Why an ASW carrier still needs fixed-wing aircraft

Would a Second World War escort carrier be more effective if converted into a helicopter carrier?

Use a mixed air group: fixed-wing aircraft for long-range patrol and a few helicopters for close ASW prosecution.

Converting an escort carrier entirely to helicopters would improve some tasks while sacrificing others. Fixed-wing aircraft provide the range needed to patrol far from the convoy and keep submarines submerged over a broad area. Helicopters or gyrocopter-like machines are better for close patrols and attacking a contact once found. A mixed group of roughly four helicopters plus twelve to sixteen conventional aircraft would cover both roles, with spare kits available to support helicopters operating from escorts.
