The 777-200ER ("ER" for Extended Range) is an extended range version and the B-market model of the original 777-200. This means it could fly longer than the original version. Although the number of passengers able to be carried remains the same, the range of the -200ER is increased to 7725 nautical miles (14,305 km). 422 -200ER were made, with no -200ER waiting to be made.
