100 mm Fixed Ammunition with HEAT-T M15 Overview

The 100 mm HEAT-T M15 round is a High-Explosive Anti-Tank (HEAT) cartridge with Tracer (T), used in 100mm tank and anti-tank guns. It is designed to defeat armored vehicles, especially tanks, using a shaped charge warhead that focuses explosive energy to penetrate armor.

The round is fixed-type, meaning the projectile and cartridge case are a single unit, intended for rapid loading in combat conditions.

Key Features

• Caliber: 100 mm
• Ammunition Type: Fixed
• Projectile Type: HEAT (High-Explosive Anti-Tank)
• Designation: M15
• Tracer: Yes (visible during flight for tracking)
• Purpose: Anti-armor, especially main battle tanks and armored vehicles

Technical Data (Typical for HEAT-T M15)

• Round Weight: ~23–25 kg
• Projectile Weight: ~13–15 kg
• Muzzle Velocity: ~900 m/s
• Penetration Capability: ~400–450 mm RHA (Rolled Homogeneous Armor), regardless of distance
• Effective Range: ~1,500–2,000 meters
• Fuse Type: Point-detonating, with base or nose-mounted piezoelectric initiation
• Stabilization: Fins (not spin-stabilized, to preserve shaped charge effect)

Functionality – How HEAT Works

• HEAT warheads utilize a shaped charge liner (usually copper)
• On impact, an explosive forms a high-velocity metal jet that penetrates armor
• Unlike kinetic rounds, penetration is not velocity-dependent, meaning it retains full effectiveness at longer ranges

Typical Platforms

• T-54/T-55 tanks (using the D-10T gun)
• SU-100 tank destroyer
• BS-3 100 mm anti-tank gun
• Self-propelled artillery with 100 mm gun systems
• Some coastal defense and static artillery guns

Use Cases

• Engagement of heavily armored vehicles such as tanks and IFVs
• Urban combat — destroying fortified positions or armor behind cover
• Ambush scenarios — effective even at medium range

Advantages

• High armor penetration even at long range
• Lightweight compared to kinetic AP rounds
• Does not rely on high velocity, making it effective at stand-off ranges
• Tracer helps gunner adjust aim quickly

Limitations

• Not effective against reactive armor or modern composite armor without tandem charge
• Sensitive to angle of impact – oblique hits reduce penetration
• Less useful against soft targets or infantry
