The CD fire routine does not allow all guns to fire at any one time. It randomly skips guns under the assumption that some can not bear. With a 40-mile hex, that is the best we can do.

Well, there you go. (You guys sure have thought of a lot of stuff) Still, a CD gun on Corregidor or Wake is more likely to engage than one on Oahu. No matter how you write the routine, it will be inaccurate for some situation. My only point - or concern - was that incorporating every CD gun that historically existed might result in the defenses being too strong, but sounds like you addressed the issue. The objective is to have a fair number of guns firing in a particular action; whether that's all of a generic small number or 30% of the historical number matters not to me - so long as the type and ratio of historical weapons are fairly represented.

I say, "what's sauce for the goose is sauce for the gander." We currently have nuclear shore bombardments, but the defending CD assets are nerfed! Remember, CD assets were concentrated to defend the vulnerable and valuable assets at specific locations on the coast, and were rarely spread around to defend everything. If the attacking fleet chose to shoot at the local bean field, that meant the CD assets had done their job.

Are AA assets handled in the same way?

Early in my career almost 40 years ago, my supervisors insisted I understand these issues. Of course, we were paid by the government to do good-quality operational analysis.

No, there are pockets of high competence in the military-industrial complex and the government. The work I was doing contributed directly to the fall of the Soviet Union.

But an army does march on its stomach, remove the food and demoralize the enemy. Perhaps the local bean field is the most valuable target after all. [;)]

Harbor Defenses of North Shore and Kaneohe Bay
 
Beginning in 1941, a considerable number of CD guns were emplaced in this area.  The initial batteries were located near Kunia (2 x 240-mm. howitzers), Kole Kole Pass (2 x 240-mm howitzers), Paalaa, (Battery Quadropod with 2 x 240-mm. howitzers) and Kunia (Battery Kalihi w/2 x 240-mm. howitzers).  In the north shore area, a battery of 4x 155-mm. GPF mobile cannon w/Panama mounts was sited nera Kahuku Ranch, along with a second, similiary equipped battery (since 1939!) sited at the Ashley Military Reservation.  Four 8-inch railway guns and a battery of four 155-mm. GPF mobile cannon (w/Panama mounts) were emplaced at Kawailoa Military Reservation beginning in 1940.  The only other batter(ies) that might be pre-Pearl Harbor vintage (reference is undated) is Battery #408 with two 8-inch long range barbette carriage (Navy) guns and four eight inch railway mount guns vic Paumalu Military Reservation.
 
After Pearl Harbor, the North Shore and Kaneohe Bay defenses were dramatically reinforced.  They added four 8-inch Railway guns at Fort Hase (Mokapu Point) in 1942, but dismantled them in 1944.  Batteries Riggs (Opaeula Military Reservation) and Battery Ricker (Brodie Camp Military Reservation), each consisting of two naval turrets mounting a pair of 8-inch guns, were also emplaced in 1942.  Then you can toss in a two gun battery of 5-incher naval pedestal mounted guns at Kahana Bay, Battery Wailia (two 3-inch pedestal mounted guns) at Wailia Point, Battery Loko with four 155-mm GPF mobile cannon vic Kualoa Ranch, and a pair of 7-inch naval casemated guns at Ahukini, Kauai Island and Monument, Kauai Island, respectively.  The list goes on with more batteries being added (to include another turret from the USS Arizona at Ulupau Head in 1945). 
 
There were a number of temporary semi-mobile 240-mm howitzer emplacements listed for Hawaii between 1937 through 1941, but I did not include them since I was not sure if they were still operational post-December 7, 1941.
 
San Diego, Los Angeles, and San Francisco (in addition to Puget Sound and Columbia River) are also surprisingly well-defended as of December 1941.  No wonder nobody tried to land on the West Coast!

If you happen to have access to it, I'd love to see the data on the 60th CA (AA), especially anything on Battery Boston...

Don,

Thanks.

Here's what I know so far. The 60th was a semi-mobile AA Regiment, probably organized generally along the lines of TO 4-111. The most recent release of this TO was August, 1941 but I can not find a copy of that. The previous release was November, 1940 but the 60th did not exactly match that TO.

As a semi-mobile AA Regiment it would have two AA Gun Battalions and one Automatic Weapons Battalion. Plus an HQ battery.

An AA Gun battalion would have three gun batteries, each of 4 3in M3 AA guns, and a searchlight battery. The November, 1940 TOE also included 4 50Cal MG in each AA Gun Battery. There is some variation in the assignment of the 50Cal MGs in the various AA Battalions and I am not sure which was used by the 60th. The basic allotment was one 50Cal to each 3inch gun, to provide defense against low level attackers. In some variations the MGs were directly assigned to the 3inch battery - either one-to-one in each firing section or as a separate platoon. In others the 50Cal MGs used to protect the 3inch AA guns were actually assigned to the Automatic Weapons Battalion. Some variations also had 50Cal to protect the searchlights, usually allocated at the ratio of one-for-one, but not always directly assigned to the searchlight battery or even the AA Gun Battalion (that is, a separate unit from the Automatic Weapons Battalion would be assigned).

