 Unfortunately the procurement was " a profoundly inept piece of procurement " : Sir Peter Spencer , who as head of Defence Procurement inherited the project , said that : the " original requirement was ... actually impossible . I mean , there were 100 essential requirements . I read all of them . One of them said to give protection against any missile coming from any direction . " Spencer later commented : " it is always hard to imagine why people think you would be able cost effectively to buy a bespoke requirement for a very small production run . "
