Re my message #234 of last year.*
Vessels seen in Pearl Harbor on the morning of the 5th were as follows:
Five battleships (New Mexico, Mississippi, and probably the Idaho as well as two of the Texas class) five heavy cruisers (one of the Portland class, three of the class ----- and one of the New Orleans); nine light cruisers (five) of the Honolulu class and four of the Omaha class); 37 destroyers: five destroyer tenders: two (patrol boats?); several special service ships (of which two seemed to be submarines, but it could not be definitely determined); two heavy cruisers in (dry dock?) one vessel-either a battleship or a cruiser, is outside the harbor.
Key-shaped cranes, similar to those toward the stern of the Idaho class cruisers, are being constructed on the five light cruisers of the Honolulu class, on the extreme end of the after-deck.
It was also noted that the more modern masts have replaced the mainmasts which used to be on the four Omaha class vessels.
The vessels which were previously reported to be mine sweepers are, in reality, patrol boats, so please make corrections.

Apparently the Fleet goes to sea for a week of training and stays in Pearl Harbor one week. Every Wednesday, those at sea and those in the harbor change places. This movement was noted on last Wednesday, the 26th.
The following vessels were seen in Pearl Harbor on the 27th: 4 battleships (1 of the California class and 3 of the Maryland class); 4 heavy cruisers (all of the San Francisco class); 6 light cruisers (4 of the Honolulu class and 2 of the Omaha class); 25 destroyers of which 3 were outside of the harbor); 2 destroyer tenders; 1 troop transport; several transports; several submarines; and 2 submarine tenders.
The Yorktown was not in port. A vessel which appeared to be a heavy cruiser was anchored outside of the harbor.

1. According to normal practice, the fleet leaves Pearl Harbor, conducts maneuvers and forthwith returns.
[a] Not available.
2. Recently the fleet has not remained for a long period of time nor conducted maneuvers in the neighborhood of Lahaina Roads. Destroyers and submarines are the only vessels who ride at anchor there.
3. Battleships seldom, if ever, enter the ports of Hilo, Hanalei, or Kaneohe. Virtually no one has observed battleships in maneuver areas.
4. The manner in which the fleet moves :
Battleships exercise in groups of three or five, accompanied by lighter craft. They conduct maneuvers for roughly one week at sea, either to the south of Maui or to the southwest. Aircraft carriers maneuver by themselves, whereas sea plane tenders operate in concert with another vessel of the same class. Airplane firing and bombing practice is conducted in the neighborhood of the southern extremity of the island of Kahoolawe.

The heavy cruisers in groups of six carry on their operations over a period of two to three weeks, doubtless going to Samoa. The length of time that they remain at anchor in Pearl Harbor or tied up at docks is roughly four or five days at a stretch.
The light cruisers in groups of five spend one to two weeks in operations. It would seem that they carry on their maneuvers in the vicinity of Panama.
The submarines go out on 24-hour trips Mondays, Wednesdays, and Fridays.
The destroyers, in addition to accompanying the principal units of the fleet, carry on personnel training activities in the waters adjacent to Hawaii.

Re your #119*.
Report on ship maneuvers in Pearl Harbor:
1. The place where practice maneuvers are held is about 500 nautical miles southeast of here.
Direction based on:
(1) That direction taken when the ships start out is usually southeast by south and ships disappear beyond the horizon in that direction.
(2) Have never seen the fleet go westward or head for the "KAIUI" straits northwards.
(3) The west sea of the Hawaiian Islands has many reefs and islands and is not suitable as a ocean maneuver practice sea.
(4) Direction of practice will avoid all merchant ship routes and official travel routes.
Distance based on:
(1) Fuel is plentyfull and long distance high speed is possible.
(2) Guns can not be heard here.
(3) In one week's time, (actually the maneuvers mentioned in my message #231** were for the duration of four full days of 144 hours), a round trip to a distance of 864 nautical miles could be reached (if speed is 12 knots), or 1152 nautical miles (if speed is 16 knots), or 1440 nautical miles (if speed is 20 miles) is possible, however, figuring on 50% of the time being used for maneuver technicalities, a guess that the point at which the maneuvers are held would be a point of about 500 miles from Pearl Harbor.
2. The usual schedule for departure and return of the battleships is: leaving on Tuesday and returning on Friday, or leaving on Friday and returning on Saturday of the following week. All ships stay in port about a period of one week.

Re the last part of your #123. [a]
1. On the American Continent in October the Army began training barrage balloon troops at Camp Davis, North Carolina. Not only have they ordered four or five hundred balloons, but it is understood that they are considering the use of these balloons in the defense of Hawaii and Panama. In so far as Hawaii is concerned, though investigations have been made in the neighborhood of Pearl Harbor, they have not set up mooring equipment, nor have they selected the troops to man them. Furthermore, there is no indication that any training for the maintenance of balloons is being undertaken. At the present time there are no signs of barrage balloon equipment. In addition, it is difficult to imagine that they have actually any. However, even though they have actually made preparations, because they must control the air over the water and land runways of the airports in the vicinity of Pearl Harbor, Hickam, Ford and Ewa, [b] there are limits to the balloon defense of Pearl Harbor. I imagine that in all probability there is considerable opportunity left to take advantage for a surprise attack against these places.
2. In my opinion the battleships do not have torpedo nets. The details are not known. I will report the results of my investigation.
