As to the USS Stark there Phalanx CIWS remained in standby mode because they were not in a combat area.
The US navy does not run there ships in condition 1 unless they are in combat waters. the danger of a weapons malfunction is too great.
Condition 1 - General Quarters (battle stations). May be modified for certain conditions, such as Condition 1-AS, in which all antisubmarine watch
stations and weapons are manned, but AAW stations may not be. Modified conditions are used to minimize crew fatigue, which can be a significant factor
over a prolonged period at battle stations. Other types of modified conditions include 1-SQ (battle stations for missile launch).
Condition 2 – A condition of modified General Quarters, generally used on large ships.
Condition 3 - A material condition of readiness commonly associated with wartime steaming where some, usually half, of the ship's weapons are kept in
a manned and ready status at all times.
Condition 4 - A material condition of readiness commonly associated with peacetime steaming. There are no weapons in a ready status.
Condition 5 – A material condition of readiness associated with peacetime inport status. Other material conditions may be set as needed, dictated by
the threat.
Most likely the ship was at condition 4 and the weapons radars would have been in standby so the ship would not been showing hostile actions.
With the Phalanx CIWS in auto mode any plane that got to close would have been fired on by the system without anyone on the ship doing anything.
This is a dangerous condition for non hostile aircraft.
The USS Stark was commissioned on 23 October 1982, CDR Terence W. Costello commanding.
I served under the first CO of the Stark CDR Terence W. Costello III on the USS Enhance during operation Endsweep in Haiphong Harbor North Vietnam.
