Flechette

A flechette is a dart-like projectile, typically made of steel, often used as a projectile in specialized artillery shells, firearms ammunition, and air-dropped weapons. Flechettes are characterized by their aerodynamic shape, featuring a pointed tip and stabilizing fins at the rear, which allow them to maintain a stable trajectory and high velocity in flight.

Flechettes are often deployed in large numbers from a single munition, creating a saturation effect over a targeted area. This wide dispersal makes them effective against personnel in open areas, light vehicles, and soft targets. The individual flechettes, due to their high velocity and small size, can penetrate light armor and inflict significant damage.

Historically, flechettes have been used in various conflicts, including World War I (in early aircraft-dropped versions), the Vietnam War, and more recent conflicts. The use of flechettes has been controversial due to concerns about their potential for indiscriminate effects and the severity of the wounds they inflict.

The specific design and dimensions of flechettes can vary depending on the intended application and weapon system. Modern flechettes often incorporate advancements in materials science and manufacturing techniques to enhance their performance.
