7 Essential Challenges for UK Defence Manufacturers

6 min read | February 18, 2026 03:32 PM AEDT | By Victoria Sokolova (Guest)

The defence industry worldwide is facing a number of challenges these days. For example, the number of orders has increased significantly, and defence manufacturers need to adapt to this increased demand quickly enough. The UK defence manufacturing sector is no exception.  

What other challenges are defence manufacturers facing in the United Kingdom? How can these companies cope with the challenges and ensure smooth execution and timely delivery of defence projects and programmes? What is the role of software tools, particularly PMO software in this process? Let’s figure these issues out in the article.   

Defence projects are mostly complex long-term endeavors that involve the use of innovative technologies and equipment, manipulating sensitive data, and dependence on complex supply chains. All these factors make defence project management extremely challenging.  

In addition, we’ve conducted a survey of European defence companies, the results of which provided us with a deeper understanding of their pain points. Based on these insights and our experience of work with UK defence organisations, we’ve compiled the following list of the issues they are facing.   

Resource management challenges 

Large defence programmes require thousands of skilled engineers, technicians, project managers, and other highly skilled professionals. At the same, the defence industry is suffering from labour shortages for several years so far. This makes it difficult to plan resources for projects and find people with necessary skills quickly enough. In addition, the companies have to address resource conflicts arising from sharing limited resources across projects, which is often easier said than done. Finally, defence manufacturers face challenges with material resources’ availability, which also hampers manufacturing processes and timely delivery of defence programmes.   

Timely project delivery 

Despite the fact that timely project delivery may seem (and should be) the normal state of things, in practice, the delivery of complex defence programmes on time becomes challenging. This becomes especially difficult for large long-term projects lasting for years and even decades. Resource shortages, supply chain issues, high risks, market and geopolitical changes and challenges, bureaucracy and strict regulatory compliance – all these factors can cause delays in projects’ execution.    

Risks and uncertainty 

Risks accompany every defence programme, from geopolitical “surprises” to technology failure. In addition to that, defence manufacturing environment is highly risky by itself. In complex and uncertain multi-project environments and project portfolios with dependencies between projects, it can be really demanding to identify and keep track of all possible risks. Finally, there are lots of uncertainties hidden at every stage of manufacturing project execution, starting from equipment failures to supply chain issues caused by a hurricane; and without proper preparation, these events can disrupt defence manufacturing workflows and timely project delivery.    

Data security concerns 

Defence projects and programmes deal with myriads of sensitive data. What is more, these projects as well as the industry itself is vulnerable to cyber attacks. Finally, increased digitalisation creates additional cyber security risks for defence manufacturing projects. Without taking specific measures and using tools, cyber security issues may jeopardise the success of these projects.    

Supply chain issues 

Industries have been facing supply chain challenges in a greater or lesser degree since the COVID-19 outbreak. These issues are especially pressing for defence companies, as they usually rely on a relatively limited pool of suppliers. This means that any disruptions can negatively affect product quality and lead to delivery delays.  

Regulatory compliance 

The UK defence sector in general and defence projects and programmes in particular should comply with complex legal, safety, and quality requirements. But achieving compliance may require additional resources – time and costs. For example, getting approvals can take more time than expected or become costly, which will also affect project timelines and budgets.   

Increasing demand  

Finally, defence manufacturers are facing the increasing demand for products. While it may seem an advantage to defence companies, it’s a serious challenge, too. Under conditions of human and material resource shortages, tight deadlines, risks and uncertainty, the demand for complying with high quality standards and strict regulations, it’s extremely difficult to meet the increasing demand for products effectively.  

But there’s also some good news. With the right approach and tools, defence companies can complete more work with the same resources, increase portfolio performance, overcome uncertainties and negative risks, and ensure timely project delivery. Jump into the next section to learn the solutions.  

Overcoming the Challenges: Leveraging the Right Approaches and Tools 

Here are some useful steps that will help defence companies overcome the challenges: 

  • Investing in long-term workforce development and upskilling; 
  • Planning resources’ capacity for upcoming projects; 
  • Establishing time and capacity buffers to resist uncertainties and risks; 
  • Using scenario planning before making decisions; 
  • Adopt zero-trust approaches to data management; 
  • Diversifying suppliers and increasing supply-chain visibility; 
  • Leveraging the right project management software tools.  

You can find more insights on overcoming defence project management challenges in our research.  

Let’s now consider the last of the above-listed points in more detail through the example of Epicflow. It’s a PMO software suitable for complex multi-project environments with a shared resource pool and project interdependencies, especially in engineering-driven industries like defence and manufacturing. It has a variety of functions to cope with most of the above-mentioned challenges:  

  • Powerful resource management features: resource allocation, capacity planning, workload balancing, and material resource management.  
  • End-to-end visibility into the project processes and the entire portfolio state. 
  • Risk and bottleneck prediction and elimination; early warnings upon detecting threats in the workflows.  
  • Scenario analysis for informed decision-making.  

As a result, defence companies can get their project-related processes under control, optimise resource utilisation across multiple projects and programmes, and complete their projects on time even under conditions of uncertainties and risks.  

Conclusions   

The UK defence manufacturing sector is facing a complex mix of challenges: they need to balance innovation with regulations, deliver more products under conditions of resource constraints, and cope with risks and uncertainty. These challenges require innovative approaches to managing projects and resources in defence manufacturing. One of the key solutions for these challenges is leveraging the right tools. For example, PMO software like Epicflow can help UK defence manufacturers optimise their available resources, ensure smooth workflow, enhance decision-making, and complete more projects with the same resources.
