APDR_Bulletin_728X90Australia is once again grappling with a severe bushfire that endangers both wildlife and human communities. In response, reports have been flooding into emergency services, and a cutting-edge quadcopter is now airborne to provide crucial aerial oversight from high altitude. The drone is equipped with a high-performance, long-range day and thermal optical payload essential for such missions. This advanced long-endurance drone plays a vital role in disaster management by offering continuous monitoring of the fire and delivering early warnings about its spread. Additionally, it supports police and first responders in managing and supervising the affected areas, enhances search and rescue operations, and aids firefighters in their efforts to combat the blaze.

Israel Aerospace Industries (IAI), Israel’s leading defence supplier, has unveiled a groundbreaking addition to its unmanned aerial systems portfolio—the APUS 25. This innovative long-endurance quadcopter is set to redefine tactical drone operations for first responders, paramilitary, and military forces worldwide. The APUS 25 represents a significant leap forward in drone technology, offering an unprecedented combination of vertical takeoff and landing (VTOL) capabilities with extended flight times typically associated with fixed-wing aircraft. This unique blend of features addresses several critical pain points faced by users in the field.

APUS 25 3At the heart of the APUS 25’s innovation is its propulsion system. Unlike conventional electric quadcopters that rely on multiple electric motors, the APUS 25 utilizes a single, centrally located internal combustion engine. This engine operates at a fixed RPM, powering four rotors through a patented variable-pitch mechanism. The result is a dramatic increase in flight endurance—up to 8 hours—compared to the mere tens of minutes offered by electric counterparts. The use of a heavy-fuel engine brings additional advantages. The APUS 25 can operate on various fuel types, including Jet-A1, JP5, and JP8, eliminating the logistical challenges associated with battery-powered drones, such as long charging times and the need for specialized storage facilities.

In terms of payload capacity, the APUS 25 punches well above its weight class. With a maximum takeoff weight of under 25 kg, it can carry payloads of up to 10 kg for extended missions. This opens up a wide range of possibilities for emergency response, ISR (Intelligence, Surveillance, and Reconnaissance) operations, as well as potential combat support roles. The drone’s advanced design allows it to operate effectively in challenging environments, withstanding wind speeds of up to 23 knots and reaching altitudes of 11,000 feet. The APUS 25’s exceptional manoeuvrability is notable, allowing it to execute tight turns and swift altitude adjustments—capabilities vital for handling gusty winds and operating from ship decks.

One of the most significant advantages of the APUS 25 is its ability to hover for extended periods. Its liquid-cooled engine allows for prolonged stationary flight without the need for airflow cooling, a limitation often faced by fixed-wing VTOL drones. This makes the APUS 25 ideal for persistent surveillance missions or providing overwatch for first responders. Despite its small size, the drone boasts impressive capabilities, and its compact footprint allows for easy transport and deployment from a variety of platforms. This organic asset can be rapidly deployed by frontline units, providing immediate aerial support without the need for extensive launch infrastructure.

IAI has designed the APUS 25 with versatility in mind. The drone can be equipped with a range of payloads, including high-resolution day/night cameras, laser capabilities (pointing and range-finding), and specialized sensors for highly challenging tasks. The drone’s robust design and stable flight characteristics add a new dimension to tactical air support across a variety of scenarios.

From a strategic perspective, the APUS 25 offers significant advantages in terms of force multiplication. Its extended endurance allows a single unit to cover an area that would typically require multiple conventional drones. By combining the flexibility of a multirotor with the endurance of fixed-wing platforms, IAI has created a versatile tool that can adapt to a wide range of mission profiles. As these advanced drones become more prevalent in disaster areas and battlefields, they will likely reshape paramilitary and military doctrine and operational planning.
