"The Space-Based Infrared System (Sbirs) geosynchronous (GEO) satellites
will provide a new generation of IR sensors designed to detect ballistic
missile launches—including “dim,” short-range boosts—faster than today’
s Defense Support Program (DSP) constellation.
"When Sbirs was originally conceived, the Pentagon envisioned two spaceborne
constellations to both detect and track ballistic missiles in flight. While
Sbirs—with its short- and medium-wave detectors—is designed to follow the
hot motor plume, the Sbirs Low constellation (now called the Space Tracking
and Surveillance System, or STSS) flies both an acquisition and a tracking
sensor payload." web page 3 | c**i
发帖数: 6973 | 2 (8) France agrees to supply full-spec Mistral ships - Defense Ministry. RIA
Novosti, Apr 13, 2011.

("Russian Vedomosti business daily had previously said the Mistral talks
were close to collapse since the Defense Ministry could not agree on the
complete set of ships' communications and control systems")
My comment: The empty hulk of Varyag which China bought from Ukraine is
equivalent to the Mistral shell Russia refuses to buy. On the other hand,
Russia appears to lag behind A LOT, for having to buy Mistral-class assault
ships (which some call helicopter carriers) in the first place and then
fighting claw and tooth to obtain innards of the ships--indicating Russia
has difficulty with electronics (likely avionics also, at a time when Russia
declines to sell electronics of Ka-28 and -31 to China (this fact makes
China look bad). |
