The Navy has tested hand-deploying sonobuoys from the CH-53E heavy-lift helicopter, resembling early-World War I bomber tactics. The test, announced on Sept. 27, 2024, included crewmembers throwing sonobuoys out of the open cargo door. This tactic provides redundancy for the Navy and increases resources for missions. The aircraft’s flexibility was highlighted, showcasing its ability to handle various payloads. The test will be repeated and certified for the newer CH-53K King Stallion model. The upgrade is part of the U.S. military’s modernization efforts to prepare for potential conflicts in the Pacific, reflecting a shift from counter-insurgency operations.

The recent testing of hand-deploying sonobuoys from the CH-53E heavy-lift helicopter by the United States Navy harkens back to early-World War I bomber tactics, showcasing the versatility and potential of this aircraft in naval operations. The successful test, conducted by Air Test and Evaluation Squadron Two One (HX-21) in collaboration with the Heavy Lift Helicopters Program Office (PMA-261) and Air Anti-Submarine Warfare Systems Program Office (PMA-264), demonstrated the capability of the CH-53E in deploying sonobuoys for anti-submarine warfare missions.
According to Colonel Kate Fleeger (USMC), the Program Manager of the Heavy Lift Helicopters Program Office, the test highlighted the untapped capabilities of the CH-53E and its potential for future operational tasks. The hand-deployment of sonobuoys from the helicopter provides an additional level of redundancy and flexibility for the Navy in completing missions.
Interestingly, the CH-53E Super Stallion, which first flew in 1974, has a long history of service with the U.S. Navy and Marine Corps, as well as the Japan Maritime Self-Defense Force. The helicopter is known for its heavy lift capabilities, powered by three engines to operate its massive seven rotor blades.
Despite its capabilities, the CH-53E has a poor safety record, with multiple crashes over the years raising concerns about its reliability. However, the Navy is moving forward with plans to replace the E-models with the newer CH-53K King Stallion, which offers increased lift capacity and improved performance. The CH-53K is set to deploy for the first time in fiscal year 2025, with the Marine Corps planning to operate 200 of the new helicopters.
The testing of hand-deploying sonobuoys from the CH-53E Super Stallion is part of the Navy’s efforts to modernize and adapt to new challenges in the Pacific region. As the Department of Defense shifts its focus towards potential conflicts with near-peer adversaries, the Navy is exploring innovative tactics and capabilities to maintain its edge in maritime operations.
Fun Fact: The CH-53E Super Stallion is the largest and heaviest helicopter in the U.S. military, capable of carrying a maximum payload of 33,000 pounds. Its impressive lifting power makes it a crucial asset for transporting troops, cargo, and equipment in support of military operations.
