Does anyone know whether or not the aircraft that dropped the A-bombs on Hiroshima and Nagasaki were damaged by EMP?
The B-29 aircraft that delivered the nuclear weapons at Hiroshima and Nagasaki did not lose power due to damage to their electrical or electronic systems. This is simply because electrons (ejected from the air by gamma rays) are stopped quickly in normal air for bursts below roughly 10 km (about 6 miles), so they do not get a chance to be significantly deflected by the Earth’s magnetic field
If bombs had been within the intense nuclear radiation zone when the bombs exploded over those cities, then they would have suffered effects from the charge separation (radial) EMP
They were not. Radios and radars intact. Same is true for the planes that dropped bombs for tests.
But- these were low altitude shots. You get source region EMP (SREMP) but no HEMP, High Altitude Electromagnetic Pulse.
“e aircraft that dropped the A-bombs on Hiroshima and Nagasaki were damaged by EMP?”
I don’t think that these aircraft had any computers on board to worry about.
