General Electric wins $517 million contract to build engines for Army’s next generation helicopters

By:

WASHINGTON — General Electric Aviation beat the Advanced Turbine Engine Company — a Honeywell and Pratt & Whitney team — to win the $517 million award for the engineering, manufacturing and development phase of the Improved Turbine Engine Program, or ITEP.

“We are honored to be chosen by the Army to continue powering their Black Hawks and Apaches for decades to come,” said Tony Mathis, president and CEO of GE Aviation's military business. “We've invested the resources and infrastructure to execute immediately, and our team is ready to get to work on delivering the improved capabilities of the T901 to the warfighter.”

The fierce competition started more than a decade ago, and its outcome will influence Army rotorcraft for decades to come. GE's T901 engine is now set to replace the T700 used by the Army's legacy utility and attack helicopters, but could also potentially outfit the Army's next generation reconnaissance helicopter in the Future Vertical Lift family of systems.

“The requirements documents for the [Future Attack Reconnaissance Aircraft] specifiesTHE ITEP engine. It has got the FVL stamp of approval,” Jim Thomson, Jr., acting deputy director for the Army's future vertical lift cross functional team, told Defense News in a recent interview.

ITEP answers a number of problems that emerged as the Army operated Apaches and Black Hawks during combat in Afghanistan and Iraq. The AH-64 and UH-60 became heavier as the service added armor and other upgrades during wartime, and they flew in hotter conditions and higher altitudes than would normally be optimal.

“The helicopters were originally designed to work at 4,000 feet on a 95-degree day, and they were flying them much higher than that,” Mike Sousa, GE's business development leader for advanced turboshaft engines, told Defense News in December 2018. “When you do that, you just don't have as much power from the engine.”

The Army's requirements for ITEP were clear throughout the process: Design a 3,000 shaft horsepower engine that reduces fuel consumption by 25 percent and increases its service life by 20 percent compared to the T700, a 2,000 shaft horsepower engine.

Both companies were awarded risk reduction contracts in August 2016, with ATEC getting $154 million and GE Aviation getting $102 million to further refine their designs. Both companies had already spent years conceptualizing new engines and developing novel tech.

GE, the incumbent manufacturer of the T700, offered a single spool engine. Sousa said that configuration would help the company meet weight requirements while removing cost and complexity from the design.

“Our fundamental approach there was how do we keep this engine as affordable as possible and as low weight as possible,” he told Defense News in 2018.

“Helicopters are unique in that they fly into very dirty environments, very austere environments, unprepared landing strips, unprepared surfaces,” added Ron Hutter, GE's executive director of the T901 program. “They generate a lot of dust. You really want to look at the simplicity of the architecture in terms of maintainability. That's another aspect that drove us to stick with the single-spool configuration.”

GE estimates that it's spent $9 billion in testing technologies relevant to the T901.

ATEC had proposed a double spool engine it dubbed the T900.

“We were disappointed to learn that the U.S. Army did not select our offering,” said Craig Madden, president of ATEC. “We believe that we offered the most advanced, capable and lowest risk engine for ITEP for the Army to improve the overall performance of its Apache and Black Hawk fleets.”

    NATO official warns EU force would be ‘unwise’

    By: Joe Gould HALIFAX, Canada — A top uniformed NATO official warned Friday the European Union army concept endorsed by French President Emmanuel Macron and German Chancellor Angela Merkel would be “duplicative” and “unwise.” In an interview at the Halifax International Security Forum, UK Air Marshal Sir Stuart Peach, chairman of the NATO Military Committee, pointed to NATO's strength as a single set of forces, with a unique command and control network and planning process. “It's not rhetoric based. It's real planning based on real data,” Peach said. “And therefore, why would you wish to duplicate or replicate the strengths of an existing strong alliance.” The comments came after Merkel on Tuesday floated the idea of a “real, true European army,” to compliment NATO during a speech before a session of the European Parliament. Those remarks virtually echoed Macron's call a week earlier, in an interview with Europe 1. U.S. President Donald Trump called Macron's comments “very insulting” in a spate of Twitter posts as the two held a meeting last week in Paris. Trump himself has tested the strained bonds with some of America's closest allies by pressuring NATO allies to rely less on the U.S. and dedicate a greater percentage of their gross domestic products to defense. On Tuesday, NATO Secretary General Jens Stoltenberg alluded the proposal of a European force at a NATO conference in Berlin, saying he welcomed, “increased EU efforts on defense, because I think that can actually help to strengthen NATO.” European allied militaries can act without the U.S. so long as they use NATO command structures, Stoltenberg said. “It will be not a wise decision by all those nations who are members of both NATO and the European Union to start to have two sets of command structures, or duplicate what NATO is doing,” Stoltenberg said. On Friday, Peach referred to Stoltenberg's remarks, saying, “Of course, as chairman of the military committee, I agree with [Stoltenberg]. It's unwise to duplicate.” Peach emphasized that NATO has a, “single set of forces, and in our processes, those forces are trained, and assured and certified by NATO.” At the conference, Peach had a broader message that the alliance's 29 members member remain committed to it — and that it is adapting with the times. “Throughout the history of the alliance there have been inevitable tussles about how to go forward,” Peach said. “But throughout as a military alliance, we have adapted our command and control structure, responded to new challenges, embraced new members and continued to adapt to new types of warfare and new threats.” Separately, Finland and Norway intend to launch diplomatic discussions with Moscow over suspected GPS signal-jamming by Russia's military, which overlapped with NATO's Trident Juncture exercises, the largest maneuvers in the High North since the end of the Cold War. Peach on Friday would not confirm the interference took place, but called the principle of freedom of navigation, “very, very important, both to NATO and the International community.” “Freedom of navigation is not just freedom of navigation at sea, so we need to analyze claims with data. And anything that interrupts freedom of navigation is important to be reported," he said. How to manage and operate within the electromagnetic spectrum are important topics that deserve more attention, he said. https://www.defensenews.com/global/europe/2018/11/17/nato-official-warns-eu-force-would-be-unwise/
