Guided artillery shells (munitions) - M982 Excalibur, 2K25 Krasnopol, Leonardo Vulcano

Guided artillery shells (or munitions) are modern artillery projectiles equipped with an internal guidance system to change their flight direction in mid-air to hit targets with a very high degree of accuracy. Unlike conventional artillery shells, which rely on calculated firing angles and are susceptible to misses due to wind or weather factors, these smart munitions can self-correct their trajectory after being fired from the cannon barrel.

Guidance System Types

Satellite System (GPS/INS): Uses global positioning coordinates to guide the projectile directly to a predetermined stationary target.

Laser Guidance (Semi-Active Laser): Requires a ground operator or drone to "spotlight" the target using a laser beam. The bullet's sensor then tracks the laser reflection, making it highly effective against moving targets.

Self-Sensing Guidance (Infrared/Radar): Equipped with a self-contained seeker to automatically detect the heat signature (infrared) or radar of enemy armored vehicles.

Examples of Popular Guided Artillery Rounds

Some of the most well-known guided artillery munitions used in modern combat include:

M982 Excalibur

M982 Excalibur (United States/Sweden)

Caliber: 155mm.

Guidance System: GPS and Inertial Guidance.

Advantages: Compatible with modern howitzer systems such as the M777 and CAESAR, it boasts extreme accuracy with a radius of error of less than 2 meters.

2K25 Krasnopol

2K25 Krasnopol (Russia)

Caliber: 152mm or 155mm.

Guidance System: Semi-automatic laser.

Advantages: Extremely lethal against moving vehicles such as tanks because the round travels directly to the target's laser beam.

Leonardo Vulcano

Leonardo Vulcano (Italy)

Caliber: 127mm (naval) and 155mm (land artillery).

Guidance System: GPS/INS combined with optional laser guidance.

Advantages: Uses a sub-caliber, sabot-loaded design, allowing it to achieve extremely long ranges (up to 70 km).

Key Advantages in Combat

Logistical Efficiency: Drastically reduces the number of rounds fired; one smart round is often sufficient to replace dozens of conventional rounds.

Reduced Collateral Damage: High accuracy ensures military targets are destroyed without excessive damage to surrounding civilian areas.

Surprise Effect: Capable of destroying high-value enemy targets (such as command posts or radars) with the first shot.
