Terminal B – originally named Sheremetyevo-1 – has two iterations.

The first iteration was constructed and opened on 3 September 1964.
The terminal, as Sheremetyevo-1, was known for its "flying-saucer"-like design, and was nicknamed "shot glass" by locals.
Being 200 metres (660 ft) long and 40 metres (130 ft) wide, as well as having a volume exceeding 100,000 cubic metres (3,500,000 cu ft), the terminal can hold up to 800 people per hour.
Formerly serving international flights, Sheremetyevo-1 would transition to serving domestic flights.
Along with other Sheremetyevo terminals that underwent Latin lettering conventions, Sheremetyevo-1 was renamed Terminal B on 28 March 2010.
Terminal B was then demolished in August 2015 to be reconstructed as a larger and more modern terminal which began in October 2015.

The new terminal B commenced its operations on 3 May 2018, with the Aeroflot's flight to Saratov.
All airlines that have domestic flights from Sheremetyevo and some flights of Aeroflot began shifting to Terminal B from Terminal D. Compared to the previous terminal B, that was demolished, new terminal will have an increased passenger capacity of 20 million passengers and will serve domestic flights only.
As of November 2018, Aeroflot has consolidated all of its domestic services at Terminal B, with the exception of flights to far eastern destinations in Vladivostok, Khabarovsk and Petropavlovsk-Kamchatsky.
Flights to the eastern Russian shore and some short-haul (including all domestic flights served by widebodies) continue out of SVO's Terminal D.
The terminal is connected by an interterminal underground passage with Sheremetyevo's southern terminals and the Aeroexpress railway station.
