The buildup-spurred by the Soviet presence in was used in this report. Vietnam and, for Indonesia and Malaysia, the perception of a longer term threat by China-is intended to improve surveillance and defense capabili- ties over these straits and their eastern approach, the South China Sea. To- tal defense spending this year by the three is budgeted at more than 70 per- cent above the 1979 level: ? World War II vintage ships are being replaced by modern, missile- equipped craft. ? Major improvements are being made in fighter and surveillance aircraft fleets. ? A greater number of joint bilateral military exercises are being under- taken. 25X1 At present, surveillance of the approaches to the straits is poor, and the military forces of the three ASEAN states have a limited ability to defend against an aggressor. Assuming their current five-year plans are carried out and followed up by a continuing modernization effort, however, their forces will pose a respectable challenge by the 1990s-at a minimum, attaining the Singaporean goal of being a "poisoned shrimp" for a major power aggressor. 25X1 Financial problems could stretch out implementation of plans for the buildup. In Malaysia, where low raw materials prices have reduced foreign exchange receipts, some planned hardware procurements are being delayed and operations reduced. Al- _25X1 though we have not yet seen any reductions from planned levels in Indonesian military programs, we expect economic constraints to force delays in force improvements and encourage Indonesia to look abroad for additional assistance and concessionary financing for future military purchases. Even Singapore, with its varied, fast-paced economy, recorded a sharp decline in export growth during the first half of 1982, perhaps presaging some military budget cuts FA 87-101070 September 1982 Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7 Approved For Release 2008/08/05: CIA-RDP84S00554R000100160004-7 Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7 Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7 Secret 25X1 25X1 The Straits of Malacca and Singapore: Status of _ 25X1 the Defense Buildup F Importance and Vulnerabilities of the Straits The Straits of Malacca and Singapore are one of the world's busiest maritime passages forming the short- est sea route between the Indian Ocean, the South China Sea, and the Pacific Ocean. The waterway is a lifeline for East Asian exports to European markets and oil imports from the Middle East. The straits also have strategic importance for the United States and the Soviet Union because of the growth of their Indian Ocean naval forces. Use of other routes through the Indonesian archipela- go would cause costly delays. The most viable deep- water alternative is the Lombok Strait between Bali and Lombok, although use of this strait adds four days to a typical Japan-Middle East tanker run. Its deep, 11-mile-wide channel already is used for super- tankers too large for the Malaccan Strait. The Sunda Strait to the Java Sea is the shortest alternative route to the Malaccan/Singapore Straits, but the shallow- ness of the Java Sea, local traffic congestion, and the many offshore oilwells restrict its use. The Ombai/ Wetar is the third major strait through the archipela- go. Should a dispute affect all of these options (all involve Indonesian waters), traffic would be forced around Australia-a route that would add more than two weeks' travel time between the Indian Ocean and The Straits of Malacca and Singapore are vulnerable to interdiction either by mines or small craft armed with missiles. Mines are particularly suitable because navigable channels are narrow in places and tidal currents are not a significant problem. The straits were successfully mined by air in World War II by the Allies. Neither the littoral states nor Australia has the ability to clear the waters of mines quickly, because they lack sufficient mine countermeasure assets. The straits of the Indonesian archipelago are equally susceptible to mining, with the exception of the deep Ombai/Wetar Strait, which has strong tidal currents. Concerns Over the Straits and South China Sea The Southeast Asian nations have long been con- cerned that China will project its influence southward into the South China Sea and the Singapore and Malaccan Straits. Although still a long-run worry- particularly for the Indonesians-the ASEAN na- tions now publicly call the Soviet Union and Vietnam the greater threat in the near term. LOA-1 Concern over Soviet intentions in the area increased in 1980 when the USSR signed a defense and oil 25X1 exploration agreement with Vietnam. The agreement commits the Soviet Union to assist Vietnam in explor- ing for oil and gas on Vietnam's continental shelf and in the South China Sea-the eastern approach to the straits. The worries of the ASEAN states are fueled not only by concerns over Soviet strategic interests it the area but by Vietnam's sweeping claims over the 25X1 South China Sea that conflict with the claims of China and each ASEAN nation except Singapore. Since 1979 the Soviets have maintained a naval 25X1 presence in the area. With modification, the Vietnamese facilities could 25X1 provide a base for air cover for Soviet naval operations in the South China Sea down to the straits. In addition to the external threat, the littoral states 25X1 have to cope with piracy and smuggling, perhaps the most acute security problems in the area. The combi- nation of high Indonesian tariffs and the proximity of Singapore as a commercial entrepot makes smuggling profitable. The Indonesians lack both the surveillance and patrol craft to interdict this traffic. As to piracy, attacks have been on the increase; more than 40 major incidents have occurred over the past two years. Four oil tankers were attacked within the space of five weeks last year.

