===RC-135S Nancy Rae / Wanda Belle / Rivet Ball===
Rivet Ball was the predecessor program to Cobra Ball and was initiated with a single RC-135S (serial 59–1491, formerly a JKC-135A) on 31 December 1961. The aircraft first operated under the Nancy Rae project as an asset of [[Air Force Systems Command]], and later as an RC-135S reconnaissance platform with Strategic Air Command under project Wanda Belle. The name Rivet Ball was assigned in January 1967. The aircraft operated from Shemya AFB, Alaska. Along with most other RC-135 variants, the RC-135S had an elongated nose radome, housing an [[S band]] receiving antenna.<ref name="rc135dotcom"/><ref name="C-135 Variants by Jennings Heilig ">{{cite web|url=http://www.clubhyper.com/reference/c135jh_1.htm|title=C-135 Variants by Jennings Heilig (Artwork, No Scale)|website=www.clubhyper.com|access-date=2 February 2019|archive-date=3 March 2016|archive-url=https://web.archive.org/web/20160303234406/http://www.clubhyper.com/reference/c135jh_1.htm|url-status=live}}</ref>

The aircraft had ten large optically flat quartz windows for tracking cameras on the right side of the fuselage. Unlike any other RC-135S, Rivet Ball had a plexiglass dome mounted top-center on its fuselage for the Manual Tracker position. It obtained the first photographic documentation of Soviet [[Multiple Reentry vehicle]] (MRV) testing on 4 October 1968. On 13 January 1969, Rivet Ball was destroyed when it overran the runway when landing at Shemya, with no fatalities.<ref name="rc135dotcom"/><ref name="C-135 Variants by Jennings Heilig "/>
