I see that Andrew Davies has a book coming out on the Collins Class, this will be interesting.Another problem could be that the LOTE may not be achievable in a two year time frame. A LOTE will involve replacing almost all the major systems and is far more complex than your standard two year full cycle docking. From what I read it sounds like the entire submarine will be cut open, gutted and rebuilt which I admit does sound only slightly less complex than building a new sub.
If the LOTE cannot be achieved with in two years it could be disastrous as it means a number of the Collins class could run out of life before LOTE work could commence on them.
It looks like Australia might have yet again left a decision too late and should have commenced LOTE work several years ago.
For the benefit of those who can't get through the paywall here is an abridged version.
