After a long delay, the Russian navy is now operating the Ka-31, the airborne early warning/surface search version of the Ka-27 shipborne ASW helicopter.
The nature of the upgrade to the Tu-160M has not been detailed, but the type is once again making its presence felt in the ongoing Russia-U.S. standoff.
Following the crash of the first production Su-57 in December, Russian politicians have been quick to support the program to keep export hopes on track.
