In 2010, Boeing announced plans to increase production from 5 aircraft per month to 7 aircraft per month by mid-2011, and 8.3 per month by early 2013. Complete assembly of each 777-300ER requires 49 days. The smaller Boeing 787 Dreamliner, the first stage of a replacement aircraft initiative called the Boeing Yellowstone Project, entered service in 2011. Reportedly, the 777 could eventually be replaced by a new aircraft family, Yellowstone 3, which would draw upon technologies from the 787. In November 2011, assembly began on the 1,000th 777, a -300ER model for Emirates, which was rolled out in March 2012.
