About
Assemble a working launch pad. The ground is 8 m modules on one grid: clean and flame washed apron, hardstand, gravel, burnt scrub and access road, all ported on four edges, with a flame trench section, a cable trench, an elevated cable tray and two sizes of water main ported end to end so services run across the site. At the centre stand the launch mount, a railed ring deck on six columns with four hold down clamps that swing clear, the flame deflector under it, a smaller launch table for a light vehicle, the deluge head, the sound suppression main and the water tower that feeds them. Beside the pad the service gantry stacks on a 6 m pitch: a base section with a plant room, plain and crane topped tower sections, a swing platform that closes round the vehicle, a stair flight, a service lift, the crew access arm with its white room, the fuelling arm whose quick disconnect retracts before the arm swings, a strongback, a lightning mast and its catenary anchors. The vehicle is modular: a 24 m first stage, an interstage, a second stage, a two piece fairing that hinges open, a seven engine cluster, a grid fin section whose four fins deploy, a landing leg section whose four legs deploy, plus the transporter erector that raises it, a crawler transporter deck, a stage cradle and a payload container. The ground support is a propellant sphere and a horizontal tank, a vent stack, a flare stack, a chilldown skid, a helium bottle rack, a nitrogen purge cart, a ground power unit, arrestors, camera and floodlight towers, a windsock, fencing with a two leaf gate, blast fence, a debris catch net, a safety shower, blank warning boards, a firing room console and an electronics rack, a site office, a crew transfer van and a fire truck. Rigid node transform clips only, no skinning and no people. Cabling, hoses, umbilical lines, hoist ropes, catenary wires, the fence mesh, the catch net, the crawler track shoes and the windsock are modelled solid and never move, because flexible material needs a deformable mesh or a joint per element; the hydraulic rams and engine gimbals are static because a ram is a linkage, not one rigid node; and vapour, flame and deluge water are absent entirely, since fire and fluid are a shader, never geometry. Original AI assisted CC0 geometry: no launch provider, agency, contractor, vehicle, site or mission appears anywhere, no real vehicle silhouette or livery is reproduced, and every sign, plate, screen and hull marking is blank or an invented abstract block.

