This guide details the assembly of the 25mm M919 Armor-Piercing Fin-Stabilized Discarding Sabot with Tracer (APFSDS-T) round, as demonstrated by a subject matter expert. The process involves attaching the fin assembly to the penetrator, fitting sabot petals, securing an obturator for a gas seal, and finally inserting the projectile into the cartridge case. The demonstration highlights precise assembly techniques for complex sub-components, emphasizing the importance of correct military nomenclature and safe handling practices.

Quick Summary

The 25mm M919 APFSDS-T round assembly involves attaching the fin assembly to the penetrator, fitting three sabot petals for bore diameter, and snapping an obturator ring for a gas seal. The completed projectile is then inserted into the 25mm cartridge case. This process ensures optimal performance for anti-armor engagements from the M2 Bradley IFV.

Frequently Asked Questions

How is the M919 APFSDS-T round assembled?

Assembly begins by screwing the fin assembly onto the penetrator, followed by fitting three sabot petals around the penetrator's grooved section. A white obturator ring is then snapped over the sabot petals to ensure a gas-tight seal before the projectile is inserted into the 25mm cartridge case.

What are the key components of the M919 APFSDS-T round?

The M919 round features a high-aspect-ratio long-rod penetrator, typically made of Depleted Uranium, which is stabilized by fins. It uses a discarding sabot system with petals and an obturator ring for a gas seal, all housed within a 25mm cartridge case.

What is the primary use of the 25mm M919 APFSDS-T round?

The 25mm M919 APFSDS-T round is primarily used for anti-armor engagements and is fired from the 25mm M242 Bushmaster Chain Gun mounted on the M2 Bradley Infantry Fighting Vehicle (IFV).

What is the function of the sabot in an APFSDS round?

The sabot is a sleeve that surrounds the projectile, allowing a smaller caliber penetrator to be fired from a larger caliber gun. It provides a seal against the gun barrel's rifling and separates from the penetrator once it exits the muzzle.
