question is whether we are enabling them to operate where delivery pressure is highest and capability is built fastest.

What Constraints Look Like in Practice

“Constraints” aren’t a policy phrase for me; they are the daily reality of delivery.

• Time and bandwidth
  Delivery programmes create momentum, and momentum needs capacity. When timelines are fixed and complexity is real, what makes the difference is having enough skilled hands in the room at the right moments.
  
• Talent mobility and timing
  When specialist capability is needed, timing matters. Delays don’t stop the work; the work simply gets redistributed within the existing team. That makes early access to capability a force multiplier.
  
• Funding cycles and programme windows
  Timelines are not only technical. They are often shaped by fixed public funding cycles, in which budgets must be allocated within defined spending periods in line with programme requirements. That structure becomes part of the operating environment for first-of-a-kind delivery.
  
• Competing for the best graduates
  SMEs can offer frontline work and steep learning curves. Larger organisations can offer perceived security and established graduate structures. Both play a role, but it means SMEs need clearer, faster ways to access top young engineers.

None of these blocks innovation.

It simply defines the mission profile:

Limited parts. Clear deadlines. High standards.

Which is why the Apollo 13 principle keeps resurfacing.

STEM Architecture, Not STEM Slogans

The UK is starting to take clean-energy skills seriously, and that’s welcome.

But there’s a distinction worth making:

It’s not enough to grow the pipeline.

We have to design the architecture that routes capability to delivery.

How is the system designed so that the right engineers reach the right missions, fast enough?

If we want UK innovation to become UK capability, we need more mechanisms that connect early-career engineers to real delivery environments, not years later, but now.

How We Work: Projects as STEM Pathways

At Global Solutions, alongside PAK Engineering and EPT, we’ve stopped treating talent as a secondary topic.

Every serious project has a built-in pathway, because capability is not a by-product. It is an output.

What that looks like in practice:

• Young engineers on live missions
  EPT and PAK routinely utilise young engineering graduates, not as observers but as contributors working under supervision on real design, modelling, analysis, integration, and deployment learning.
  
• Access to the best early-career talent
  We want more of it, and not just “more graduates”, but access to the strongest young engineers in the field, with clearer routes into meaningful work earlier in their careers.
  
• Constraint as part of the training
  Our teams learn under real-world limits: time, budget, uncertainty, and complex stakeholder environments. That produces a different kind of engineer, someone who can deliver under constraint, not only design under ideal conditions.

For us, every project is both a technical experiment and a capability-building system.

Success is measured in prototypes and deployments, and in the skills that remain in the ecosystem when the project ends.

A Small Lever Worth Testing at Scale: Secondments That Move Engineers, Not Just Money

After the battery innovation event, one practical idea kept returning because it is immediately actionable:

What if we moved engineers, not just money?

Here is a model worth piloting on a scale:

• Early-career engineers in large organisations spend defined periods working inside SMEs on scoped innovation work.
  
• Their base employment remains stable, while project funding supports the secondment structure and supervision.
  
• IP and confidentiality are handled through standardised agreements, so everyone knows where they stand.

The value is obvious:

• SMEs gain fast access to the capability at the point of delivery.
  
• Large employers gain engineers who return with stronger systems thinking and frontline learning.
  
• Funders see faster delivery and stronger resilience across strategic projects, without having to wait for a perfect pipeline to appear.

It’s an Apollo 13-style answer:

We already have parts in the system.
We just need to configure them for the mission.

Turning Constraints Into Capability

One of the clearest realisations from the last year is this:

Constraints are not only obstacles but also part of the invention.

Like Apollo 13, our engineers are being asked to deliver with a limited set of parts.

We don’t have the luxury of waiting for the perfect workforce to arrive before we build.

What we do have is the ability to design projects as STEM pathways, not just work packages; widen access to excellent young engineering talent into the missions that need it; and pilot secondment and rotation models that move capability to where delivery pressure is highest. In that sense, delivery capacity is not a side issue; it is a strategic infrastructure for UK battery innovation.

The UK does not lack ideas, ingenuity, or ambition.

The opportunity now is to build the talent pathways that enable those ideas to become real capability, at speed, under constraint, and with confidence.

That is a discussion worth having openly, because strengthening how talent moves through the system may be one of the highest‑leverage moves available to UK battery and clean‑energy innovation.

If leaders in large organisations, or colleagues within Innovate UK and related programmes, recognise this dynamic, then this is a conversation worth having openly.

Because strengthening how talent moves through the system may be one of the most practical levers we have.

If this resonates with your experience of delivering battery or clean‑energy projects under real‑world constraints, you’re not alone.

These questions about how engineers move through the system, who gets to build, and how we turn talent into delivery capacity are still too rarely discussed openly.

I’d like that to change. If you’re interested in comparing notes or exploring how we might strengthen these talent pathways together, I’d welcome a conversation on LinkedIn.
