d. (U) When the term "in close control" or "hooked" is used with a TN it means that the operator referred to has the following displayed on the Character Read Out (CRO) display located on his console: TN, ID, grid coordinates, course, speed, altitude, ID amplifying information, Mode I/II/III IFF received, tracking quality, bearing and range.
U
e. (C) Throughout this engagement, the large screen displays were on the following range scales: LSD1 - 8NM; LSD2 - 64NM; LSD3 - 16NM; LSD4 - 8NM. LSD3 (the CO's display) was expanded to 64NM some time before the air engagement. (IO Exhibit 209).

(a) (S) (EWS), (IDS) and (AIC-3) had an Iranian P-3 in close control. The P-3 was 62 miles west of VINCENNES, heading 085. This was the only air "assumed enemy" in the system. (IO Exhibit 91).
U
(b) (S) The E-2C (AE-602) launched in an alert status from USS FORRESTAL (CV 59), and proceeded to its assigned "EARNEST WILL" station. (IO Exhibit 250).
U
(c) (S) The SPY-1 radar initially reported the track of interest at a range of 47NM, bearing 025, and altitude of 900 feet (low elevation mode). This corresponded to a lat/long over the runway at Bandar Abbas. Initial course was 210. Mode III was 6760. (IO Exhibits 91 & 232.
U
(d) (S) The radar operators in USS VINCENNES cannot discriminate size of a contact regardless of aspect angle. (IO Exhibit 183)( p. 544).
U
(e) (S) (RSC) determined from the A-scope that TN 4131 was a single track. ( , p. 544).
U
(f) (S) (49 ADT) first took close control of the southbound track out Bandar Abbas and made an identification as "UNKNOWN-ASSUMED ENEMY" as it went "feet wet" in accordance with CTG 801.7/OPTASK AAW/002/MAY. Altitude reports to CIC consoles were derived from IFF Mode C since SPY was in low elevation mode. (IO. Exhibits 91 & 132).
U
(g) (S) (Air Detector Tracker and Track Supervisor-SIDES) recalled picking up the track on a course of 200, speed 300kts, with a Mode III - 6700 block (IO Exhibit 71).
