Y

4. Bombardment Principles

{a) IDnphasis should oe given to all bombardment principles and doctrine contained in references.

(b) Bombardment problems can be expected to be an intensifica-' tion of those experienced in recent operations. Gun _positions,

pillbpxes and emplacements wil1 be dug in, and, in most cases, provided with overhead cover. All will be difficult to locate and will require painstaking .. work by air spotters. Carefully aimed, precise fire, using one or tvro guns will be required to secure the necessary destruction. Large calibers.. and bombing must be employed to strip camouflage, followed in quick success­ion by close spott".ng and fire for destruction.

(C) The nuinerous possible landing beaches make it difficult for the enemy. to concentrate defenses at all beaches. A more probable defense tactic will be the establishment of relatively light delayins forces in fixed defensive positions near all

'···

beaches, plus mobile reserves .stationed for qui-ck deployment. e. Bombardn:ents prior to XRAY Day should therefore avoid indica-ting our beach selections any more than is necessary in accom-plishing the necessary degree of preparation. Bo.11bardment plans should emphasize the interdiction of the measer road and rail-road net to prevent the movement of reserves,

(a) Fire Support Group Commanders may further sub-divide Fire Support Groups into Fire Support Units as dictat~d by require­ments within individpal sectors of responsibility. For this purpose, the initial assignments of specific ships to Groups and later changes ,·;ill be pr001ulgated by the Attack Force Com­mancier by Air Eailgrams or by despatch. \ihen sub--clirlding Fire Support Groups, ,and when preparing schedules, Attack Force Ccm­Jilanders should apply the following principles~

(1) Unless it is necessary ·to do othe:rw,ise, keep intact the A<lliinistrc.tive Units as far as possible.

(2) Distribute Flag Officers among units as equally as possible.

(3) Place ships which will operate in the same Fire Support ' Sector in the S<1ille Fire Support Unit.

(4) After the l<:.ncling, retain the identity o!~,the; F:l,re Sup­,.__./'•,~ port Unit .·.n<i utilize to a mMdmuLl the Fire •Stlpt:X>rt· Unit

Commanders, particularly in th" deliver:,- of .fl(i)EIP support.

(b) ·,ihen ships oi two or· more fire support .units are opera tin& together in tho same fire support sector, tho sel'lior officer· present in tho fire support units in the immediate. area concerned will regulate 2.nd coordinate their movemenj:.s. ·

(c) All combatant ships of destroyer or larger • siz(Lmaintain appropriate speeds of at least ~t,uerageway, ex~::

{d) Large gunfire ships, except when op€'rating inside the screen around the entire area of their operations, will at all times be provided vti t:1 a Imitable screen o:f' vessels wh:i.ch are not themselves delivering !ire against shore positions.

(e) Schedules of fire for su.pport of landings. should stress a progressive movement of !ires inland and to the flanks of the landing "6eaches as the assault waves land. Such fires sho•lld be scheduled for at least !our ho\U's a:f'ter the landing, -subject to modification by Shore Fire Control Parties after they ar-e- -;in position to control fires, Under no circumstances should scheduled fires cease during the critical period between the landing of the· first wave and the time when Shore Fire Control Parties reach positions from which they_can comr.~ence operations.

(f) In order to cns\U'e the mrodr.1um flexibility of Naval Gunfire ··-···&rP.[JUrt afte'r-1tr..AY Ilay, -fire·SUI:~port ships for call fires, and

the necessary spotting frcqueoccs, will nomally be assigned to the Regimental Naval Gunfire Liaison Officers, uho will then be responsible to tho RCT Conunc.nder, for allocutior; of !ires to battalions as :nay best meet the tactical requirements within his rogim...:.'1t.

{g)· Support Cl'aft available for support tasks hav.:; been listed in tho T~sk Orginization of the Fire Support Groups. Other craft havG been tcntativeiy allocate· .. to the vnrious screen A and radar picket groups. The i:J.llocution of craft to the various • tasks is ut tho discretion of-the Attack Force Commanders and

~should be carefully detailed in plans. In this corm_e_g_t,_iop, ~-~ attention is c'tiroctoci to tho requirements. for picket su)ports

and screening ils set forth in Appendix (I) to Annex (K), Screen­ing Plan. The usG oi' support craft for gunfire tusks should be exploited wherever possible. Attention is directed to the following pL'ns for em.plosment:

-from left to right, starting at the upper left quadrant.

(2) ~ihen a target is plotted on the map, its designation is dete:rmined as follows: The first four digits are those of the. 1000 yard square in which the plot falls; the fifth digit is the letter _of- the 200 yard sc, uare; end the last ciigit is thG nW!Iber of the 100 yard quadrant.

(o) Destroying enemy guns, torpedo tubes, rocket projectors, and motor 'torpedo and suicide boats is a most important duty for all fire support ships. Experience in recent operations · indicates tho probability of encountering large numbers of 11 suicidell boats and midget submarines. These craft are gen- . erally_well hidden in camouflaged caves at the foot of cliffs and .in riVer c.nd canal banks, In many instances, such boats· and craft have been kept in villages and other locations at c risiderable ·stance. from water - from which they are carried by uck the laucnhing site. Careful, continuous observa-tion, v1sual •~nd photographic, must be maintained of all likely sites as these craft must be destroyed before being given a chance to dll1llago our ships.

(p) Certain ships must always be availnble in each fire support group for· instant counter--battery duty against shore batteries which fire at OUr ships or landing craft. Such counter-battery ships should not be assigned distant missions which,may inter­fere. with their counter-battery functions. This particularly applies during the support of landings, as this time is usually fayorable for cnauy guns to open fire. iihen the exact location­ol an .active enemy gun cannot be determined, tho general vicin­ity shou;ta imtJ1odiatoly be covered by urea firo. This type of ~ounter-battep~ fire should be ~:t;'I'~ed by definite pkns in wtJj_ch Pr9-det~rmincd areas are ris13i~pd to the various :t'ire support ships available. · It must'·be emphasized: i:rt a.ll plans that the primary requirauorit for e:t'foctive cotilite:l'4>attory is

Air Spot will be available, both .from vo-vos float planes from battleships and· cruisers, and from VOF planes based on spotting CVEs. When air spot is used. to supplement the observation of a shore fire control party, ·communication will be via HF spotting frequencies as per paragraph 2 above. In .. all . such cases, the Bl!lail amount of fre­quency separation in the .overall frequency plan makes it necessary . that the plane, firirtg ahips and shore fire control party use every possible means to set transmitters exactly on the assigned spotting frequency. As the firing ship has the .best facilities to acccmplish this, it Lllist coach the shore·fhc control· party accordingly. flhen establishing ·contact with planes, ships will tune their receivers only as necessary to bring in the plane's transmitter, If the plane is only Slighly off frequency, communications may be maintained and coordinated by the plane tuning its receiver to receive. the ship and SFCP and the ship maintaining a split phone watch to rccei ve both SFCP and plane, If the planets transmitter is more than 2 .kcs off fre. ~I& it Shall not be used for spotting, but will be directed by the ship to report to the appropriate control officer on the VHF control net. If thG plane cannot correct its, frequency while :j..n :fl.ig,b.t, it will then either be assigned ar1,0ther mission, using .. )its secondary HF frequency, or directed to return to base, · ./
