The CH-53K King Stallion lifted the external load of 36,000 lbs./16,330 kg into a hover followed by flight demonstrating satisfactory handling qualities and structural margins. The gross weight of the aircraft topped out at just over 91,000 lbs./41,277 kg, making this the heaviest helicopter ever flown by Sikorsky.

«The successful completion of these last critical envelope expansion tests further demonstrates the maturity of the CH-53K aircraft», said Doctor Michael Torok, Sikorsky Vice President, Marine Corps Systems. «We look forward to bringing this unique and exceptional heavy lift capability to the United States Marine Corps and our international customers».

Prior to the 36,000-lb./16,330 kg lift, the CH-53K King Stallion lifted various external payloads up to 27,000 lbs./12,247 kg including a Joint Light Tactical Vehicle (JLTV). The CH-53K can carry a 27,000 lb./12,247 kg external load over 110 nautical miles/126.6 miles/203.7 km in high/hot conditions, which is more than triple the external load carrying capacity of the legacy CH-53E Super Stallion aircraft. Other flight envelope accomplishments include tethered hover demonstrating flight speeds to 200 knots/230 mph/370 km/h, angle of bank to 60 degrees, takeoffs and landings from sloped surfaces up to 12 degrees, external load auto-jettison, and gunfire testing.

«The payload capability of this helicopter is unmatched, triple that of its predecessor and better than any other heavy lift helicopter in production», said Colonel Hank Vanderborght, U.S. Marine Corps Program Manager for the Naval Air Systems Command’s Heavy Lift Helicopters Program. «The CH-53K program continues on pace to deploy this incredible heavy lift capability to our warfighters».

The CH-53K King Stallion is also garnering international interest. Rheinmetall and Sikorsky recently signed a strategic teaming agreement to offer the CH-53K King Stallion for Germany’s new heavy lift helicopter competition. Additional teammates will be announced in the coming weeks leading up to the aircraft’s debut at the ILA Berlin Air Show in April.

Using the single point hook, the helicopter hovered up to 100 feet/30.5 meters for approximately 10 minutes while carrying the 18,870-pound/8,559-kg vehicle.

«This was a first-of-its-kind event for both the CH-53K and JLTV programs», said U.S. Marine Corps Colonel Hank Vanderborght, program manager for the H-53 Heavy Lift Helicopters program office, PMA-261. «Watching these two high priority programs come together on the flight line was an exceptional sight».

The JLTV family of vehicles are the Army and Marine Corps’ replacement for the High Mobility Multipurpose Wheeled Vehicle (HMMWV) and the CH-53K King Stallion is replacing its predecessor, the CH-53E Super Stallion. The specific JLTV used for the demonstration was the four-seat model, known as the Combat Tactical Vehicle.

Prior to using the JLTV, the program tested various external payloads on the CH-53K King Stallion using representative concrete slabs, up to 27,000 pounds/12,247 kg. This year, the test team will expand that external weight envelope up to 36,000 pounds/16,329 kg.

«The payload capability of this helicopter is unmatched, triple that of its predecessor and better than any other heavy lift helicopter in production», said Vanderborght.

The demonstration was a collaborative effort among the CH-53K Integrated Test Team (Sikorsky, NAVAIR and Air Test and Evaluation Squadron (HX) 21), the NAVAIR Internal Cargo Lab and PMA-261.

In addition, the Helicopter Support Team from Combat Logistics Battalion (CLB) 25 traveled to NAS Patuxent River to support the demonstration, providing key ground support in the hook of the JLTV to the aircraft. It was the first time this unit had an opportunity to support both platforms.

«The biggest thing my unit noticed was the stability of it», said Corporal Ronald Fritter, CLB-25. «Safety is paramount while underneath the bird because you have so many variables with the down wash of the aircraft to the hook … with the hook not moving around at all, little to none, it makes our jobs easier».

There are four Engineering Development and Manufacturing Model aircraft and a Ground Test Vehicle in test. In addition, a sixth aircraft, known as a System Demonstration Test Article, joined the test program this month. To date, the program has logged more than 700 cumulative flight hours.

The 90-minute orientation flight included various operational maneuvers, landings and takeoffs, providing Nin-Nun a firsthand look at the unique and capabilities of the CH-53K King Stallion available through full authority fly-by-wire flight controls.

«This is the first time we have flown an international ally in the CH-53K», said U.S. Marine Corps Colonel Hank Vanderborght, program manager for the H-53 Heavy Lift Helicopters program office, PMA-261. «Flights like this give us an opportunity to strengthen relationships with our allies while sharing a taste of America’s next generation heavy lift helicopter».

