The Boeing Vertol CH-46 Sea Knight is a U.S.-designed medium-lift tandem-rotor transport helicopter equipped with dual turboshaft engines. Initially created by Vertol and later produced by Boeing Vertol following Boeing's acquisition of Vertol, its development began in 1956 under the designation Vertol Model 107.

Conceived as a successor to piston-driven rotorcraft such as the H-21 "Flying Banana," the V-107 was pioneering in utilizing turboshaft propulsion. The prototype first took to the air on 22 April 1958. Subsequently, in June 1958, the US Army commissioned ten production models labeled YHC-1A, though this order was later scaled down to three units. By 1961, the United States Marine Corps chose Boeing Vertol's Model 107M to meet its requirements for a medium-lift, twin-engine helicopter capable of transporting cargo and assault troops. Known colloquially as the "Phrog" and officially named "Sea Knight," it served the USMC from the Vietnam War period until its frontline retirement in 2014.

The Sea Knight fulfilled all-weather, day-and-night troop, supply, and equipment transport roles for the USMC until replaced by the MV-22 Osprey during the 2010s. Its operational scope included combat support, search and rescue (SAR), casualty evacuation (CASEVAC), and Tactical Recovery of Aircraft and Personnel (TRAP). The US Navy employed it as a standard medium-lift utility helicopter before transitioning to the MH-60S Knighthawk in the early 2000s. Other international users included Canada (where it was known as CH-113 and primarily assigned to SAR missions until 2004), along with operators in Japan, Sweden, and Saudi Arabia. The civilian variant, designated BV 107-II or "Vertol," features amphibious capabilities, allowing it to land on calm water surfaces and remain afloat temporarily.

Origins

Throughout the 1940s and 1950s, American manufacturer Piasecki Helicopter was at the forefront of developing tandem-rotor helicopters, notably producing the piston-powered H-21 "Flying Banana," an early utility and transport rotorcraft. In 1955, Piasecki was rebranded as Vertol Corporation (derived from vertical take-off and landing) and commenced designing a new tandem rotor helicopter. The 1956 design, internally referred to as Vertol Model 107 or V-107, marked a shift from piston engines to turboshaft powerplants. Construction began that year on a prototype powered by two Lycoming T53 turboshaft engines, each delivering 877 shp (640 kW).

The V-107 prototype completed its maiden flight on 22 April 1958. To showcase its capabilities, Vertol arranged multiple public demonstration flights across both domestic and international venues. In June of that year, the U.S. Army awarded Vertol a contract for ten production aircraft based on the V-107 platform, designated YHC-1A. However, this order was subsequently reduced to three units to divert resources toward developing a larger turbine-powered helicopter known as V-114. All three YHC-1As were outfitted with pairs of GE-T-58 engines. The first YHC-1A flew in August 1959, shortly followed by an enhanced commercial/export variant labeled 107-II.

By 1960, the U.S. Marine Corps sought a medium-lift twin-turbine helicopter for troop and cargo assault missions to replace older piston-engine models. That same year, Boeing acquired Vertol and renamed it Boeing Vertol. After competitive evaluations, Boeing Vertol’s model 107M was selected in early 1961 for Marine Corps service under the designation HRB-1. In 1962, the U.S. Air Force placed an order for twelve XCH-46B Sea Knight helicopters (designated XH-49A) but later canceled this procurement due to delivery delays, opting instead for the competing Sikorsky S-61R.

Following its initial flight in August 1962, the Sea Knight received the official designation CH-46A. By November 1964, both the Marines’ CH-46A and Navy’s UH-46A versions entered active service; the UH-46A was specifically modified for vertical replenishment tasks. The CH-46A was powered by two T58-GE8-8B turboshaft engines rated at 1,250 shp (930 kW) each, enabling it to transport up to 17 passengers or carry cargo loads up to 4,000 pounds (1,815 kg).

