Panavia Tornado Combat Aircraft

- Tornado GR1
RAF IDS variants were initially designated the Tornado GR1 with later modified aircraft designated Tornado GR1A, Tornado GR1B, Tornado GR4 and Tornado GR4A. The first of 228 GR1s was delivered on 5 June 1979, and the type entered service in the early 1980s. A total of 142 aircraft were upgraded to GR4 standard from 1997 to 2003.
- Tornado GR1B
The Tornado GR1B was a specialised anti-shipping variant of the GR1. A total of 26 were converted, which were based at RAF Lossiemouth, Scotland, replacing the Blackburn Buccaneer. Each aircraft was equipped to carry up to four Sea Eagle anti-ship missiles. At first the GR1B lacked the radar capability to track shipping, instead relying on the missile's seeker for target acquisition, later updates allowed target data to be fed from aircraft to missile.
