The RAN Seahawks are being upgraded to give them the same FLIR, ESM, RWR and MAWS as the Seasprite for commonality. (
Tenix Defence )
The only good thing about the seasprite being this late is that it makes the Seahawk upgrade project look good! (though has caused some problems due to Seasprite supposedly proving loads of system requirements first, but is now behind the Seahawk).
The main thing people keep going on about over here is the age of the airframes (7 built between '63 and '65, 4 between '85 and '86. 8 spent time shrink wrapped in a bone yard).
I've seen them around Nowra, but never close up, and I have to say they are bl00dy ugly, they make the upgraded Seahawk (with bolted on bits) look good.
I think they are way ahead of the Seahawk in terms of systems, the pictures I've seen show a nice looking glass cockpit. Shame they can't get them to work properly.
