About half a dozen FLETCHER's got a revised tripod foremast, as seen on USS CASSIN YOUNG, designed for the new low frequency radars which reached service in the late 1950's. (the new low frequency radars were widely installed on FRAM and new construction) I call them "Step Masts" because the platform for the new radar was lowered for the increased weight. One of the destroyers planned to get the new radar and had the "Step Foremast" installed, in the end didn't get the radar, and she carried the SPS-6C radar and antenna on the new mast.
Rick - (and not to steal Willie's thread!!) I appreciate your more comprehensive and historical comments regarding the FLETCHER class tripod mast development.

However, for interest of frequency diversity, one or of four destroyers was directed to have a lower frequency radar installed (like SC-5, SR, or newer) and didn't require a tripod foremast. When the FLETCHER's were first upgraded after recommissioning in a near WWII configuration, the tripod foremast was often installed, but older SC radars and their antenna were installed back on the tripod mast. This was because demand for SPS-6, then SPS-6C, radars and antennas exceeded production with a sudden demand for 82 FLETCHER class destroyers being added to the fleet. Eventually, most units with tripods got SPS-6C radars installed. The planned one out of four plan for a lower frequency radar on all destroyers, didn't pan out in practice, with more units getting the SPS-6C radar than was planned and development of a new radar with lower frequency AND could be installed on destroyers was protracted.
And this statement is also valid as we had several FLETCHER's in our DesDiv 212 in San Diego which fit the above criteria even into the mid-late 1960s. I think it would be quite interesting if someone were to publish an illustrated, technical book(let) on the post-war FLETCHER class DD's including plans and details for all the various weapons, equipment, and configuration differences that were incorporated into these ships.
It IS New Years Day and we do get a wish, right?????
