TLAM means dropping £1M missiles with 500Kg warheads on £20K fuel trucks - and assumes the enemy don't move them inside your planning cycle. Much cheaper to have a smart aircraft doing real-time targeting using dumb bombs - and smaller warheads where collateral damage is an issue - one of the issues driving the development of the SDB etc.
(IIRC during GWI one of our main weapons of choice ended being concrete practice bombs fitted with a LGB kit to take out targets parked next to schools/hospitals/mosques etc.)
