Shifting To Unmanned For Maritime Missions
Maritime Domain Awareness (MDA) stands as a crucial pillar of national security, encompassing the comprehensive monitoring and understanding of activities within the maritime domain. This holistic approach is essential for ensuring the safety, security, and environmental protection of maritime operations. However, achieving effective MDA is a daunting task due to the vastness of the ocean, the sheer number of vessels at sea, and the limited resources available for law enforcement. Nefarious activities such as Illegal smuggling, illegal, unreported, and unregulated fishing (IUUF), and illegal immigration further complicate MDA efforts, necessitating innovative solutions to address these complex challenges.
For years, MDA heavily relied on manned airborne Intelligence, Surveillance, and Reconnaissance (ISR) aircraft to monitor maritime activities. However, these missions come with inherent limitations, including limited flight hours, stringent safety considerations, and mission predictability. Manned aircraft are also associated with high fuel consumption rates, leading to increased pollution, particularly in environmentally sensitive areas.
In recent years, there has been a notable shift towards utilizing unmanned systems for MDA, offering numerous advantages over manned aircraft. Unmanned systems are more efficient and less risky, as they eliminate the need for a pilot to fly manually at low altitudes. They also have significantly lower fuel consumption rates, resulting in reduced carbon emissions and pollution. The Heron Unmanned Aerial System (UAS) developed by Israel Aerospace Industries (IAI) consumes only 20 lbs of fuel per hour, compared to 1000 lbs per hour for a manned aircraft.
Apart from environmental benefits, unmanned systems offer superior data dissemination capabilities compared to manned aircraft. All data collected by unmanned systems is transmitted in real-time to a Ground Control Stations (GCS), where it can be quickly analyzed and disseminated to relevant authorities. This real-time data transmission capability is critical for ensuring timely decision-making and response to potential threats in the maritime domain.
Furthermore, unmanned systems are more cost-effective than manned aircraft, offering significant savings in operational costs. The lower operational costs of unmanned systems make them a more sustainable and efficient option for long-duration maritime surveillance missions.
Israel recognized the advantages of unmanned systems and has shifted from manned aircraft to unmanned aerial systems for MDA. The Heron UAS, being the main airborne maritime ISR asset used by Israel, has played a pivotal role for the past ten years, and continues to support these missions. Its ability to operate in harsh weather conditions as well as land, refuel, and take off from remote airfields with minimal logistical support, makes it a versatile and effective tool for MDA.
The integration of AI technology into unmanned systems has further enhanced their capabilities for MDA. IAI's integration of Windward software into the Heron UAS represents a significant advancement in this regard. Windward software assesses risk levels using open-source data and a ship's historical data. Ships are classified into red (high risk), yellow (low risk), and green (no risk) categories. These classifications are based on historical data, including deviations from normal economic routes, past illegal activity, instances of turning off their transponder, and other relevant factors providing valuable insights for maritime surveillance operations.
The integration of Windward software into the Heron UAS enables a real-time fusion of data from the UAS's sensors with Windward's constant monitoring. This integration allows the Heron UAS to effectively identify and track vessels of interest, enhancing its surveillance capabilities. The Heron UAS also utilizes cross-cueing between real-time sensor data and Windward's risk assessments, further enhancing its situational awareness and target identification capabilities.
The U.S. Navy has also recognized the value of unmanned systems for MDA, as evidenced by its "hybrid fleet" approach. The 4th Fleet unmanned campaign showcases the Navy's efforts to evaluate and incorporate various unmanned systems into its operations. This approach highlights the Navy's commitment to leveraging unmanned systems to enhance its maritime surveillance capabilities and address emerging threats in the maritime domain.
Unmanned systems offer significant advantages over manned aircraft for MDA, including increased efficiency, lower risk, and lower environmental impact. As technology continues to advance, unmanned systems will play an increasingly important role in ensuring maritime security and protecting the marine environment.
