Getting more life and more value for money from Tranche 1 is good for the tax-payer.
If the delay in getting Tranche 3 means that the expense of a Typhoon replacement is deferred, that's good, too.
I remain convinced that the plan to simply scrap Tranche 1 Typhoons is not financially prudent or a sensible use of taxpayers' money.
Tranche 1 contains most of the two-seaters, so should be retained to avoid the insanity of training on single-seaters at the OCU.
When Austria was going to be buying a mix of Tranche 1 and Tranche 2 jets, EF GmbH was going to upgrade the T1s to T2 standard at its own expense - the new processors and AESA ready front bulkhead thus can't be too big or expensive a job to incorporate.
And if that is not the case, then retain T1 jets purely for training, export support, and for high fatigue sorties (like Binbrook used its Lightning F.Mk 3s).
And if Greg Bagwell's estimate of the direct operating costs of Typhoon are correct, then paint nine of the single seaters red and give 'em to the Reds!