Pad Apron Module (Rocket Launch Pad and Gantry)
An 8 m square reinforced concrete pad apron module, 180 mm thick, with cast joint strips, a central drain channel and four bolt groups. Edge ported north, south, east and west so an apron of any size tiles out of repeats.
Scorched Apron Module (Rocket Launch Pad and Gantry)
The pad apron module in flame washed dark concrete, with soot patches where the exhaust plume has swept the slab. Same 8 m module and the same four edge ports, so it drops straight into an apron built from the clean tiles.
Hardstand Module (Rocket Launch Pad and Gantry)
An 8 m hardstand module for parking transporters, carts and skids beside the pad: a gravel bed, a laid concrete deck with joint lines and a yellow kerb down each side. Ported on all four edges to the same grid as the apron.
Flame Trench Section (Rocket Launch Pad and Gantry)
An 8 m section of flame trench: two 2.6 m concrete walls with a coping lip and a scorched lining, a sloped channel floor 3.4 m across, a drain sump and deluge nozzles along both kerbs. Ported at both ends so the trench runs as far as the pad needs.
Flame Deflector (Rocket Launch Pad and Gantry)
A steel framed double wedge deflector, 3.4 m wide and 2.8 m tall, that splits the exhaust plume down both arms of the trench. Ablative dark face, a bolted cradle underneath and a cooling water manifold along each flank.
Launch Mount with Clamps (Rocket Launch Pad and Gantry)
The launch mount: a ring deck 11.5 m across on six columns over the trench mouth, railed all round, with a yellow kick ring for the vehicle skirt and four hold down clamps on hinge posts that swing clear at release. Umbilical plate and cryogenic risers on one flank.
Launch Table (Rocket Launch Pad and Gantry)
A 7.2 m steel launch table for a small vehicle: four jack posts on pads, a bolted deck frame with an open flame hole, a railed working deck, an access stair and a blank hazard plate on the front girder.
Water Deluge Head (Rocket Launch Pad and Gantry)
A 6.7 m deluge head: a mast on a concrete footing carrying a spray ring of eight nozzle arms, with the feed pipe coming in at ground level through a valve block and a ladder up the mast. Sprays are not modelled.
Deluge Pipe Run (Rocket Launch Pad and Gantry)
An 8 m run of 600 mm deluge main on concrete saddles, with flanged ends, a standpipe tapping and an isolation valve body. Ported at both ends on the pipe centreline so a water main runs the length of the pad.
Deluge Pipe Elbow (Rocket Launch Pad and Gantry)
The deluge main turning a right angle on the same 8 m module: a north port and a west port meeting at a swept bend on its saddles, so the water main can follow the pad boundary.
Sound Suppression Pipe Run (Rocket Launch Pad and Gantry)
An 8 m length of 1.1 m sound suppression water main on concrete saddles, with seven standpipes and outlet heads along the top and a control box on the flank. Ported at both ends, so a suppression ring is built from repeats.
Cable Trench Section (Rocket Launch Pad and Gantry)
An 8 m cast cable trench with five removable lid slabs, a cable bed inside and a yellow duct run along one wall. Ported at both ends so power and signal routes run from the firing room to the pad.
Cable Tray Run (Rocket Launch Pad and Gantry)
An 8 m elevated cable tray on two stanchions, 1.5 m to the deck, carrying three bundles in a ladder tray with side rails. Ported at both ends at tray height so a tray route crosses a pad without blocking it.
Blast Fence Panel (Rocket Launch Pad and Gantry)
A 4.4 m blast fence panel, 3.7 m tall: a braced steel frame on two ballast pads carrying a deflection plate with vertical stiffeners and a yellow cap rail. Ported left and right so a blast wall runs as far as the pad needs.
Safety Shower and Eyewash (Rocket Launch Pad and Gantry)
An emergency safety shower and eyewash station on a concrete plinth: a 2.6 m yellow standpipe with an overhead rose and pull rod, a bowl and paddle on the stem and a blank instruction plate on the back.
Pad Water Tower (Rocket Launch Pad and Gantry)
A 22 m water tower feeding the deluge system: a lattice frame on four pads carrying an 8.4 m tank with a domed base and top, a railed catwalk, a ladder the full height and a downpipe out to the mains.
Gantry Base Section (Rocket Launch Pad and Gantry)
The bottom 6 m of the service gantry: a 5.2 m lattice bay on four concrete footings, a grated deck and handrails at the top, an access stair off the back and a plant room at the foot with a door that opens.
Gantry Tower Section (Rocket Launch Pad and Gantry)
One stackable 6 m section of service gantry: a 5.2 m square lattice bay with a grated deck, handrails on three sides and a stair flight up the back. Base and top ports on the tower axis, so a structure of any height is repeats of this piece.
Gantry Crane Section (Rocket Launch Pad and Gantry)
The gantry tower section topped with a slewing jib crane: a yellow mast on the deck, an 7.4 m boom over the pad and a hook block on a static fall. Same 6 m module and the same base and top ports as the plain section.
Gantry Swing Platform (Rocket Launch Pad and Gantry)
A gantry access platform on a hinge column: a 6.6 m grated deck whose two arms close round a 4 m vehicle, handrails on every free edge and raking struts back to the column. The deck is one node and swings clear about the column.
Gantry Stair Flight (Rocket Launch Pad and Gantry)
A standalone 6 m stair flight with stringers, footing pads, raked handrails and a grated landing at the top, for climbing between gantry decks or up onto the launch mount.
Crew Access Arm (Rocket Launch Pad and Gantry)
A 9.6 m crew access arm on a pivot column: a trussed walkway with handrails leading to a white room with a sealing collar, a window and a plant box. The whole arm is one node and swings back away from the vehicle.
Fuelling Arm (Rocket Launch Pad and Gantry)
A cryogenic fuelling arm on a pivot column: a box girder carrying two insulated transfer lines out to a quick disconnect head, with a counterweight box and a handrail. The head retracts along the arm and the arm then swings away.
Lightning Mast (Rocket Launch Pad and Gantry)
A 41 m lightning protection mast: a lattice tower on a concrete block, a narrower head section carrying the air terminal spike and the catenary arms, obstruction markers, a ladder the full height and an earth downlead box at the foot.
Catenary Wire Anchor (Rocket Launch Pad and Gantry)
A ground anchor for the lightning catenary: a ballast block with a steel frame, two sheaves, a tensioner strut and an earthing box, with a blank warning plate on the face. The wire it holds is deliberately not modelled.
Service Lift Cage (Rocket Launch Pad and Gantry)
A 12 m service lift: a lattice hoistway on a concrete pad with a caged car parked at the bottom landing, a gate that opens and the winch housing at the head. The car is modelled at rest and does not travel.
Strongback (Rocket Launch Pad and Gantry)

A two piece payload fairing, 7.4 m tall and 3.5 m across: an ogive shell with a modelled wall thickness, a longeron each side of the split line, internal stiffening hoops and a blank access panel. Each half hinges open outwards on its own node at the base of the split line.
Engine Cluster (Rocket Launch Pad and Gantry)
A seven engine cluster on its thrust structure: a ring beam on four posts with a cross brace, one centre bell and six round it on gimbal blocks, each with a turbopump box and propellant feed stubs. 3.7 m across, 3.4 m tall.
Grid Fin Set (Rocket Launch Pad and Gantry)
A 3 m forward hull section carrying four lattice grid fins stowed flat against it, each a framed grid of vanes on its own hinge fitting. The four fins deploy out to the airstream and fold back, one node each.
Landing Leg Set (Rocket Launch Pad and Gantry)
A 4.3 m aft hull section with four landing legs stowed against it: each leg is a main strut with two side stays and a round foot pad, hinged at its own base fitting, and each deploys down and out on its own node.
Transporter Erector (Rocket Launch Pad and Gantry)
A 19 m transporter erector: an eight wheel chassis with a blank cab and a hydraulic pack, carrying a trussed erector beam on a rear hinge with four vehicle cradles and their rollers. The beam raises on its own node and the wheels roll.

Debris Catch Net Frame (Rocket Launch Pad and Gantry)
A 9 m debris catch net: two braced posts on ballast pads carrying a top and mid rail with a corded net across them. The net is modelled solid and static, because a net needs a deformable mesh.
Warning Sign Board (Rocket Launch Pad and Gantry)
A 2.7 m roadside warning board on two posts and ballast pads: a large blank yellow face and a blank white panel below it, with a red marker block on the frame. Deliberately unlettered so a developer can put their own text on it.
