- fault of the system but geography. While the machine (in this event, AEGIS could not lengthen the Captain's decision time) cannot alter distance, there are perhaps some refinements that can make the SPY1 more effective in the close-in environment. Admiral Fogarty has recommended some improvements which I would support. I would add that a means for displaying altitude information on a contact such as "ascending" or "descending" on the LSD should likewise be examined. (U) But beyond these specific fixes, I recommend that some additional human engineering be done on the display systems of AEGIS. The objective would be to better equip it for assisting with rapid decisions in a situation such as VINCENNES confronted. Secretary Carlucci and I visited the AEGIS mock-up at Wallop's Island for a briefing on AEGIS and a partial reconstruction of the Flight 655 shootdown. It seemed to our inexperienced eyes that the Commanding Officer should have some way of separating crucial information from other data. Moreover, the vital data should be displayed in some fashion on the LSD so the Commanding Officer and his main assistants do not have to shift their attention back and forth between displays.
- (U) Although the Policy decision to utilize an AEGIS cruiser in the Strait of Hormuz and Persian Gulf was not a focus of the investigation, I believe that a few comments on that policy are in order. Probably the most serious and destructive potential threat to both military and civilian shipping in the area is the Silkworm missile. There are other serious threats, of course, but they all require overt actions on the part of a belligerent's forces in international airspace or waters and are more subject to countermeasures. A Silkworm missile, once it has been properly sited and equipped, can be launched on a few minutes notice from the belligerent's landmass. Its flight time is a matter of seconds and it possesses an imposing destructive charge. It is an awesome weapon. The most capable platform in the U.S. inventory for handling this threat is the AEGIS cruiser. It makes the greatest sense to me to utilize the best available platform against the gravest threat. Accordingly, I strongly endorse the deployment of an AEGIS cruiser to the region as long as the Iranian Silkworm missile is considered a likely threat.
- (U) I recommend the Secretary of Defense refer this investigation to the Chief of Naval Operations for follow-on actions consistent with the Investigating Officer's recommendations as modified.
- (U) Subject to the foregoing, the proceedings, findings of fact, opinions and recommendations of the Investigating Officer, as modified by the previous endorsement, are approved.
