Boeing’s newest and longest Dreamliner, the 787-10, is a step closer to welcoming its first passengers. A brand new 787-10 destined for Singapore Airlines’ fleet just rolled out of the assembly line Tuesday morning in Charleston, South Carolina.While the first ever 787-10 rolled out back in February, that aircraft’s mission was to go through the rigorous tests that new aircraft must pass to become certified, which it is still undergoing. It will eventually be retrofitted for customers and end up in regular passenger service. The one that rolled out od Charleston Tuesday will be the first to enter service.Image courtesy of Josh Drake / Boeing.Built for 787-10 launch customer Singapore Airlines, the aircraft still needs to be painted and undergo “system checks, fueling, and engine runs,” a Boeing statement said, before it’s ready to be delivered “in the first half of 2018.” This will be the first of 30 aircraft on firm order by the airline, with a letter of intent to purchase another 19. SQ plans to put its new jets in service on regional routes in Asia and to Australia, which can still get quite long. The 787-10 has a maximum range of 7,400 miles or 11,900 km, according to Boeing.Image courtesy of Josh Drake / Boeing.Stretched 18 feet longer than the Boeing 787-9, this 787-10 will offer 14% more seats than the -9 and 36% more than the original 787-8.
