Abstract: Artillery weapon equilibrator assemblies comprising a plurality of coaxia aligned springs, the individual load response rate of which is programmed so that the cumulative load response rate of the plurality of springs simulates a curvilinear force supply curve corresponding substantially to the curvilinear load demand curve of the weapon's tipping parts which includes the gun tube to compensate for force load changes caused by variations in the position of the center of mass of the tipping parts at any degree of elevation throughout the full range of elevation and depression of the tipping parts.
