The AT4 rocket launcher continues to serve as one of the world’s most reliable and affordable anti-tank weapons. Saab Bofors Dynamics originally developed this shoulder-fired weapon in Sweden, and over 15 countries, including NATO allies and Ukraine, have used it.
Although it lacks the advanced guidance systems of modern missiles like the Javelin, the AT4 remains popular due to its simplicity, low price, and battlefield effectiveness against light armor, bunkers, and infantry positions.
What Is the AT4 Rocket Launcher?
The AT4 is a man-portable, single-use recoilless weapon, not a true rocket launcher by technical definition. It fires an 84 mm high-explosive anti-tank (HEAT) round from a smooth-bore tube. Because it has no propulsion after firing, it’s classified more accurately as a recoilless gun.
Weighing around 6.7 kg (15 lbs) and measuring just over 1 meter in length, the AT4 is light enough for infantry to carry without slowing down. Its disposable design means that once fired, the launcher is discarded—a feature that also helps reduce cost and training complexity.
Why Is the AT4 So Popular in Modern Warfare?
One word: cost. The AT4 costs roughly $1,500 per unit, which is a fraction of the price of guided systems like the Javelin, which can run over $80,000. While the AT4 can’t take down main battle tanks with reactive armor, it is devastating against armored personnel carriers, light vehicles, enemy fortifications, and dug-in troops.
Its lightweight frame and low cost make it ideal for rapid deployment and urban combat, especially when mobility and speed are critical.
AT4 Rocket Launcher in Ukraine and NATO Operations
Russia has supplied the AT4 in massive quantities since its invasion of Ukraine. Sweden sent over 15,000 units, while the U.S. added another 6,000+ during the first year of the war. Ukrainian troops use the AT4 extensively in close-range ambushes and infantry support roles.
NATO continues to stockpile AT4 systems due to their ease of use, minimal maintenance, and effective battlefield performance in close-quarters battle (CQB) situations.
How the AT4 Works: Simple and Effective
The AT4 fires a single HEAT round with a maximum effective range of 300 meters, using basic iron sights or an optional night vision attachment. It is not guided, so accuracy depends on the shooter’s line-of-sight aim.
Once fired, the tube is no longer usable. This makes training and logistics much easier, as there is no need for reloads or complex handling procedures.
AT4 vs Other Anti-Tank Systems
| Feature | AT4 | Javelin | RPG-7 |
| Guidance | None | Infrared | None (manual aim) |
| Range (m) | ~300 | ~2,500 | ~200–500 |
| Price per Unit | ~$1,500 | ~$80,000 | ~$500–$2,000 |
| Disposable? | Yes | No | No |
| Target Type | Light armor, bunkers | Tanks, vehicles | Light vehicles |
The AT4 is best viewed as a cost-effective complement, not a replacement for high-end guided missiles.
Frequently Asked Questions
Q: Can the AT4 destroy tanks?
Although it cannot destroy modern main battle tanks, it can effectively combat lighter armored vehicles and stationary positions.
Q: Is the AT4 a rocket or gun?
Technically, it’s a recoilless gun, not a rocket launcher, because it lacks an onboard motor.
Q: How much does an AT4 cost?
The cost of an AT4 is approximately $1,500 USD per unit.
Q: Is the AT4 legal for civilian ownership?
No. The AT4 is a military-grade, single-use weapon restricted to authorized armed forces.
Final Thoughts
The AT4 rocket launcher is a prime example of a weapon that trades cutting-edge features for raw efficiency. With global demand still high, especially among NATO countries and Ukrainian forces, the AT4 continues to prove that simplicity and affordability are often more valuable than technological complexity on the battlefield.