The flight was arranged based on a government-to-government request from Brig. Gen. Nin-Nun and made possible through a contract modification between Sikorsky and NAVAIR.

«It was a great honor being hosted by the Marines and having a chance to fly on two outstanding platforms as we ramp up to decide on our future heavy lift», said Nin-Nun.

The orientation flight was conducted during an already planned test flight and piloted by Stephen McCulley, Sikorsky chief experimental test pilot. Prior to the flight, Brigadier General Nin-Nun completed a familiarization flight in the simulator and safety brief prior to take-off.

The two-day visit also included simulator flights, relevant program briefs, and a tour of the NAVAIR Internal Cargo Lab.

Currently, there are four Engineering Development and Manufacturing Model aircraft in test and one Ground Test Vehicle, which have logged more than 606 cumulative flight hours. Initial operational capability remains on pace for 2019 and is defined as having four aircraft, with combat-ready crews logistically prepared to deploy. The DOD’s program of record remains at 200 aircraft.

PMA-261 continually works with international partners through the Foreign Military Sales (FMS) program to potentially meet the international partners’ heavy lift helicopter requirements. FMS aircraft increase the total aircraft procured above the program of record and will decrease the unit cost for all users.

With more than triple the payload capability and a 12-inch/30.5-cm wider internal cabin than its predecessor (CH-53E Super Stallion), the CH-53K’s payload capability can take the form of a variety of relevant payloads ranging from an internally loaded High Mobility, Multipurpose Wheeled Vehicle or the European Fennek armored personnel carrier. In addition, it can handle up to three independent external loads at once, which gives mission flexibility and system efficiency.

«Gaining the U.S. Marine Corps approval to enter into production and the award of the first contract are milestones made possible by the tremendous achievements of the joint Sikorsky, Naval Air Systems Command (NAVAIR) and U.S. Marine Corps team», said Dr. Mike Torok, vice president, CH-53K programs. «This is what we have been striving for – to deliver this amazing capability to the U.S. Marine Corps».

Under the $303,974,406 million contract, Sikorsky will deliver two production aircraft to the U.S. Marine Corps in 2020 along with spares and logistical support. Aircraft assembly will take place at Sikorsky’s headquarters in Stratford, Connecticut.

«We have just successfully launched the production of the most powerful helicopter our nation has ever designed. This incredible capability will revolutionize the way our nation conducts business in the battlespace by ensuring a substantial increase in logistical through put into that battlespace. I could not be prouder of our government-contractor team for making this happen», said Col Hank Vanderborght, U.S. Marine Corps program manager for the Naval Air Systems Command’s Heavy Lift Helicopters program, PMA-261.

The CH-53K King Stallion provides unmatched capability with three times the lift capability of its predecessor, the CH-53E Super Stallion. The helicopter cabin, a full foot wider, gives increased payload capacity to internally load 463L cargo pallets, High Mobility Multipurpose Wheeled Vehicles (HMMWV) or a European Fenneck armored personnel carrier while still leaving the troop seats installed. The CH-53K’s external hook system provides the capability to lift three independent external loads simultaneously. These true heavy lift internal and external cargo improvements give the Marine Corps tremendous mission flexibility and efficiency in delivering combat power in support of the Marine Air Ground Task Force or in delivering humanitarian assistance or disaster relief to those in need.

The CH-53K King Stallion also brings enhanced safety features for the warfighter. Full authority fly-by-wire flight controls and mission management reduce pilot workload enabling the crew to focus on mission execution. Features include advanced stability augmentation, flight control modes that include attitude command-velocity hold, automated approach to a stabilized hover, position hold and precision tasks in degraded visual environments, and tactile cueing. These features permit the pilot to focus confidently on the mission at hand while operating in degraded environments.

The CH-53K’s internal health monitoring systems with fault detection/fault isolation, coupled with a digital aviation logistics maintenance system that interfaces with the Fleet Common Operating Environment for fleet management, provides improved combat readiness for the Marine Corps.

The U.S. Department of Defense’s Program of Record remains at 200 CH-53K King Stallion aircraft. The U.S. Marine Corps intends to stand up eight active duty squadrons, one training squadron, and one reserve squadron to support operational requirements.

The CH-53K King Stallion helicopter flew on June 30 from Sikorsky’s Development Flight Center in West Palm Beach to PAX, a distance of approximately 810 miles/1,307.6 km. Total flight time was six hours, with two en route fuel stops at Naval Air Station Mayport, Florida, and Marine Corps Air Station New River, North Carolina.

