Atlas V - United Launch Alliance | On June 15, 2007, the engine in the Centaur upper stage of a ULA-launched Atlas V shut down early, leaving its payload – a pair of NRO L-30 ocean surveillance satellites – in a lower than intended orbit. The anomaly caused delays to forthcoming Atlas V and Delta IV launches, due to the common RL-10 upper stage engines. The fault was traced to a new type of valve being used in place of an older component which had gone out of production.
