150 mm Precision Sabotage Round — Passive Infrared Homing & Dual-Charge Warhead
The IR-150 is a next-generation precision munition designed for targeted sabotage and high-value destruction. Measuring 150 mm in length, the bullet features a drilled tip that houses a passive electronic circuit, an infrared LED, two electrodes connected to a dual explosive charge, and two internal shifting weights that actively alter the projectile's trajectory mid-flight. Upon impact, the dual charge detonates with devastating force, guaranteeing mission success against hardened or thermally distinct targets.
Its innovative weight-shift guidance system enables real-time course correction, while the passive thermistor-based arming mechanism ensures the round only activates under specific environmental conditions — reducing the risk of premature detonation and enhancing operational safety.

ALLOY Body Material
Aluminium 7075 — High specific strength, fatigue-resistant aerospace-grade alloy.
Carbon Fibre Reinforcement — Added rigidity and corrosion resistance for extreme environments.
EXPLOSIVE Warhead Fill
TNT (Trinitrotoluene) — C₇H₅N₃O₆
Total mass: 500 g (two independently initiated 250 g charges).
CIRCUIT Passive Electronic Core
Thermistor: NTC type, activation threshold ≤ 0 °C | Comparator: LM393-based, ultralow current draw | Mechanical Switch: Spring-loaded, closes on impact | Power Source: Single-use lithium-polymer battery, high energy density.
Bidirectional weight displacement alters the centre of gravity for real-time trajectory correction.
1. Passive Arming
Thermistor detects ambient temperature ≤ 0 °C. Comparator verifies the threshold and arms the detonation chain only under the correct environmental signature.
2. IR Illumination
940 nm LED activates at launch, providing a thermal-contrast beacon for IFF tracking or active seeker handoff.
3. Impact Detonation
Mechanical switch closes on impact, sending a firing signal to both electrodes. Dual 250 g charges detonate simultaneously at ~3,000 °C.
The IR-150 is purpose-built for covert sabotage, precision infrastructure denial, and anti-materiel operations. Its thermal arming logic, passive IR illumination, and weight-shift steering make it ideal for:
