PHOGruJ.! GUIDMiCE REPORT 

2 December 1949 

Jt.S mentioned in LCP 17/3 dated 10 Janue.ry 1949, the Panel and its 

Subpanels have drafted a Master Pl.nn Program for Components including all 

projects considered to be ene:itial to round out a balanced line of components with respect to both the old and newer requirements which are set 

up by operating environment conditions and equipment objectives. The plans 

ot these Subpa.'nels are combined in tha attach.ad document LCP 17/4,1. This 

document puts particular e:i;iphasis on that portion of the program that is 

not yet undertaken becume of la.ck of turns. 

P..JtT II 

l. Operational Category of Kaster .Plan 

The field cf component development u.nd ri;s~rch is now assigned category SR-6(0) in the master ,Plan tor rosearch and dev.Jl.opment. This category 

should insure its having priority 2, However, appraisal of its importance 

in this category requires that the program on compcnents be considered in 

the light 0£ the following peculiar circumstlmc~s. The operational requj.rcm~nts con:mon to ~ ot tno now weapons am. devices dem?m a practically complete line of new components. This is a major undertaking which, • 

under the most favorable conditions, would require i-ariods of timo much 

longer than those required for th..:i electronic equipment or the tactical 

devices themselves. This tl.JILG .matter requires that component devcl.oμJOOnt 

and its companion research and development in nateriel.s receive first importe.nce in category SR-6(p). 

;2. Deficioncies of Present Ccmpononts in Meeting Requirements 

The trends in. design Md Q.pplicatI.on .. or mw wee.pons, military vehicles 

end electronic gear f Ql' thefll, demand canponents meeting ~everal requir1JD1ents 

which, are. not lll3t by e.ny cxisti(lg iatamc.rd types. These are: (1) operating 

ambient temperatures over tho rang~ from -55oC (-67°F) to./- 200oC(.3920F) J 

(2) imprQved reliability and stability; (.3) l.'eduction in size and weight,

During the post-war period some prograss has boen me.de toward those

e.11 three Sarvices have not emphasized autt1c1enU.y the importance c.f developmant. and resoarch on compc.nG11ts. Tlus cooclusicn is based on observetilJfls of tl':.'1 inautficittncy of t.lnds ns well as the delay in role.:ising

in frcming tho technical objecti~es of spocitic prjjects due to the haste

uncertainties throughout ee.ch fiscal y-d8.r as tu whether tho Services will 

actuall.J' undertake projects tor which thay have &fBUliiad technical responsib111 ty., 

Tho Panel strongly recomends that the Committee on Electronics take 

appropriate steps to urge on all three Services the need' for a mCll"e 

realistic P.nd orderly approach to the matter ot providing funds for component devolopmont. The Panel appreciates that in lU'J¥ tiacal year- each

1. Ea.ch Service shculd provido tunds on a high priJrit7 basis tor

adequate fer systom requiromonts, r3.ther than t~ have systems characteristic@ 

excessively llmitod by the cheracteristics ...,£ available cumpcncmts. System 

povple will produce JXl. ttern of trends of physical }JS.rnmetors which must be 

administered tc.. by the ccmponants onginoor at least two yoots prior to the

mochenical shocks, to mma only 3. fell of the me.re stringf)nt requirements. 

Theso needs apply not only to spaciel purpc..sa electronic equipments 

but alsv to me.re 11 run-of-mine 11 designs. F~r thesa latter designs, toe, 

the development of a ae.tis!nctcrily impr~vod versic..n is largely conting~t
