### Overview

Duretek, a South Korean defense startup led by CEO Kim Hyeong-se, has developed a new generation of ammunition that challenges long-held assumptions about bullet design. Traditionally, it was believed that bullets had to be heavy and fired from long barrels to achieve long-range accuracy and penetration. Duretek’s approach, however, focuses on optimizing the bullet’s aerodynamics and weight distribution, resulting in a lighter, faster, and more accurate projectile. citeturn0search0

### Key Innovations

#### 1. Aerodynamic Enhancements
- **Air-Guiding Grooves:** 
  Duretek’s bullets incorporate specially engineered grooves (often referred to as "air guidance grooves") along the projectile’s surface. These grooves reduce the turbulence and drag experienced during flight. This design minimizes the wobbling (or precession) that typically degrades accuracy, leading to a more stable trajectory.
 
- **Forward Center of Gravity:** 
  By shifting the weight distribution toward the front of the bullet, the projectile maintains a more consistent flight path, thereby increasing both accuracy and effective range. citeturn0search7

#### 2. Increased Performance Metrics
- **Extended Effective Range:** 
  For example, a 5.6 mm bullet developed under this technology has seen its effective range increased from 460 m to over 600 m—a boost of more than 40%. This enhanced range is achieved without simply adding more propellant, but by refining the bullet’s design to reduce drag and improve flight stability. citeturn0search7

- **Enhanced Penetration Capability:** 
  Tests have demonstrated that bullets using this technology can penetrate thicker and more robust materials. One variant of a 5.56 mm bullet reportedly penetrated 6.5 mm of bulletproof steel at 100 m, while a 7.62 mm version was able to pierce a 3.5 mm steel plate at a distance of 1 km. Such performance upgrades suggest significant improvements in both range and destructive power. citeturn0search0

#### 3. Versatility Across Environments

- **Amphibious (Underwater) Capability:** 
  One of the most groundbreaking features is the development of an underwater bullet. Traditional ammunition struggles in water because of the high density and resistance water presents. Duretek’s underwater bullet features a uniquely shaped tip that, upon impact with water, vaporizes a thin layer of it. This creates a transient air cavity (or tunnel) around the projectile, allowing it to travel underwater with reduced resistance. This innovation makes it possible to conduct effective operations in both terrestrial and aquatic environments without changing ammunition types. citeturn0search0

- **Applicability to Various Calibers:** 
  Although initially applied to small-caliber (such as 5.6 mm and 5.56 mm) rounds, the underlying technology is versatile enough to be adapted for larger calibers—potentially benefiting systems ranging from small arms to larger autocannons (e.g., 20 mm, 30 mm rounds). This means existing weapon platforms can benefit from performance improvements without requiring modifications to the firearms themselves. citeturn0search7

### Technological Impact and Future Prospects

- **Game-Changing Potential:** 
  With extended range, increased accuracy, and improved penetration power, these bullets are poised to be a “game changer” on the battlefield. The ability to engage targets at longer distances and under challenging conditions (like underwater scenarios) can shift the dynamics of modern warfare.
 
- **Patents and Research:** 
  The technology is backed by a robust portfolio of patents—over 37 in total—which cover various aspects of the ammunition design, including the aerodynamic improvements and the innovative underwater capability. This extensive research and intellectual property portfolio underline the potential impact of these advancements on future military operations. citeturn0search0

- **Operational Flexibility:** 
  By enabling the use of a single type of ammunition in both ground and water operations, Duretek’s technology simplifies logistics and potentially reduces costs, while offering tactical advantages such as longer engagement ranges and more effective target penetration.

### Conclusion

Duretek’s innovative bullet design represents a significant leap forward in ammunition technology. By rethinking the traditional design constraints—prioritizing aerodynamic efficiency, improved weight distribution, and versatility—Duretek has developed projectiles that not only achieve greater range and accuracy but also excel in penetrating modern armor and even operating underwater. This breakthrough could reshape operational strategies in various combat scenarios, marking a notable advancement in modern military technology. citeturn0search0 citeturn0search7
