Which Rocket Launcher Can Destroy a Tank?

The simple answer is that many rocket launchers can destroy a tank, depending on factors like the age and type of the tank, the type of rocket launcher, the ammunition used, and the angle and location of impact. However, not all rocket launchers are equally effective, and even the most powerful ones are not guaranteed to penetrate the armor of every modern main battle tank (MBT).

The Destructive Power of Rocket Launchers

Rocket launchers designed to defeat armored vehicles, often referred to as anti-tank rocket launchers or recoilless rifles, rely on various mechanisms to penetrate and disable tanks. The most common are:

High-Explosive Anti-Tank (HEAT) warheads: These use a shaped charge to create a focused, high-velocity jet of molten metal that penetrates armor. The effectiveness of a HEAT warhead is measured by its armor penetration capability, expressed in millimeters of rolled homogeneous armor (RHA) equivalent.
High-Explosive Squash Head (HESH) warheads: These warheads spread a plastic explosive across the target surface. Upon detonation, the explosive creates a shockwave that travels through the armor, causing spalling (fragments of metal breaking off the interior surface), which can injure or kill the crew and damage internal systems.
Tandem-HEAT warheads: Used to defeat tanks equipped with explosive reactive armor (ERA), which detonates a small explosive charge to disrupt the incoming HEAT jet. Tandem-HEAT warheads consist of a smaller precursor charge to trigger the ERA and a larger main charge to penetrate the underlying armor.
Top Attack: Some modern systems are designed to attack the tank from above, where the armor is generally thinner and less protected. These often incorporate sophisticated guidance systems to achieve the optimal impact angle.

Key Rocket Launcher Systems and Their Capabilities

Several rocket launcher systems have proven their capability to damage or destroy tanks in combat. Some notable examples include:

RPG-7 (Soviet/Russian): The RPG-7 is one of the most widely used anti-tank weapons in the world. Its success stems from its simplicity, low cost, and adaptability. While older RPG-7 rounds may struggle against modern MBTs, newer rounds like the PG-7VR tandem-HEAT rocket are capable of defeating ERA and penetrating significant armor.
M72 LAW (USA): A lightweight, disposable, single-shot rocket launcher. While initially effective against older tanks, its limited penetration power makes it less effective against modern MBTs, primarily used against light armored vehicles and fortifications.
AT4 (Sweden/USA): A more powerful, disposable, single-shot weapon than the M72 LAW. While still relatively lightweight, it offers improved penetration capabilities and can be effective against older or less heavily armored tanks, or against the flanks and rear of modern tanks.
FGM-148 Javelin (USA): A sophisticated, fire-and-forget anti-tank missile system. The Javelin uses infrared guidance and a top-attack profile to target the vulnerable upper surfaces of tanks, making it highly effective against even modern MBTs.
NLAW (Next Generation Light Anti-tank Weapon) (Sweden/UK): Designed for infantry use, NLAW is a fire-and-forget system employing a predicted line-of-sight (PLOS) guidance system. It can be used in both overfly top attack (OTA) mode, or direct attack (DA) mode.
Spike (Israel): A family of advanced multi-purpose missiles with various ranges and capabilities. Spike missiles can be used against tanks, bunkers, and other targets. They use electro-optical and infrared guidance systems and can be fired in fire-and-forget or fire-and-observe modes, allowing for mid-course corrections and target re-engagement.
Panzerfaust 3 (Germany): A modern recoilless rifle system, the Panzerfaust 3 offers a significant improvement in penetration power compared to older systems like the RPG-7. Its tandem-HEAT warhead is designed to defeat ERA and penetrate modern tank armor.

Factors Affecting Effectiveness

The effectiveness of a rocket launcher against a tank is not solely determined by the weapon system itself. Several other factors play a crucial role:

Tank Armor: Modern MBTs are equipped with sophisticated composite armor, ERA, and active protection systems (APS) designed to defeat or mitigate the effects of anti-tank weapons.
Ammunition Type: The specific type of warhead used by the rocket launcher significantly affects its penetration capability. Newer warheads are designed to overcome modern armor technologies.
Impact Angle: A perpendicular impact provides the optimal penetration. Oblique impacts can significantly reduce the effectiveness of the warhead.
Range: Accuracy and penetration power can decrease with range.
Environmental Conditions: Visibility, weather, and terrain can all affect the accuracy and effectiveness of rocket launchers.
Training and Skill: A well-trained operator will be more likely to achieve a successful hit on a vulnerable spot of the tank.
Countermeasures: Tanks can deploy smoke screens, jamming devices, and other countermeasures to disrupt the guidance systems of rocket launchers.

