B Word
the GR1 was finished by the time Gulf War 1 came along
I don't think that your timeline is quite accurate there unless you are suggesting that the GR1 was useless rather than finished!
I was Staneval (W) at Bruggen when Saddam invaded Kuwait and was tasked by the Staish to select and train the first 12 crews who were to deploy with GR1s to Bahrain on 28 Dec 90! The GR1 and those crews did deploy and the GR1 was at the forefront of the Air Assault that commenced on 17 Jan 91! GR4 was a lot later!
