The U.S. F-35Cs – 5th-generation-fighter a/c – showed below are CATOBAR fighter jets. CATOBAR stands for Catapult Assisted Take Off But Arrested Recovery. It means that this variant of the F-35 JSF – Joint Strike Fighter aka Lightning II – is designed to be launched from a CV (Carrier Vessel aka aircraft carrier), and it is designed to land thanks to arrestor (or arresting) wires and hooks – Video:
