Ideally we should get a mix of choppers with the procurement being divided so we get the best of each type in the numbers required.
i.e i agree that the S-70 and the NH-90 are probably close to the best at what they do but there are a lot of other good options out there let me list a few
The Sikorsky MH-53 is probably one of the best naval/marine heavy lift chopper money can buy today, i believe we should get a few.With a capability to carry upto 55(yes you read that right) fully equipped special ops troops into enemy territory and back this helicopter and older variants have been a staple of NATO marine combat infiltration missions since Vietnam.Also as the pavelows have been retired from the United states military we should be able to get ToT pretty easily.

Also i believe we should not write the Russians off and try and take a look at the KA-60, it is a pretty interesting piece of kit.specifically i believe we should look at the KA-64 Sky HORSE.