Further advancements

Production of the upgraded CH-46D began in 1966, incorporating improved rotor blade designs and more robust T58-GE-10 turboshaft engines, each delivering . This enhancement allowed the helicopter to transport up to 25 personnel or carry of cargo. By the end of 1967, the CH-46D had been deployed to the Vietnam War zone, supplementing the earlier CH-46A models, which were less dependable. The U.S. Navy also procured UH-46Ds for ship resupply missions, while approximately 33 CH-46As underwent remanufacturing to meet CH-46D specifications.

From 1968 through 1971, the U.S. Marine Corps introduced the CH-46F variant, which retained the T58-GE-10 engines but featured updated avionics and other improvements; this represented the final production version. Subsequently, most Sea Knights were modernized to the CH-46E configuration, which included fiberglass rotor blades, strengthened airframes, and upgraded T58-GE-16 engines rated at . Several CH-46Es were further modified to double their fuel capacity. Starting in the mid-1990s, the Dynamic Component Upgrade (DCU) program enhanced drive train components and rotor system controls.

The commercial BV 107-II model was initially ordered by New York Airways in 1960, with three units delivered by July 1962, each accommodating up to 25 passengers. In 1965, Boeing Vertol transferred production rights to Japanese firm Kawasaki Heavy Industries, which manufactured civilian and military variants under the designation KV 107. On 15 December 2006, Columbia Helicopters, Inc acquired the BV 107-II type certificate and collaborated with Piasecki to develop the Model 107-III, a remanufactured version based on older airframes. This updated model is equipped with CT58-GE-16 engines—the commercial counterpart of those used on the CH-46E—and features advanced avionics including a glass cockpit.

Design

The Boeing Vertol CH-46 Sea Knight is a medium-lift tandem-rotor transport helicopter powered by two General Electric T58 turboshaft engines mounted on either side of the rear rotor tower. Power is transmitted to the forward rotor through a drive shaft, with both engines linked so that either can drive both rotors if one engine fails. Each rotor consists of three blades that fold for storage and naval deployment. The helicopter employs fixed tricycle landing gear with dual wheels on each strut, resulting in a nose-up posture that facilitates cargo loading. The two main landing gears are located within rear sponsons that also house fuel tanks holding a total of 350 US gallons (1,438 L).

The cabin primarily comprises a cargo compartment with a rear loading ramp that can be removed or left open during flight for extended cargo or parachute deployment. Utility features include an internal winch designed to pull external cargo on pallets inside the aircraft and an optional belly-mounted cargo hook rated at for external loads; however, payload limits decreased as airframes aged. The standard crew consists of three personnel, though larger teams can be accommodated depending on mission requirements—for instance, search and rescue (SAR) variants operate with five crew members. For defensive purposes, pintle-mounted 0.50 in (12.7 mm) M2 Browning machine guns could be fitted on both sides, with armor plating added during service in Southeast Asia.

The CH-46 possesses limited amphibious capabilities, able to land on water and remain buoyant for up to two hours under calm sea conditions.

United States

Nicknamed the "Phrog," the Sea Knight was actively employed in every operational setting of the U.S. Marine Corps from its debut during the Vietnam War until its retirement in 2015. Its enduring performance and dependability gave rise to phrases such as "phrogs phorever" and "never trust a helicopter under 30." The CH-46 fleet undertook a variety of missions including troop transport, medical evacuation, supply runs to forward arming and refueling points (FARPs), vertical replenishment, search and rescue, as well as recovery of downed aircraft and personnel.

Vietnam War

Throughout the Vietnam conflict, the CH-46 served as a crucial Marine troop carrier, filling the gap between the smaller Bell UH-1 Iroquois and the larger Sikorsky CH-53 Sea Stallion, gradually replacing the UH-34. Early in its deployment, the helicopter experienced significant mechanical challenges; its engines were susceptible to damage from foreign objects stirred up during low-hover operations, leading to compressor stalls and limiting engine life to roughly 85 flight hours. Consequently, on 21 July 1966, all CH-46s were grounded pending installation of improved filtration systems.

On 3 May 1967, a CH-46D crashed at Marine Corps Air Facility Santa Ana, resulting in the deaths of its four crew members. Investigations revealed that failure of the main transmission mounting bracket caused rotor intermeshing, prompting a fleet-wide grounding for inspections. Additional accidents occurred in May and June due to tail pylon failures, causing several fatalities and leading to grounding of all CH-46D models, while CH-46As remained operational. On 31 August 1967, a medical evacuation CH-46A broke apart mid-flight, killing everyone aboard. A subsequent similar event led to grounding except for emergency missions, reducing Marine airlift capacity by half.

A collaborative inquiry by Naval Air Systems Command and Boeing Vertol traced these incidents to structural failures in the rear pylon that resulted in rotor separation. The investigation recommended reinforcing structures and adding strain gauges. Marines and Boeing Vertol personnel modified eighty CH-46As at Marine Corps Air Station Futenma, Okinawa; these upgraded helicopters resumed service by February 1968.

During the 1972 Easter Offensive, Sea Knights played a significant role supporting U.S. and South Vietnamese troop deployments. Marine CH-46s were also involved in Operation Frequent Wind, the April 1975 evacuation of Saigon, with the last helicopter departing from the U.S. embassy roof being a CH-46 from HMM-164. By the conclusion of the conflict, over one hundred Sea Knights had been lost due to enemy action.

Post-Vietnam

In February 1968, the Marine Corps Development and Education Command acquired several CH-46 helicopters for testing herbicide dispersal using HIDAL systems; these trials indicated that redesign was necessary. Tandem-rotor helicopters like the CH-46A were also assessed for deploying Naval Special Forces equipped with Special Atomic Demolition Munition (SADM).

During Operation Urgent Fury in Grenada, Marine CH-46s transported elements of the 8th Marine Regiment, evacuated a downed AH-1 Cobra crewman, and moved infantry from the 75th Ranger Regiment to secure and evacuate American students at St. George's University, although one helicopter crashed after striking a palm tree.

CH-46E Sea Knights saw extensive use by U.S. Marines during the 2003 invasion of Iraq, including a notable extraction mission for Army Private Jessica Lynch. Throughout occupation and counter-insurgency operations in Iraq, they were heavily tasked with CASEVAC duties around the clock. Nevertheless, authors Williamson Murray and Robert H. Scales highlighted persistent reliability problems, maintenance difficulties, and limited lift capacity during deployment. Following numerous helicopter losses in Iraq, Marines equipped their CH-46s with advanced anti-missile defensive systems.

The U.S. Navy officially retired the CH-46 on 24 September 2004, replacing it with the MH-60S Seahawk; however, the Marine Corps continued operating them until transitioning to the MV-22 Osprey. In March 2006, Marine Medium Helicopter Squadron 263 (HMM-263) was redesignated as VMM-263, becoming the first MV-22 squadron. This replacement process extended through other medium helicopter squadrons until completion in 2014. The final U.S. Marine Corps flight of a Sea Knight took place on 5 October 2014 at Marine Corps Air Station Miramar, with HMM-364 conducting its last overseas mission aboard . On 9 April 2015, Marine Medium Helicopter Training Squadron 164 officially retired the CH-46. The USMC formally marked its retirement on 1 August 2015 during a ceremony near Washington DC.

Beginning in April 2011, Navy's Fleet Readiness Center East refurbished retired USMC CH-46Es for use by the United States Department of State Air Wing. Several helicopters from HMX-1 were transferred to this fleet in late 2014. In Afghanistan, these aircraft provided secure transport for State Department personnel; they were outfitted with missile warning sensors, flare dispensers, and armed with M240D or M2 Browning machine guns. A September 2019 report from the State Department Inspector General revealed that operating costs amounted to roughly US$1,500 for every seven minutes of flight time on a CH-46.

Afghanistan Evacuation

During the 2021 Kabul Airlift, seven CH-46 helicopters from the State Department Air Wing were deployed. Prior to the complete withdrawal of U.S. forces, all seven aircraft were rendered inoperable and subsequently left behind at Kabul International Airport, as documented in numerous images and footage. Notably, one of these abandoned CH-46s (BuNo 154038, c/n 2389) had also been involved in Operation Frequent Wind nearly five decades earlier. Although the U.S. State Department faced criticism for abandoning these helicopters, officials explained that the aircraft were being retired due to their age and increasing maintenance difficulties. These seven represented the sole U.S. State Department helicopters remaining at Kabul Airport.

