any idea of what this "space freighter" is ?

The station in third pic look very, very bizarre... ???

A 425 ton payload to LEO ??!!! :eek:
 
thats Boeing HLLV from 1976-79

Boeing also investigated large two-stage vertical takeoff, horizontal landing (VTHL TSTO) heavy-lift reusable launch vehicles for 380-420t payloads. The company's "reference vehicle" from 1976 was used as a baseline for NASA's early SPS technology assessments. Its gross liftoff mass was 11,000t and the payload capability was 420t. The specific transportation cost was $44/kg [1978 economic conditions].
