Nanotechnology in the armed forces: stronger, lighter materials and the ethical debate it opens

TechnologyInternationalCiencia UNAMAI summary

Nanotechnology, which manipulates matter at the atomic and molecular scale (between 1 and 100 nanometers), is being integrated into defense equipment: helmets with carbon nanocomposites or ceramic nanoparticles, graphene-reinforced vests, semiconductors for night vision and radars, and steels with niobium or vanadium to resist corrosion at sea. The goal is more protection with less weight and greater energy efficiency. The text warns about its "dual use" and the need for legal reviews of new weapons.

In 40 seconds

  • Nanotechnology works at a scale of 1 to 100 nanometers and enables materials with mechanical, thermal and electrical properties different from conventional ones.
  • In defense it is used in helmets with carbon or ceramic nanocomposites, graphene vests, night vision and semiconductors such as gallium nitride and gallium arsenide.
  • In aircraft and ships it seeks to reduce weight and fuel consumption and increase corrosion resistance.
