The Threat

D(ring )orld )ar ** +ermany" ,apan and the United States %ere all trying to develop anti-ship missiles. The +ermans prod(ed several types of these%eapons and %ere the first to p(t them to operational (se. The R(hrstahl P !// 0 1Frit2-03 radio ontrolled armor-piering glide bomb is ane2ample of this early g(ided missile tehnology. *t %as developed from the !// 4g SD!// armor-piering free fall bomb" %ith added %ings and tails(rfaes and a more aerodynami nose. 5ovable fins in the tail o(ld a(se slight hanges to the bomb6s tra'etory. *t %as la(nhed from an airplane afe% miles from the target. The bombardier in the plane %athed a flare in the bomb6s tail and g(ided the 7!8/ po(nd bomb to the target %ith radiosignals. Later versions (sed %ire g(idane to avoid radio 'amming. *t had only abo(t 9/: a(ray against targets.

The fate of the USS Savannah L-!9 reveals the serio(sness of the danger toshipping from these early anti-ship missiles. ;n September " <!7" the ship%as s(pporting the =llied landing at Salerno *taly. D(ring a +erman air raid aDornier D; 9$>-9 bomber flying at ?"8// feet g(ided a Frit2-0 to stri4e theSavannah6s N(mber 7 t(rret. The bomb penetrated the armored top of the t(rretand pl(nged thro(gh three de4s to the lo%er handling room %here it e2ploded.The blast ble% a hole in the ship6s h(ll and 4illed <$ men" inl(ding everyone inthe t(rret and handling room. @ffetive damage ontrol proed(res saved the ship" b(t it %as o(t of ation for a year %hile being repaired.7 

 N(mero(s other ships %ere s(n4 by +erman glide and ro4et-po%ered bombs la(nhed from airraft d(ring the %ar" inl(ding large heavilyarmored battleships.

The US developed the S);D-5ar4 < 5od / Aat radar g(ided anti-ship bombthat (sed ative radar homing to deliver a /// po(nd %arhead. This %eapon%as (sed to destroy several ,apanese ships near the end of the %ar.

These %eapons %ere early g(ided missiles" and they posed a serio(s threat to naval and maritime shipping. Naval planners realiBed that anti-shipmissile tehnology %o(ld develop rapidly and %o(ld beome the most serio(s threat to the fleet. Some means %as needed to interept and destroymissile-arrying airraft before they ame lose eno(gh to la(nh their %eapons.

*n ,(ly <!! the Navy A(rea( of ;rdnane 1A(;rd3 began an initial analysis and eval(ation of the problem of proteting a tas4 fore from g(idedmissiles la(nhed from enemy planes beyond the range of e2isting anti-airraft g(ns and fire ontrol systems.

*n the fall of <!! A(;rd re(ested advie abo(t defensive %eapons for ships. ,ohns Hop4ins University =pplied Physis Laboratory 1=PL3 prod(ed an analysis of the problem that revealed that the missile %o(ld haveto be s(personi to be able to reah a target before it %o(ld be lose eno(gh to la(nh an anti-ship missile. =irraft" even 'ets" %ere s(bsoni at that time" and %ere too slo%. @2isting ro4ets o(ld not travel the re(ireddistanes. Ram'ets %ere tho(ght to be theoretially apable of meeting the re(irements b(t a pratial ram'et had never been tested. =PL proposed a s(personi ram'et-propelled missile %ith a range of 9/"/// yards 1miles3 that %o(ld arry a #// po(nd %arhead. *t %o(ld (se radar g(idane and some form of homing system to steer it to the target. They estimated that a prototype o(ld be b(ilt in t%o years" %ith limited (se in thelater stages of the %ar 1it %as ass(med that the %ar %o(ld last into <!# or <!$3.

