A few quotes -
"One time while King Citaketu was traveling in outer space on a brilliantly effulgent airplane given to him by Lord Vishnu, he saw Lord Siva..." "The arrows released by Lord Siva appeared like fiery beams emanating from the sun globe and covered the three residential airplanes, which could then no longer be seen."
Srimad Bhagavatam, Sixth Canto, Part 3
"His Saubha clung to the sky at a league's length...He threw at me rockets, missiles, spears, spikes, battle-axes, three-bladed javelins, flame-throwers, without pausing....The sky...seemed to hold a hundred suns, a hundred moons...and a hundred myriad stars. Neither day nor night could be made out, or the points of compass."
- The Mahabharata
"Gurkha, flying in his swift and powerful Vimana, hurled against the three cities of the Vrishnis and Andhakas a single projectile charged with all the power of the Universe. An incandescent column of smoke and flame as bright as the thousand suns rose in all its splendour...An iron thunderbolt, a gigantic messenger of death, which reduced to ashes the entire race of the Vrishnis and the Andhakas....The corpses were so burned as to be unrecognizable. The hair and nails fell out; pottery broke without apparent cause, and the birds turned white....After a few hours all foodstuffs were infected.... To escape from this fire, the soldiers threw themselves in streams to wash themselves and their equipment..."
- The Mahabharata
Sounds a lot like an atomic bomb to me.
"Cuka, flying on board a high-powered vimana, hurled on to the triple city a single projectile charged with all the power of the universe. An incandescent column of smoke and flame, as bright as ten thousand suns, rose in all the splendor... When the vimana returned to Earth, it looked like a splendid block of antimony resting on the ground."
