Sup Toward Respeclabua-y

In the summer1 tbe CbQcctno Guide finally took shape. It described tbe reporting needed to follow Soviet maritime arms traffic, and It included all photographs possible of Identifiable deck cargoes. It correctly klerrcrbed the crates forndet tighten,elicopters,ombers. Although ftelatively primitive effort, the putting It together had been good exercise to the nse of intelligence from all sources. Thedentifkatiao depended on the cited BAP recorrnaissance mission to combination with clandestine reports from Iraq-and the UAR and an East European defector's sketch of the crate.

were generally skeptical about bow much interest or effort it would

arouse. To their surprise, it stimulated considerable Interest faon arms shipments, including photography and reports on crates and tbe contents of crates. Observersstanbul but also In the UAH, Indonesia, and other countries where Soviet arms aid fa prominent began to increase their reporting on crates. This enhanced awareness of cratesource of information on Soviet military aid led gradually to tbe solution of addition*!problems. At the same time tbe acquisition of most of the major documents concerning Soviet-Indonesian arms dealsold mine of detailed data on Soviet military aid practices,mdudmg information useful In solving crate puzzles. Similar information obtained later fn Iraq also contributed substantially to the development of cratology.

The Cuban Buildup

By the rime2 Soviet military buildup to Cuba started fa Jury, cratology was an established technique, bat its adherents were confusedery small cnele. It was not accepted fa many quarters of the community, and coordinated Intelligence based on crate countsarity. Nonetheless, what knowledge there was of crates was tocorporatcd Into the efforts that were being made to bolsteron Cuba. Photos of ideritrfiable crates were includedarge Cuba collection guide, and efforts to improve the monitoring of Soviet shipping were continued Bnt because so many fa the fatelh'gence community were unconvinced of the usefulness of theseonrtation on the first military shipments of the buildup was moat Incomplete.

Tbe first military shipments were detected as they left the Black Sea fa mid-Jury, and steps were taken immediately to provide for pliotographlng all ships and kientifymg any significant dock cargoes; joint ONI-OA efforts at tbe Bosporus bad improved considerably byut now many of thesenfortunately transited tbe straits at night or fa bad weather, making photography impossible.

izable numberbe military shipments were for tbe first time made from Soviet Baltic ports, where our capabilities were rather limited. And In the Atlantic there was no adequate network to cover Soviet shipping and get photographs. Thus not all of the ships carrying military cargoes were photographed during the first sir weeks, and the results on those that were were seldomm rime to be useful By mid-August the system for ship photography was much improved, but ft was not perfected until after

Gradually, however, the pictures belatedly came in. Cratesthe decks of two ships accounted for atew more. These, along with somephotographyobserver reports, led to the conclusion thatere at keas*rfc* Kj^<wv

Cratology received Its vindication onctober, when aerial photography over Santa Clara showedully assembledighters, as well as four other aircraft identified as probablebe acbievenvant was lost In tbe crush of events, of course, for by now the photos of medium-range missiles bad touched off the oh-mactlc East-West confrontation. Nevertheless tbeuildup of high-performance jet fighters fn Cuba bad been of considerable value. Without the warning provided by cratology, the rnilitary planners who went into crash programs In October would have been far more startled by the photos ofh showingoeady to bolster Cuba's air defense system.

From Defeat* to Offense

While the resolution of theontroversyriumph for cratology, the moat important contribution tbe technique made to the Intelligence effort fa the Cuban rrnU'rp was fn identifyingombers.ever leads to another significant conclusion, this one achievement assures cratology atmall niche fn theof intelligence.

In early October the increasing tension generated by the buildup was illustratedisputearge "cello-like" object seen on tbe deckhip. The container was large enough for anyariety of aircraft, induding theeapon of offense

The cralologists. however, were sure thattructureaircraft, being exactly the same as those usedo Cuba. Again argument flared over the validityanything about contents front tbe shape of aon deck. This trine, however, the negative concluiioostructure probably did not contain anomberimely clandestine reporthotograph froman aircraft being loaded onto a

Aerial photography bad established thatuildupumber or defensive systems, but ground observer reports increasingly suggested sterns which could not be reconciled with defensive measures. Two observers reported the arrival ofomber crates abouteptember, and at least one of the two had based his identification on photographs ofrate* in the Cuba collection tprlde. As usual, these reports were not consider rd "hard" evidence, although sn retrospect at least one was valid.

Tbe moment of troth for cratology occurred onctober, when the first photographs ofrates en route to Cuba reached bead-quarters. Taken oneptember, these showed the Soviet ship EUsfcnov carrying ten crates which could only be forombers. To make doubly sure and to convince others, however, the cratolo-gists drew together all tbe precedents andand report from tbe naval officer to Djakarta showing an end section of the crates, the Indonesian document giving the dimensions forontainers, an old picture from Istanbul showing such crates being shippedecent Istanbul photo showing therate still in usehip en route to the UAR, and of course tberepeats that the bombers had recently arrived in Cuba. Awas prepared for the DCI reporting the new Information and detailing the basis for the weighty conclusioo.

Tbe observer reports which during tbe previous three weeks had pointed to the pea.ilnlityadical change fn the nature of the military buildup in Cuba had not been generally accepted as firm. They had raised the flag of caution, but so-called hard evidence was requiredoodusaon that there really had beenhange. Therates provided this evidence.

As the crisis receded and efforts were directed toward sorting out the pieces and reviewing the status of Soviet forces on theew other bits of cratology were ptrodrxed. Largely by means of crate counts, for instance. It was discovered thatoviet helicopters bad been delivered to Cuba, perhaps two-thirds of them during the buildup. The size of this formidable countramsurgency weapon In Cuban hands waa not apparent from other sources. Crates for two types of cruise missies were also identifiedesult of the repeated high and low altitude photography over Cuba, andthe information has since proved useful fn other countries.


The upshot was acceptance of cratology; the Cuban experience demonstrated that thisegitimate tool for tntcQigence analysts.roader sense, ft demonstrated the way many of the intelligence community's resources cast be successfully combined to solve asort of problem which normally looms large forew specialists but fn this Instance took on greatly Increased significance.

Oddly enough, despite public attexrbon to cratology. the Soviets do not seem to have radically cliangod tl>eh" procedures In shipping arms abroad.
