The US offered to upgrade the comms & other systems a few years ago, we rejected the offer (read it a long time ago, so don't quote me on it). Unlike Stryker or delayed Apaches, this didn't gather much headlines.We don't even know if our P-8Is have finally got the full-spec secure comms, ESM and radar modes since we signed for Comcasa/Cismoa. Highly doubt it.
On a separate note, IN's Romeos are of the same spec as the USN, and we selected all the optional extras on offer. I'm reasonably sure that the upcoming SeaGuardian and SkyGuardian drones will be of the same spec as their own.
