How much would it cost to say have up to 7 radar kits able to roll-on /roll-off for about 6 aircraft which are re-lifed.
1. aircraft are already bought-need( overhauling.)
You seem to assume that the RAF has otherwise idle C130's on hand, or else the money to buy more low-time C-130's.
Also, why would a radar display on a roll-around cart be needed?
