CODAS with electric motors? That strikes me as a bit over-complex.
I think a CLAA will suit Chile's needs better than an odd helicopter hybrid, but then I've been prejudiced against helicopters in WW. Yes several nations have them now but I've never really seen a role for them so far in the sim. Once someone builds a compact but powerful enough helicopter to lug a dipping sonar and a homing torpedo then I'll be interested. As things stand currently I don't really buy them as being adequate seaplane replacements due to shorter range and vulnerability. They are fine for ship-to-shore communications and plane guards for carriers and light duties, but you'd need a hefty tandem-rotor design to get anything worthwhile and that really needs a small carrier for adequate deck space.
