The TL-4 (Thunderbolt-4, 雷霆-4) is a Chinese air-to-surface missile (ASM) that is often mischaracterized. It is specifically designed as a anti-ship missile (AShM) and anti-armor missile, intended to be launched from helicopters and potentially slow-moving fixed-wing aircraft.
Key Features and Capabilities
Dual-Mode Seeker (SAL + IIR):
The TL-4 features a dual-mode guidance system combining Semi-Active Laser (SAL) and Imaging Infrared (IIR) seekers.
- Advantages:
- All-Weather, Day/Night Operation: IIR enables passive engagement in darkness or adverse weather.
- High Precision: SAL guidance ensures pinpoint accuracy against moving or static targets.
- Resistance to Countermeasures: IIR seeker distinguishes targets from decoys, while SAL allows for precise targeting in complex environments.
Fire-and-Forget & Fire-and-Update Capability:
Operators can lock and launch (fire-and-forget) using IIR, or guide the missile in real-time via laser designation (fire-and-update), offering tactical flexibility.
Top-Attack and Direct-Attack Modes:
Configurable flight profiles allow:
- Top-attack mode: Engages the weaker top armor of tanks.
- Direct-attack mode: Used against bunkers, buildings, or low-profile targets.
Soft Launch Technology:
The missile is ejected from the launch tube before motor ignition, minimizing backblast and enabling firing from confined spaces (e.g., urban structures, trenches).
Tandem HEAT Warhead:
Equipped with a tandem high-explosive anti-tank (HEAT) warhead to defeat explosive reactive armor (ERA) and penetrate advanced composite armor.
Extended Engagement Range:
With a range of up to 6 km, the TL-4 allows infantry to engage enemy armor beyond the effective range of most direct-fire weapons.

Strategic Role and Purpose
The TL-4 is designed for modern asymmetric and conventional warfare:
- Infantry Anti-Armor Defense: Enables small units to counter main battle tanks and armored columns.
- Urban Combat: Soft launch and compact design make it ideal for urban warfare.
- Special Operations: Lightweight and versatile for use by special forces in remote or high-risk environments.
- Force Multiplier: Extends the lethal reach of infantry, reducing reliance on heavier support systems.
Comparison to Other Systems
| System | TL-4 Advantage |
|---|---|
| U.S. FGM-148 Javelin | TL-4 offers dual-mode (SAL/IIR) guidance vs. Javelin’s IIR-only; potentially lower cost and export availability. Comparable range and top-attack capability. |
| Israeli Spike-LR | TL-4 has similar range and dual-mode seeker, but integrates SAL for higher precision in laser-designated scenarios. |
| Russian Kornet-EM | TL-4 is lighter and more portable; features fire-and-forget IIR mode, whereas Kornet requires continuous guidance (laser beam riding). |
| Chinese HJ-12 | TL-4 extends range (6 km vs. 4 km) and adds SAL guidance, offering greater flexibility in complex battlefield environments. |
Conclusion
The TL-4 represents a significant leap in China’s portable anti-armor technology. Its dual-mode seeker, soft launch capability, and 6 km range make it a highly versatile and lethal system for modern infantry. With performance comparable to the Javelin and Spike-LR, but with unique SAL guidance advantages, the TL-4 is poised to become a key export and frontline weapon in China’s ground arsenal.
