CL-84 SCS (Sea Control Ship version)
This was the planned production version being developed when the program was cancelled in the aftermath of the cancellation of the USN SCS program.
The CL-84/SCS was intended as an ASW/radar surveillance aircraft for operations from a short flight deck, like the various Spruance DDV proposals, the Sea Control Ship (see the Spanish CVS Principe de Asturias), the USN’s LPH/LHAs, or the RN’s Invincible class “ASW Through-Deck Cruisers” (as they were then called).

The CL-84 SCS was to be powered by 2 GE T64 engines, producing over 3,000 shp each (an uprated version of the same engine as the Vought/Hiller/Ryan XC-142A 4-engine tilt-wing transport). This engine also powers the CH-53A, etc.
