This book on the economics of defence industry assesses a series of historical and contemporary case studies that consistently demonstrate the need for governments to recognise, and thereafter factor, the financial needs of a narrow industrial sector that is capital intensive, technologically advanced and that requires a highly skilled labour force. The chapters in this volume posit that efforts to rationalise industrial capacity and innovation to meet short-term financial efficiencies, inevitably results in limited, expensive, and long delays in increased production in times of international crisis.
