What you’ll learn

  1. Make a moving runwayExplain how wind, people, deck layout, and blast protection prepare a launch path.The ship and its crew turn a moving deck into a controlled runway.
  2. Connect the jet to stored energyDescribe how the nose gear, shuttle, holdback, and steam connect an aircraft to stored launch energy.A precise mechanical connection lets the ship add acceleration without replacing the jet's engines.
  3. Release acceleration into flightTrace the controlled sequence from restrained engine power through acceleration, liftoff, and station reset.The launch transfers control from a held aircraft to a flying aircraft in seconds.
  4. Compare the launcher technologiesCompare steam catapults with EMALS and identify the human controls shared by both.Different energy pathways serve the same launch mission inside a larger chain of control.

Questions this course answers

Why does the carrier turn into the wind before launching a jet?

The ship's motion and the natural wind combine to move air across the wings before and during the catapult run.

Put these launch events in a sensible order.

The aircraft must be positioned and protected before power builds and the launcher releases it.

Match each part to its job.

The launch divides exhaust protection, acceleration, restraint, and airflow among distinct conditions and parts.

Why does a jet need a catapult when it already has powerful engines?

The carrier deck is much shorter than a land runway. The catapult adds acceleration so the aircraft reaches useful launch speed before the bow ends, while its engines continue to provide thrust.

What is the key difference between a steam catapult and EMALS?

Steam uses pressurized steam and pistons; EMALS uses electrical power conversion and a moving magnetic field. Both accelerate aircraft along the deck.
