A few Saudi Tonkas are operated at BAe Warton. They are fully marked up in UK livery and with UK serials. This one was ZK113 and one of the others is ZH917. These aircraft carry TSP on the fin and ‘Tornado Sustainment Program’ on the sides under the cockpit. The Saudi aircraft are being brought up to essentially GR.4 standard.
There is one fully marked up Royal Saudi Air Force Tornado operating from Warton. It was recently imaged at low-level in the Lake District in full RSAF livery. 6611 was the airframe number. This was apparently on its after conversion shake down flights presumably before eventually going back to Saudi Arabia.
Someone imaged 6611 back in early March on its first post upgrade flight.
