Actually....I was thinking more along the lines of what the difference is between the UH-60 military version and the S-70 civil version that would either allow or prevent the "UH-60" to be a contender for "company" use which I assumed to mean a civil application.
The second thought is whether Sikorsky has the ability to build a handful of S-70's at a reasonable price as the S-70 seems not to have set the world on fire as evidenced by the lack of them.
It is a heck of a good aircraft as proven by the success of the UH-60 but it seems to be a failure on the commerical market.
