1. What Is An ICBM And What Factors Influence Its Speed?

An Intercontinental Ballistic Missile (ICBM) travels at incredibly high speeds due to several factors, including propulsion, gravity, and atmospheric conditions. Propulsion systems provide the initial thrust to escape Earth’s atmosphere.

1.1 Propulsion Systems And Stages

ICBMs use multistage rocket systems for propulsion. Each stage ignites sequentially, shedding weight and increasing velocity.

• Solid Propellant Rockets: These rockets use a solid mixture of fuel and oxidizer, offering simplicity and reliability.
• Liquid Propellant Rockets: Liquid propellant rockets provide higher specific impulse (efficiency) but are more complex to manage.
• Staging: Typically, ICBMs employ two or three stages to maximize efficiency. Each stage separates after burning its fuel, reducing the overall weight of the missile.

1.2 Gravity’s Role In ICBM Trajectory

Gravity significantly influences an ICBM’s trajectory.

• Initial Ascent: Overcoming Earth’s gravity requires immense thrust.
• Ballistic Path: Once outside the atmosphere, the missile follows a ballistic path, primarily influenced by gravity and its initial velocity.
• Re-entry: Gravity accelerates the warhead during re-entry, increasing its speed.

1.3 Atmospheric Drag And Heating

Atmospheric drag and heating are major concerns during both ascent and re-entry.

• Ascent Phase: Atmospheric drag reduces the missile’s speed and requires additional fuel to overcome.
• Re-entry Phase: As the warhead re-enters the atmosphere, it encounters extreme friction, generating intense heat. Heat shields are crucial for protecting the warhead.

1.4 Earth’s Rotation And Coriolis Effect

Earth’s rotation and the Coriolis effect also impact ICBM trajectories.
