A gas turbine engine turbine assembly includes a high pressure spool (33) having a high pressure turbine (24) drivingly connected to a high pressure compressor (18) by a high pressure shaft (27) which is rotatable about an engine centerline (8). A low pressure turbine (26) has counter rotatable low pressure inner and outer shaft turbines (41 and 42) drivingly connected to coaxial low pressure inner and outer shafts (130 and 140) respectively which are at least in part rotatably disposed co-axial with and radially inwardly of the high pressure spool (33). The low pressure inner shaft turbine (41) is drivingly connected to a forward fan blade row (13) by the low pressure inner shaft (130). The low pressure outer shaft turbine (42) is drivingly connected to a aft fan blade row (15) by the low pressure outer shaft (140). A single direction of rotation booster (16) is drivenly connected to the low pressure outer shaft (140) and axially located aft and downstream of the aft fan blade row (15).
