Modern defence platforms rely on increasingly complex electronic assemblies, which as they mature component availability tightens. The manufacturer often evolves with repair options becoming unavailable and the only traditional support choice is a taxpayer costly full replacement. The partnership between ABI and MoD demonstrates that there is an emerging path. By deploying ABI’s BoardMaster circuit board diagnostic platform alongside their RevEng reverse engineering system and collaborating with MoD DECA -an established structured, in-house capability arm of defence, this enables component-level diagnostics and technical data reconstruction to proactively tackle obsolescence. Across multiple high-value programmes, internal repair and reverse engineering new initiatives have now delivered cost reductions ranging from 94 to 99% compared with the traditional replacement strategies. The savings achieved run into the tens of millions of pounds while simultaneously preserving operational availability.
The collaboration has supported a wide range of mission-critical technologies in:
In each case, component-level diagnostics, using the BoardMaster, enabled engineers to isolate and rectify faults typically where OEMs where unable to help. RevEng was then used to recreate missing or obsolete technical documentation, develop new test procedures, and generate complete support data packs for long-term sustainment. In several programmes, boards originally considered unrepairable were returned to service through innovations in technology using targeted component replacement and reliability improvements in a matter of days. Additionally, reverse engineering eliminated the need for costly architecture redesigns, allowing fleets to continue operating safely and effectively.
While this partnership is established in defence applications, the implications extend to other critical industries facing similar challenges. Energy infrastructure, rail networks, semiconductor manufacturing, and advanced automotive systems are all increasingly dependent on legacy electronic assemblies operating beyond their original operational life. The pressures of obsolescence, documentation loss, and supply chain delays are universal, and the ABI/MoD model demonstrates that in-house diagnostics, supported by reverse engineering and predictive analytics, can unlock drastic lifecycle extensions and cost saving advantages.
In today’s market, electronic sustainment should not be a technical afterthought but a pillar of operational sovereignty. The partnership between ABI Electronics and the UK Ministry of Defence proves that with the right tools, expertise, and leadership, even the most complex legacy electronics can be recovered, maintained, and protected for decades to come. For programme managers and engineers facing the mounting pressures of obsolesacence, this is compelling evidence that provides a golden opportunity for a major strategic overhaul.
