Rocco Swift's Assault on Impervious

Rocco Swift's assault on Impervious is a coordinated attack on a heavily defended missile cruiser in which battlefield advantage comes not from a clean strike but from repeated adaptation. Rocco and his flight clear a path through smaller ships, identify the destroyer directing the defense, and turn its drifting wreck into cover. When Impervious's point defenses and unusual railgun ammunition make a direct approach untenable, Wheeler's flight abandons its failed torpedo attack for close-range harpoons. The cruiser is ultimately split apart, but a dud salvo and the loss of Advantage keep the operation from reading as an effortless triumph.

Objective and Opening Attack

Senior Lieutenant Rocco Swift enters a battle already crowded with ships: Union designs clash with Tharcian vessels, and he experiences the action as exhilarating. His flight attacks with controlled, precise bursts rather than indiscriminate fire, crippling a frigate's point defenses. The rest of the flight joins in, and the light ship's drive flickers out. The episode establishes the immediate method of the assault: suppress the smaller ships and work through the screen toward the larger target.

That plan meets a numerical problem. Rocco's tactical display shows that for every small ship his side destroys, two more arrive. The Tharcian force has thousands of smaller vessels supplementing its screening ships, far more than the pilots had expected to cut through on their way to the major ships. The growing screen makes progress costly and threatens to keep the attackers away from their objective.

Rocco identifies a particular source of the resistance: a Tharcian destroyer coordinating Impervious's defense. His targeting computer identifies the ship as TNV Vigilance. Before Rocco's flight can get through, another destroyer swerves in front of them and fires point-defense rounds. Duncan Glenn warns Rocco to climb, a brief command that becomes a turning point in the attack's movement rather than a signal to press straight ahead.

Turning the Wreck into an Approach

Rocco answers the danger by calling for the flight to form up around him; he has an idea. The group uses the reduced mass of a dead destroyer, applying the combined thrust of nine Martians to make the wreck drift in the direction they want. As they maneuver it, their positioning appears to confuse the point-defense targeting systems. By the time TNV Vigilance recognizes what the group is doing, it is too late to prevent the maneuver.

The wreck serves as more than debris to navigate around: Rocco makes it part of the attack, using its movement and the resulting confusion to create an opening. His group wheels out from behind a dead corvette and races toward Impervious. For a moment, the cruiser seems within reach. The advance depends on coordinated positioning and a timely reading of the defenses, not simply on the raw firepower of Rocco's Panzerters.

Impervious's Defenses and the Failed Salvo

The apparent opening does not make the next phase easy. Impervious brings thick webs of point-defense fire to bear, while its lighter railgun batteries fire canister shot: clusters of golf-ball-sized metal bearings instead of the standard ultra-heavy, super-dense rounds. The cruiser fills the space around it with fast-moving pellets, creating a further danger for Panzerters caught in their path. Rocco's side cannot get close enough through this combination of defenses.

The difficulty is not only Impervious's weapons. Wheeler announces the beginning of the attack run while Rocco is evading a final flight of Panzerters launched from the escort carrier, whose pilots try to bracket him with rifle fire. Then the torpedo salvo fails: all the rounds are duds, and the flight suspects that its magazines may be bad. The failed weapons leave the pilots without the expected means to strike the ship from a safer distance. Wheeler responds by ordering a switch to harpoons, changing the attack from a torpedo run to a dangerous approach against Impervious's hull.

Harpoons and the Destruction of Impervious

Rocco skims close to the cruiser's hull as his rifle destroys point-defense cannons faster than they can acquire a lock on him. He flies corkscrews around the ship; the rest of his flight joins him, but the remaining defenses continue to fire. The maneuver suppresses some of the guns without making the hull safe to approach, so the pilots must carry the attack through to physical contact.

Each pilot draws a small rod from the hip, which extends into a thick spear tipped with superheated plasma. They land on Impervious's surface and drive the harpoons through its armor plating. The method makes the pilots' proximity to the ship essential: instead of relying on the dud torpedoes, they use the harpoons to penetrate the armor and open a way to damage the cruiser from within. Groans transmitted through the hull tell Rocco that Wheeler's flight has struck a vulnerable point.

The pilots push away from the planted harpoons, and Rocco's flight rockets after them. Explosions ripple from the front of Impervious; its drive flickers out, and the engineering section is overcome. The hull then splits in two, while superheated gas escapes in rings and the surrounding space fills with the ship's escaping atmosphere. Rocco smiles as the cruiser breaks apart. The sequence completes the assault's reversal: the ship that had kept the attackers at a distance is destroyed by a method that requires them to reach its surface.

Cost and Outcome

After the destruction, Wheeler notes that Advantage is down, though someone apparently managed to field working torpedoes. The remark places the successful harpoon attack alongside the damage and uncertainty of the wider operation. The earlier salvo was entirely defective, and the confirmation that working torpedoes were eventually used does not erase that failure; nor does the evidence specify the circumstances or fate of Advantage. The assault's outcome is therefore clear at the level of its main objective—Impervious is destroyed—but not reducible to an uncomplicated victory.

The action's structure is built around successive failed assumptions: the screening ships prove more numerous than anticipated, the coordinated destroyer blocks the route, Impervious's defenses make the approach impractical, and the torpedoes do not function. Each obstacle forces a tactical change, from using the destroyer wreck as moving cover to replacing the failed salvo with harpoons. Rocco's assault is distinguished by this progression from firepower to improvisation and finally to close engagement, with the cruiser destroyed only after the attackers adapt to the means that have failed them.
