First Flight

Sikorsky Aircraft Corp., a subsidiary of United Technologies Corp., on October 27 announced the successful first flight of the U.S. Marine Corps’ CH-53K King Stallion heavy lift helicopter prototype, known as Engineering Development Model-1 (EDM-1). The 30-minute flight signals the beginning of a 2,000-hour flight test program using four test aircraft.

«EDM-1’s first flight signifies another major milestone for the CH-53K helicopter program», said Mike Torok, Sikorsky’s CH-53K Program Vice President. «Having independently tested the aircraft’s many components and subsystems, including integrated system level testing on the Ground Test Vehicle, we are now moving on to begin full aircraft system qualification via the flight test program».

Sikorsky delivered the EDM-1 into the test program at the company’s West Palm Beach, Florida-based Development Flight Center in late 2014. During its 30 minute maiden flight the EDM-1 aircraft performed hover, sideward, rearward and forward flight control inputs while in ground effect hover up to 30 feet above the ground. As the flight test program proceeds, the EDM-1 will be joined by an additional 3 EDM aircraft to fully expand the King Stallion’s flight envelope over the course of the three-year flight test program.

«We have entered a much anticipated phase in this developmental program», said Colonel Hank Vanderborght, U.S. Marine Corps Program Manager for Heavy Lift Helicopters. «We have experienced significant learning at the system and sub-system levels, which continues to build our confidence in the capabilities of the 53K. With first flight behind us, we look forward to execution of the development and operational testing and the deployment of this incredible heavy lift capability to our warfighters».

Sikorsky, with support of others in the industry, is developing the CH-53K King Stallion heavy lift helicopter for the U.S. Marine Corps. The CH-53K King Stallion helicopter will maintain similar physical dimensions as its predecessor, the three-engine CH-53E Super Stallion helicopter, but will nearly triple the payload to 27,000 pounds/12,247 kg over 110 nautical miles/126.6 miles/203.7 km under «high hot» ambient conditions. Features of the CH-53K 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 aircraft with an Initial Operational Capability in 2019. Eventual production quantities would be determined year-by-year over the life of the program based on funding allocations set by Congress and the U.S. Department of Defense acquisition priorities. The Marine Corps intends to stand up eight active duty squadrons, one training squadron, and one reserve squadron to support operational requirements.

Australian Romeo

Two of the Royal Australian Navy’s (RAN) MH-60R Seahawk helicopters were loaded onto a Royal Australian Air Force (RAAF) C-17 at Air Test and Evaluation Squadron (HX) 21 at Naval Air Station (NAS) Patuxent River, Maryland, for delivery to their new home in Australia May 27, 2015. These two Seahawks mark the halfway point for the U.S. Navy’s foreign military sales agreement with the Commonwealth of Australia for training and production of 24 MH-60R Seahawk helicopters, which began in June 2011.

«As they come off the production line, the Australians have picked them up two at a time», said Commander Scott Stringer, HX-21 MH-60R government flight test director. «This is a multi-year plan that should carry into mid-2016. We are delivering brand new aircraft to the Australians. They still have that new car smell with very few flight hours».

RAN squadron 725 is in the process of establishing MH-60R operations at NAS Nowra, New South Wales. Later this year, HX-21 and RAN squadron 725 are scheduled to test unique modifications on the MH-60Rs. These modifications are based on unique RAN requirements and include the addition of an instrument landing system and a crash-survivable data recorder. The collaborative U.S. and RAN test and evaluation of the MH-60R modifications also allows for an open exchange of professional views and experiences.

Because of interoperability – how the two navies have trained and operated together – Stringer explained how he could foresee a U.S. Navy H-60 pilot seamlessly operating during a cross-deck tour on an Australian ship or vice versa.

«We have six people supporting the MH-60R acquisition and sustainment effort at Pax River and share office space with the RAAF Classic Hornet and Super Hornet sustainment team», said Commander Andrew Dawes, RAN MH-60R project resident team lead. «This is something we take a great deal of pride in and greatly appreciate the support that everyone at NAS Pax River is providing in this process».

The mission of HX-21 is to conduct the highest quality developmental flight test and evaluation of rotary-wing and tilt-rotor aircraft, airborne systems in support of all U.S. Navy and U.S. Marine Corps training, operational combat and operational combat support missions.

MH-60R Seahawk (Romeo)

The MH-60R «Romeo» is the most capable and mature Anti-Submarine (ASW)/Anti-Surface Warfare (ASuW) multi-mission helicopter available in the world today. Together with its sibling, the MH-60S «Sierra», the Seahawk variants have flown more than 650,000 hours across a 500+ aircraft fleet. The MH-60R Seahawk is deployed globally with the U.S. Navy fleet and a growing number of allied international navies.

