Well done, Magoo. Browsing through the posts on this thread, I agree with you.
Your questions that started this thread went to Capability, Costs and, I presume by inference, Risks associated with taking the F-111 beyond 2012. I will try to provide some answers to your questions as succinctly as I can using these three metrics, starting with Costs.
To set the scene on Costs, one should start with the overall budget (ie. the money that is available). To do this, I would like to draw upon previous posts from two threads that were pre-emptively shut down by someone (methinks this may have been gf0012-aust) before the data/information in these posts were adequately debated by the Forum Members. So here goes.
BUDGET and COSTS:
1. NACC/Air 6000 Project Budget (refer Defence Capability Plans published in 2001, 2004, 2006 and Defence Annual Reports 1999 to 2005) =
A$11,500 million to A$15,500 million (2004 dollars),
minus
2. Cost of 55 x F-22A systems @ US$116 million average unit procurement cost (Then Year 2008 UPC expressed in 2004 dollars) = US$6,380 million. At a risk hedged exchange rate of 0.7000, this equates to
A$9,115 million,
plus
3. Saving from not doing remaining F/A-18 HUG Phases, R3+ Deeper Level Maintenance, Repaint, Kapton Wiring Replacement, Fuel Tank Bladder Replacements, etc =
A$2,700 million (in 2004 dollars). Note: This figure does not include the increases made or flagged in DCP 2006-2016 nor the further cost increases in HUG Phases 2.3, 2.4 and 3.2,
plus
4. Saving in total operating and maintenance expenditure (not including 3. above) from not operating F/A-18s out to 2015+ by retiring them by 2010 =
A$4,500 million (2004 Dollars) - refer Defence Annual Reports 1999 to 2005,
minus
5. Total operating expenditure of F-111s out to 2020 (by taking the highest of the RAAF's figures provided in the Air Combat Capability Paper dated 03 June 2004 tabled to the Australian Parliament by AM Angus Houston) =
$3,500 million (2004 dollars),
Net Result = better than
A$6 Bn to A$10 Bn worth of savings in 2004 dollars.
The ‘
better than’ arises from the time value of money (TVM) baseline used to keep this presentation simple.
These savings would be more than enough to procure additional tanker, AEW&C, other ISR and Evolved F-111 capabilities, if managed correctly.
Apart from the AUPC used for the procurement of 55 Raptors, the figures are derived from Defence statutory financial statements and reports as well as statements made to the Parliament by the current CDF.
Even if one were to use the
US$153 million unit procurement cost stated in the Angus Houston ASPI Strategic Insight on the NACC Program, the spread of savings would still be significant (
A$3,100 million to A$7,100 million).
Hopefully, this will encourage some healthy, rational and, as you have asked, "mutually respectful debate" on the Budget and Cost elements of your questions and this thread as a whole.
