The 777-300ER ("ER" for Extended Range) is the C-market version of the -300. It features raked and extended wingtips, a wing aspect ratio of 9.0, a new main landing gear, reinforced nose gear, and extra fuel tanks.It also has a strengthened fuselage, wings, empennage, and engine attachments. The -300ER is powered by the GE90-115B turbofan, which is the world's most powerful jet engine in service, with a maximum thrust of 115,300 lbf (513 kN).Its maximum range is 7,370 nautical miles (13,650 km), made possible by higher MTOW and increased fuel capacity. The -300ER can fly approximately 34 percent farther than the -300 with a full load of passengers and cargo.Following flight testing, aerodynamics refinements have reduced fuel burn by an additional 1.4 percent.
The first -300ER was delivered to Air France on April 29, 2004. The -300ER is the best-selling 777 variant, having surpassed the -200ER in orders in 2010 and deliveries in 2013. Since its launch, the model has been a primary driver of the twinjet's sales past the rival A330/340 series. Using two engines produces a typical operating cost advantage of around 8–9 percent for the -300ER over the A340-600, along with a 20 percent fuel burn advantage over the 747-400. Several airlines have acquired the -300ER as a 747-400 replacement amid rising fuel prices. As of January 2016, -300ER deliveries to 39 different customers totaled 620, with 176 unfilled orders. Operators had 575 aircraft in service as of July 2015. The -300ER's direct Airbus competitors have included the A340-600HGW and the A350-1000.
