Lockheed Terrastar

The Lockheed Terrastar was an experimental off-road vehicle built in 1967 by the Lockheed Aircraft Service Company in California. At the time, like several aircraft makers, Lockheed was branching out into off-road vehicles. The design came from the Forsyth brothers and revived older patents for clusters of "major and minor" wheels, known as Tristar wheels.

Each wheel cluster could rotate to step over obstacles, so the Terrastar could climb stairs, though it did better in mud than on rocks. It was skid-steered and reached about 55 km/h. It weighed 1,120 kg empty and 1,635 kg loaded. A PDF in the folder describes it as a marginal amphibian. The same Forsyth wheel principle was later used on the Landmaster film vehicle (see LL/landmaster).
