Funny Stuff

The Aster would burn up about half its fuel just getting to the point where an ASM-135 would typically launch from (~40,000ft, released from an F-15 flying almost vertically @ nearly Mach 1). And the flight till that point would be the most demanding part (from a propulsion standpoint).

The performance difference wouldn't be as impressive were the ASM-135 to be launched from ground/ship. Even if it were to retain enough power to reach about 200-odd kms (where the SM-3 blew up USA-193), which is doubtful in of itself (most likely not possible), I doubt it would retain enough energy to throw the KKV (ASM-135 would probably have used an A-bomb payload back in the day, but those aren't used nowadays) into a reliable interception path.

From what I can gather, the target satellite in the recent Indian test was travelling at a relative Mach 26+.

Well the SM-3 is only slightly heavier and has a ceiling of 550km and a range of ~900km. The intercept in 2008 was at a relative speed of 10 km/s, which is Mach 30+ if we take the speed of sound in the troposphere. The GBI intercepts are probably near Mach 40 relative speed. I would wager that if the satellite in your test was in a stable LEO orbit, the satellite alone would need to be travelling at Mach 26, although it depends what altitude you use for the speed of sound. Mach numbers don't really make sense in space.

The sat was at around 300km apparently.

The Indian ASAT (PDV Mk-2 aka XSV-1) has a claimed max altitude of over 1,000km....makes sense as the boost stage was probably taken from an existing IRBM-class Agni missile. The GBI I believe has a max altitude of twice that much.

SM-3 IIA has a ceiling of 1,500km, SM-3 IIB (680mm diameter, 6.55m length) was to have a ceiling of 2,500km. GBI (1.28m diameter, 16.6m length) could reach many thousands of km but ICBMs don't typically fly that high. Little intercept range and altitude data is available on tests of the IIA and GBI to date though but I expect the GBI mid-course intercept was at ~2,000km. The 2008 SM-3 IA intercept was at 185km.

What's the projected max altitude of GBI?

Unknown, but it's basically a similar size to a small ICBM, in fact the cancelled MGM-134 Midgetman was smaller and had a range of 11,000km. Ceiling is around 2/3rds of range typically.
 
At the airport, someone sitting next, just said to me, "Ye Lawde".

I gave her a piercing, angry stare, surprised how this young sweet Mallu girl could say something like that? I was about to blast her, but then I saw her baggage and I replayed those words in my mind, and then realized she actually had said, "Yeh allowed hai!"
