KA 25 and KA 27/28

Could have been 1999 – 2003. Sorry I can’t do any better than that.

If people have info on what avionics, weapons, etc and the relative capabilities of the Ka25 and Ka 28, that will serve my purpose. I am looking for Russian names.

For example, Ka-25PL has the I-2K/ I-2KE radar, Izumrod dipping sonar?
Ka-28 has Osminog-E radar, Ros (VGs-3??) dipping sonar. Nav suite is NKV-27 (wonder if this from the Kamov 27)?

does anyone have a detailed company brochure on the KA 27/28 from any of the Russian airshows? That might work just as well.

cheers
