In December 2005, pushed by the interest of Emirates and Qantas, Boeing was studying the possibility of stretching the 787-9 further to seat 290 to 310 passengers. This variant would be similar to the capacity of the Airbus A350-900 and Boeing 777-200ER. Customer discussions were continuing in early 2006. Mike Bair, Boeing's vice president and general manager for the 787 development program at the time, said it was easier to proceed with the 787-10 development after other customers followed Emirates' request.
On May 30, 2013, Singapore Airlines (SIA) became the launch customer by stating it would order 30 787-10s (provided Boeing launched the program), to be delivered in 2018–2019. On June 18, 2013, Boeing officially launched the 787-10 at the Paris Air Show, with orders or commitments for 102 aircraft from Air Lease Corporation (30), Singapore Airlines (30), United Airlines (20), British Airways (12), and GE Capital Aviation Services (10),
The variant was envisioned as replacing Boeing 777-200, Airbus A330 and Airbus A340 aircraft. The -10 is to compete against the Airbus A350-900, and offer better economics than the A350 on shorter routes, according to Boeing. Steven Udvar-Hazy said "If it's identically configured, the -10 has a little bit of an edge on the -900", but smaller than Boeing's estimate of 10 percent. The 787-10 is to be 224 ft (68 m) long, seat 330 passengers in a two-class cabin configuration, and have a range of 6,430 nmi (11,910 km; 7,400 mi).
Boeing completed detailed design for the -10 on December 2, 2015.[288] Major assembly began in March 2016. Designers targeted 90% commonality between the 787-9 and -10 and achieved 95%; the 18-ft stretch was reached by adding 10 ft forward of the wing and 8 ft aft, and by strengthening the fuselage for bending loads in the center wingbox. Because of the length and additional tail strike protection needed, a semilevered landing gear enables rotation over the aft wheels rather than at the bogie center, like the 777-300ER, and the cabin air conditioning system has 15% more capacity. The first and third -10s have Rolls-Royce's new Trent 1000 TEN engines, while the second is powered by the competing General Electric GEnx-1B engine.
Major fuselage parts were received for final assembly on November 30, 2016. The 787-10's mid-fuselage sections are too large for transport to Everett, Washington and it is built only in Charleston, South Carolina; it is the first Boeing airliner assembled exclusively there. The first -10 was rolled out on February 17, 2017. The variant's first flight took place on March 31, 2017 and lasted 4 hours and 48 minutes.
The first test 787-10 aircraft is engaged in flight envelope expansion work and the second joined the program in early May 2017, while the third with a passenger cabin interior to test the uprated environmental control system and Trent fuel-burn performance was scheduled to join in June. The -10 was scheduled to appear at the 2017 Paris Air Show. The second -10 is being used to prove the GE Aviation engines and the third made its first flight on June 8, 2017, when the flight-test programme was 30% complete. Boeing finished final assembly and painting of the first production 787-10 in October 2017, before its certification. The flight tests are mainly ahead of schedule, with the last stages focused on fuel burn validation and revised flight control software, the phase should be completed in December 2017 and could advance first deliveries earlier than expected in 2018.
At the start of the November 2017 Dubai Air Show the 787-10 had 171 orders; Emirates committed to 40 787-10s, in two- and three-class cabins for 240 to 330 passengers, to be delivered from 2022 and with conversion rights to the smaller 787-9. These aircraft are adapted for 7–8.5 hour missions, in a 280-seat three–class layout. Emirates' Tim Clark was doubtful it would meet its MTOW for the payload-range required with initial 70,000–72,000 lbf (310–320 kN) thrust engines, but with the current 76,000 lbf (340 kN) turbofans and the -9 early margins gave the -10 "stellar economics".
In January 2018, the -10 was certified by the FAA after testing for 900 flight hours. Boeing received its production certificate on February 15. It was first delivered to launch customer Singapore Airlines on March 25, 2018. Fitted with 337 seats, 36 in business and 301 in economy, the -10 began commercial service on April 3, 2018.
The 8.7% fuselage stretch from the -9 to the -10 likely increased empty weight at a lower rate than the 7.4% growth from the -8 to the -9 due to the 10.7% stretch. Software increases the tailplane effectiveness to avoid modifying it. With the same wing but a longer fuselage than the -9, the flutter margin was reduced for the -10 but to avoid stiffening the wing or adding wingtip counterweights for commonality, software oscillates the elevators in the flaps up vertical mode suppression system (F0VMS), similar to the vertical gust load alleviation.