The journey from the start of MH-60R Seahawk flight-testing through the first deployment, in 2009, of 11 MH-60R helicopters aboard the USS Stennis, represents 1,900 flight hours, the equivalent of 500 labor years, and a considerable financial commitment by Lockheed Martin.

The MH-60R Seahawk, manufactured by Sikorsky Aircraft Corp, and equipped with advanced mission systems and sensors by Lockheed Martin Mission Systems and Training (MST), is capable of detecting and prosecuting modern submarines in littoral and open ocean scenarios.

In addition, MH-60R Seahawk is capable of conducting stand-alone or joint Anti-Surface Warfare missions with other «Romeo» or MH-60S «Sierra» aircraft. Secondary missions include electronic support measures, search and rescue, vertical replenishment, and medical evacuation.

The advanced mission sensor suite developed and integrated by Lockheed Martin includes:

  • APS-147 Multi-mode radar (including Inverse Synthetic Aperture Radar);
  • AQS-22 Airborne Low Frequency Dipping Sonar (ALFS) subsystem and sonobuoys;
  • ALQ-210 Electronic Support Measures with an integrated helo threat warning capability;
  • AAS-44 Forward Looking Infrared Electro-Optical device;
  • Integrated self-defense;
  • A weapons suite including torpedoes and anti-ship missiles.

Lockheed Martin MST also produces the Common Cockpit avionics, fielded on both the MH-60R «Romeo» and MH-60S «Sierra». The 400th Common Cockpit will be installed on the first Royal Australian Navy MH-60R. In 2012, the Common Cockpit exceeded 600,000 flight hours across an operational fleet of 360 aircraft. The digital, all-glass cockpit features four large, flat-panel, multi-function, night-vision-compatible, color displays. The suite processes and manages communications and sensor data streaming into MH-60 multi-mission helicopters, presenting to the crew of three actionable information that significantly reduces workload while increasing situational awareness.

The U.S. Navy is committed to a long-term preplanned product improvement program, also known as P3I, to keep the MH-60R Seahawk current throughout its life. Recent upgrades have included vital software and mission management systems in the Situational Awareness Technology Insertion (SATI) package as well as design upgrades to the Identification Friend-or-Foe Interrogator Subsystem. Combined with the aircraft’s Automatic Radar Periscope Detection and Discrimination system, the MH-60R’s range of detection will expand – enhancing situational awareness and advanced threat detection – while interference with civil air traffic control systems will diminish.

The MH-60R Electronic Surveillance Measures (ESM) system, which provides aircrew with valuable threat-warning capabilities, has benefited from the installation and maintenance of an ESM autoloader, and the development of Mission Data Loads, which comprise a database of possible threats within a specific region of operations.

Smaller elements are included as well, including the integration of a new multi-function radio called the ARC210 Gen 5 (which sister-aircraft MH-60S «Sierra» will also receive), crucial spare assemblies and integration of other core technologies. The Gen 5 radio will provide MH-60R Seahawk aircrew with flexible and secure communication.

Survivability and crashworthiness are not just attributes of the Seahawk helicopter, they are inherent to the design. A strict military standard makes the Seahawk helicopter a rugged and extremely durable helicopter that delivers safety. Safety that has been proven in real missions, around the world. Some of our aircraft have over thirty years of service and continue to support operations in the most rigorous of environments known to man.

Sikorsky launched the S-97 Raider helicopter program in September 2010, with objectives of maturing the Collier-Award winning X2 rotorcraft configuration and demonstrating a helicopter that meets current U.S. Army special operations and armed reconnaissance needs, while maturing technologies for Future Vertical Lift (FVL). The program is 100 percent industry-funded by Sikorsky Aircraft and its 53 industry partners.

Based on the X2 coaxial rotor design, the Raider helicopter is capable of being developed into a unique multi-mission configuration that is able to carry six troops and external weapons. The coaxial counter-rotating main rotors and pusher propeller are expected to provide cruise speeds up to 240 knots/276 mph/444 km/h.

«Based on the capabilities that were demonstrated today, Sikorsky is positioned to develop the S-97 Raider helicopter’s game-changing capabilities to enable helicopter forces to out-perform on the battleground of tomorrow», said Samir Mehta, President of Sikorsky Defense Systems & Services. «With the Raider aircraft’s unmatched combination of speed, maneuverability and acoustic signature, Sikorsky Aircraft is ideally positioned to provide the military with essential mission-specific capabilities. With this flight, we have started the demonstration of solutions to not only near-term capability gaps but also solutions for future vertical lift needs».

The second S-97 Raider helicopter prototype is on track to complete final assembly in 2015. A demonstration tour of the Raider helicopter is planned for 2016.