«This first movement of CH-53K flight testing to our customer’s facility denotes that the aircraft have achieved sufficient maturity to begin transitioning the focus of the test program from envelope expansion to system qualification testing», said Doctor Michael Torok, Sikorsky Vice President, CH-53K Programs. «This has been the plan from the beginning and is another important step toward getting these fantastic aircraft into the hands of the U.S. Marine Corps».

The four CH-53K Engineering Development Model (EDM) aircraft have already completed more than 450 hours of flight testing at Sikorsky’s Development Flight Center in West Palm Beach, and continue to drive to the edges of the operational envelope with both internal and external loads. The flight test program will continue to operate as it has from the beginning under an Integrated Test Team (ITT) that is comprised of Sikorsky, U.S. Navy Naval Air Systems Command (NAVAIR), and U.S. Marine Corps (USMC) personnel. Testing will continue in both locations, West Palm Beach and Patuxent River throughout the transition period.

«Bringing the CH-53K flight test program to PAX is an exciting milestone; many of the employees dedicated to its advancement now have the opportunity to work right down the street from it», said Colonel Hank Vanderborght, U.S. Marine Corps program manager for the Naval Air Systems Command’s Heavy Lift Helicopters program, PMA-261.

In April, the CH-53K King Stallion Program successfully passed its Defense Acquisition Board (DAB) and achieved a Milestone C decision that approves funding for low rate initial production.

The CH-53K King Stallion provides unmatched heavy lift capability with three times the lift of the CH-53E Super Stallion that it replaces. With the increased payload capability and a 12-inch/30.5-centimetre wider internal cabin compared to the predecessor CH-53E Super Stallion, the CH-53K’s increased payload capability can take the form of a variety of relevant payloads ranging from multiple U.S. Air Force standard 463L pallets to an internally loaded High Mobility Multipurpose Wheeled Vehicle (HMMWV) or a European Fennek armored personnel carrier. In addition, the CH-53K King Stallion can carry up to three independent external loads at once providing incredible mission flexibility and system efficiency.

The CH-53K King Stallion offers enhanced safety features for the warfighter. Safety is enhanced with full authority fly-by-wire flight controls and mission management that reduces pilot workload and enables the crew to focus on mission execution because the CH-53K King Stallion all but «flies itself». Features include advanced stability augmentation, flight control modes that include attitude command-velocity hold, automated approach to a stabilized hover, position hold and precision tasks in degraded visual environments, and tactile cueing that all permit the pilot to confidently focus on the mission at hand.

Further, the CH-53K King Stallion has improved reliability and maintainability that exceeds 89 percent mission reliability with a smaller shipboard logistics footprint than the legacy CH-53E Super Stallion.

The U.S. Department of Defense’s Program of Record remains at 200 CH-53K King Stallion aircraft. The first six of the 200 Program of Record aircraft are under contract and scheduled to start delivery next year to the Marine Corps. Two additional aircraft, the first low rate initial production aircraft, are under long lead procurement for parts and materials, with deliveries scheduled to start in 2020. The Marine Corps intends to stand up eight active duty squadrons, one training squadron, and one reserve squadron to support operational requirements.

«This affirmative Milestone C decision validates the maturity and the robust capability of the King Stallion in meeting the United States Marine Corps mission requirements», said Doctor Michael Torok, Sikorsky vice president, CH-53K King Stallion Programs. «This establishes the CH-53K King Stallion as a production program and marks another critical step toward our goal of delivering this tremendous capability to the USMC».

Numerous, successfully completed pre-requisites preceded the Milestone C decision. Supplier as well as prime contractor Production Readiness Reviews took place throughout 2016 to establish the program’s readiness to move into low rate initial production. Aircraft maturity was established well in advance with over 400 flight hours achieved, and the October 2016 initial Operational Assessment by the USMC fully established the ability of the CH-53K King Stallion to achieve critical mission flight and ground scenarios in the hands of active duty Marines. Overall, post evaluation interviews of aircrew, ground crew and flight surgeons revealed a high regard for the operational capability demonstrated by the CH-53K King Stallion.

«We have just successfully launched the production of the most powerful helicopter our nation has ever designed. This incredible positive step function in capability is going to revolutionize the way our nation conducts business in the battlespace by ensuring a substantial increase in logistical throughput into that battlespace. I could not be prouder of our government-contractor team for making this happen», said Colonel Hank Vanderborght, U.S. Marine Corps program manager for the Naval Air Systems Command’s Heavy Lift Helicopters program, PMA-261.

