Triton demonstrates Arctic Ocean navigation capability

The successful test flight demonstrated the system’s ability to operate in the harsh environment over the Arctic Ocean, providing critical intelligence, surveillance, reconnaissance and targeting capabilities in the “High North”.

The RAAF received its first Triton in June, and the aircraft, designated AUS1, is expected to provide the Australian Defence Force with long-range, persistent surveillance across Australia’s maritime approaches and its broader areas of interest.

Triton’s advanced technological design makes it the only autonomous high-altitude, long-endurance aircraft capable of operating at altitudes above 50,000 feet for durations of more than 24 hours, Northrop Grumman said.

Jane Bishop, vice-president and general manager, global surveillance division, Northrop Grumman, explained the importance of this test flight, saying, “Flight operations in austere and frigid conditions present unique navigation challenges. Our demonstration highlights Triton’s ability to successfully perform in that challenging environment.”

The test flight, which began in Deadhorse, Alaska, and flew within 100 miles of the North Pole, leveraged Northrop Grumman’s proprietary navigation systems, mission management computer and upgraded operational flight programs to demonstrate Triton’s ability to navigate the Arctic.

Northrop’s test aircraft collected navigation data during the five-hour flight and remained within US and Canadian airspace for the duration. It provided an important validation for ground-based GPS alignment and initialisation procedures to enable operations from runways above 70 degrees north latitude.

US Navy Captain and the service’s Triton program manager, Josh Guerre added: “Arctic regions are an increasingly important theatre of operations with unique threats and environments. We are ready to support those mission sets for domestic and international customers.”

Triton’s higher operating altitude of more than 50,000 feet enables operations above inclement weather that would limit medium-altitude platforms to 10,000–30,000 feet.

The platform’s de-icing and anti-icing capabilities ensure it’s mission-ready and capable of operations in extreme arctic conditions, enabling it to support a wide range of missions, including maritime patrol, signals intelligence and search and rescue.
