I had intended to post this here but inadvertently created it in my modeling blog. See http://tailspintopics.blogspot.com/2022/12/a-brief-history-of-usn-helicopter.html
One comment there so far from Richard "RJ" Tucker:
Wow! Does this article take me back. I was on the USS Nashville (LPD-13) in 1981 when we deployed on a mine countermeasures deployment with four RH-53Ds from HM-14, two mine-sweeping boats in the well, and an EOD det. We were with the USS Leader and USS Illusive MSOs (Mine Sweeper Ocean). Lots of NATO mine counter measures exercises in the North Atlantic and Med. Great liberty! Lightning paced ops at the mind boggling speed of 8 kts.
He provided a link to a picture of Nashville with RH-53Ds on board:
