Are their weapons being thrown away or handed on to other types that are not operational/declared yet? If they are being thrown away, that involves a cost of destruction versus a benefit in training value of dropping them on a range. All they're saving is the fuel burn for 6 months. Counteract that with the pay wasted on guys who (presumably) have posting notices elsewhere in 6 months time and now have nothing to do. This is a bean counters victory and brings nothing but shame on the RAF!
