As the global defence and security industry prepares to gather for DSEI 2025, attention naturally turns to the future — to innovation, integration, and digital transformation. But amid the rapid pace of technological change, there’s a less glamorous, yet mission-critical challenge that demands equal focus: obsolescence.
For OEMs, platform operators and procurement professionals, managing obsolescence is no longer just about sourcing hard to find parts. It’s about sustaining availability, ensuring compliance and safeguarding operational readiness for decades to come.
Why Obsolescence Planning Can’t Wait
Legacy platforms are being asked to do more, for longer. But the components they rely on, especially electronics, often have life cycles measured in years, not decades. With manufacturers regularly issuing end-of-life (EOL) notices and shifting production priorities, the risk of supply chain disruption is growing.
Add to that geopolitical uncertainty, export controls, and increasing complexity in global logistics and the picture becomes clear: without a structured approach to obsolescence, even the most advanced systems are vulnerable.
Obsolescence doesn’t always strike loudly, sometimes, it creeps in slowly. And by the time a critical item becomes unavailable, mitigation options may be limited, costly, or non-compliant.
The Real Cost of Obsolescence
The impact of unmanaged obsolescence is tangible:
-
Grounded fleets awaiting replacement avionics modules no longer in production
-
Soaring costs for last-minute purchases of obsolete components
-
Programme delays due to requalification of substitute parts
-
Reduced operational availability and rising through-life support costs
These aren’t theoretical risks by the way, they’re real outcomes already affecting programmes across the defence and aerospace sectors.
Proactive Obsolescence Management: What Good Looks Like
Defence organisations that take obsolescence seriously do five things differently:
1. Embed Lifecycle Intelligence Early
Smart planning begins at system design stage. Component selection should take into account lifecycle forecasts, vendor roadmaps, and supply chain resilience, not just performance and cost.
2. Use Predictive Monitoring Tools
Modern obsolescence management relies on timely data. Monitoring systems track EOL alerts, part availability and obsolescence trends, allowing teams to act early, not react late.
3. Develop Integrated Obsolescence Management Plans
An Obsolescence Management Plan (OMP) shouldn’t be an afterthought. It should sit alongside reliability, ILS and procurement strategies, reviewed and updated throughout the programme lifecycle.
4. Plan for Last-Time Buys Intelligently
Forecasting demand and procuring in advance of obsolescence can save money and time, but only if done in a controlled, evidence-based way, with proper inventory management in place.
5. Work with Trusted Obsolescence Specialists
Engaging a partner with experience in defence obsolescence, including ITAR, REACH and defence quality standards, ensures any substitutions, redesigns or sourcing efforts meet both compliance and performance requirements.
CMCA(UK): Your Obsolescence Partner of Choice
At CMCA(UK), we specialise in helping defence and aerospace customers manage obsolescence risk with precision and confidence. From component engineering and technical assessments to global sourcing, storage and managed service support, we offer a full-spectrum solution, tailored to the demands of long life, mission critical platforms.
Whether you’re sustaining a legacy fleet or designing next-generation capabilities, our expert team works alongside yours to secure supply chain continuity and reduce lifecycle cost.
Looking Ahead to DSEI 2025
The conversations at DSEI will be dominated by AI, autonomy and advanced manufacturing. But all innovation rests on a stable foundation – and that foundation is the availability of the components that keep critical systems operational.
Organisations that treat obsolescence planning as a strategic asset, not a logistical afterthought, will be the ones best placed to meet the demands of tomorrow’s battlespace.
Don’t let obsolescence determine your operational future. Plan now. Partner wisely.
