The US Air Force is to continue with its two-track Evolved Expendable Launch Vehicle (EELV) programme, using Boeing Delta IV and Lockheed Martin Atlas V boosters, after rejecting the option of dropping one supplier. The cost of the EELV programme has risen from $17 billion to $32 billion and the impending maiden flight of the Delta IV Heavy from Cape Canaveral, which was to have been funded by Boeing, is now being paid for by the US Air Force to the tune of $150 million.
