In the course of my research, I found a reference to 2.75 inch chaff rockets in the AH-1S manual (page 170 of PDF) from 1980

Further research found a paper on DTIC mentioning a chaff warhead as a future development of the 2.75 inch system.

And then recently I found the 1979 US Army Aviation Digest that actually has a picture of it in an article series on the modernized Cobra

I am curious if anyone else has any further information on the warhead, its designation, or why it never actually entered service.
