TDRS-B/IUS-3 17071 kg (not deployed, launch failure)
DSP-16/IUS-14 17050 kg
TDRS-5/IUS-15 17044 kg
TDRS-1/IUS-1 17030 kg
TDRS-3/IUS-7 17016 kg
TDRS-6/IUS-13 17008 kg
DSCS/IUS-12 17000 kg? (estimate)
The IUS has been used on 15 Shuttle flights. The IUS itself is not
reusable, but the tilt table and airborne support equipment (ASE)
is; there have been three IUS ASEs flown. ASE-1 made only two
flights, on STS-6 and on 51-L when it was destroyed. ASE-2 made 7
flights, and ASE-3, built to replace the lost ASE-1, has made 6 flights
if as I suspect it was used on the current mission (haven't managed to
confirm this). The previous flights of ASE-3 are believed to be
STS-30 (Magellan), STS-33R, STS-43 (TDRS 5), STS-54 (TDRS 6) and STS-70
(TDRS 7).
