Mission details:

The first Delta 4H launch in Dec 2004, with a demonstration satellite, suffered from early cutoff of the Common Booster Core stages, and the SECO-1 orbit was lower than planned (the apogee was around 105 km) and two nanosatellites reentered immediately. The Delta 4H recovered and put the demonstration satellite in a near-synchronous orbit with a 10 degree inclination, running out of fuel in the process; this delayed further Delta 4H launches (until Nov 2007).