)hile these dis(ssions %ere in progress the ,apanese introd(ed the 4ami4aBe in ;tober <!!. This %as another type of g(ided missile" and they a(sed great damage to the fleet" sin4ing abo(t 8/ Navy and merhantships. The damage being inflited by these %eapons gave e2tra importane to the development of an anti-airraft g(ided missile. *n Deember <!! A(;rd deided to proeed %ith development on an E(rgentE basis.!" # 

Bumblebee

*n <!/ a pro'et %as started by 5erle T(ve of the arnegie *nstit(tion to develop a radio pro2imity ETE 1variable time3 f(Be for anti-airraft shells. The gro(p %asdesignated Setion T 1T(ve6s initial3. To speed development in <!9 a ontrat %as signed %ith ,ohns Hop4ins University to organiBe the =pplied Physis Laboratory 1=PL3to p(rs(e %or4 on the f(Be. The f(Be %as in prod(tion and delivered to the fleet by the end of <!9. The first s(essf(l (se of the ne% f(Be %as in ,an(ary <!7 %hen theUSS Helena (sed it to shoot do%n ,apanese airraft.8 

=fter the T f(Be pro'et %as ompleted =PL t(rned its attentions to the development of a g(ided missile to interept airraft beyond the range of g(nfire. ;n Deember "<!!" =PL began a ne% researh ontrat %ith A(;rd to proeed %ith the development of g(ided 'et propelled missiles" and all other A(rea(s of the Navy %ere to provides(pport as needed. The entral Laboratory for Setion T %as restr(t(red as an entity diretly (nder ontrat to A(;rd" to opera te independently as the =pplied PhysisLaboratory. The p(rpose of ETas4 FE %as to prod(e a prototype intereptor missile" or prove that it o(ldn6t be done. The proposed missile %as given the ode name Torh1the ETE from Setion T3.! 

*n @arly <!8 the ode %ord EA(mblebeeE %as assigned. The name ame from a %all hanging Dr. T(ve notied in the ;ffie of Sientifi Researh and Development&

so he goes ahead and flies any%ay.

The similarity to the %or4 of Tas4 F %as noted" and the pro'et name EA(mblebeeE seemed appropriate. # 

)hen %or4 started on Tas4 F to determine if a ram'et missile %o(ld %or4 some tho(ght %as given to the name of the ne% missile. A(lfinh6s  Age of Fable desribed the demigod Talos that fle% thro(gh the air at s(hgreat speeds that he t(rned red hot" and destroyed his enemies by grabbing them and pressing them to his breast to ininerate them. The name %as adopted for the ne% missile in ,an(ary" <!?.!

 No failities e2isted in ,an(ary <!8 for testing s(personi ram'ets. =n abandoned oast +(ard Station at *sland Aeah" Ne% ,ersey" %as hastily developed into a field test site. Ay =pril the A(mblebee team %as firingtest vehiles off the Ne% ,ersey shore. = tr(4 mo(nted SR-8?! radar %as (sed to tra4 the test vehiles. Tests %ere ompliated by off shore shipping and fishing boat traffi" re(iring firing to be delayed (ntil therange %as lear.

Three large air ompressors %ere disovered at Shasta Dam" alifornia" that had been (sed to drive pne(mati hammers d(ring onstr(tion of thedam. These %ere moved to Silver Spring to generate airflo% for a ne% s(personi %ind t(nnel. Ay ,(ly <!8 e2periments %ere (nder%ay to test ram'et engine models and f(els.

=s test vehiles beame larger and fle% to greater distanes the flight program %as moved from Ne% ,ersey to a more remote area at amp Davis North arolina. =s ranges inreased f(rther the program %as moved tothe Naval ;rdnane Test Station at *nyo4ern alifornia 1hina La4e3. F(rther tests of long range interepts %ere ond(ted at )hite Sands Ne% 5e2io.

The initial goals for the A(mblebee Pro'et %ere to develop a missile that o(ld interept a target at a horiBontal range of / miles and 7/"/// feet altit(de" %ith an a(ray of 9 feet per // feet target range. = %arhead%eight of 7//-#// po(nds %as re(ired for a 4ill probability of /.7 to /.#. Po%ered flight (p to interept %as another goal. ! 

@arly efforts %ere onerned %ith st(dying the basi problems assoiated %ith the goal of prod(ing a s(personi missile. ;ne gro(p %as developing b(rner test vehiles 1AT3 to st(dy ram'et performane. = series ofinreasingly large and omple2 test vehiles %as designed and flo%n to eval(ate ram'et performane. The Ram'et History page provides a detailed history of the development of the Talos ram'et engine. >no%ledge abo(tram'ets learned in the Talos program helped %ith the design of ram'ets for the 0A-$/ s(personi bomber and the SR-$ reonnaissane plane.

=nother problem %as the prod(tion and testing of large booster ro4ets. These had to be ten times larger than anything e2isting. The Talos Aooster History  page desribes the problems and sol(tions d(ring boosterdevelopment. Lessons learned from the Talos booster development pro'et paved the %ay for f(t(re large solid f(el booster ro4ets for *A5s" satellite la(nh vehiles and the spae sh(ttle.

=nother phase of the pro'et onentrated (pon reating a more effetive %arhead for the missile to allo% high 4ill probabilities at greater ranges than possible %ith the %arhead types in (se in )orld )ar **. The )arheadHistory page desribes this effort.

= large effort %as beg(n to develop telemetry methods to ret(rn data from e2perimental test vehiles. S(itable methods %ere none2istent at the beginning of the pro'et" and the telemetry pro'et %as as m(h of a designeffort as any other part of Pro'et A(mblebee. *t %as neessary to monitor the missile in flight to meas(re its performane and provide information in ase something didn6t %or4 right. = simple E%irelessE system %asdeveloped to allo% transmission of p(lsed or mod(lated tones that o(ld be translated into (sef(l information. @arly telemetry systems %ere b(ilt %ith T f(Be omponents and the ne% s(b-miniat(re va((m t(bes. Fo(rto eight F5 arriers %ere transmitted at #/ to ?/ 5HB and later 9// 5HB. @arly data reordings %ere on phonograph-reord-li4e dis4s. Paper strip vis(al reordings of osillosope displays %ere also (sed. Later thene%ly developed magneti tape reording %as (sed. The early A(mblebee telemetry system %as event(ally developed into the ommon helial antenna that beame the standard F5CF5 US telemetry system. # 

)hile e2periments %ere proeeding %ith ram'et missile development entirely different smaller s(bsoni test vehiles %ere developed for initial tests of the beamriding sheme. These initial beamriding test vehiles %ererelatively simple short range ro4ets (sing e2isting tehnology to allo% an early start on testing g(idane systems. The +(idane and Homing History page provides details of the development effort.

The beam riding sheme that %as devised had t%o phases. *nitial la(nh %as into a %ide apt(re beam. The missile mane(vered to the enter of this beam" and then the beam %as narro%ed to a thin g(idane beam to

diret the missile to the target. =n antenna in the tail of the missile deteted the g(idane beam. Position information in the beam %as deoded and onverted to %ing ontrol ommands to steer the missile into the enterof the beam. This had never been tried before and a lot of e2perimentation %as needed to design and test vario(s ideas. =s the missile range inreased the diameter of the g(idane beam broadened" red(ing a(ray ofthe beam rider method. =t ranges of t%enty miles and more the g(idane error %as too great to ens(re a high probability of destroying a target. # 

S(personi test vehiles 1ST3 %ere designed to test steering and ontrol d(ring s(personi flight. These %ere more advaned t%o stage ro4et po%ered test vehiles that inorporated the beamriding g(idane systemsdeveloped %ith the smaller s(bsoni beamrider test vehiles. The ST-7 test vehile %as the most omple2 of the solid ro4et po%ered vehiles. *t %as la(nhed by a solid ro4et booster and had a small solid ro4ets(stainer to propel it at s(personi speeds to a range of abo(t ten miles.

*n <!? the ST-7 %as reogniBed as having potential as a short range antiairraft missile that %o(ld meet most of the initial A(mblebee goals if the telemetry setion %as replaed %ith a %arhead. This missile o(ld beoperational before Talos and %o(ld give the fleet greater anti airraft apability than e2isting g(ns. = deision %as made to proeed %ith a separate program to develop a prototype missile and it %as given the nameETerrier.E This %as the progenitor of the modern Standard missile (sed %ith the (rrent =egis missile system.

