Ka-52K "Katran"
The Kamov Ka-52K "Katran" is the navalized version of Russia's Ka-52 "Alligator" attack helicopter. Developed by the Kamov Design Bureau under Russian Helicopters, the Ka-52K was specifically designed for shipborne operations, featuring folding rotor blades and wings, a corrosion-resistant marinized structure, and advanced combat systems. Compared with the land-based Ka-52, the Katran is heavier but optimized for maritime warfare, amphibious assault support, convoy escort, and operations from amphibious assault ships.
Background & Development
- Country of Origin: Russia
- Manufacturer: Kamov Design Bureau / Russian Helicopters
- Role: Shipborne attack and reconnaissance helicopter
- Program Origin: Developed for the French-built Mistral-class amphibious assault ships
- Service Introduction: Mid-2010s
- Nickname: "Katran" (Russian for "mud shark")
Following the cancellation of Russia's acquisition of the Mistral-class ships, the Ka-52K program continued and is expected to support future Russian amphibious assault vessels, including the Project 23900 class.

Design Features
Coaxial Rotor System
The Ka-52K employs Kamov's signature counter-rotating coaxial rotor configuration, eliminating the need for a tail rotor and providing excellent agility and survivability.
Marinized Construction
Corrosion-resistant materials and protective coatings allow prolonged operation in harsh maritime environments.
Folding Blades and Wings
Both rotor blades and stub wings fold to reduce storage space aboard ships.
Advanced Avionics
- Arbalet radar
- Electro-optical targeting system
- Night vision capability
- Short-range radio-technical navigation system
- Digital flight-control systems
Ejection Seats
The Ka-52K features K-37-800 ejection seats, making it one of the few attack helicopters in the world equipped with a crew escape system.
Operators
Russia
Russia remains the primary operator of the Ka-52K, intended for use by Russian Naval Aviation.
Egypt
Egypt operates the standard Ka-52 Alligator but has not introduced the naval Ka-52K variant.
Comparison: Ka-52 vs Ka-52K Katran
| Feature | Ka-52 Alligator | Ka-52K Katran |
|---|---|---|
| Role | Land-based attack helicopter | Shipborne naval attack helicopter |
| Maximum Takeoff Weight | 10,800 kg | 12,200 kg |
| Payload | 2,500 kg | 2,000 kg |
| Rotor System | Fixed coaxial | Folding coaxial |
| Stub Wings | Fixed | Folding |
| Crew | 2 | 2 |
| Main Armament | Cannon, rockets, ATGMs, AAMs | Cannon, rockets, ATGMs |
| Special Feature | Advanced avionics and ejection seats | Marinized structure and naval operation capability |
Strengths
- Excellent maneuverability due to the coaxial rotor design.
- Compact folding structure for shipboard deployment.
- Powerful anti-armor weaponry.
- Rare ejection-seat system enhances crew survivability.
- Capable of operating in harsh maritime environments.
- Potential anti-ship strike capability.
Risks & Limitations
- Lower payload compared with the standard Ka-52.
- Primarily optimized for naval missions, reducing operational flexibility.
- Limited export success.
- Production numbers remain relatively small.
- Dependence on future Russian amphibious assault ships for full deployment potential.
Conclusion
The Ka-52K "Katran" represents Russia's effort to create a dedicated shipborne attack helicopter by combining the combat capabilities of the Ka-52 Alligator with specialized naval features. Although the cancellation of the Mistral-class program affected its original purpose, the Katran remains one of the most heavily armed naval attack helicopters in the world and is expected to play an important role in future Russian amphibious operations.