X2 technology is scalable to a variety of military missions including light assault, light attack, armed reconnaissance, close-air support, combat search and rescue, and unmanned applications

The delegates also had the opportunity to visit Sikorsky’s Development Flight Center (DFC), site of full system testing of the heavy lift helicopter. The NATO group was able to see the CH-53K Ground Test Vehicle (GTV), a prototype tethered to the ground. The delegation was also able to view the CH-53K Engineering Development Model 1 (EDM 1), one of four flight test aircraft.

The visit wrapped up with delegates getting a chance to see the first of two prototypes of the S-97 Raider helicopter, developed by Sikorsky to demonstrate the military application of Sikorsky’s X2 Technology. A second Raider prototype will serve as a demonstrator aircraft, offering key customers an opportunity to experience the capabilities of X2 Technology first hand. The Raider helicopter is a rigid coaxial rotor prototype aircraft ideally suited for armed reconnaissance and a wide range of special operations missions. The coaxial counter-rotating main rotors and pusher propeller provide cruise speeds beyond 220 knots/253 mph/407 km/h, more than double the speed of conventional helicopters in this size class.

The visit to Sikorsky was part of the delegation’s semi-annual meeting taking place in West Palm Beach, Florida.

«We are delighted that our honored NATO guests can be here in West Palm Beach to experience, first-hand, our energy and enthusiasm for our CH-53K aircraft», said Mike Torok, Sikorsky’s CH-53K Program Vice President. «The CH-53K King Stallion is destined to fulfill a significant role in the international heavy lift arena for decades to come».

NATO Committee Chairman Hans-Peter Mueller said the visit provided an opportunity to see the CH-53K helicopter in full scale and appreciate its capabilities. «We thank Sikorsky for its hospitality. The delegates enjoyed the informative tour and recognize the value of spending time with the designers and engineers building this heavy lift helicopter», said Mueller.

Sikorsky leads an industry team developing the CH-53K heavy lift helicopter for the U.S. Marine Corps. The aircraft’s 88,000-pound/39,916 kg maximum gross weight is designed to triple the external load carrying capacity of the CH-53E Super Stallion aircraft to more than 27,000 pounds/12,247 kg over a mission radius of 110 nautical miles/204 km under «high hot» ambient conditions.

U.S. Marine Corps Colonel Hank Vanderborght, H-53 Program Manager at the Naval Air Systems Command, said the CH-53K helicopter program will expand the fleet’s ability to move more material and more rapidly using proven and mature technologies. «Our allies will benefit from the U.S. Marine Corps investment in this next generation heavy lift platform», said Col. Vanderborght. «The CH-53K represents not just the continuation of heavy lift capability but a transformation of what we can do to ensure the Marine Corps remains the most ready force».

Sikorsky continues to conduct tests on four flight test aircraft at its facilities in West Palm Beach and Stratford, Connecticut.

The delegation was also able to view the CH-53K Engineering Development Model 1 (EDM 1), one of four flight test aircraft

Sikorsky CH-53K King Stallion

The CH-53K model will be the world’s premier heavy lift helicopter, leveraging the lessons learned over 50 years of manufacturing and operational success with Sikorsky CH-53A/D/E predecessors. Built to thrive in the modern battlefield, the extremely capable CH-53K aircraft will be intelligent, reliable, low maintenance and survivable across the full spectrum of operating conditions for which it was designed. Expeditionary in nature, the CH-53K aircraft will be fully shipboard compatible and capable of operating from austere and remote forward operating bases. The CH-53K helicopter is the Marine Corps’ critical land and sea based logistics connector.

Helicopters to Poland

According to Jaroslaw Adamowski, DefenseNews.com correspondent, Poland’s Ministry of Defense has obtained three offers in its much-awaited tender to acquire some 70 new helicopters for the country’s armed forces. The bidders include:

  • Airbus Helicopters;
  • Sikorsky;
  • PZL-Swidnik – a Poland-based subsidiary of AgustaWestland.
Airbus Helicopters EC-725 Caracal (also named Super Cougar)
Airbus Helicopters EC-725 Caracal (also named Super Cougar)

«The next phase of the tender will be to perform an analysis of the submitted documents by the commission which is carrying out this procedure, and to select the best offer and test the helicopter», Col. Jacek Sonta, the spokesperson for the Defense Ministry, said in a statement.

A consortium led by Airbus Helicopters is offering the EC-725, while Sikorsky wants to supply its S70i Black Hawk, and AgustaWestland is offering the AW-149.

