It would be interesting to know how often the -60 has been shipped by -130….
To my knowledge the mast extension was a design change that occurred in the UTTAS flyoff phase to reduce vibrations at higher airspeeds. The short nose and canted tail rotor are the primary vestiges of the transport requirement.
I’m aware of one transport via C-130, an incredibly tight fit. Since the C-130 could access smaller airfields, it was therefore thought beneficial. IMHO, a highly impractical form of transport, which in real life situations were avoided through alternative deployment options.