The Automatic Weapons Battalion would normally be authorized a large number of 37mm AA guns, but I believe the 60th's Auto Weps Battalion had only 50Cal MG - probably four batteries of 12 guns each.

It appears that the 60th may have had a modified structure due to it's assignment. Some, but not all, of the 3inch AA Batteries appear to have had 50cal directly assigned. Battery Boston (B, 1st AA Gun Battalion) appears to have had 2 50Cal MG directly assigned, while two other 3inch batteries had four 30Cal MG and one had a mixture of 30 and 50 Cal. The remaining 3inch batteries do not appear to have had any MG assigned, although one had a battery of four 50Cal MG from the Automatic Weapons Battalion co-located. Note that there are no 30Cal MGs in the November, 1940 TO.

I have the battery dispositions at a point in time (probably just before Bataan fell) but not the official TOE. If I had to guess at an official TOE it would be:
two AA Battalions, each of 3 4-gun batteries of 3inch AA and circa 12 searchlights (no MGs)
one Auto Weps battalion with 4 12-gun batteries of 50Cal MG, mostly intended to be allocated to protect the 3inch guns and searchlights.

Battery Boston was close to Battery Wheeler (59th CA, Battery C, with two 12inch Guns in Disappearing Mounts). It was one of the batteries that was issued high altitude ammunition, and the battery to which my cousin Jimmy was assigned.

I think you'll be pleased by the improvement in Coastal Defense from Stock to AE. We put in a lot of effort trying to get the type and # of guns correct. It wasn't always easy -- many sources count "mounts" but frequently, the mounts for older WWI-era guns and mortars had been stripped of their weapons.

All the major US "Harbor Defense" units (except Manila) upgrade during the war as they did historically; generally adding a couple of 14" or 16" guns, a lot of AA, a battery or two of 90mm DP, and perhaps some 8" and 155mm GPF, while dismantling the old 10" and 12" guns/mortars and the WWI-era 3" and 6" guns. Unfortunately, the additional battleship-sniping guns generally don't arrive until 1943 or 1944 -- and if the Japanese are threatening the Pacific Coast in 1944, you are in a world of hurt! [X(]

We did review that source, thanks.

I was somewhat surprised at the variations among sources. For example, two sources indicated that there was a battery of 4" CD guns on Oahu. Others, including Berhow, do not. Fortunately, the differences tend to be "on the margins".

The question of the 4-inchers on Oahu was made moot by a technicality. Each unit has a maximim of 20 slots for devices. The Oahu "Harbor Defense" LCU would have had 21 (!) different devices if we included the 2x 4" battery. So I rolled them into the 3" guns, instead.

Thanks, this site is an old friend and one of the most detailed sources for data on the various CA Regiments there. I believe the detailed data on the 60th CA relates to a period around the end on Bataan and before the heavy shelling of Corregidor began.

This was the source of most of my data for post 1251.

[HistoryGuy]

Per Don's request about 60th CA (AA) Regt...........
 
Source: "Report of Operations of USAFFE and USFIP in the Philippine Islands 1941 - 1942 -- references to the 60th CA are included throughout this report; report located in Resources Branch (CMH), Annex VIII
 
"The Antiaircraft Defense Command, Harbor Defenses of Manila Bay"
 
"Conduct of Operations - 8 Dcember 1941 - 6 May 1942"
 
1.  In addition to performing the usual functions pertaining to antiaircraft artillery defense, the Antiaircraft Defense Command operated an air warning service for all defense and other personnel on the fortified islands of Manila Bay and naval and other vessels nearby.
 
2.  Operations of the active defense were governed by the provisions of War Department manuals; directives by the harbor defense commander; previously published annexes of the "War Plan Orange" HDM and SB; and a few "Standing Operating Procedure" directives promulagated by Antiaircraft Defense Headquarters and relating to such matters as tactical organization, the conduct of 3-inch gun fire, the conduct of automatic weapons fire, ammunition reports and supply, battle reserves of gasoline, "flash" system and certain other communications procedure(s).  Those directives are supplanted or modified to the minimum extent necessary and only as occasion demanded, by orders and/or instructions through the normal channels of command.
 
