War and electronics design: the industry's new reality

For years, defense electronics relied on relatively stable logic. Systems were designed for specific threat models, tested in controlled conditions, certified, and then deployed with the belief they would remain effective long-term. This logic is now obsolete. The war in Ukraine has revealed a different reality—one where electronic systems enter dynamic environments where adversaries constantly adapt and technological cycles shorten under operational pressure. In these conditions, the line between development and deployment blurs. As Jarosław Filimonow, CEO of Ukrainian C-UAS manufacturer Kvertus, told Evertiq, design is no longer about creating a final product to last for years but about maintaining a continuous update cycle. This shift undermines a core engineering assumption: that a system can be finalized, verified, and deployed as a stable solution. Instead, systems are now expected to evolve throughout their lifecycle—not for optimization, but for survival
