electromagnetic waves missiles

Something was fired from the distance.
The only thing in Mikoto’s mind was the nuclear warheads, so a chill ran down her spine,
but it seemed that was not what it was. The missile was too small and there were too
many of them.
“They appear to be surface-to-surface missiles used for bombings, reports Misaka. There
are thirty to forty of them.”
“Nyah ha.”
“You appear to becoming more cat-like, so how about it? asks Misaka suggesting a
course of action.”
“Of course.”
Mikoto reached for the hatch above her head.
She opened the circular hatch that was like a small manhole and raised her upper body
out.
“This is my area of expertise, so leave it to me!!”
As she yelled, sparks flew from her bangs.
She did not fire a lightning spear. She sent an enormous amount of electromagnetic
waves to the area ahead of her. She was interfering with the radar that the missiles used
to search for the enemy while heading through the air at twice the speed of sound.
The missiles immediately lost their target and dropped down in odd directions.
Numerous explosions rang out and a shockwave struck Mikoto’s cheek like a slap even
though she was not directly hit. She ignored it and stared ahead.
