The initial proposal for the system was to simply mount the towed launcher, (less its running gear) and its petrol generator set on the flat bed of the M548 carrier. When this was shown to Mr G.R. Jefferson, the GW Managing Director, he was not very impressed. Aware of the amount of money available, he required a much more extensive change. Greville Beale and Adrian Pollicutt led development of a very significant new arrangement was produced in quite a short period.
This included significant changes to the M548 vehicle to armour the vehicle, now designated RCM 748in za vključitev novega generatorja na dizelski pogon, ki uporablja motor Coventry Climax H 30 (kot se uporablja kot pomožna pogonska enota v rezervoarju Chieftain). Večina elektronske opreme v lansirniku ni bila bistveno spremenjena od tiste, ki se uporablja v vlečni različici. Vendar pa je bil izdelan popolnoma prenovljen oklepni lansirnik z možnostjo nalaganja osmih raket, ki je bil nameščen s protivibracijskimi nosilci na ravno posteljo vozila. Oklepna kabina je bila opremljena s panklimatskim ogrevanjem/hlajenjem in zaščito NBC.
