Everett, Wash., April 6, 2004 -- Boeing [NYSE:BA] has selected two engine types, the General Electric GENX and Rolls-Royce Trent 1000, for its all-new Boeing 7E7 Dreamliner, an airplane that will provide the world's airlines with exceptional efficiency and environmental performance.
Boeing's decision follows months of collaboration with the leading manufacturers of large commercial airplane engines.
"The General Electric and Rolls-Royce engines will enable the 7E7 to fly higher, faster, farther, cleaner, quieter and more efficiently than comparable airplanes," said 7E7 Senior Vice President Mike Bair. "Having an engine choice is a key consideration for our customers. We're now offering two excellent options for the 7E7."
Both engine types will be capable of providing between 55,000 and 70,000 lbs. of thrust, which will allow the three planned 7E7 models to use the same basic engines.
The 7E7 will reduce fuel use -- and associated emissions -- by 20 percent over today's comparably sized airplanes. The engines are key contributors to the airplane's dramatic efficiency improvements. The engines will also help the 7E7 be significantly quieter than today's airplanes and meet new industry requirements.
"All three engine manufacturers presented exceptional proposals," Bair said. "We reached this major milestone well ahead of our original schedule due to the close collaboration on requirements, capabilities and technologies. While it was a challenging decision, the speed with which we made it is representative of the customer interest and the overall momentum on the 7E7 program."
For the first time in commercial jet history, both engine types will use the same standard interface with the airplane, allowing any 7E7 twinjet to be fitted with either engine at any point in time. Engine interchangeability makes the 7E7 a flexible asset that can easily be moved among carriers, an attractive feature for financiers, leasing companies and airlines. Other 7E7 innovations include the elimination of traditional bleed air systems in favor of an efficient, more-electric architecture.
General Electric's new engine, called the GENX (GE Next Generation), is derived from the ultra-high-thrust GE90 engine, which has a proven track record on twin-engine aircraft. The GENX technologies include composite fan blades, the highest pressure-ratio compressor in aviation, and a unique single-annular combustor (where compressed air and fuel are mixed) to achieve dramatically lower emissions. The GENX will have its first full-engine test in 2006. The engine is being designed and tested at GE Transportation's world headquarters in Evendale, Ohio. Final assembly will occur in Durham, N.C.
"Our engine for the 7E7 represents the culmination of new technologies for which GE has made considerable investments over many years," said David Calhoun, president and CEO of GE Transportation. "Needless to say, this is one of the biggest days in the history of our jet engine business."
Rolls-Royce will produce a new variant of its successful, high-thrust Trent engine series to power the 7E7, the Trent 1000. Designed to deliver optimum performance with minimum development risk, it will be the fifth member of the Trent family to enter service, once again featuring the three-shaft design layout unique to Rolls-Royce. The engine will be the most efficient and environmentally advanced Trent ever built.
Mike Terrett, president of Civil Aerospace for Rolls-Royce, said, "This is a special day in the long and rewarding relationship between our companies. Now, once again, our focus is on bringing a new generation of Trent successfully to market."
Boeing is continuing to receive strong customer support for the 7E7 and has submitted a number of firm contract proposals to airlines. The company expects to launch the new airplane this year.
The 7E7 is a family of three airplanes, all of which will use the same engine type. The baseline version will carry 217 passengers in three-classes of seating with a range of up to 8,500 nautical miles (15,700 kilometers). The shorter-range 7E7 will carry 289 passengers in two-class seating on ranges up to 3,500 nautical miles (6,500 kilometers). The stretch version of the 7E7 will carry 257 passengers in three classes with a range of 8,300 nautical miles (15,400 kilometers).
It is being designed to provide customers with a better flying experience including and improved cabin environment with more room and more conveniences.
GE Transportation, a business unit of General Electric Company, is the world's leading manufacturer of jet engines for civil and military aircraft, including engines produced by CFM International, a 50/50 joint company of Snecma Moteurs and GE. GE also manufactures gas turbines, derived from its highly successful jet engine programs, for marine and industrial applications. In addition, GE Aircraft Engines provides comprehensive maintenance support, through its GE Engine Services operation, for GE and non-GE jet engines in service throughout the world.
Rolls-Royce plc operates in four global markets - civil aerospace, defense aerospace, marine and energy. It is investing in technology and capability that can be exploited in each of these sectors to create a competitive range of products. The company has made rapid and substantial gains in market share over recent years and has a total of 54,000 gas turbines in service. Its customer base includes 500 airlines and 4,000 corporate and utility aircraft and helicopter operators, 160 armed forces and more than 2,000 marine customers, including 50 navies. Energy customers span 120 countries. Income from aftermarket services has increased by 60 percent in the past five years and currently accounts for half the group's revenues.

East Hartford, Conn. -- Pratt & Whitney President Louis R. Chenevert
today sent the following letter to all employees regarding Boeing's
engine selection for the 7E7 aircraft.
"Today, we were informed by the Boeing Company that Pratt & Whitney's
PW-EXX engine was not selected to power the 7E7 Dreamliner. While we
are disappointed, we should thank the entire PW-EXX team for their
outstanding efforts in this hard-fought competition. The PW-EXX was
the only all-new engine for the 7E7 and the team supported it with an
extremely competitive and creative business proposal. We should be
proud of everyone who worked on the PW-EXX team and applaud their
passion and commitment.
Pratt & Whitney engines power a number of Boeing aircraft, and we
will continue to strengthen our relationship with the Boeing Company
on these programs. We will also use the advanced technologies we
developed for the PW- EXX engine to pursue other opportunities in the
commercial engine market.
Please keep in mind that Pratt & Whitney has other strengths in the
commercial engine business. The V2500, from International Aero
Engines, won more than $2.5 billion in new business in 2003 and IAE
just received an order to power up to 95 new aircraft for Spirit
Airlines. Pratt & Whitney has two new engines in development, the
PW6000 for single aisle aircraft and, with GE as a partner, the
GP7000 for wide body aircraft. These three programs will be
generating revenues for decades.
Pratt & Whitney also has a commanding presence in military engines
with the F117 engine for the C-17 Globemaster III transport, the F119
engine for the F/A-22 Raptor and the F135 engine for the F-35 Joint
Strike Fighter. We also won a landmark order to power Boeing's new
767 tanker with our PW4062 engines.
Pratt & Whitney Canada is currently developing engines for several
new aircraft. Their PW600 family, which powers the Cessna Citation
Mustang and the Eclipse 500, has the potential to revolutionize air
travel. Space Propulsion, Power Systems and Specialty Materials &
Services give us opportunities outside our traditional aircraft
There are tremendous growth opportunities in aftermarket services
across the company. Pratt & Whitney's aftermarket revenues have
increased by nearly 50 percent over the last decade. Commercial
Engines has already won significant fleet management programs from
United Airlines, Shanghai Airlines and Pakistan International
Airlines so far this year. And we have an opportunity to double our
aftermarket revenues across the company over the next five years.
Pratt & Whitney is a great company, with gifted people who are truly
passionate about the business. We will continue to pursue our growth
strategy and our quest for perfect quality. I am confident we will
prosper in the long run."

Firings, if well done, are good for employee morale.
