Checked this now.
The three ships that are initially detected and then drop off the scope are two Stereguschchy-class frigates and one Grigorovich-class frigate. All of them have very low RCS figures (orders of magnitude lower than e.g. the Chilikin-class AOR near them).
From what I see, the frigates are detected initially because the long distance of the E-3G affords a modest lookdown angle, thus relatively low clutter. As the AWACS closes the distance and maintains the altitude, the lookdown angle increases significantly, and combined with the moderate sea state this creates significant clutter, in which these low-RCS vessels manage to disappear.
So the basic physics look correct. I'm not sure if these ships should have such low RCS figures, but that's something you can discuss with the DB folks.
