Images of the Full-Scale Model
A full-scale model of the James Webb Space Telescope was built by the prime contractor, Northrop Grumman, to provide a better understanding of the size, scale and complexity of this satellite. It was built and is supported entirely with Northrop Grumman internal funds. The model is constructed mainly of aluminum and steel, weighs 12,000 lb., and is approximately 80 feet long, 40 feet wide and 40 feet tall. The model requires 2 trucks to ship it and assembly takes a crew of 12 approximately four days. This model has travelled to a few sites since 2005. The photographs below were taken at some of its destinations.

The full-scale model was assembled on the lawn at Goddard Space Flight Center, and displayed during September 19 - 25 2005. The Webb Telescope team took a group photo with it. Seeing the people gathered next to it shows its scale nicely. Credit: NASA
