‘Stealth’ is the buzzword when we are talking about any modern fighter, bomber, warship or submarine. The top militaries in the word are spending billions trying to develop or ‘acquire’ stealth technology. But as is the case with science, the word ‘stealth’ is misunderstood by the general public. It is viewed as a phenomenon which is like magic and makes things invisible and invincible. In this article, I will explain the physics and engineering principles behind stealth technology and will try my best to give you a clear understanding of how this complex technology works.
