The SOLG (Strategic Orbital Linear Gun)

Lore & Background

The SOLG was conceived during the height of the Cold War between Osea and Yuktobania, a time when both nations raced to develop weapons that could ensure mutual destruction from beyond the atmosphere. The station was built in secret, using advanced electromagnetic launch technology that could accelerate a projectile to hypersonic speeds, allowing it to strike a target within minutes of firing. Its orbital position gave it global reach, making it the ultimate expression of Yuktobanian military ambition—a sword that could fall on any enemy, anywhere, at any time. During the Circum-Pacific War, the SOLG fell under the control of a radical faction within the Yuktobanian military, led by the enigmatic General Hamilton. This group, known as the 'Grey Men,' sought to escalate the conflict into a final, apocalyptic confrontation. They used the SOLG to bombard civilian and military targets across Osea, including a devastating strike on the city of November City that left a crater where a neighborhood once stood. The weapon became a symbol of the war's senseless destruction, driving both Osean and loyalist Yuktobanian forces to unite against a common threat. The SOLG's final moments came during a desperate mission by the Wardog Squadron and their allies. With the station's guidance systems compromised and its orbit decaying—doomed to crash into the planet like a falling star—the decision was made to destroy it before it could be used again. In a climactic battle above the planet, the SOLG was shattered, its fragments burning up in the atmosphere or scattering into space. Its destruction marked the end of the war and a turning point in the history of superweapons, proving that even the most fearsome creations could be overcome by courage and cooperation.

In Their Own Story

The command deck of the SOLG was silent save for the hum of its reactors. Colonel Ivan Petrovich stared at the holographic globe below, his finger hovering over a blinking red dot—the city of Oured. 'One shot,' he whispered, 'and the war ends.' But his hand trembled. Outside the viewport, a streak of light caught his eye: a fighter, impossibly small against the void, weaving through the orbital debris. 'They're here,' his aide said. Petrovich smiled grimly. 'Then let us give them a show.' The SOLG's barrel began to rotate, tracking the distant aircraft, but before it could fire, a missile struck the station's solar array, sending sparks cascading into the black. The battle for the heavens had begun—and the final chapter of the war would be written in fire and steel.

Reader's Guide

The SOLG is one of the most iconic superweapons in the Ace Combat franchise, representing the terrifying peak of Cold War paranoia given physical form. In Ace Combat 5: The Unsung War, players face it in a multi-stage mission that demands both precision and endurance: first, you must disable its defensive systems and targeting arrays, then survive a gauntlet of enemy fighters and anti-air fire, and finally deliver the killing blow before its decaying orbit brings it crashing into the planet. The SOLG's sheer scale—a railgun barrel stretching kilometers into space—makes it a memorable setpiece, but its real threat lies in the narrative weight it carries: a weapon that turns the sky into a loaded gun, forcing friend and foe alike to question the cost of victory.

Did You Know?

• The SOLG's design was inspired by the 'Project HARP' experiments of the 1960s, which attempted to build a gun that could fire projectiles into space. Unlike HARP's ground-based cannon, the SOLG took the concept to orbit,
• In Ace Combat 5, the SOLG's orbital decay was caused by damage to its station-keeping thrusters, forcing the player to destroy it before it crashed into the planet. The resulting debris field created a spectacular—and de

• The weapon's name, 'Strategic Orbital Linear Gun,' is sometimes jokingly referred to by fans as 'So-Long' due to its role in ending the war—and the grim finality of its payload.
