Tests were conducted to determine the stability of aim of the Lance missile system when launchers are emplaced on various types of ground surfaces and under various wind conditions. A simulated Lance missile, a lightweight launcher, and a self-propelled launcher (tracked vehicle) were furnished by the U. S. Army Missile Command, Redstone Arsenal, Ala. Full-scale tests of the missile and launchers were conducted with the WES wind-generating machine to determine: (a) the ability to maintain the missile's point of aim when its launcher is placed on various types of ground surfaces and exposed to various wind conditions, (b) how the point of aim deviates with time under these various soil and wind conditions, and (c) the vertical loads on the lightweight launcher's jack pads caused by the wind. In the tests it was found that the missile's maximum movements while on the lightweight launcher were 0.561 mil horizontally and 0.305 mil vertically when referenced to the ground, which indicates excessive looseness and/or flexibility in the framework of the lightweight launcher. No settlement occurred during tests on the lightweight or self-propelled launchers placed on clay soil subgrades either during tests or between test series. Based on the results of these tests, it is believed that a subgrade possessing CBR values of 2 and greater will not permit either launcher to settle to the degree that the missile's point of aim deviates beyond an acceptable limit.
