More a case of the Warrior upgrade program that was WSCP started in 2011, 10 years ago. Warrior entered service in 1984, 37 years ago. In that time the Army managed to swap the radios out, swap about half the fleet sights for a Thermal system and strapped extra armour on.
The 1980s plan to stabilise the gun never happened, a paper plan to fit a new turret after Warrior 2000 did well never happened. The power pack, transmission and tracks are pretty much as designed.
37 years to effectively do f**k all.
One wonders how difficult things were to deliver. There some serious questions to be asked of bods in charge here.
