Fortress Worlds: Entire Planets as Fortifications

❗️Sci-fi often portrays planets as minor battlefields, but a battle for a planet would require millions of troops and last for years or even decades.

💡High-tech civilizations can mobilize more troops and sustain them longer, making planet-wide conflicts more feasible.

🌌Spaceships in orbit do not necessarily have a tactical advantage over fortified planets. A million ground-based mega-cannons can pose a serious threat to the fleet.

🛡️Fortress worlds, with extensive fortifications and underground facilities, are formidable to invade and defend.

🗺️Fortification strategies can vary depending on the technological level, available resources, and strategic goals of the parties involved.

Why do sci-fi portrayals often depict planets as minor battlefields?

—Sci-fi often simplifies interplanetary warfare to focus on other elements of the story, such as character development or advanced technology.

Why would a battle for a planet require millions of troops?

—Planets are vast and complex, with large populations and extensive infrastructure. Capturing and securing a planet would require significant manpower and resources.

Are spaceships in orbit at a disadvantage when attacking a fortified planet?

—Fortified planets can have extensive defense systems, including ground-based weapons and orbital facilities. Spaceships in orbit face the challenge of penetrating these defenses.

What makes a fortress world difficult to invade?

—Fortress worlds are equipped with extensive fortifications, underground facilities, and defensive systems. Invading such a planet requires overcoming these defenses, which can be a daunting task.

How do fortification strategies vary in different scenarios?

—Fortification strategies depend on factors such as technology, available resources, and strategic goals. Different civilizations and situations may employ various approaches to fortifying their worlds.
