Boeing has rolled out the first Rolls-Royce Trent 1000-equipped 787-10 built for Singapore Airlines at its final assembly facility in North Charleston, South Carolina, the company announced Tuesday.

The airplane will now undergo painting of the airline’s livery and begin its system checks, fueling and engine runs. Singapore Airlines expects to take delivery of its first 787-10 in the first half of next year and soon after deploy it on medium-haul routes.

Singapore Airlines serves as the launch customer of the 787-10 and now has placed firm orders for 30 of the airplanes. The airline also signed a letter of intent in February to buy another 19.  

A straightforward 18-foot stretch of the 787-9, the 787-10 retains 95 percent design and build commonality with its smaller sibling while adding some 40 seats in exchange for range. Boeing lists the 330-seat 787-10’s range at 6,430 nautical miles, while the 787-9 operates to a range of 8,500 nautical miles. A pair of Rolls-Royce Trent 1000-10s powered the first 787-10 test airplane on its maiden flight in March. The company also offers General Electric GEnx turbofans for the biggest Dreamliner.

The mid-body section, which accounts for 10 feet of the fuselage stretch, does not fit into Boeing’s Dreamlifter cargo airplanes, meaning it would prove too long for efficient transport from North Charleston—the site of systems installation—to the Everett, Washington facility for final assembly. Separately, said Boeing, introducing the 787-10 in North Charleston takes advantage of that facility’s considerable capacity while allowing the Everett plant to continue improving productivity on the 787-8 and 787-9.

The South Carolina facility fabricates and assembles composite Section 47, the last passenger section of the airplane, and Section 48, which integrates the horizontal and vertical stabilizers and the aft pressure bulkhead, for all Dreamliners built in Everett and North Charleston. It also joins and integrates mid-body fuselage sections from other suppliers. Spirit AeroSystems in Wichita, Kansas, provides 787 forward fuselage sections to both Everett and North Charleston.
