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. "SATELLITE U.S. PUTS EYE IN SKY OVER ASIA". The Canberra Times (ACT : 1926 - 1995). ACT: National Library of Australia. 22 June 1970. p. 6. Retrieved 15 August 2014. \ 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 ^{talk contributions} 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)
