Noticed that too John, note also the light gun (25-30mm?) turret is not on the NS presentation.
Sorry to have to ask the question. How much? (Assuming a sensor and weapons fit like the P50s ie, no sonar or air search radar, Oto 76mm and .50cal secondary).
The price is going to be critical, even assuming the NS can adequately 'sell' the idea that this would be an ideal disaster relief vessel, and force multiplier in terms of training and resupply.
Also, we is two budgets away from an election. Anything that could be spent on this could just as well be spent on social welfare or other hand outs, more conventional vote getters. Additonally, theres the fact that the crusties and SF and Joe Higgins would call this this an "aircraft carrier designed to aid the repression of third world countries, steal their resources and kill their children". None of these are exactly confidence inspiring in the short term. At a guess, the NS is playing a long game, hoping for a decision early in the life of the next Govt.
