![]() ![]() report says the weapons system was used in Libya in March 2020. Yet, if the Global Hawk is successful in its new role, it could encourage new types of missions for drones.A Kargu rotary-wing attack drone loitering munition system manufactured by the STM defense company of Turkey. Or, it might turn out that using a 30-year-old U2-R manned ISR aircraft makes more sense for hypersonic tests. A high-altitude, long-range, and long-endurance drone might be useful for tracking a test glider during its descent. In the case of boost-glide hypersonic vehicles, a rocket ascends high in the atmosphere, almost to the edge of space, and then releases a glider, which can descend at speeds faster than Mach 20. Politics aside, a business case can be made for using the Global Hawk for hypersonic tests. “Our state will have more aircraft than before due to the entire Block 20 and Block 30 fleets being at Grand Sky, while at the same time, we will have a stronger national defense as the Sky Range program will significantly enhance our ability to test and develop hypersonic missiles.” “The transfer of the Global Hawk Block 30 fleet to Grand Sky is a win for both Grand Forks and our entire nation,” Senator Hoeven said. Hoeven’s office took credit for both transfers. The Block 30s will be joining four Block 20s that were transferred to Grand Sky last year. The RQ-4 carries the Battlefield Airborne Communications Node which acts as a persistent gateway, bridging diverse tactical data links and voice communications to improve battlefield communications. Rob Donnelly, 380th Aircraft Maintenance Squadron, conducts pre-flight checks on an RQ-4 Global Hawk Unmanned Aerial Vehicle before its first launch from an undisclosed location in Southwest Asia, Nov.

The Air Force will continue to operate the more advanced Block 40 model. In 2019, Iran shot down a Global Hawk over the Persian Gulf with an anti-aircraft missile, and then recovered the wreckage to develop its own drones.Īdditionally, the Air Force itself was not enthused with the Block 30 model: In 2012, it concluded that Block 30 was less capable than a manned U-2 surveillance plane. However, critics were not impressed by the performance of the $130 million drones, which they considered to be both expensive and vulnerable to threats such as surface-to-air missiles. Various models included an array of sensors, including synthetic aperture radar, cameras, and signals intelligence collectors. ![]() It could fly at 60,000 feet to deliver high-altitude ISR (intelligence, surveillance, and reconnaissance) data. It had a takeoff weight of 16 tons, a range of 12,000 miles, and a 131-foot-wide wingspan (seven feet wider than that of a Boeing 737 airliner. The Northrop Grumman RQ-4 Global Hawk, which first took flight in 1998, was the poster child for big, expensive unmanned aircraft. The Global Hawks’ ending is both practical and sad. Sky Range would replace the ships, which are expensive to operate, with modified Global Hawks that could deploy quickly and increase testing capacity through the creation of additional testing corridors in the Pacific and elsewhere,” Senator Hoeven added. ![]() Additionally, this process signals the testing schedule to our adversaries. “DoD is only able to conduct four to six tests per year, as it takes several weeks to deploy and position the ships for each test. “Currently, the Department of Defense (DoD) uses an aging fleet of ships deployed across a Pacific Ocean corridor to test hypersonic missiles,” according to a press release by Senator John Hoeven of North Dakota. Their name will also change from the majestic-sounding “Global Hawk” to the uninspiring “Range Hawk.” There, they will serve as high-altitude, long-range airborne observers to record test data during hypersonic launches. All 20 aircraft of the Block 30 model of the RQ-4B were sent to the Air Force’s Test Resource Management Center’s (TRMC) Sky Range hypersonic missile testing program at Grand Sky, a drone station at Grand Forks Air Force Base, North Dakota. ![]()