3.  The command was organized initially as follows:
 
(1) Headquarters: AA Defense Commander: CO, 60th CA (AA)
Staff: Regimental Staff, 60th CA (AA), augmented
Troops: Dets, Hq Btry, 1st and 2d Bns, 60th CA (AA)
 
(2) Mills-Hughes Gun Defense:
Commander: CO, 1st Bn, 60th CA (AA)
Troops: Fort Mills - 1st Bn, 60th CA (AA) with Btrys F & H attached
Fort Hughes - Battery I, 59th CA (HD)
Armament: 24 3-inch AA guns (mobile)
 
(3) Fort Drum Gun Defense:
Commander: CO, AA Det, Btry E, 59th CA (HD)
Troops: Det Btry E, 59th CA (HD)
Armament: 2 3-inch AA guns (1917) (fixed)
 
(4) Fort Frank Gun Defense:
Commander: CO, Btry E, 91st CA (PS)
Troops: Btry E, 91st CA (PS)
Armament: 4 3-inch AA guns (mobile)
 
(5) Bataan Gun Defense Group:
Commander: CO, 2d Bn, 60th CA (AA)
Troops: 2nd Bn, 60th CA (AA) less Btrys E, F, and H
Armament: 4 3-inch AA guns (mobile)
 
(6) Machine Gun Defense:
Commander: 3d Bn, 60th CA (AA)  (Note - 60th CA reorganized in May 1941 into three battalion regiment)
Troops: 3d Bn, 60th CA (AA)
Armament: 48 50-caliber Machine Guns (Tripod Mount)
 
(7) Searchlight Defense:
Commander: Searchlight Officer, AA Defense
Troops: Btrys A and E, 60th CA (AA)
Material: 18 60-inch Searchlight Units, 18 Sound Locators, and 4 SCR-268 RDF sets
 
(8) Antiaircraft Artillery Intelligence
Service (and Warning Service)
Troops: Dets, Regt and Bn Hqs Btrys, 60th CA (AA)
 
b.  The antiaircraft machine gun defenses of Forts Frank, Drum, and Hughes functioned under their respective Fort commanders.  From time to time, the 3-inch battery at Fort Frank was released by Harbor Defense to the Fort Commander for firing against land targets in Cavite Province.
 
c.  Beacuse of the reduced strength of the 60th CA (AA), there was not sufficient personnel to man all six of the SCR-268 sets and all of the thirty searchlights assigned to Batteries A and E.  Furthermore inasmuch as defense troops for the Cavite-Batangas headland never occupied that area, - which fell into enemy hands almost immediately after the occupation of Manila on 2 January - extention of the searchlight defense into the area was impracticable.  In the circumstances twelve of the searchlight units assigned were not needed except for replacement purposes.
 
4.  For purposes of facility, rapidity, and clarity in voice communications, batteries of the Antiaircraft Defense were assigned the following code names which, for convenience, will be used henceforth in this report in referring to particular batteries:
 
Battery A, 60th CA (AA) - Albany
Battery B, 60th CA (AA) - Boston
Battery C, 60th CA (AA) - Chicago
Battery D, 60th CA (AA) - Denver
Battery E, 60th CA (AA) - Erie
Battery F, 60th CA (AA) - Flint
Battery G, 60th CA (AA) - Globe
Battery H, 60th CA (AA) - Hartford
Battery I, 60th CA (AA) - Indiana
Battery K, 60th CA (AA) - Kingston
Battery L, 60th CA (AA) - Lansing
Battery M, 60th CA (AA) - Mobile
AA Detachment, Battery E, 50th CA (HD) - Exeter
Battery I, 59th Coast Artillery (HD) - Idaho
Battery E, 91st CA (PS) - Ermita
Battery C, 91st CA (PS) - Cebu
 
5.  On 8 December 1941, Mobile Battery was detached by higher authority and, at 7:15 PM, proceeded via the harbor boat "MAMBOUCAL," without motor transportation, to Manila where, in accordance with a previously prepared ("Sixth Sector") plan, it was disposed to provide antiaircraft machinegun protection of important localities in the Manila area, including Nichols Field.
 
Personalities (Regt Cdr, Regt XO and Bn Cdrs):
 
59th CA (AA)  Col. Paul D. Bunker, Col. Valentine P. Foster, Lt. Col. Dwight D. Edison, Lt. Col. Armand D. Hopkins, Lt. Col. Lewis S. Kirkpatrick.
 
60th CA (AA) Col. Theodore M. Chase, Lt. Col. Arnold D. Amoroso, Lt. Col. Elvin L. Barr, Lt. Col. Howard E.C. Breitung, Lt. Col. Leslie G. Ross.
 
91st Coast Artillery (PS) Col. Joseph P. Kohn, Lt. Col.  E. Carl Engelhart, Lt. Col. Floyd E. Mitchell, Lt. Col. Will K. Stennis.

Thanks Mark.

This answers most of my questions. The only one left is an official TOE one - I can not find any TOE that matches the 48-MG 3rd Battalion. Still looking...

Rest of y'all feel free to help!

