Navies of Chile and Ecuador were (are) using shipborne B206 Rangers with torpedos, but I'm afraid that You won't make a decent ASW platform from a helicopter this size (in a similar category, there is also a maritime version of AS-555 Fennec). And using them on a dedicated helicopter carrier is bit like putting 2-inch cannon into a M1 Abrams battle tank.
EDIT: Though I probably should note, that a B206/AS-555-sized helicopter could perhaps be still useful as a shipborne helo for escorts (more towards larger AS-555). But for a CVH I'd opt for something able to carry more electronics and armament, like SH-3, SH-60, Super Frelon etc.

Could You kindly tell me, to whom was directed this remark about imbeciles? Or, in other words, who are those imbeciles?
Once upon a time You posted this:

Would You be so kind to explain me, please, how the word "imbeciles" relates to point 11 of that post of Yours?
