NASA currently uses crawler-transporter 2 to transport the Space Launch System with the Orion spacecraft atop it from the Vehicle Assembly Building to Launch Pad 39B for the Artemis missions. Early in 2016, NASA finished upgrading crawler-transporter 2 (CT-2) to a "Super Crawler" for use in the Artemis program. [10]
With an estimated weight of 15,000 tons (13,600 tonnes), this machine is one of the heaviest mobile land machines ever built. One of two crawler-transporters built by Marion and used by NASA for transporting rockets. Marion designed and built the NASA Crawler-transporter used to transport both the Saturn V rocket, as well as the Space Shuttle. [8]
The Mobile Launcher Platform-1 on top of a crawler-transporter. A mobile launcher platform (MLP), also known as mobile launch platform, is a structure used to support a large multistage space vehicle which is assembled (stacked) vertically in an integration facility (e.g. the Vehicle Assembly Building) and then transported by a crawler-transporter (CT) to a launch pad.
When the stack integration was completed, the Mobile Launcher was moved atop one of two crawler-transporters, or Missile Crawler Transporter Facilities, 3–4 miles (4.8–6.4 km) to its pad at a speed of 1 mile per hour (1.6 km/h). Each crawler weighed 6,000,000 pounds (2,720 t) and was capable of keeping the space vehicle and its launcher ...
The Crawlerway was originally designed to support the weight of the Saturn V rocket and its payload, plus the Launch Umbilical Tower and mobile launcher platform, atop a crawler-transporter during the Apollo program. It was also used from 1981 to 2011 to transport the lighter Space Shuttles to their launch pads.

The Vehicle Assembly Building (originally the Vertical Assembly Building), or VAB, is a large building at NASA's Kennedy Space Center (KSC) in Florida, designed to assemble large pre-manufactured space vehicle components, such as the massive Saturn V, the Space Shuttle and the Space Launch System, and stack them vertically onto one of three mobile launcher platforms used by NASA.
A pair of Alco 251C engines is also used for powering the 6,000,000 lb (2,721,554 kg) NASA Crawler Transporter that transport rockets and their platforms from the Vehicle Assembly Building to the Launch Complex 39. Ultimately a refined and successful design, the 251 outlived Alco. For a time it was built in Canada by Montreal Locomotive Works.
