The merlin was pitched to the PN back in the early 2000s... but it was declined as it was deemed too big to fit on any future PN surface combatant. The PN has selected the Z-9 for its shipbased AsHW asset so what is left is a shore based long ranged SAR/ASW helicopter. The S-70 may be an attractive option based on the T-70.. but the presence of US engines and associated headaches may push the PN towards an Italian or Chinese system. The newer Z-18 has been pitched but its too early to speculate on it. Budgets are thin and right now the PN would prefer the most effective force multiplier.
