The '''Vehicle Assembly Building''' (abbr. '''VAB''', sometimes wrongly called "Vertical Assembly Building") is a large construction facility at [[Kerbal Space Center]]. It is used for designing rockets and other spacecraft in a vertical orientation. [[Parts]] can be placed singly or with two-, three-, four-, six- and eightfold radial symmetry as opposed to the [[SPH]]'s bilateral symmetry. Vessels constructed in the VAB will launch from the [[launch pad]]. [[Kerbal]] scientists, engineers, and utility vehicles roam through the VAB, in addition to cargo lifts, with various animations although they do not affect the design process. Occasionally, the utility vehicles will drive through one another.

The '''Vehicle Assembly Building''', commonly called the '''VAB''' (sometimes wrongly "''Vertical'' Assembly Building"), is one of the two [[craft]] construction facilities at [[Kerbal Space Center]]. It is quite obviously inspired by NASA's real world [[w:Vehicle Assembly Building|Vehicle Assembly Building]].
  
−
With {{version|0.22}} it can store sub assemblies which can be attached to other vehicles later. Those sub assemblies are shared between the VAB and SPH allowing to exchange craft between then.
+
It is the [[KSC]]'s tallest and single largest building, and situated at the heart of the complex. In [[Kerbal Space Program]] game development history, it can also be considered the oldest.

== Description ==
+
== Usage ==
−
The VAB is a large cubical assembly bay located at the very center of [[KSC]]. Large yellow doors act as auxiliary entrances and are located at the north, west, and south faces of the building. On the north side however, there is a giant shutter that spans the whole height of the building. This shutter makes way for all vehicles that are created inside the VAB. There is also a small complex that juts out of the south side. There are stairs and ladders that lead to the roof of the VAB, but dismounting the tops of the ladders is difficult. On the roof, there are 2 helipads beside the skylights. There are no helicopters in the game as of yet, but the pads can be landed on by VTOL vehicles, like the stock [[Rocket-power VTOL]]. If a kerbal jumps off of the VAB roof, they will survive, but may temporarily glitch on landing, with the arms shooting outward and becoming thing for a few seconds.  It is similar to the effects experienced when falling into [[Jool]].
+
Like its counterpart the [[Spaceplane Hangar]] (SPH), the [[Vehicle Assembly Building]] is for craft construction. The [[parts]] list is the same in both facilities. Also, while it keeps its own list of saved craft files and [[Subassembly|subassemblies]] of parts, these can all be cross-loaded between the [[VAB]] and SPH.  
 +
 
 +
There are essential differences between the two. The [[VAB]] workspace in general is vertically oriented, like a [[rocket]], as is it axis of symmetry when placing or moving parts. The SPH is horizontal in both regards, like a [[plane]] or [[rover]]. Also, the symmetry mode by default in the [[VAB]] is [[w:Radial_symmetry|radial]]; the SPH's default is [[w:Bilateral_symmetry|mirrored/bilateral symmetry]]. Since {{Version|0.90.0}} this can be toggled. In radial mode, parts can be placed singly or with two-, three-, four-, six- or eight-fold symmetry. Finally, craft launched from the [[VAB]] will start from the [[Launch Pad]] while the SPH launches from the [[Runway]].
 +
 
 +
Like all installations, the Vehicle Assembly Building is upgradeable in [[Career|Career mode]]. The maximum number of [[part]]s used for building a craft and the available range of [[action group]]s increases with the upgrade level of the building. The first level allows only 30 [[part]]s, and no [[action group]]s, the second level 255 [[part]]s, and only the basic [[action group]]s (no custom groups), and the fully upgraded building has no limits on either. The state of development of the [[Launch Pad]] also limits the size of the buildable [[craft]].

[[File:Editor GUI_00.jpg|thumb|right|Editor view within the workshops]]
 +
Since {{version|0.90.0}}, the editor interface for the [[Vehicle Assembly Building]] and the [[Spaceplane Hangar]] is the same. The only functional exceptions are the orientation of the axis of symmetry (vertical or horizontal, respectively) and the default symmetry mode (radial or mirrored). The symmetry mode can be toggled by pressing the {{key press|R}} button.
 +
 +
The graphical interface provides clickable icons for almost all actions. There are a few [[key bindings#VAB|key combinations]] without icons. The {{Key press|Control}}+{{Key press|Z}} key combination undoes the last action, and {{Key press|Control}}+{{Key press|Y}} redoes it. Also, holding down the {{Key press|[[key bindings#Modifier key|Mod]]}}, when left-clicking on a part, copies a segment of the craft consisting of the part and all its children, rather than grabbing it to be moved.

The Vehicle Assembly Building is structured around an approximately 100&nbsp;m tall assembly bay tower (108&nbsp;m including helipad) located at the center of [[KSC]]. A wing extends south from the assembly bay tower, itself taller than most buildings at [[KSC]] and structured in three tiers. A smaller, lower wing extends a short distance on the north side. On the roof, there are 2 helipads between the skylights. There are no helicopters in the game{{check version||0.90}}, but the helipads provide a suitable landing target for [[Craft#VTOL|VTOL]] vehicles.

Closed at all other times, during craft assembly the east door is visibly open (giving 50&nbsp;m clearance) as though ready for the craft to be rolled out. However, craft appear directly on the Launch Pad and the door is never seen in motion. The view outside is always lit as midday regardless of time in-game.

