re: Iran targets Diego Garcia

So it is more accurate going east because its traveling with the Earth's rotation or it travels further going west because the earth is rotating opposite of its trajectory
It's not so much accuracy as it is capability. A missile launched in an easterly direction from near the equator has the advantage of a nearly 1,000 MPH boost provided by the rotation of the earth in that direction. A missile fired in a westerly direction has to overcome the effect of the earth's easterly rotation in order to reach it's target. Of course, that's just a quick explanation of it and the velocities mentioned would be expected at or near the equator. Moving further north or south from the equator would lessen the effect though.

Bravo, I was thinking backwards.

If that’s true they are running out of options.

the 'mission' also feeds into that.
IF you are interested in putting the object into orbit, then the easterly rotation of the earth definitely assists in getting to orbital velocity.
BUT if you are interested in hitting an object to the east on the surface, the easterly launch doesn't help much unless you are going orbital along the way. Your target is moving away from you just as fast as the speed you 'gain' by launching easterly.
You can hit a target that is west of launch site by just putting the thing high in the air and then slowing down to let the target rotate below you.
Much more complicated than that simple description - all based on the performance characteristics of the hardware involved.
edit - should have said 'out of the atmosphere' instead of 'high in air'

I think so too, I'm sure we ID'ed the launch site and they knew we would.
Now where were those ICBMs launched from?

quote:I was curious as to how much easier it is to fire a rocket easterly and while significant, it's only like 5-7% of initial velocity advantage (i.e. ~15,000 mph rocket speed versus ~900 mph Earth rotation contribution depending on distance to equator.
Firing a long-range missile in an easterly direction is MUCH easier than firing it a long distance in a westerly direction due to the earth's rotation.
Helpful, yes. Game-changing? No.
EDIT: I see SwampAngel updated his response before I wrote this. A westbound missile does not fight a spinning Earth like a headwind. The missile, launch pad, and atmosphere are already moving east together so there's no "wind resistance" from Earth's rotation. It's only an energy cost to cancel the initial ~800 mph velocity gap and then add westward velocity.

Imagine you are their military and you are bleeding out in a foxhole. You happen to find a few firecrackers to throw towards your superior enemy force before you bleed out.
You know when you toss those firecrackers, you will reveal your position to the enemy which will result in a tomahawk strike on your foxhole.
What is your move, boy?

Sounds like Europe should have taken action.

Dude just wants their military to somehow defeat or score significant blows against our military, for the mere purpose of having the opportunity to gloat about a Trump “misstep.” It’s quite a few of them around here, sadly enough.

Damn, y'all are taking me back to physics. It's been too many moons to run with the big dogs. But I know at 1 click a 6.5prc will hit high going east and low going west
But I had my reasoning based on the earth moving under the projectile - completely ignoring the velocity difference.

You are so right "we" did judge them prematurely. When "we" said, oh we have been hearing for decades they are close to nuclear, oh they are not a threat, oh its just a middle east problem..........hmmmmmmm

The launch would have been detected by a satellite, right?

"an attack on one is considered an attack on all". I would think dropping a bomb on a UK base would fulfill that definition. NATO is not defined by geographic territory.
