Some support facilities were obtained at Cam Ranh Bay during this period, but auxiliaries provided most of iltc services al the porl while naval transport aircraft provided the support for the Bears at the airfield.

This force was adequate, however, to undertake some of the missions that the Soviets would assign to out-of-area forces during the transition to and early phasesS-Soviei war. The most important of these, and one common to out-of-area units, would be lheof up-to-date intelligence and targeting data oo major US and allied naval forces, such as aircraft carriers and plat forms equipped with cruise missilt potential nuclear threats to the Soviei homeland.

did noi have the benefit o( itrikc aircraft, however, and probably would have been capable of limited interdiction of tea lines of communication (SLOC) only in tbe absence of significant Western assets. Tbe lack of adequate support facilities for vrartutre use ia all distant area formations, including Cam Raxth before the boildap. further limited the mbiliTy of this force for combat with Western forces and its ability toampaign against Western SLOCshort period.'

A second general mission for out-of-area formations almost certainly would be lo delay and divert Western naval and air forces from higher priority missions nearer the Soviei Union. The force present at Cam Ranh in the, though small, might have been sufficient to divert significant Western forces, such as one or more aircraft carrier battle groups or US Air Force formations.

According to Soviet doctrine and exerejses.ignificantly largertwo or more regiments of missile-equipped aircraft, submarines, and surface-launched antiship cruisebe requireduccessful attackestern carrier battle group.

Significance

We believe that the Soviets regard most unitsto distant waters in wartime to be expendable, particularly in exchange for the delay, diversion, or destruction of Western carriers or oiber nuclear-capable units far from the Soviet homeland and the operating areas of SSBNs. If such Western units were noi in the region at (he onset of hostilities, we believe that (he squadron would still remain in the Souih China Sea. If Cam Ranh were operational, the force could undertake some limited offensive operations, not only for the damage tbey might cause, but to increase the possible diversion of Western forces to the region, for example, by attacking US bases in tbe Philippines and SLOC interdiction.

Attacking US Baits in iht Philippines, The Badger squadron couldaid or scries of raids, depending on the rale or casualties, against the US bases using bombs against land targets, aniiship missiles against ships at Subic Bay, or mines against Subic, other ports, and Philippine waters. Thewould be beyond the range of fighter escort byoggers at Cam Ranh.

SLOCe Badgers could mount anti-SLOC strikes against shipping in the region. The Badgers aad theSW aircraft, as well as submarines and surface units al Cam Ranh. could undertakein defense of Cam Ranh and against sea lanes and straits General purpose submarines in the region could also be used in an ami-SLOC role, although (he lusiainabilliy ofampaign depends on tbe continued existence of support auxiliaries at Cam Ranh for replenishment and ordnance resupply. (

Alternatively, without the presencearrier or other priority targets, the Soviets couldore passive strategy, dispersing their own forces to alter* nate airfields, ports, anchorages, or operating areas. Limited ami-SLOC missions couldart of this strategy, via mining or submarine attack The Soviets would hope to tic down Western forces Ihat might already be in the area, tech as ASW aircraft aod nuclear attack submarines, and potentialto theair formations or aircraft carriers fora not inconsiderable amount of time.

We believe that in any likely scenario at the onsetS-Soviet war the Soviets would probably have more io gain by leaving the squadron in the South China Sea than by attempting to pull it back io the main Pacific Fleet wartime operation areas before or during bostihties. The squadron israction of the force available to the Pacific theater ia wartime andmainly of older, less capable platforms. Tbe relative perrxption of tbe capabtUt&of tbe force, however, is magnified by iu deptoymenl to tbe Souih China Sea. This is especially the case because tbe future of US bases in the region may be in doubt.

Future DeselopmenU

Tbe command and control, communications,and logistic facilities al Cam Ranh Bay are takingore permanent nature, suggesting the Soviets intend toong-term commitment toaval presence ia the region.

We believe that the gradual improvement of forces and support structure at Cam Ranh will continue.

Mosl ol ihe deployed forces, however, probably will continuee older units or small numbers of newer, more capable lypes as modernization of Ihe Pacific Fleet com forward,

Aviation. The Soviets apparently view the current strencih of Ihe Badger unit at Cam Ranh to be adequate (seehe airfield couldtwice the number of Badgers deployed,umber of Badgers are in storage in the Pacific Fleet.

Constraints of numbers aod missions make increasins theomponent at Cam Ranh unlikely also.'

Air Defense. Increasing tbe number of fishier aircraft at Cam Ranhossibility. If the Soviets wish to upgrade the air defense of Ihe base further, however, they might introduce Soviet surface-io-air missile units or equip the present Vietnamese air defense forces in the region with more modern systems.

and the flexibility they oiler the Soviets for the various missions they may undertake in Ihe region, p

We do not believe that any or al) of these possible developments would seriously alter the wartimeor missions of the South China Sea squadron. Tbe anticarrier warfare and anti-SLOC roles of ibe force would bcnefil from additional strike aircraft or submarines. The defense of Cam Ranh itself might improve tubus ntially with deployment of more Soviet air defense units or equipment, i

The expansion of logistic and support infrastructure al Cam Ranh will probably at least marginallyIhe capability of theajor shift from Boating auxiliary support to onshore support at tbe port would create more space for combatants and other nonsupport ships. This seems an unlikelyfor Ihe Soviets io make, although the presence of auxiliary ships seems to be gradually declining as the buildup continues. Construction of extensivestorage facilities for the air unit at Cam Ranh wouldreater number and variety of types of ordnance to be available, such as iron bombs, aerial mines, and chemical weapons, as well as aniiship missiles. '

Combatants. The current patlern of assigning relatively small combatants to Ihe squadron, such as Grisha and Pctya light frigates and Nanuchka missile combatants, will probably continue. This reduces the need for larger surface combatants to deploy to Cam Ranh and may help to reduce the congestion in Ihe port area, f

General Purpose Submarines. The number ofat Cam Ranh has fluctuated between three and six in recent years, although on average only three submarines were presente expect tbe current level of deployment of three lo continue, both because tbe Soviets apparently view it as adequate and because our projected force estimates of the Soviet Pacific Meet indicate the lack of extraThe mix of aniiship cruise missile submarines and torpedo attack dieael-powered submarines will also probably continue because of iheir availability
