Major cockups with weapons systems for the Navy preceded the Seasprites, When the FFGs first arrived from the US, there was no helo in the RAN inventory to put on them (robbing the ship of a, if not the major part of its ASW capabilities). The fix the Navy put into place was classic - they flew a Kiowa out from Nowra to bung on the helideck as each new FFG steamed into Sydney Harbour and the Oz medjia and public didn't know (or care) any better.