Don,

The official MTOE number for all three battalions in the 60th CA (AA) was SRC 44 035C 6002 (methinks). However, based on what I saw of the process of how the regiment gained a second battalion in August 1925, what I think we have here is the old "pea and the shell game". For example:

On 24 August 1925, the 60th CA (AA) reorganized as a two-battalion regiment. The Regimental HQ and HQ Battery was activated using the 1st Battalion Hqs. The Regimental Service Company was organized as an inactive unit. The 1st Battalion Hqs was inactivated (as a billpayer for the regtl headquarters) while the 3d Platoon of Battery A was inactivated. Battery B remained active, while Battery C and Battery D were organized as inactive units The 2nd Battalion headquarters was organized an an inactive unit, Battery E as an active unit, and Batteries F, G, and H as inactive units. The Regiment's strength as of 31 December 1938 totaled 18 officers and 597 enlisted. Compare this to the authorized Battalion MTOE of 20/4/338 (not counting the regimental HHC or Service Company). From what I could tell before I got TOO confused by all the organizational orders, it seemed as if a 3d Battalion was organized (as an inactive unit) in April 1929 - but I might be wrong there. The inactive Service and Medical companies were authorized in May 1941, when the Regiment probably also had the inactive headquarters batteries and firing batteries activated. I cannot see the required equipment and personnel getting there in time to flesh out three full battalions when the 60th CA (AA) had been operating at basically 1-1/2 battalion strength for seventeen years. So, I would bet that they activated the 3d Battalion with equipment authorized "In Lieu Of" 3-inch guns, e.g. tripod mounted .50 caliber MGs. Four firing batteries x 12 MGs (three platoons of four guns each) = 48.

It appears that what I found was the first few pages of the "Moore Report" located at:
http://corregidor.org/chs_moorerpt/annexf.htm

[HistoryGuy]

AH HAH!  Now the light bulb goes off........you need the MTOE document.

The regimental MTOE (4-111) is dated 1 November 1940 with change 1 dated 5 August 1941.  The changes apply only to lines 13, 26, 27, and 44.  These essentially resulted in: Staff sergeant authorizations increasing by + 6 in the x2 gun battalions (4-115), total enlisted strength increasing by + 6 in the two gun battalions, aggregate total in the x2 gun battalions increasing by +6 and authorizations for .45 caliber pistols increasing by +6.

The semi-mobile AA regiment consisting of a regimental headquarters and band, headquarters battery (TO 4-112), x2 75-mm gun battalions (TO 4-115), 1 37-mm gun battalion (TO 4-125), attached medical and attached chaplain.

The 37-mm gun battalion is authorized 33 officers, 0 warrants, and 698 enlisted soldiers.  Major equipment end items include 32 37-mm AA guns (no .50 calibers are authorized, but coincidentally, there are 12 authorized .50 calibers in each 75-mm gun battalion - so I think they DID cross-level)  The 37-mm battalion also has six motorcycles, five 1-ton cargo trailers, seven 1/2 ton command/reconnaissance cars, six 1/2 ton pick up trucks, twenty eight 1-1/2 ton cargo trucks, twelve 2-1/2 ton cargo trucks, sixty three .45 caliber pistols, 22 Browning automatic rifles, and 637 .30 caliber rifles.

The MTOE for the battalion is also dated 1 November 1940.  It breaks down the firing batteries as: eight 37-mm. AA guns, one motorcycle with side car, one 1-ton cargo trailer, one 1/2 ton command and reconnaissance car, one 1/2-ton pick up truck, three 1-1/2 ton cargo trucks, eleven pistols, no BARs, and 143 rifles.  Battery personnel include six officers and 148 enlisted for an aggregate total of 154.  Four batteries (T/O 4-28) are authorized per battalion.   The headquarters battery has nine officers and 97 enlisted, along with an "enlisted cadre" of 67 personnel in a separate column.  There are no 37-mm guns in the HHB, but it does have two motorcycles with side cars, one 1-ton trailer, three 1/2 ton command and reconnaissance cars, two 1/2 ton pickup trucks, sixteen 1-1/2 ton cargo trucks, twelve 2-1/2 ton cargo trucks, nineteen pistols, 22 BARs, and 65 rifles.

Interesting thing is that the 37-mm. battery has a different T/O number than the MG Battery (T/O 4-27 dated 1 November 1940)

To make things more interesting, the Coast Artillery Automatic Weapons Battalion T/O 4-125 changed on 1 April 1942 to reflect eight 37-mm guns and eight .50 caliber machineguns per battery (T/O 4-127), which also now has three 1-ton trailers, two jeeps, one 3/4 ton command and reconnaissance car, one 3/4 ton weapons carrier, and three 2-1/2 ton trucks. Personnel totalled six officers and 157 enlisted armed with fiteen pistols and 148 rifles.
