Why Delta IV heavy

I have a hard time believing this satellite is a 5,000lb class orbiter. The Delta IV heavy has the capability of putting around 20,000 lb directly in a GSO. You’d better off saving money using a Delta II. A Delta II has the capacity of putting such a light weight satellite in GSO>

I wonder if the weight given in the article is the satellite dry weight, and they want this last satellite in the series delivered into orbit will plenty of fuel on-board for station-keeping or repositioning, so it can be kept in use for a long-ish life. Perhaps it has other special life-extending (but massive) features as well? (sdsds - talk) 03:32, 10 November 2007 (UTC)[reply]

There could also be issues with the size of the satellite with regards to the available payload fairings for other available launch vehicles. -MBK₀₀₄ 17:57, 3 March 2010 (UTC)[reply]
