The Indian P-8I fleet is different from the P-8A Poseidons of the US Navy and that have a different name – Neptune. The original batch had Ark on the fin. The second batch had a different name but the current test aircraft I saw at Boeing Field both departing and arriving had a blank fin. I am not sure whether this is because it won’t have a unit name, whether it hasn’t been decided yet or whether it hasn’t been disclosed and will be added at a later date. It made for a slightly more boring look combined with the US registration taped over the paint scheme. I got it departing and returning so experimented with some slower shutter speeds to make things more interesting. The takeoff run was long so it must have been pretty heavy when it departed.
This P-8 is the first jet for a second batch ordered by the Indian government. I have to admit that I didn’t know that they had ordered more jets. I could tell it was different because the earlier jets had ARK written on the fin and this one has DAB. Maybe that is a squadron thing? The P-8I for the Indians has a number of changes from the USN standard of jet. It has a different radar mounted on the fuselage and also includes a MAD which was not part of the USN spec. Here are some shots of the two jets to show the differences between them.
