From civil aerospace to defense readiness

What to consider when entering the military aviation sector

The demand for military aerospace in Europe is on the rise, opening up new opportunities for established companies in the aviation industry. Branching out from civil into military appears logical. After all, companies across the industry are accustomed to the high quality standards, complex certification processes and long product life cycles typically associated with the defense sector. Experience with advanced technologies and internationally integrated supply chains would seem to offer additional advantages.

But military aerospace is not a typical market entry. Technical expertise and industry experience alone are not enough. Entering the defense sector entails meeting strict requirements that can profoundly impact an organization’s structure, processes, IT and supply chain. Companies that are actively considering ways of entering this market should clarify early on what taking this step would look like for them.

Defense operates under different conditions

For aerospace companies, entering the defense sector starts with the question: How can we become part of a military value chain?

Market entry can be gained through public procurement as well as through existing OEMs, systems providers or other established partners. Before a company even receives its first order, it has to familiarize itself with the particularities of the defense sector: procurement procedures, confidentiality, information security, export controls and other documentation processes. Customer-specific stipulations are also sometimes passed down to subcontractors through multiple tiers.

In addition to its strict requirements, companies need to be aware of the time horizon on which the defense sector operates. Military product platforms are both developed and operated over long periods of time. Delivery capability, spare parts supply, repairability and obsolescence management all remain important well beyond the actual production phase.

Companies preparing to meet the unique conditions of the defense sector should determine early on which markets and value chains are most relevant to them and what the entry requirements are. They also need to assess what changes will have to be made across four key organizational dimensions: product, people, IT and processes.

Product:

Look beyond technical suitability

Entering the defense sector should not be viewed as an extension of existing sales operations but as a transformation of select company capabilities. The first step is to determine which existing products, technologies or manufacturing processes are actually suitable for military applications in a way that goes beyond product fit.

When reviewing products and business model, companies should take into account qualifications, documentation, traceability, product changes and long-term support. They should also clarify internally which adjustments would be required to enter the market at all and which would only be necessary within the framework of a specific program. This reduces the risk of building up capabilities or capacities disproportionate to demand.

People:

Creating new capabilities and responsibilities

Defense readiness is also an organizational challenge. Handling new customer structures, procurement procedures, contractual requirements and security regulations demands specific skills and capabilities. Companies may need to reassign responsibilities or add resources to properly manage classified information and export control as well as bids and contracts. Meanwhile, existing functions – including sales, engineering, procurement, quality and IT – must work together to assess requirements proactively instead of addressing them only after an order is received.

It’s not necessary to build out parallel functions to handle defense business. It’s much more effective to figure out which additional capabilities are needed on top of the ones that already exist, where those new capabilities should be anchored in the organization, and who will be responsible for making decisions.

IT:

Consider security requirements from the start

Information security and confidentiality can directly influence how companies process data and collaborate with customers and suppliers. This does not automatically mean changing up existing ERP, PLM, MES or planning systems. However, companies should understand what kinds of information require special protection, who is authorized to access it, and how this data is exchanged internally or with external partners.

Factors to address early on: access rights, system architectures, isolated environments and secure communication channels. Not addressing these factors as soon as possible – for example, in an ongoing procurement or customer engagement process – can delay market entry.

Processes:

Targeted development of existing aerospace strengths

Established companies are in a position to leverage their deep experience in quality and configuration management, MRO, traceability and documentation – all of which are already part of day-to-day operations in the aerospace industry – to their advantage. Nevertheless, existing processes ought to be reviewed from a defense perspective, specifically processes related to the handling of classified information, the selection and management of suppliers, approvals and changes, and communicating up and down the supply chain. Planning processes also become important when civil and military programs rely on the same materials or resources.

The key question is not, Which processes do I need to rebuild from scratch? What matters most is identifying where existing processes can be purposefully expanded or redesigned.

Defense readiness begins before the first order

Expanding from civil aerospace to defense presents opportunities, but it also requires taking a broad perspective that goes beyond simply trying to match a product to a need. Not every capability needs to be built up immediately. A step-by-step approach is far more manageable. First, understand the starting point and assess how realistic it is to access the market; next, identify critical readiness gaps; and only then, develop the capabilities required for specific customers and programs. This is how companies turn existing aerospace expertise not just into technical capability but into actual defense readiness.
