SIXT.VN is here to dive deep into this fascinating topic, exploring the science behind it and revealing the capabilities of specialized ammunition designed for underwater use in Vietnam. We’ll uncover the secrets of supercavitation and how it enables projectiles to travel further and more accurately through water, all while highlighting the exciting travel destinations Vietnam has to offer. Learn about underwater shooting, aquatic ballistics, and Vietnamese tourism.
1. The Physics of Bullets and Water: What Happens When a Bullet Enters Water?
When a bullet enters water, its speed drastically reduces due to the significant difference in density between air and water. The water resistance, also known as drag, is much higher than air resistance.
1.1. Density Differences Explained
Water is approximately 800 times denser than air. This means that a bullet experiences far greater resistance when moving through water. According to research from the National Ocean Service in 2023, water density significantly impacts projectile motion (National Ocean Service, 2023).
1.2. Drag and Deceleration
As a bullet enters water, it creates a pressure wave in front of it. This wave, combined with the friction of the water against the bullet’s surface, causes rapid deceleration. Standard bullets can travel at half a mile per second in the air, but this speed quickly diminishes to a halt in water.
1.3. Stability Issues
The stability of the bullet is also compromised. In air, the bullet spins to maintain a stable trajectory. However, water’s high density can cause the bullet to tumble, further reducing its effective range and accuracy.

2. Can Regular Bullets Travel Through Water?
Regular bullets can travel through water, but their range and effectiveness are severely limited. Standard bullets not designed for aquatic environments will lose velocity and stability very quickly.
2.1. Limited Range of Standard Bullets
The range of a standard bullet in water is typically just a few feet. The high drag force and rapid deceleration prevent it from traveling any significant distance. A study by the U.S. Army Research Laboratory in 2022 confirmed the limited range of standard bullets underwater (U.S. Army Research Laboratory, 2022).
2.2. Instability and Tumbling
As a standard bullet enters water, it becomes unstable. The water resistance causes it to tumble, deviating from a straight path. This tumbling further reduces its range and accuracy, making it ineffective for any practical underwater shooting.
2.3. Energy Dissipation
The energy of the bullet is quickly dissipated as it moves through the water. The friction and pressure waves generated by the bullet’s movement consume its kinetic energy, causing it to slow down rapidly.
3. Supercavitation: The Technology That Allows Bullets to Travel Further Underwater
Supercavitation is a technology that creates a gas bubble around a bullet, allowing it to travel much further and faster through water. This reduces drag and maintains stability.
3.1. How Supercavitation Works
Supercavitating bullets are designed to create a gas bubble as they move through water. This bubble reduces the surface area in contact with the water, minimizing drag. The shape and rotation of the bullet help maintain this bubble, allowing for greater speed and range.
3.2. Design of Supercavitating Bullets
These bullets typically have a unique design with a pointed tip and a carefully balanced shape. The tip is designed to initiate the formation of the gas bubble, while the body of the bullet maintains its stability within the bubble. DSG Technologies is a leading manufacturer of supercavitating ammunition.
3.3. Advantages of Supercavitation
The primary advantage of supercavitation is the increased range and accuracy of bullets underwater. Supercavitating bullets can travel up to 60 meters underwater and penetrate steel from a significant distance, making them effective for specialized applications.

4. Types of Supercavitating Ammunition
Several types of supercavitating ammunition are available, each designed for specific purposes and weapons systems.
4.1. CAV-X Bullets
CAV-X bullets, manufactured by DSG Technologies, are among the most well-known supercavitating rounds. They are available in various calibers and are designed for use in both partial and fully submerged weapons. According to Defense One, .50 caliber CAV-X bullets can travel up to 60 meters underwater and penetrate 2 centimeters of steel from 17 meters away.
4.2. Applications of Different Calibers
Different calibers of supercavitating ammunition are used for various applications. Smaller calibers may be used for personal defense weapons, while larger calibers are suitable for anti-material purposes, such as penetrating underwater obstacles or damaging submerged equipment.
4.3. Compatibility with Firearms
Supercavitating bullets can be used in conventional firearms, but a gas-piston firearm is often required for optimal underwater shooting. DSG Technologies is currently testing its ammunition with firearms used by the U.S. military.
5. Military and Special Operations Use of Underwater Bullets
Underwater bullets are primarily used by military and special operations forces for specialized tasks. These include underwater combat, sabotage, and protection of naval assets.
5.1. Special Forces Applications
Special forces units may use underwater bullets for covert operations, such as neutralizing underwater threats or breaching submerged defenses. These bullets provide a tactical advantage in scenarios where standard firearms are ineffective.
5.2. Anti-Terrorism Measures
Underwater bullets can be used in anti-terrorism efforts to protect ports, ships, and other critical infrastructure from underwater attacks. They can also be used to neutralize underwater mines or other explosive devices.
5.3. Protection of Naval Assets
Naval forces can use underwater bullets to defend against underwater threats, such as divers or unmanned vehicles attempting to damage ships or submarines. The ability to engage targets underwater provides an additional layer of security.
6. Ethical and Legal Considerations
The use of underwater bullets raises several ethical and legal considerations. It is important to ensure that these weapons are used responsibly and in accordance with international laws and regulations.
6.1. Rules of Engagement
Military and law enforcement agencies must establish clear rules of engagement for the use of underwater bullets. These rules should specify when and how these weapons can be used, as well as the level of force that is authorized.
6.2. International Laws and Treaties
The use of underwater bullets must comply with international laws and treaties governing the use of force in armed conflict. These laws prohibit the use of weapons that cause unnecessary suffering or are indiscriminate in their effects.
6.3. Civilian Safety
It is essential to minimize the risk of harm to civilians when using underwater bullets. This requires careful planning and execution of operations, as well as thorough training for personnel who use these weapons.