Extending the range

Sine the proposed Terrier missile o(ld interept short range targets the goal for A(mblebee %as e2tended to 8/ miles and a re(irement for terminal g(idane %as added. This hange of plans a(sed s(bstantial re%or4of the design and added some delay in the development of the missile.

*nitial plans %ere for Talos to (se beamriding for mido(rse g(idane after it separated from the booster ro4e t. *t %as tho(ght that the missile o(ld ride the target tra4ing radar beam to the target. Ho%ever" as rangeinreased the diameter of the g(idane beam beame greater" allo%ing the missile to %ander farther from the beam enter. This meant that the distane from the target at interept beame greater %ith inreasing range"and at distanes of more than / miles 4ill probability %as (naeptably lo%./ 

To meet the longer range goal a separate g(idane radar beam %as neessary. = tra4ing radar provided information on the diretion to the target and the g(idane radar generated the beam for the missile to follo%. This beam arried information that allo%ed the missile to determine its position %ithin the beam and steer to the beam enter. Ay ontrolling beam position the ship g(ided the missile to the viinity of the target. This shemehad an additional benefit that several missiles o(ld be g(ided to a target along one g(idane beam./ 

@arly tests sho%ed that the missile %o(ld ons(me too m(h f(el if it fle% diret line of sight to a long range target at lo% altit(des %here air density %as greatest. *t %as deided to (se the beamriding beam to diret themissile to high altit(des %here it operated more effiiently in thinner air and then diret it to a point of interept %here it %o(ld dive on the target.

= terminal g(idane method %as needed" and a semiative radar homing 1S=RH3 see4er %as hosen. =t the end of the mido(rse beamriding phase the ship sent a signal to the missile to arm the %arhead and ativate thehoming system. The la(nhing ship ill(minated the target %ith a homing signal that refleted from the target. The missile6s see4er deteted the refleted signal %hih g(ided the missile to the target. This gave a terminalhoming system %ith high a(ray that %as not affeted by the distane from the ship to the target.

The design of the ram'et missile %ith the large air inta4e opening at the front posed a problem. The ommon %ay to implement a radar see4er %as to (se a steerable paraboli antenna to detet the homing signal" b(t this%o(ld interfere %ith the operation of the air inta4e. =n interferometer-type antenna %as hosen for several reasons. *t (sed fo(r small %idely spaed antennas that o(ld be mo(nted aro(nd the air inta4e and %o(ld notinterfere %ith ram'et operation. These antennas %ere m(h smaller and simpler mehanially than a gimbal-mo(nted sanning dish antenna. This arrangement had a very %ide target a(isition apert(re and %o(ld allo%rapid target a(isition %itho(t having to provide the missile %ith information abo(t the diretion to target. / 

= s(personi @2perimental Prototype 5issile 10P53 design %as reated that had all the neessary f(ntions of an antiairraft missile. This %as to have the initial Talos missile airframe and %o(ld ombine the prototypeengine" f(el" ontrol" g(idane" homing and %arhead systems that ame o(t of the test and development programs. This test vehile event(ally beame the operational Talos missile.

*n <8 development began on a small n(lear %eapon to be arried by fighter-bomber airraft. *t had a smaller diameter than the Talos missile so it seemed ideal for adaptation as a missile %arhead. Talos ) %o(ld beg(ided to the target %ith the beamrider system and detonated on ommand from the ship. =t ma2im(m range beamriding %as ina(rate and re(ired a 4ill radi(s of /// to 9/// feet.

The n(lear %arhead re(ired a longer missile and moved the enter of gravity for%ard. =s a res(lt the missile %as more stable than the onventional version b(t not as mane(verable. This %as not a problem for then(lear armed missile bea(se it did not have to get as lose to the target to ahieve a 4ill.! The first prototype ) missile %as tested in <87" ? months after the design %as started.

