 The first three 27C ships ("Hancock, Intrepid" and "Ticonderoga") had had their No 3 elevators moved from the centerline to the starboard deck edge, in a position relatively far aft.The next three ("Shangri-La, Lexington" and "Bon Homme Richard"), which underwent 27C and 125 concurrently, had the elevator relocated to a deck-edge position farther forward, and this location was used for the 27A ships as they in turn underwent SCB-125., the prototype for the SCB-27 conversion, was the final "Essex" to undergo SCB-125 conversion and as such, received further enhancements.
