This is going to be so cool. The US Navy commissioned an electromagnetic launcher for testing on the USS Gerald R. Ford aircraft carrier and the system will be much more efficient and smoother in launching planes in the future. It's the first time things have been shot off the ship without the old steam catapult system.
Magnets, man. Using this new system is better in so many ways. The great Internet resource says:
The main advantage is that this system allows for a more graded acceleration, inducing less stress on the aircraft's airframe. Other advantages include lower system weight, with a projected lower cost and decreased maintenance requirements. The design includes the ability to launch aircraft that are heavier or lighter than the conventional system can accommodate. In addition, the system requires far less fresh water, reducing the need for energy-intensive desalination.
