ES MENUIERES, France – United Launch Alliance (ULA) will reduce its work force by 19 percent over the next few years as it weeds out unneeded overlaps in Atlas and Delta rockets and finds other efficiencies, ULA Chief Operating Officer Dan Collins said.

The head-count reduction, which follows a 16 percent staff cut over the past four years, should enable Denver-based ULA to reduce operating costs and offer reduced launch-service prices to its U.S. government customer, he said.

Collins said ULA, established in December 2006, has already surpassed its goal of cutting launch costs by 25 percent over the previous generation of rockets, and that more cost reductions are on the way. [11 Things Americans Will Be Doing in Space in 2011]
