you need 100% reliability

and need to be able to distinguish decoys from warheads

which is very non-trivial

so its not important for missles to go fast thats ur theory ?

they go mach 3 they are gonna upgrade it to mach 5 why isnt mach 3 fast enough ?

why dont they just go mach 22 like nasa does

why would they upgrade it from mach 3 to mach 5 when they could just make it go mach 22 im not a military expert but i think the faster ur missle goes the better no ?

ballistic missiles will go mach ~20 no matter what

because they are ballistic missiles

if you want to throw something at a target halfway around the world you need to throw it at mach 20

if you have a cruise missile that's a different matter

because it's affected by the atmosphere

so it can fly with wings

but it also needs constant power to keep flying long

unless it's a hypersonic glide vehicle

the fastest missle is mach 5

what missile are you talking about?

ICBMs go far faster than mach 5

missles in general no outerspace fantasy stuff

ICBMs go mach 5

some HGVs go mach ~10 iirc

Peak speed for an ICBM is in the ballpark of 6-7km/s (any faster and the payload would go orbital), and it takes about 10 minutes to accelerate to that speed. New York to Moscow is 7500km

fastest ASMs are about mach 5

nasa goes 17500 mph

icbm not even close

nasa goes ~8km/s for orbit

so it is close

no nasa goes 17500 miles per hour

convert that to km/s

28,000 km per hour

not kilometers per hour

kilometers per second

are u saying icbms go faster

icbms go 6-7km/s as you said

orbital velocities are about 8km/s

or they would go orbital lol thats funny

7 < 8

17500 mph is 7.8232 km/s

ok

ICBMs go 6-7 km/s which is slower if you are capable of doing arithmetic
