The Vostok design was modified to permit carrying multi-cosmonaut crews, and flown as two flights of the [[Voskhod programme]]. The cylindrical interior cabin was replaced with a wider, rectangular cabin which could hold either three cosmonauts seated abreast (Voskhod 1), or two cosmonauts with an inflatable airlock in between them, to permit [[extravehicular activity]] (Voskhod 2). A backup solid-fuel retro rocket was added to the top of the descent module. Vostok's ejection seat was removed to save space (thus there was no provision for crew escape in the event of a launch or landing emergency). The complete Voskhod spacecraft weighed {{convert|5682|kg|lb}}.

Lack of space meant that the crew members of Voskhod 1 did not wear [[space suit]]s.<ref>{{cite book|last=Siddiqi|first=Asif A.|url=https://history.nasa.gov/SP-4408pt1.pdf|title=Challenge To Apollo: The Soviet Union and the Space Race, 1945-1974|year=2000|publisher=NASA|authorlink=Asif Azam Siddiqi|location=US |isbn=1780393016|page = 423}}</ref>  Both Voskhod 2 crew members wore spacesuits, as it involved an EVA by cosmonaut [[Alexei Leonov]]. An airlock was needed because the vehicle's electrical and environmental systems were air-cooled, and complete capsule depressurization would lead to overheating. The airlock weighed {{cvt|250|kg|lboz}}, was {{cvt|700|mm}} in diameter, {{cvt|770|mm}} high when collapsed for launch. When extended in orbit, it was {{cvt|2.5|m|ftin}} long, had an internal diameter of {{cvt|1|m}} and an external diameter of {{cvt|1.2|m|ftin}}. The second crew member wore a spacesuit as a precaution against accidental descent module depressurization. The airlock was jettisoned after use.

The lack of ejection seats meant that the Voskhod crew would return to Earth inside their spacecraft unlike the Vostok cosmonauts who ejected and parachuted down separately. Because of this, a new landing system was developed, which added a small solid-fuel rocket to the parachute lines. It fired as the descent module neared touchdown, providing a softer landing.
