Might have had something to do with the fact that the NRL is a govermental organization, and Lockheed isn't. Based on what Aviation Leak said, the Bus 1 they originally looked at using was hardware that already existed and was government (presumably NRO) owned, not something Lockheed would have had to build. Possibly it was no longer available for some reason by the time the ICM business came up. -- MOST launched 30 June; first light, 29 July; 5arcsec | Henry Spencer pointing, 10 Sept; first science, early Oct; all well. | |

This probably gives the recon satellites the ability to change their orbital parameters on-station; both to evade interception and to make their time of passage over interesting photo targets less predictable. Both the "KH-11-like" electro-optical and the Lacrosse radar imagers have been tracked fairly closely for the past 15 years or so by the amateur community. Neither kind maneuvers much after reaching the operational orbit -- the Lacrosses hardly at all. The "KH-11s" typically carry out small orbital maintenance maneuvers at intervals of months(*) plus a larger orbit raising that seems to separate major mission phases. Given warning, they could dodge a few times, but at the expense of mission capability. The classified LEO satellites that have shown significant propulsive capability are the Titan-launched NOSS-2-A objects, now known to be TLDs hosting SLDCOM and COBRA BRASS payloads, and USA 53 and USA 144. There's a fair chance that USA 53 was a stealthified KH-11, so Bus 1 is a good candidate for its propulsion package. USA 144 is a considerable puzzle, but may be a successor to USA 53. (*) The maneuver times are quite predictable, BTW. They occur on an ascending node when the perigee drops below a certain value and the argument of perigee precesses through zero. |

What's with the Russian hardware bashing this week? FGB is now 5 years
old, and seems to be doing just fine. It came in on time, under budget. What more could you possibly want? Speaking of the Russians, if it were not for them, ISS would be abandoned, if not in the ocean. "Scott Hedrick" wrote in message .. . "Pat Flannery" wrote in message ...
