The RAF will soon have 24 'spare' Tornado F3s back from the Italian lease. Alternatively, there are at least that many low-houred Jag instructional airframes, each with 2,000 hours gone of their 6,500 hour lives. The latter could be Jag 97s for the cost of a major and about £500k per jet.
Either might be a come-down after an APG-66 equipped A-4M (but I doubt it) or the promise of an F-16C. But surely either would be better than nothing.
