...Tornado F2
Tornado F3 - great low level performance with a poor medium-high level performance for a fighter
Harrier GR5 without weapons clearances
Harrier GR5/7/9/a without a gun
Phoenix UAV - otherwise known as the "bugger off"
HERTi UAV - wasted valuable hangar/ramp space on an operational airfield over 3 months and flew about twice! (ask the Royal Artillery)
Typhoon years late and overbudget
DAS on a current aircraft that doesn't work (the only thing on it made by the company and it doesn't work!)
Hawk128 Tmk2 - with a smaller cockpit than the Tmk1 (as the human population gets larger!)
Astute late and over budget
CVF spiralling costs
