I think they have had varying ranges ... they just "test" them all to send a message ... on both sides ...
Well the missile tested,Agni-1 is a short range variant of the Agni IRBM which is primarily meant for CHINA.The 700km range enables massive flexibility against the Paks while also making available a tactical strike capability against Chinese airbases in Tibet&a little beyond.The standard missile meant for Pakistan before this variant came online was the Prithvi SSM which had ranges of 150&250 kms-which could cover most of areas of Pakiland but would have to deployed at vulnerable border areas&almost of no use against the Chinese.There have been persistent reports in the Indian press that India would test a variant of the Agni,which can theoritically hit Beijing(so around 3000-3500kms) this year.