The CH-53K King Stallion provides unmatched heavy lift capability with three times the lift of the CH-53E Super Stallion that it replaces. With more than triple the payload capability and a 12-inch wider internal cabin compared to the predecessor, the CH-53K King Stallion’s increased payloads can range from multiple U.S. Air Force standard 463L pallets to an internally loaded High Mobility Multipurpose Wheeled Vehicle (HMMWV) or a European Fennek armored personnel carrier, to up to three independent external loads at once.

«This successful operational assessment by the Marine Corps is a clear sign of the maturity and the robust capability of the King Stallion», said Dr. Michael Torok, Sikorsky Vice President CH-53K Programs. «This was a key requirement in support of the upcoming Milestone C decision, and its success is another important step in our transition from development into production».

The U.S. Marine Corps’ initial operational testing included external lift scenarios of 27,000 lbs/12,200 kg in hover and a 12,000 lbs/5,422 kg 110 nautical mile/126.6 miles/204 km radius mission. Ground events included embarkation/debarkation of combat equipped troops, internal and external cargo rigging, Tactical Bulk Fuel Delivery System (TBFDS) operation and medevac litter configuration.

Overall, post evaluation interviews of aircrew, ground crew and flight surgeons revealed a high regard for the operational capability demonstrated by the CH-53K King Stallion. This customer assessment is a pre-requisite to Milestone C and is intended to minimize risk to successfully pass the U.S. Marine Corps operational evaluation (OPEVAL) phase for a future full rate production decision.

«OT-B1 (Operational Test) is a critical milestone for the program because this is the first time an operational test has been done utilizing an ’All Marine’ crew», said Colonel Hank Vanderborght, U.S. Marine Corps program manager for Naval Air Systems Command’s Heavy Lift Helicopters Program. «All test objectives were met, and the aircraft performed very well. This further increases our confidence in the design, and is another key step to successfully fielding the CH-53K».

The operational testing was based out of the Sikorsky Development Flight Center (DFC) in West Palm Beach, Florida, where CH-53K development flight test is continuing to make excellent progress now with all four Engineering Development Model (EDM) aircraft in flight status.

The CH-53K King Stallion will carry three times the external payload of the predecessor CH-53E Super Stallion equating to a 27,000-pound external load over 110 nautical miles/126.6 miles/204 km under «high hot» ambient conditions. The CH-53K King Stallion helicopter provides unmatched heavy lift capability with reduced logistics footprint and reduced support costs over its entire life cycle. CH-53K King Stallion pilots can execute heavy lift missions more effectively and safely in day/night and all weather with the King Stallion’s modern glass cockpit. Fly-by-wire flight controls facilitate reduced pilot workload for all heavy lift missions including external loads, maritime operations, and operation in degraded visual environments. With more than triple the payload capability of the predecessor CH-53E Super Stallion, the King Stallion’s increased capability can take the form of a variety of relevant payloads ranging from an internally loaded High Mobility Multipurpose Wheeled Vehicle (HMMWV) to up to three independent external loads at once which provides outstanding mission flexibility and system efficiency. A locking, U.S. Air Force pallet compatible cargo rail system reduces both effort and time to load and unload palletized cargo.

The U.S. Department of Defense’s Program of Record remains at 200 CH-53K King Stallion aircraft. The first four of the 200 «Program of Record» aircraft are scheduled for delivery next year to the U.S. Marine Corps, with another two aircraft to follow. Two additional aircraft are under long lead procurement for parts and materials, with deliveries scheduled to start in 2020 The Marine Corps intends to stand up eight active duty squadrons, one training squadron, and one reserve squadron to support operational requirements.

This press release contains forward looking statements concerning opportunities for development, production and sale of helicopters. Actual results may differ materially from those projected as a result of certain risks and uncertainties, including but not limited to changes in government procurement priorities and practices, budget plans, availability of funding and in the type and number of aircraft required; challenges in the design, development, production and support of advanced technologies; as well as other risks and uncertainties including but not limited to those detailed from time to time in Lockheed Martin Corporation’s Securities and Exchange Commission filings.

27,000 Pound

Lockheed Martin on June 23 announced the Sikorsky CH-53K King Stallion successfully completed an external lift of a 27,000 pound/12,247 kg payload at Sikorsky’s Development Flight Test Center in West Palm Beach, Florida.

