Please forgive the embarrassingly dense question, but I am well and truly out of the Light Blue environment in the diaspora, so am not up to date with number plates etc
I'm assuming 12 are still operating GR4s out of Marham along with 9 & 31? Is this move one of the 2 extra Typhoon sqns that were announced in the SDSR that would be using early batch jets in the AD role? Or have I missed something else whilst buried under staff work and spreadsheets?
