India, US Set To Seal $4 Billion Deal for 6 More P-8I
- Talks between India and the United States began today to secure a USD 4 billion agreement for six additional P-8I long-range maritime patrol aircraft, a move that will boost the Indian Navy’s surveillance and anti-submarine warfare capabilities in the Indian Ocean.
- The delegation from the United States arrived in Delhi today and will remain till Friday to engage in talks over the six P-8I aircraft. Included in this group will be personnel from the US Department of Defence and delegates from Boeing, which manufactures the P-8I.
- The meetings are expected to clarify the final agreement terms, with technical points on both sides to be discussed in detail.
- The Indian Navy’s P-8I fleet currently numbers twelve, with the first eight joining in 2009 and four more following in 2016. The Navy’s original request was for ten more units, but approval was given for six in November 2019.
