Just for perspective, here are the data for the old V2 weapon of WW2.
For EMP applications, note the altitude peak. V2 range was not
sufficient for Iran to Israel , but other launch point obviously are
available. One point is that we are not talking some terribly
sophistocated weapon system here ...
The motor typically burned for 60 seconds, pushing the rocket to around
4,400 ft/second (1341 m/sec). It rose to an altitude of 52 to 60 miles
(83 to 93 km) and had a range of 200 to 225 miles (321 to 362 km). The
V2 carried an explosive warhead (Amatol Fp60/40) weighing approximately
738 kg (1 ton) that was capable of flattening a city block.

>*** Correction to my earlier post, 4320 mph is for Reentry Vehicle (warhead) velocity. Missile speed is something more along the lines of 15,000 to 17,000 mph. As a note, surface/air burst warhead delivery from Iran to Jerusalem for a Shahab-3 is estimated to be 11 to 14 minutes, from several different sources. This is NOT a High Altitude EMP weapon.
>Again, my calc of 161 seconds was based on flight of approx 1000 mile distance (launcher to 300 mile altitude above 900 mile distant ground zero, straight line), ballparked based on report of 620 mile downrange flight in 100 seconds.

>> "Iran carried out a second flight test of the Shahab-3 as noted in a Reuters news reports, in The Washington Times, July 16, 2000, on July 15, 2000 test which achieved a velocity of 4,320 mph (1,931.04 M/sec.) with a 1 ton warhead."
>> "On July 22,1998 Iran conducted the first flight test of the Shahab-3 MRBM... 'according to' the Washington Times, on July 24, 1998, "The missile exploded 100 seconds after launch ---- after having traveled about 620 miles (997.58 km. down range)" (Altitude not given)

>>Lots of variables as to trajectory and payload weight, and I don't have the formulas close at hand, but conservativly back of the envelope...
>>Shahab could reach 300 mile altitude above Kansas City from 200 miles offshore, roughly 900 miles point to point, flight distance of roughly 950 miles ( SQR (900*900+300*300) = 948 mile ), so with acceleration of 0 mph to 4320 mph with only a 110 sec burn, and above info of 620 miles in 100 seconds * flight of 1000 miles = 161 seconds
