This video details the assembly of the 25mm M919 APFSDS-T round for the M2 Bradley IFV. It covers the critical steps of attaching the fin assembly to the penetrator, fitting the sabot petals for a flight seal, and installing the obturator for a gas-tight seal. The final step shows the projectile being inserted into the 25mm cartridge case, highlighting the precision required for this advanced military ammunition.

Quick Summary

The 25mm M919 APFSDS-T round assembly begins with attaching the fin assembly to the long-rod penetrator. Three sabot petals are then fitted around the penetrator for a flight seal, followed by an obturator ring to ensure a gas-tight seal. Finally, the projectile is inserted into the 25mm cartridge case.

Frequently Asked Questions

What are the main components involved in assembling the 25mm M919 APFSDS-T round?

The assembly involves the long-rod penetrator, the fin assembly, three sabot petals, an obturator ring, and the 25mm cartridge case. Each part plays a critical role in the round's function and performance.

What is the purpose of the sabot petals in an APFSDS round?

Sabot petals surround the penetrator and provide a flight seal during firing. They ensure the projectile fits the gun's bore diameter and discard after leaving the barrel, allowing the fin-stabilized penetrator to fly true.

How is a gas-tight seal achieved during the M919 round assembly?

A white obturator ring is snapped into place over the sabot petals. This component creates a gas-tight seal within the cartridge case, preventing propellant gases from escaping and ensuring maximum energy transfer to the projectile.

What vehicle uses the 25mm M919 APFSDS-T ammunition?

The 25mm M919 APFSDS-T round is specifically designed for use with the M242 Bushmaster Chain Gun, which is the primary armament of the M2 Bradley Infantry Fighting Vehicle (IFV).