The Airbus Helicopters EC-725 Caracal (also named Super Cougar) is a long-range tactical transport helicopter developed from the Super Puma/Cougar family for military use. It is a twin-engined aircraft and can carry up to 29-seated troops along with 2 crew, depending on customer configuration. The helicopter is marketed for troop transport, casualty evacuation, and combat search and rescue duties, and is similar to the civilian EC-225.

The Sikorsky S-70i Black Hawk is an international military version assembled by Sikorsky subsidiary, PZL-Mielec in Poland. It was developed for the U.S. Army in the 1970s, winning a competition to be designated the UH-60 Black Hawk and spawning a large family in United States military service. New and improved versions of the UH-60 have been developed since. Civilian versions and some military versions of this medium transport/utility helicopter are produced under various S-70 model designations.

The AgustaWestland AW149 is a medium-lift military helicopter being developed by AgustaWestland. On 20 June 2011, AgustaWestland announced the AW189, a civilian development of the AW149, for service in 2013.

The new helicopters are designed to replace the Polish military’s Soviet-designed Mil Mi-8, Mi-14 and Mi-17 old helicopters.

Local newspaper Rzeczpospolita reported that the planned deal is estimated to be worth up to 10 billion zloty ($2.8 billion).

According to the ministry, the helicopters are to be supplied in three variants, including:

  • Multi-Task Transport;
  • Search-And-Rescue;
  • Anti-Submarine.

«Following the signature of an offset deal, it will become possible for us to sign a contract for the delivery of the helicopters. Under the plan, this will happen in the second half of 2015», Sonta said.

Deliveries are scheduled for 2017 to 2022.

Sikorsky flies to India

As I mentioned earlier, India is clearly moving away from the Russian arms market. The Indian government decided to mass-produce the new main battle tank Arjun instead of buying Russian T-90. The Indian Air Force announced the French Air Fighter as the preferred bidder in the competition with the Su-30MKI and contracted for 126 Rafales, services, and parts could be worth as much as $20 billion. In fine, the latest P-8I Neptune (Indian version of Boeing P-8 Poseidon) delivery was part of an eight-aircraft contract worth $2.1 billion awarded in January 2009 to replace India’s ageing Russian Tupolev Tu-142Ms.

MH-60S delivery for Thai Navy
MH-60S delivery for Thai Navy

In light of the above, the last post by Sikorsky Aircraft Corp. looks like a logical continuation of this clear trend. Namely, India’s Navy has selected Sikorsky to fulfill the service’s Multi-Role Helicopter requirement for anti-submarine and anti-surface warfare (ASW/ASuW), among other maritime roles. Negotiations will now begin to procure 16 S-70B Seahawk helicopters, with an option for 8 additional aircraft, along with a complete logistics support and training program (Source: Sikorsky Aircraft Corp.).

«India’s selection of the S-70B helicopter represents a major strategic win for Sikorsky in an important growth market, and positions us well for future opportunities», said Mick Maurer, President of Sikorsky Aircraft. «We look forward to a long-term collaboration with the Indian Government and local industry as we work to bring the Indian Navy the highly advanced multi-role S-70B aircraft».

The proposed Indian Navy S-70B helicopter variant will include avionics and flexible open architecture Weapons Management Systems that integrate an advanced sonar, 360-degree search radar, modern air-to-surface missiles, and torpedoes for the ASW role. A blade and tail fold capability will facilitate shipboard storage.

The new S-70B aircraft will also enhance the Indian Navy’s capabilities to perform non-combat maritime roles, including search and rescue, utility and external cargo lift, surveillance and casualty evacuation.

Sikorsky has fielded increasingly more capable variants of the S-70B helicopter since 1984 for navies that prefer to acquire a modern, fully integrated ASW/ASuW platform direct from the manufacturer. Now operational in 6 countries (in Europe, Middle East, Asia and Latin America), the S-70B platform has a solid reputation for highly reliable shipboard operations and maintenance while operating aboard frigates and larger naval vessels. The S-70B aircraft is part of Sikorsky’s Seahawk helicopter family (including the SH-60 and MH-60 models) that has accumulated almost 4 million flight hours from more than 800 operational aircraft, and is considered one of the safest platforms available.

At the same time, it should be noted that some Navy experts consider this contract as a rather «strange» deal. The fact is that India didn’t procure the latest MH-60R production standard like other navies. Instead, India’s Navy has elected to go for a direct commercial purchase of S-70B helicopters. Thus, India has lost all benefiting from a standard configuration, a larger component and spares pool, and the financial and sustainment advantages of the Foreign Military Sales channel, which has been used for India’s other recent large arms purchases from the US.

I can give as an assumption that India’s Navy is going to use the S-70B platform with flexible open architecture for specific purposes. Based on the Sikorsky S-70B, Indian engineers can create helicopters with original avionics and weapons systems.
