Piranha: Firing Point

The blast peeled the deck back and up. The ship just forward of the island vanished into what visually appeared to be an orange ball of intensely hot flames. The explosion age was now twenty milliseconds. Twenty thousand microseconds before, the ball of thermal energy had been contained in the body of a weapon called a Nagasaki II. Now the miraculous thundering sphere of white and orange heat blew farther aft toward the island, the forward surface of the tower above the formerly flat deck burning and disintegrating.

The ship that had been christened the USS James Webb was now only half a ship. The forward section had been either consumed by the plasma, vaporized by the plasma after effect into a gas, melted by the intense heat of the post-plasma blast, burned into flames by the continuing fireball, or sent hurtling outward and upward.

The place where there had been a ship’s bow, was now a spherical ball of high-temperature molecules of steam and condensing iron vapor and combustion products from the burned steel. The sphere was two hundred meters in diameter, and was cooling as it expanded, now turning from orange to a reddish glow, some of its periphery darkening into black smoke. The sphere was beginning to change shape, the physics of hot air rising and cool falling causing it to press upward and collapse below. As it did, the sphere began to rise from the hull waterline.

The sphere, rising above the deck, started an effect called thermal radiation. The intensely high temperatures emitted infrared energy at an enormous rate, and the traveling waves of heat melted the glass of the island that had looked down at the deck, then moved farther aft and set the bodies of forty-three crewmen on fire, burning their flesh rapidly down to the bone, igniting their lungs and cooking their brains, though not nearly as quickly as the bodies in the bow. The radiation wave reached the aircraft anchored on the aft deck and ignited them all to balls of burning carbon fiber and jet fuel.

The deck surface was now engulfed in an orange volume of names.

The radiation waves continued in a shock wave. The air surrounding the surface of the earth acted as a drum, the explosion as a drum beat. A double shock wave traveled outward from the sphere, smashing into the island, where the 117 men inside had already been busy dying from the radiation and blast effects. The wave blasted over the naming ruins of the aft deck aircraft to the two other aircraft carriers — still untouched — smashing every glass window in their islands and blowing them inward.

The shock wave weakened as it progressed outward, breaking only a third of the glass windows of the Aegis cruisers’ bridges.

The bow fireball, now a hundred milliseconds after having breached the deck, rose over the island, transforming from a sphere to a mushroom cap, leaving below it a thick stern of rising black and brown smoke and orange flames, feeding the rising orange and red ball continuing to rise into the sky, the buoyancy of the atmosphere bringing it higher. As it rose to a level five hundred meters above the deck, the ship seemed suddenly to take notice of the fact that it no longer had its front half. The ship had been going thirty-five knots, or sixty-five kilometers per hour, some eighteen meters per second. Since the explosion the hull had continued moving almost two meters, the effect of the blast slowing the ship slightly, but as the first full second moved into the second, the half hull moved another two meters forward into water that had flooded into the crater of steam.

Where there had once been a steel structure that kept seawater out, only a ragged, blasted, burning edge where the ship ended and the sea began still existed. Water flowed remorselessly into the hull, submerging ruined equipment and dead, broken bodies, invading aft where there had once been watertight bulkheads and now were ruined and ruptured pieces of steel. The ship’s forward part, at the front half of the island, listed slightly into the water as the event passed into its third second. The aft deck began to tilt upward, the still rotating screws beginning to emerge from the water.

In the fourth second the ship pitched forward as the water rushed in and filled the hulk of the vessel. The screws came completely out of the water aft, still turning, water droplets cascading everywhere. The burning airplanes on the deck — those that hadn’t been blown overboard — began to slip forward, sliding down the deckplates toward the sea. As the first flaming jet was about to hit the water, five seconds after the torpedo detonation, the second Nagasaki II torpedo detonated under the aft hull.
