Question over Northrop Grumman's official history of DSP

I came across reports in May of 1970 which indicate that Northrop Grumman might of launched 1st DSP satellites earlier than November 1970 that they officially claim. \ The description of a geostationary spy satellite with camera, xray and infrared sensors which does not sound anything like Vela_(satellite) (Vela 6A and 6B being last launched in April 1970) nor Missile_Defense_Alarm_System (Midas 12 launched October 1966). Any ideas if this and the earlier two experimental satellites are part of DSP development?  Petedavo talkcontributions  05:32, 15 August 2014 (UTC)

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)
 * 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)