The aircraft executed an «Out of Ground Effect» (OGE) external load test at 100 feet/30.5 m above the ground while performing hover maneuvers to demonstrate its excellent control authority in this flight regime. An OGE load is the most stressful of lift conditions for a helicopter from a power required standpoint. OGE is defined as an altitude greater than the helicopter’s main rotor diameter (79 feet/24 m in the King Stallion’s case) where power demand greatly increases due to loss of the benefit of ground effect.

«This 27,000 pound/12,247 kg external lift is yet another key milestone for the program», said Doctor Michael Torok, Sikorsky Vice President, CH-53K Programs. «The King Stallion achieved this external lift with ease, and we are on track to successfully complete the initial operational assessment this year».

Sikorsky, a Lockheed Martin Company, is developing the CH-53K King Stallion heavy lift helicopter for the U.S. Marine Corps.

The Sikorsky CH-53K has already achieved speeds exceeding 140 knots/161 mph/259 km/h, and a third Sikorsky CH-53K King Stallion helicopter has joined the flight test program thereby accelerating the pace to full aircraft maturity and production. The first two aircraft have already verified the King Stallion’s capabilities well in excess of the predecessor Sikorsky CH-53E Super Stallion. A fourth King Stallion is currently in final preparation for flight status and on track to join the flight test program this summer.

«Lifting 27,000 pounds/12,247 kg in OGE conditions is another key milestone for the program, which further confirms our confidence in the design and performance of the aircraft», said Colonel Hank Vanderborght, U.S. Marine Corps Program Manager for the Naval Air Systems Command’s Heavy Lift Helicopters Program. «This is the most strenuous condition we had to demonstrate from a performance standpoint prior to achieving Milestone ’C’ and entering production».

The King Stallion will carry a 27,000 pound/12,247 kg external load over 110 nautical miles/126.6 miles/203.7 km at 91.5°F/33°C at an altitude of 3,000 feet/914.4 m – a U.S. Navy operational requirement for «high hot» conditions. The Sikorsky CH-53K King Stallion helicopter will provide unmatched heavy lift capability with reduced logistics footprint and reduced support costs over its entire life cycle.

CH-53K pilots can execute heavy lift missions more effectively and safely in day/night and all weather with the King Stallion’s modern glass cockpit. Fly-by-wire flight controls reduce pilot workload for all heavy lift missions including external loads, maritime operations, and operation in degraded visual environments. With more than triple the payload capability of the predecessor CH-53E, the King Stallion’s increased capability can accommodate a range of payloads from an internally loaded High Mobility Multipurpose Wheeled Vehicle (HMMWV) up to three independent external loads at once, providing wide mission flexibility and system efficiency. Additionally, a locking U.S. Air Force pallet compatible cargo rail system reduces both effort and time to load and unload palletized cargo.

The U.S. Department of Defense’s Program of Record remains at 200 Sikorsky CH-53K King Stallion aircraft. The first four of the 200 are scheduled for delivery next year to the USMC. An additional four aircraft are under long lead procurement for parts and materials with delivery scheduled in 2019. USMC initial operating capability is scheduled for 2019. The U.S. Marine Corps intends to stand up eight active duty squadrons, one training squadron, and one reserve squadron to support operational requirements.

This press release contains forward looking statements concerning opportunities for development, production and sale of helicopters. Actual results may differ materially from those projected as a result of certain risks and uncertainties, including but not limited to changes in government procurement priorities and practices, budget plans, availability of funding and in the type and number of aircraft required; challenges in the design, development, production and support of advanced technologies; as well as other risks and uncertainties including but not limited to those detailed from time to time in Lockheed Martin Corporation’s Securities and Exchange Commission filings.

First External Load

April 20 Lockheed Martin announced the CH-53K King Stallion helicopter has achieved its first external lift flight by successfully carrying a 12,000-pound/5,443-kg external load.

«Achieving our first external lift signifies another milestone for the CH-53K program», said Mike Torok, Sikorsky’s Vice President of CH-53K Programs. «Our flight envelope expansion efforts remain on track, and we continue to make good progress toward our initial operational test assessment later this year, and ultimately full aircraft system qualification».

The first two CH-53K King Stallion heavy lift helicopters achieved their first flights on October 27, 2015, and January 22, 2016, respectively. To date these helicopters have achieved over 50 flight hours combined including one flight at speeds over 140 knots/161 mph/260 km/h. The third and fourth King Stallion aircraft will join the flight test program this summer.

