On the USS John C. Sten­nis, air­man Manuel San­tis hauls off a length of ar­rest­ing wire with frayed ends. Ar­rest­ing wires are re­placed be­fore they break and cause in­jury. A cross-deck pen­dant wire has a max­i­mum life of 125 “traps,” or ar­rests, while the pur­chase ca­ble lead­ing to the hy­draulic ar­rest­ing en­gine lasts up to 1,400.

An ar­rest­ing wire at­taches or is “swaged” to the pur­chase ca­ble in a loop, which is fab­ri­cated be­low deck in a dan­ger­ous pro­ce­dure of heat­ing zinc to a molten state at 1,000 de­grees. The Navy is test­ing an au­to­mated hy­draulic press to re­place the man­ual la­bor in the job.
