head s . ▁ ▁This ▁proposal , ▁for ▁the ▁first ▁time , ▁made ▁a ▁solid ▁argument ▁for ▁AB M ▁deployment ▁as ▁a ▁counter force ▁weapon . ▁Pre viously ▁each ▁AB M ▁required ▁a ▁corresponding ▁war head ▁to ▁offset ▁it , ▁but ▁with ▁Lo AD S ▁and ▁M PS , ▁a ▁single ▁AB M ▁required ▁multiple ▁war head s ▁to ▁offset ▁it . ▁The ▁same ▁end ▁could ▁be ▁achieved ▁by ▁simply ▁building ▁more ▁sh el ters ▁as ▁well , ▁but ▁the ▁size ▁of ▁the ▁proposed ▁M PS ▁network ▁already ▁took ▁up ▁large ▁port ions ▁of ▁Nev ada ▁and ▁Ut ah , ▁and ▁adding ▁more ▁would ▁not ▁be ▁easy . ▁Even ▁a ▁high ▁unit ▁price , ▁Lo AD S ▁would ▁still ▁be ▁less ▁expensive ▁than ▁building ▁double ▁the ▁number ▁of ▁sh el ters . ▁Additionally , ▁as ▁each ▁set ▁of ▁M PS ▁sh el ters , ▁or ▁cells , ▁would ▁have ▁only ▁a ▁single ▁Lo AD S , ▁the ▁problems ▁with ▁nuclear ▁black out ▁causing ▁problems ▁for ▁follow - up ▁sh ots ▁was ▁not ▁an ▁issue , ▁a ▁problem ▁that ▁had ▁never ▁been ▁solved ▁in ▁Saf egu ard - like ▁solutions . ▁ ▁However , ▁there ▁was ▁a ▁concern ▁in ▁regards ▁to ▁the ▁AB M ▁treat y , ▁involving ▁its ▁use ▁of ▁rad ars . ▁In ▁order ▁to ▁ensure ▁AB M ▁systems ▁would ▁be ▁suitable ▁for ▁point ▁defense ▁only , ▁the ▁AB M ▁treat y ▁limited ▁the ▁number ▁and ▁pla cement ▁of ▁rad ar ▁systems . ▁Lo AD S ▁had ▁a ▁rad ar ▁with ▁each
