Boeing has completed detailed design for the 787-10 Dreamliner, achieving another major milestone in the development of the newest and longest member of the 787 family. Boeing engineers reached the key milestone nearly two weeks ahead of schedule.

Major assembly of the 787-10 will begin in 2016, followed by first flight in 2017 and first delivery in 2018.

As a straightforward stretch of the 787-9, which entered service in 2014, Boeing designed the 787-10 for superior efficiency as well as maximum commonality.

95% of the design and build of the 787-10 and 787-9 will be identical, reducing complexity, cost and risk across the production system and providing operational benefits to customers.

The 787-10 is the third and longest member of the 787 family. With a range of 6,430 nautical miles (11,910 km), the 787-10 will cover more than 90% of the world's twin-aisle routes at a whole new level of fuel efficiency: 25% more fuel efficient than the airplanes it will replace and at least 10% better than anything offered by the competition for the future.

To date, the Boeing 787-10 has logged 164 orders from nine customers around the world, accounting for 14% of all 787 orders.
