The Indian Navy became the first international customer for the P-8I in January 2009, when it signed a contract with Boeing for eight P-8I Poseidon aircraft for $2.17 billion. The Indian Navy began inducting those first eight Poseidon aircraft in 2013. India became the second-biggest operator of Poseidon after the U.S. The P-8 is also operated by the Royal Australian Air Force, the United Kingdom’s Royal Air Force and the Royal Norwegian Air Force. In addition to LRMR-ASW, the P-8I has been deployed to assist during disaster relief and humanitarian missions.