Conclusion

While many rocket launchers possess the potential to destroy tanks, the success of any engagement depends on a complex interplay of factors. Modern MBTs are increasingly well-protected, necessitating the use of advanced rocket launcher systems with sophisticated warheads and guidance systems. The ongoing arms race between tank armor and anti-tank weaponry continues to drive innovation and development in both areas. The effectiveness of any particular rocket launcher ultimately depends on the specific context of the battlefield and the capabilities of both the attacker and the defender.

Frequently Asked Questions (FAQs)

1. Can a single RPG-7 destroy a modern main battle tank (MBT)?

While older RPG-7 rounds may struggle against modern MBTs, newer rounds like the PG-7VR tandem-HEAT rocket are specifically designed to defeat ERA and penetrate significant armor. Success is not guaranteed and depends heavily on the impact location and other factors.

2. What is ERA, and how does it protect tanks?

ERA (Explosive Reactive Armor) consists of small explosive charges sandwiched between metal plates. When a HEAT warhead strikes the ERA, the explosive charge detonates, disrupting the jet of molten metal and reducing its penetration capability.

3. What is an active protection system (APS)?

APS (Active Protection System) is a more advanced defense system that uses sensors to detect incoming projectiles and deploy countermeasures to intercept and destroy them before they reach the tank.

4. How effective is the M72 LAW against modern tanks?

The M72 LAW is generally considered ineffective against modern MBTs due to its limited penetration power. It is more suitable for use against light armored vehicles and fortifications.

5. What makes the FGM-148 Javelin so effective?

The Javelin’s top-attack profile and advanced infrared guidance system allow it to target the more vulnerable upper surfaces of tanks, making it highly effective against even modern MBTs.

6. What is the difference between HEAT and HESH warheads?

HEAT (High-Explosive Anti-Tank) warheads use a shaped charge to create a focused jet of molten metal to penetrate armor, while HESH (High-Explosive Squash Head) warheads create a shockwave that causes spalling inside the tank.

7. What is a tandem-HEAT warhead, and why is it necessary?

A tandem-HEAT warhead has two shaped charges: a smaller precursor charge to detonate ERA and a larger main charge to penetrate the underlying armor. It is necessary to defeat tanks equipped with ERA.

8. What is “spalling,” and why is it dangerous to tank crews?

Spalling refers to fragments of metal breaking off the interior surface of a tank’s armor after it is struck by a weapon. These fragments can travel at high velocity, injuring or killing the crew and damaging internal systems.

9. Can a tank be destroyed by hitting its tracks or wheels with a rocket launcher?

While hitting the tracks or wheels can immobilize a tank, it is unlikely to destroy it outright. The crew can still operate the tank’s weapons and potentially repair the damage.

10. Are there any rocket launchers that can penetrate the front armor of a modern MBT with 100% certainty?

No rocket launcher can guarantee 100% penetration of the front armor of every modern MBT under all circumstances. The effectiveness depends on many factors, including the specific type of armor, the ammunition used, and the angle of impact.

11. What is the range of most anti-tank rocket launchers?

Ranges vary widely, from a few hundred meters for short-range systems like the RPG-7 and M72 LAW to several kilometers for longer-range missile systems like the Javelin and Spike.

12. What is the primary advantage of a fire-and-forget system like the Javelin?

Fire-and-forget systems allow the operator to immediately move to a safer location after launching the missile, reducing their exposure to enemy fire.

13. How do environmental conditions affect the effectiveness of rocket launchers?

Poor visibility (e.g., fog, smoke) can hinder target acquisition and reduce accuracy. Wind can affect the trajectory of unguided rockets. Extreme temperatures can affect the performance of rocket motors and guidance systems.

14. Are there any defensive measures infantry can take against tanks besides using rocket launchers?

Yes, infantry can use anti-tank mines, improvised explosive devices (IEDs), and Molotov cocktails. They can also employ tactics such as ambushes and flanking maneuvers to exploit the tank’s weaknesses.

15. How is the future of anti-tank warfare evolving?

The future of anti-tank warfare is likely to involve increasingly sophisticated weapons and countermeasures, including advanced guidance systems, more effective armor technologies, active protection systems, and autonomous systems capable of detecting and engaging armored vehicles. Miniaturization, drones, and AI will play a large role in future anti-tank solutions.
