NPAS has liquidated over a third of the air support assets, 32 down to 19 aircraft
Actually, it's only 17, as the other two are supposedly spares. However, serviceability/availability is not always as it should be:
when we visited NPAS in Wakefield in February 2017, we found that there were only eight aircraft available for operational deployment that day, and one of those had a fault that restricted it to daytime flying only.
