The sinking of the USS Independence after the well-deck explosion turns a failed torpedo launch into the destruction of the ship. A weapon launched by Johanson strikes steel almost as soon as it leaves its tube; the blast that follows damages the vessel, and a second torpedo’s explosion in the well deck proves fatal. The ship’s stern plunges, water pours through breached ballast tanks, and the survivors’ view of the burning vessel gives way to its disappearance beneath the waves.

The failed first strike

The sequence begins with the loss of control aboard the submersible. A display light goes out, revealing that control has been switched to the pilot. The screen then shows four torpedoes, two slim and two larger. The change in control is a consequential break in the action: the submersible is no longer operating under the same command, and the weapons are now visible as an immediate threat.

Johanson launches a torpedo. It leaves its tube and shoots forward, but travels less than three metres before striking a steel wall and exploding. The short distance between launch and impact makes the weapon’s failure unusually abrupt: it does not reach an open target, but detonates against the ship’s own structure. The first explosion is therefore both a failed attack and the beginning of the damage that will make the next moments uncontrollable.

The well-deck explosion and the ship’s loss

The pressure wave seizes the Deepflight submersible and slams it backwards into the sluice. Water erupts as the submersible spins through it. During that violent movement, the second torpedo launches. Its explosion tears through the well deck, engulfing the Deepflight, its two passengers and its deadly cargo in a ball of flames. The blast and flying debris then extend the destruction beyond the well deck: debris pierces decks and bulkheads and perforates the ballast tanks at the stern.

The damaged stern admits a rush of seawater. Thousands of tonnes pour into the crater that had been the basin, and the stern plunges. The narrative makes the sinking a physical chain rather than a single instant: the torpedo explosion destroys the submersible and its cargo; debris breaches the ship; water enters through the damaged tanks; and the vessel descends at extraordinary speed. Once the ballast tanks are pierced, the ship’s scale offers no protection from the consequences of the blast.

Escape and the final view

Leon Anawak and Crowe have reached the top of the ramp when the explosion’s shockwave shakes the ship. It throws Anawak through the air and sends Crowe tumbling beside him. Anawak strikes the ridged steel, is hurled again by another shockwave and plunges into the water. Their escape is not a controlled departure from the ship: the same blast that destroys the well deck throws them through the vessel and into the sea.

They later get clear aboard a Zodiac inflatable boat. In high swell, Anawak first races over the waves and then slows, recognizing that they are large but not steep. He turns the boat around and looks back. The USS Independence rises from the slate-grey sea amid dark smoke; its island remains visible, while the flight deck is almost entirely submerged and only burning ruins remain above the water. The flames are still audible from a distance. The change from frantic escape to looking back gives the sinking its closing image: the ship that had filled the scene with blast, debris and water is now a smoking silhouette going down.

Consequence and significance

Together, Leon Anawak and Crowe watch the USS Independence sink. Crowe, pale and shaking, clings to Anawak’s jacket to keep weight off her injured leg. Her remark that intelligent life-forms cause trouble places the wreck in the larger conflict with the Yrr, but the scene offers no easy triumph: the ship is lost, the two survivors are injured or shaken, and the immediate result of the confrontation is devastation.

The sinking also brings together two kinds of danger. The torpedoes and the ship’s machinery make human technology part of the destructive sequence, while the final sight of the burning vessel leaves the survivors facing the living intelligence they have been trying to understand. The narrative does not turn the wreck into a tidy resolution. Instead, the ship disappears as Leon Anawak and Crowe remain on the water, alive to witness the scale of the loss and to carry the encounter beyond it.
