Open video to watch When a F-18 crashed into Sea due to Arresting cable break – 7 Injured
An Arresting gear, or arrestor gear, is a mechanical system used to rapidly decelerate an aircraft as it lands and it is most commonly used on CATOBAR and STOBAR aircraft carriers.
Similar systems are also found at land-based airfields for expeditionary or emergency use.
Typical systems consist of several steel wire ropes laid across the aircraft landing area
It is designed to be caught by an aircraft’s tailhook.
During a normal arrestment, the tailhook engages the wire and the aircraft’s kinetic energy is transferred to hydraulic damping systems attached below the carrier deck.

In addition, there are other related systems which use nets to catch aircraft wings or landing gear.
seems like these barricade and barrier systems are only used for emergency arrestments for aircraft without operable tailhooks.
Modern U.S. Navy aircraft carriers have the Mark 7 Mod 3 arresting gear installed, which have the capability of recovering a 50,000-pound aircraft at an engaging speed of 130 knots in a distance of 344 feet, in two seconds.
The system is designed to absorb the theoretical maximum energy of 47,500,000 fofoot-pounds at maximum cable run-out.
while Modern carriers typically have three or four arresting cables laid across the landing area