As the King Stallion flight test program proceeds, both of the current flying aircraft will be exercised to expand the external load envelope. Initial external payloads weighing 12,000 pounds/5,443 kg will be flown first in hover and then incrementally to speeds up to 120 knots/138 mph/222 km/h. The aircraft will then carry 20,000 pound/9,072 kg and 27,000 pound/12,247 kg external payloads.

The CH-53K King Stallion is equipped with single, dual and triple external cargo hook capability that will allow for the transfer of three independent external loads to three separate landing zones in support of distributed operations in one single sortie without having to return to a ship or other logistical hub. The three external cargo hooks include a single center point hook with a 36,000 pound/16,329 kg capability and dual-point hooks each capable of carrying up to 25,200 pound/11,430 kg.

The system features an electrical load release capability from the cockpit and cabin, and a mechanical load release capability at each of the pendant locations. An auto-jettison system is incorporated to protect the aircraft in the event of a load attachment point failure.

«It is exciting to have achieved our first external lift, another important step towards fielding the most powerful U.S. military helicopter», said Colonel Hank Vanderborght, U.S. Marine Corps Program Manager for Heavy Lift Helicopters. «Our program continues on pace to deploy this incredible heavy lift capability to our warfighters».

Sikorsky Aircraft, a Lockheed Martin company, is developing the CH-53K King Stallion heavy lift helicopter for the U.S. Marine Corps. The CH-53K King Stallion maintains similar physical dimensions and «footprint» as its predecessor, the three-engine CH-53E Super Stallion helicopter, but will more than triple the payload to 27,000 pounds/12,247 kg over 110 nautical miles/126.6 miles/204 km under «high hot» ambient conditions.

Features of the CH-53K King Stallion helicopter include a modern glass cockpit; fly-by-wire flight controls; fourth-generation rotor blades with anhedral tips; a low maintenance elastomeric rotor head; upgraded engines; a locking, United States Air Force pallet compatible cargo rail system; external cargo handling improvements; survivability enhancements; and improved reliability, maintainability and supportability.

The U.S. Department of Defense’s Program of Record remains at 200 CH-53K King Stallion aircraft. The U.S. Marine Corps intends to stand up eight active duty squadrons, one training squadron, and one reserve squadron to support operational requirements.

The second King

Sikorsky, a Lockheed Martin Company, announced on March 14 the second CH-53K King Stallion helicopter has joined the flight test program and achieved first flight. In addition, the first aircraft into the test program has achieved flight envelope expansion to 120 knots/138 mph/222 km/h for the U.S. Marine Corps’ CH-53K King Stallion heavy lift helicopter program.

«Adding a second aircraft into flight status signifies another milestone for the CH-53K program», said Mike Torok, Sikorsky’s vice president of CH-53K King Stallion Programs. «With both aircraft in flight test, our flight envelope expansion efforts will accelerate as we continue to make good progress toward our initial operational test assessment and full aircraft system qualification».

The first and second CH-53K King Stallion heavy lift helicopter Engineering Development Models (EDM) achieved their first flights on October 27, 2015, and January 22, 2016, respectively. To date these helicopters have achieved over 35 flight hours combined including multiple flights with an active duty USMC pilot at the controls. As the flight test program proceeds, these two flying CH-53K helicopters will be joined by two additional aircraft to complete flight qualification of the USMC’s next generation heavy lift capability over an approximately three-year flight test program.

These first two aircraft are the most heavily instrumented of the Engineering Development Models (EDM) and will focus on structural flight loads and envelope expansion. When the other two EDM aircraft join the flight line in 2016 they will focus on performance, propulsion and avionics flight qualification.

«It is exciting to have two CH-53K helicopters flying», said Colonel Hank Vanderborght, U.S. Marine Corps program manager for Heavy Lift Helicopters. «Our program continues on pace to deploy this incredible heavy lift capability to our warfighters».

Sikorsky is now developing the CH-53K King Stallion heavy lift helicopter for the U.S. Marine Corps. The King Stallion maintains similar physical dimensions with a reduced «footprint» compared to its predecessor, the three-engine CH-53E Super Stallion helicopter, but will more than triple the payload to 27,000 pounds/12,247 kg over 110 nautical miles/126.6 miles/204 km under «high hot» ambient conditions.

Features of the CH-53K King Stallion helicopter include a modern glass cockpit; fly-by-wire flight controls; fourth-generation rotor blades with anhedral tips; a low maintenance elastomeric rotor head; upgraded engines; a locking, United States Air Force pallet compatible cargo rail system; external cargo handling improvements; survivability enhancements; and improved reliability, maintainability and supportability.