First Tactical Talos RIM-! "#!M-$-%b& and RIM-B "#!M-$-%bW&

This %as the first version of the Talos missile. *t arried a onventional fragmentation rod %arhead in an ann(lar spae in the missile nose s(rro(ndingthe ram'et t(be" behind a small ompressor innerbody. The n(lear %arhead %as m(h larger than the onventional %arhead and %as ho(sed in alarger innerbody that served as the inta4e ompressor. The R*5-?A n(lear missile %as longer than the onventional R*5-?= missile. The hominginterferometer antennas %ere removed from the n(lear version along %ith the assoiated homing eletronis.

The onventional version (sed a see4er that homed on the refleted p(lse mode tra4ing radar signal.! This system %or4ed %ell against mid to highaltit(de targets and the ma'ority of interepts prod(ed s4in-to-s4in ontat %ith the target. A(t %ith lo% altit(de targets the tra4ing radar ill(minated s(rfae ob'ets a(sing many false signals that hid the target. / The missile did have effetive home on 'am apabilities.

*nitial First Tatial Talos missile 1S=5-N-#b3 %as flo%n in <89. *ntrod(tion into the fleet %as delayed by lengthy ship onversions" and the missile%as finally deployed on the USS Galveston L+-7 in <8?.

Extended Range Talos RIM-' "#!M-$-%b(& and RIM-D "#!M-$-%bW(&

Development of a longer range missile %as started in <87" partly in response to =ir Fore interest in (sing Talos to defend Strategi =ir ommandair bases. The range %as e2tended from 8/ to // miles and altit(de eiling %as inreased from #/"/// feet to $/"/// feet. The Talos @R missile %asfirst flo%n in <#.

The ne% design %as more effiient" having greater mane(verability" lo%er mane(ver-ind(ed drag and greater thr(st. *t o(ld engage faster and moremane(verable targets. Flight speed at high altit(des %as inreased from 9/// to 9!// feet per seond 1#// mph3. The missile tail fin span %asinreased to improve aerodynami harateristis. The f(el tan4 %as lengthened to give 9/: greater apaity. The omb(stion hamber %aslengthened # inhes for better high altit(de omb(stion effiieny. The engine inlet %as redesigned to a do(ble one to improve thr(st at highaltit(des. The booster %as made larger to give an ade(ate la(nh speed for the heavier missile.! 

@2tended Range Talos had separate optimiBed apabilities for the t%o versions. The original homing eletronis re(ired more spae than %asavailable in the n(lear version. Ne% ompat eletronis %ere developed for the Talos ) for beamriding" ontrol system and beaon transponder"

and these %ere event(ally integrated into the onventional version.

= ne% ontin(o(s %ave 1)3 see4er %as developed that (sed the Doppler effet to disriminate bet%een lo% altit(de targets and ba4gro(nd l(tter. The ship omp(ted the losing rate of the missile and target andtransmitted Doppler shift information to the missile in the tra4ing radar beam to improve target a(isition times.

The ne% see4er eletronis %ere essentially imm(ne to 'amming" and o(ld disting(ish bet%een m(ltiple 'amming so(res and home on the losest.

The ne% ) g(idane system %as effetive against s(rfae ship targets even tho(gh the Doppler shift %as the same for the ship and the oean. Several improvements to the eletronis inreased the signal to l(tter ratios(ffiiently for the missile to identify the target.

The LR missile had a (ni(e g(idane system based (pon gro(nd 1ship3 proessing of target information sent bythe missile. The Typhon 5R medi(m range missile %as to be a modified Tartar missile.# 

The Typhon system developed a phased array radar (tiliBing ne% solid state tehnology and digital omp(ters that o(ld respond (i4ly and deal%ith many targets.

@vent(ally the omple2ity of the phased array radar and assoiated omp(ter systems e2eeded alloated f(nding. The design onepts %ere beyond the ability of e2isting man(fat(ring apabilities. @ven tho(gh anoperating Typhon system had been installed in the USS Norton Soun  =5- and the Typhon LR missile had proven reliable d(ring in-flight testing" the missile o(ld o(tperform its radar and g(idane systems" so it %asaneled in late <#8. The f(nds %ere transferred to improving e2isting Talos" Terrier and Tartar systems.# The prototype Typhon fire ontrol system later evolved into the =egis %eapons system.$
