A Delta IVM+ 4,2 launch was reported as placing the GPS II F3 satellite into the correct orbit for the US Air Force on 4 October . However, it has later been announced that the launch vehicle’s second stage RL-10 engine had a lower than expected thrust which had to be compensated during the three burn sequence. An investigation is now taking place into the cause of the launch anomaly.