Canada

The Royal Canadian Air Force acquired six CH-113 Labrador helicopters specifically for search and rescue (SAR) operations, while the Canadian Army operated 12 CH-113A Voyageur variants intended for medium-lift transport roles. The Labradors entered active service beginning on 11 October 1963. Following the introduction of the larger CH-147 Chinook in the mid-1970s, the Voyageur fleet was converted to Labrador specifications to enhance SAR capabilities, bringing the total number of Labradors to 15.

Designed with a watertight hull suitable for maritime landings, the Labrador was equipped with a 5,000 kg cargo hook, an external rescue hoist, and a range of 1,110 km. It also featured emergency medical equipment and could carry up to 18 passengers. Its extended range allowed it to support missions for the U.S. Coast Guard and conduct long-distance medical evacuations beyond the reach of USCG helicopters available at that time.

Between 1981 and 1984, Boeing Canada undertook upgrades on six CH-113s and five CH-113As under the SAR-CUP program, installing advanced avionics, weather radar systems, auxiliary power units, high-speed rescue hoists, and searchlights. Despite these enhancements, intense SAR usage combined with harsh operating environments led to increased maintenance expenses by the 1990s, prompting plans for replacement.

In 1992, Canada intended to replace its Labrador fleet with 15 AgustaWestland EH101 helicopters designated as CH-149 Chimo. However, this procurement was canceled in 1993 by the Liberal government, resulting in penalties and extending Labrador service life. After a fatal accident involving a CH-113 during a SAR mission in 1998 heightened calls for new aircraft, an order was placed for 15 EH101-based CH-149 Cormorant helicopters. Deliveries commenced in 2003, enabling full retirement of Labradors by 2004. Subsequently, in October 2005, Columbia Helicopters acquired eight retired CH-113 Labradors to augment their Vertol helicopter fleet.

Sweden

In 1963, Sweden purchased ten UH-46B helicopters from the United States for transport and anti-submarine warfare duties within the Swedish Armed Forces, where they were designated Hkp 4A. A decade later, in 1973, eight Kawasaki-manufactured KV-107 helicopters entered service as Hkp 4B models, replacing the older Piasecki H-21s. Throughout the Cold War period, these helicopters primarily conducted anti-submarine operations and troop transport missions. They also played key roles in search and rescue efforts, including during the rescue operations following the sinking of the MS Estonia in 1994. The Hkp 4A models were phased out during the 1980s and succeeded by Eurocopter AS332 Super Puma helicopters; meanwhile, Kawasaki-built Sea Knights remained operational until 2011 before being replaced by both UH-60 Black Hawk and NH90 helicopters.

Argentina

On 15 September 2023, General Xavier Issac, chief of Argentina’s Air Force, announced a formal request to U.S. authorities seeking authorization to refurbish surplus CH-46 helicopters stored at the 309th Aerospace Maintenance and Regeneration Group facility in Arizona. Additionally, civilian-operated CH-46s are under consideration to support Argentina’s Antarctic bases. These aircraft would serve as replacements for two Mil Mi-171E helicopters acquired in 2010 but now rendered unusable due to sanctions imposed following the Russian invasion of Ukraine.

Civilian and Other Uses

The civilian variant, known as the BV 107-II Vertol, was introduced prior to the military CH-46 model and saw commercial operation with companies such as New York Airways, Pan American World Airways, and later Columbia Helicopters. Its applications ranged from providing commuter flights in the mid-1960s between Manhattan’s Pan Am building rooftop and JFK Airport, to towing a hover barge, as well as assisting in the erection of transmission towers for overhead electrical lines.

In December 2006, Columbia Helicopters acquired the Model 107 type certificate from Boeing with the intention of manufacturing new units. By 2023, Columbia had begun procuring older Model 107-II and CH-46E airframes for refurbishment and resale as Model 107-IIs. Additionally, they have undertaken upgrades of existing airframes, resulting in the Model 107-III variant.
