Historically, construction machinery has evolved significantly since the inception of the industry. In the early 20th century, construction relied heavily on manual labor and simple machinery. The introduction of steam-powered shovels and cranes marked the beginning of mechanization in construction. By the mid-20th century, advancements in technology led to the development of powerful equipment such as bulldozers, excavators, and concrete mixers. These machines dramatically increased productivity, allowing contractors to complete projects faster and with greater precision.

One of the most groundbreaking developments in stealth chassis technology is the use of metamaterials—artificial materials designed to manipulate electromagnetic waves. These materials can alter the way radar signals interact with an object, effectively bending or redirecting waves around it. Incorporating metamaterials into a chassis can significantly reduce its RCS, making it extremely difficult for radar systems to detect. This innovation marks a significant leap forward from traditional stealth techniques, which often rely on shape and surface coating alone.
