What makes a fifth generation fighter aircraft distinctly different from earlier generations in terms of stealth technology?

Fifth generation fighter aircraft feature revolutionary stealth capabilities through innovative shaping design and internal weapon bays. Unlike conventional fourth-generation aircraft with external weapons, the AMCA can carry up to one and a half tons of payload internally to maintain stealth characteristics. Additionally, India has indigenously developed radar-absorbing materials that are embedded into the composite structure rather than applied as paint. This monolithic structure approach eliminates maintenance issues of paint peeling off, reducing overall maintenance requirements while effectively reducing radar cross-section signature.
