Purposes of Multi-role Helicopter:
- The Multi-Role helicopter can carry out multiple missions including search and rescue (SAR), surveillance, patrolling, fire-fighting, medical evacuation (MEDEVAC), and observation missions.
- It can also be deployed for transportation of cargo and personnel.
- Helicopters are particularly well-suited for search and rescue (SAR) operations, as they can quickly and efficiently reach remote or hard-to-access areas.
- Helicopters are also used for medical evacuation (medevac) missions, providing rapid transport for critically injured or ill individuals.
- Helicopters provide a speedy and effective way to respond to fires, particularly in rugged terrain and hard-to-reach areas.
- Military aviation today is looking at the next generation of military helicopters and the strategy to modernize vertical-lift capability long term, with improved avionics, electronics, range, speed, propulsion, survivability, and high-altitude performance.

Advantages of Using Multi-Role Helicopters:
- Multi-role helicopters will rescue individuals in hard-to-reach places like mountains or oceans. Faster mobilization than fixed-wing craft.
- Needs a smaller landing area and might land nearer to or at hospitals.
- Faster mobilization than fixed-wing craft.
- Safe & Survivable in the Most Rigorous Missions and Extreme Conditions
Multi-Role Helicopter in Maritime Applications:
With the ever-increasing capability of the helicopter and continuous improvement in the mission system-integrated sensor suite, the role has further expanded to anti-submarine warfare (ASW) and electronic warfare (EW).
A naval multi-role helicopter (MRH) has the flexibility of being employed for any role as required by the mission.
The MRH’s electro-optical/sonar suite thus becomes more complex as it provides navigation, situational awareness, target data, weapon guidance, and EW capability.
Popular MRH in Maritime:
Kamov:
The Russian Kamov Ka-27 helicopter was developed for the Russian Navy to carry out ASW and ferry troops. Like other Kamov military helicopters, it has a coaxial rotor, removing the need for a tail rotor.
It is in service in many countries including Russia, the Republic of China, and India. It also carries radar, magnetic anomaly detection system, or dipping sonar.
Kamov Ka-28 helicopter is designed to search, detect, track, and engage surfaced and submerged submarines. The later version Ka-28 is capable of undertaking long-endurance ASW missions with no reference waypoints, in all-weather conditions, at a range of over 200 km, and a sea state of up to five.
Sikorsky:
Sea Hawk series is a multi-mission US Navy helicopter based on the US Army UH-60 Black Hawk and a member of the Sikorsky S-70 family. The US Navy uses the H-60 airframe under the model designations SH-60B, SH-60F, HH-60H, MH-60R, and MH-60S which can be deployed aboard any air-capable ship.
The Seahawk can be employed for anti-submarine warfare, anti-surface warfare, naval special warfare insertion, search and rescue, combat search and rescue (CSAR), vertical replenishment, and medical evacuation. All Navy H-60s carry a rescue hoist for SAR/CSAR missions.
For countermeasures, it is fitted with Lockheed Martin’s AN/ALQ-210 electronic support measures system. Electronic warfare systems include the ATK AN/ AAR-47 missile warner, laser warning system, BAE Systems’ AN/ALQ-144 infrared jammer; BAE Systems’ AN/ALE-39 chaff and flare decoy dispenser.
Eurpoean NH-90:
NH Industries’ design makes extensive use of composite materials instead of riveted metal alloy plates, which makes the NH90 helicopter lighter and reduces routine maintenance and corrosion issues. Electronic fly-by-wire systems also contribute to the lift capacity, by saving the weight of heavy power-boosted hydraulic control systems.
The NH90 NFH naval variant can be used as either utility helicopters or in the ASW role. ASW helicopters add naval radar, dipping sonar and sonobuoys, and up to two missiles or torpedoes on side pylons.
Utility and Attack Helicopters:
Equipped with weapons systems for combat roles. While primarily attack helicopters, they can also perform transport and utility missions.
Versatile helicopters capable of performing various tasks, including transport, SAR, and medical evacuation.
Versatile helicopters capable of carrying troops, cargo, and weapons. Commonly used for transportation, search and rescue (SAR), and medical evacuation.
Examples: Sikorsky UH-60 Black Hawk, Eurocopter EC135, AH-64 Apache, Mil Mi-24 Hind, Mil Mi-8/17
Future Developments & Advancements in Muti-Role Helicopters:
The advances in Multi-Role helicopter designs have not been as impressive as for fighter aircraft. While jet fighters are in their fifth generation, the helicopters are still strutting around with the same old designs and airframes.
Today the global helicopter industry is undergoing a significant transformation as our customer demands and the capabilities offered by cutting-edge technologies.
Advances in technology such as computation structural dynamics modeling, expanded use of additive manufacturing, fly-by-wire controls, advanced condition-based maintenance (CBM), health and usage monitoring systems (HUMS), and advanced turbine engine programs, promise a big leap in rotorcraft capabilities.
The new generation Multi-Role helicopter platforms are expected to feature the latest advances in aeronautics giving military helicopters improved flight performance, especially in relation to speed.
Advances in stealth, such as reductions in radar and acoustic signatures offer major results in this area, as does the development of early detection/jamming countermeasure capabilities.
The US military has embarked on the most transformative science and technology initiative in decades – the joint multi-role (JMR) technology demonstration effort, where the industry plans to prove the revolutionary capabilities of high-speed approaches for a family of future military products.
Conclusion
Multirole helicopters are indispensable assets in modern aviation, offering unparalleled versatility and efficiency. Their ability to perform diverse tasks makes them critical for military, law enforcement, medical, search and rescue, and commercial operations, ensuring operational success and mission accomplishment in various challenging environments.
