Since the Seahawks are still some way off the OPV.s will have to rely on the availability of a SH2G. If the new seahawks are 4 years away or more our navy may need some special help from one of its partners.
Yeah four years seems to be the typical order/delivery timeframe for Seahawks judging by other recent international orders. But judging by the certainty of this deal for NZ (and presumably there might have been some "healthy" discussions between the two sides) it would be interesting if the US can offer to supply an airframe (or two) in say half that time frame in order to kick start the transition away from Seasprite?
However USN do not appear to be ordering MH-60R for themselves in FY25 and
FY26 to enable this, so long shot if possible, it may mean diverting an international order, which if I understand the FMS process they are designated as USN anyway initially (ok might be poor choices of wording on my behalf but others more knowledgeable might be able to spell the process out better).
Failing that surely some refurbished cabs could be utilised in the interim instead (S-70?), much like how Kaman provided interim refurbished SH-2F's to the NZDF in the late '90's until the newbuilt SH-2G(NZ)'s were ready, back in the early 2000's? At least the S-70 is cleared for most of the functionality the RNZN needs?