The Vehicle Assembly Building, commonly called the VAB (sometimes wrongly "Vertical Assembly Building"), is one of the two craft construction facilities at Kerbal Space Center. It is quite obviously inspired by NASA's real world Vehicle Assembly Building.

It is the KSC's tallest and single largest building, and situated at the heart of the complex. In Kerbal Space Program game development history, it can also be considered the oldest.

Usage

Like its counterpart the Spaceplane Hangar (SPH), the Vehicle Assembly Building is for craft construction. The parts list is the same in both facilities. Also, while it keeps its own list of saved craft files and subassemblies of parts, these can all be cross-loaded between the VAB and SPH.

There are essential differences between the two. The VAB workspace in general is vertically oriented, like a rocket, as is it axis of symmetry when placing or moving parts. The SPH is horizontal in both regards, like a plane or rover. Also, the symmetry mode by default in the VAB is radial; the SPH's default is mirrored/bilateral symmetry. Since version 0.90.0 this can be toggled. In radial mode, parts can be placed singly or with two-, three-, four-, six- or eight-fold symmetry. Finally, craft launched from the VAB will start from the Launch Pad while the SPH launches from the Runway.

Like all installations, the Vehicle Assembly Building is upgradeable in Career mode. The maximum number of parts used for building a craft and the available range of action groups increases with the upgrade level of the building. The first level allows only 30 parts, and no action groups, the second level 255 parts, and only the basic action groups (no custom groups), and the fully upgraded building has no limits on either. The state of development of the Launch Pad also limits the size of the buildable craft.

Interface

Editor view within the workshops

Since version 0.90.0, the editor interface for the Vehicle Assembly Building and the Spaceplane Hangar is the same. The only functional exceptions are the orientation of the axis of symmetry (vertical or horizontal, respectively) and the default symmetry mode (radial or mirrored). The symmetry mode can be toggled by pressing the R button.

The graphical interface provides clickable icons for almost all actions. There are a few key combinations without icons. The ^ Control+Z key combination undoes the last action, and ^ Control+Y redoes it. Also, holding down the Mod, when left-clicking on a part, copies a segment of the craft consisting of the part and all its children, rather than grabbing it to be moved.

The editor gizmos appears on the top left as the first part is paced in the workshop (they are visible only if some part placed in the workshop) and makes fine tune of the parts situation and orientation possible. They Place, Offset, Rotate and Root. The modes can be activated by clicking on them, or pressing the equivalent (1234) key.

  • Place is the default mode, for placing new and already placed parts.
  • Offset makes the fine tune of the location of the placed parts possible. Pressing (left)-⇧ Shift makes this tuning work with even finer steps.

Appearance

The Vehicle Assembly Building is structured around an approximately 100 m tall assembly bay tower (108 m including helipad) located at the center of KSC. A wing extends south from the assembly bay tower, itself taller than most buildings at KSC and structured in three tiers. A smaller, lower wing extends a short distance on the north side. On the roof, there are 2 helipads between the skylights. There are no helicopters in the game[outdated], but the helipads provide a suitable landing target for VTOL vehicles.

On the east face of the assembly bay tower is an 8-leaf vertical lift door[1] approximately 93 m tall. Closed at all other times, during craft assembly the east door is visibly open (giving 50 m clearance) as though ready for the craft to be rolled out. However, craft appear directly on the Launch Pad and the door is never seen in motion. The view outside is always lit as midday regardless of time in-game. Additionally, on the north, west, and south faces of the VAB are large, yellow, swinging doors which appear to be auxiliary entrances.

Kerbal scientists and workers roam the floor while a gauntlet of ground crew remain stationed at the main east door. Utility vehicles drive in and out and onto cargo lifts set in the north and south interior framework of the VAB. Occasionally, the utility vehicles will drive through one another, or through Kerbals on the floor, all without any effect on each other. None of this activity interacts with the build process, though scientists appear to examine the craft and workers hammer, drill, tighten, and wrench thin air.

Just to the northwest of the VAB is the retirement monument to the old Mk1 Pod used in the earliest versions of KSP.

Spoiler: Additional things to discover.
Beginning at the southeast corner of the assembly bay, a series of climbable stairs and ladders lead to the roof of the VAB. However, surmounting the ladders onto the helipad deck is very difficult.
Spoiler: Glitch
If a Kerbal jumps off of the VAB roof, they may survive, but might temporarily glitch on landing, with the arms shooting outward and becoming the "thing" for a few seconds. It is similar to the effects experienced when falling into Jool.

Levels

Biomes

  • Level 1: the VAB hex is available as an area biome, and the VAB Main Building is available as a structure biome.
  • Level 2: the VAB South Complex is added as a structure biome.
  • Level 3: the VAB South Complex is removed, and the VAB Tanks, Round Tank, and Pod Memorial are added as structure biomes.

Notes: structure biomes must be in contact with a craft to be accessed. The fact that the South Complex disappears when the VAB is fully upgraded may mean that you want to delay the upgrade until all your science instruments and/or the Mobile Processing Lab MPL-LG-2 are available. The total science that may be missed amounts to 55.5 points on 100% science rewards (Normal difficulty).
