Two's In, your observation is correct.
Perhaps the NON SAC contributor needs to get a better source on the Housatonic:
From memory:
- The first S-70 design with a certified NAV and FMS coupled autopilot to include all approved IFR approaches was delivered to.....Gov't of Brunei.
- The first S-70 glass cockpit with all of the above plus an automated GPS/Inertial approach to hover at any global coordinate was delivered to...Gov't of Turkey.
So, some of the "trim" accessories are delivered to meet international customer requirements that may not have yet made the US DoD needs list.
Thanks,
