In a defence environment built on precision, reliability and endurance, one escalating threat has the potential to compromise mission-critical operations: electronic component obsolescence.
A recent report from the Financial Times highlights the increasing urgency surrounding legacy semiconductors, as global demand surges for chips built on older process nodes. From the automotive sector to aerospace, industries worldwide are now competing for components once considered outdated. However, in the defence sector, legacy components are not obsolete; they are essential.
Defence systems depend on legacy electronics
Unlike commercial electronics, which are refreshed regularly, defence systems are designed to remain in service for decades. Many platforms still in active use today, including aircraft, missile systems and communications infrastructure, rely on components originally manufactured in the 1980s or 1990s. These parts are often no longer in production, yet remain critical to system integrity.
Modernisation is not always a viable option. The defence sector faces:
- Long and costly qualification cycles
- Strict performance, safety and compliance requirements
- Integration challenges due to highly specialised architectures
When a component becomes unavailable, the impact can be significant. Entire systems may be grounded or retired simply due to a single obsolete part.
Engineering continuity, not just supply
At Force Technologies Limited, we do not source obsolete components. Instead, we engineer bespoke form-fit-function (FFF) replacements that enable our customers to maintain legacy systems without the need for major redesigns or lengthy requalification processes.
Our FFF solutions are developed to precisely match:
- Form: Physical dimensions and packaging
- Fit: Pin compatibility and layout
- Function: Identical or improved electrical performance
These replacements are designed to be plug-in compatible with the original devices, providing a seamless transition that reduces both risk and cost.
You can find out more about our form, fit, function solutions by watching the video available on our website.
Legacy does not mean the end
When a component reaches end-of-life or disappears from the market, it does not have to mean the end of your system. At Force Technologies, we help defence organisations maintain capability with proven, tested and qualified replacements.
Contact us today to find out how our FFF solutions, testing and storage services can support your defence systems for decades to come.
