I want to know the answer to the following question:
Why do almost all carriers using conventional aircraft have arrested-recovery systems?
All the background I'm provided with is that "On the recovery side of the flight deck, the adaptation to the aircraft loadout is mirrored. Non-VTOL or conventional aircraft cannot decelerate on their own, and almost all carriers using them must have arrested-recovery systems (-BAR, e.g. CATOBAR or STOBAR) to recover their aircraft.". Is that enough to answer the question?
Answer: yes
