This is posted with LEUT-east's permission. I really did this one just to stretch my drawing muscles a bit... But he liked it enough that he told me to post it.
His Castlemaine is an alt-universe replacement for the Hobart class which will be coming online soon(ish). Which is based on the Navantia 101 design. One of the competitors was the Dutch LCF design.
So what if the IFA decided it didn't have the money to design and build their own class of ships, and held a competition. Just like in real life. Only this time, the winner is:
Basically a lenghtened LCF, the main differences are the 64 cell VLS, and the WR-21 gas turbines replacing the Spey engines.
Together with a redesigned gearbox the extremely efficient WR-21 gas turbines give the Castlemaine class a rather huge increase in range. The downside is a slightly lower top speed.
Apart from accomodating the extra weapons, the lengthening of the ship almost exclusively adds to the ships bunkerage and storage, to make the operational range and duration desired by the IFAS.
The only other real difference than was that the hull was partially made out of thicker gauge steel, to accomodate operations in the extreme southern parts of Australia's waters, with the shipyard preferring to use as much of the original LCF design as possible to lower design costs.
The APAR array is fitted to a Thales-Samsung I-Mast, and the SMART-L sits a few feet higher.

And now I feel bad posting it before I was really happy with it... So I redid it. Stealth edit!
