Britain's Defense Ministry said Thursday it had signed a 15-year deal with arms company BAE Systems PLC to supply ammunition to British troops and modernize the country's outdated munitions factories, AP reported. BAE said it will invest 120 million pounds (US$223 million) on munitions factories, some of which use machinery that dates back to the World War II. Armed forces minister Bob Ainsworth said the contract would provide «a guaranteed U.K.-based high quality source of ammunition.»