Over 200 miles wide at its western entrance, the strait constricts to 8 miles at its eastern end adjoining the Strait of Singapore and has a navigable channel less than 2.5 miles wide at some points. The navigable channel has a minimum depth of 23 meters, allowing it to handle full vessels up to 225,000 deadweight tons. The 70-mile-long Singapore Strait completes the interoceanic link. Bound by the Malay Peninsula and Singapore on the north and the Islands of the Riau Archipelago on the south, the strait has a minimum breadth of 3.2 miles, with a navigable channel 1.8 miles wide at this point. Around 180 ships enter the Malacca/Singapore Straits daily. More than 1.3 billion barrels of oil transit the straits each year, in 1981 about half of Japan's oil came through this waterway. South Korea and Taiwan depend on the straits for nearly all their oil. The straits are also the primary sea link for manufactured goods and raw materials sold by the East Asian economies to Europe. In addition, the straits play a vital role in commerce between the littoral states-Malaysia, Indonesia, and Singapore. As to military traffic, 65 Soviet naval vessels entered the straits last year. The United States also uses the straits to service its Indian Ocean Squadron out of the Philippines and Hawaii. Current Defense Capabilities Indonesia, Singapore, and Malaysia have only a limit- ed capability to conduct surveillance over the straits and their approaches much less defend them. Modest naval forces are their strongest military asset. Indone- sian resources include three corvettes armed with guns and Exocet missiles, seven older frigates, two submarines, and numerous patrol craft suited to inadequate maintenance, a poor logistics system, and lack of trained personnel limit the performance of the Indonesian Navy. Malaysian and Singaporean naval forces are more modest; neither has a deepwater capability. Their fleets consist mainly of patrol craft effective in coastal areas and in the straits themselves. The Indonesian and Malaysian Air Forces have mini- mal strike capability. Malaysia has only five or six obsolete Canadair Tebuan fighters for ground attack. Both forces suffer from a shortage of experienced pilots, lack of technicians, and inefficient aircraft maintenance. The Singaporean Air Force is more impressive, possessing a strong ground attack capabil- ity comprising two attack squadrons equipped with 34 A-4S Skyhawks. 25X1 Maritime surveillance of the approaches to the straits is another serious shortcoming. Singapore currently has no aircraft dedicated to surveillance, although Embassy reports indicate it plans to buy three E2C Hawkeye reconnaissance planes from the United States; Malaysia's surveillance effort is poor because of crew and maintenance problems. Indonesia has a large airborne search force, but it too suffers from a lack of trained personnel. Coverage by land-based radar in each of these states is inadequate. 25X1 25X1 25X1 25X1 25X1 Approved For Release 2008/08/05: CIA-RDP84S00554R000100160004-7 Approved For Release 2008/08/05: CIA-RDP84SO0554ROO0100160004-7 ?

The buildup has concentrated on the purchase of modern ships and aircraft and the introduction of new missile systems. These countries are also targeting improved personnel training. When completed, the modernization programs will improve maritime and air surveillance capabilities and enable the three countries' armed forces to present a credible deterrent. The countries are im- proving early warning and air defense capabilities by using ground-based and airborne surveillance sys- tems, and by adding advanced fighter aircraft and antiaircraft missiles. Maritime defenses are being bolstered with the addition of missile-equipped attack craft. Indonesia's five-year defense development plan (1979-83) is the most ambitious modernization effort in 20 years. The plan is also more outward looking than previous efforts that concentrated on internal stability. Jakarta has upgraded and redeployed mili- tary forces to positions bordering the South China Sea and has expanded its airbase and support facilities at Grand Natuna Island. Since 1979 Indonesia has procured about $1.3 billion worth of new air and naval equipment. Fourteen new naval combatants have been added-including Exocet-equipped frig- ates-while the Air Force has received new A-4s and F-5s, as well as helicopter and transport craft. Jakarta has also purchased a new ground-based radar system from France and is in the process of acquiring Boeing 737 aircraft for surveillance. In addition, senior Indo- nesian defense officials have approached the United States Government to buy some F-16 fighters and Harpoon antiship missiles. The Fourth Malaysian Plan announced in March 25X1 1981 called for $4.3 billion to be spent on defense during 1981-85, continuing the force expansion began in 1979 that was intended to double the armed forces by 1983. The plan envisions procurement of tanks, armored personnel carriers, artillery, naval combat- ants, and attack and fighter aircraft, as well as the Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7 Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7 Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7 Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7 Secret 1,764 1,788 2,503 2,622 1,406 1,466 2,026 2,917 506 622 712 791 3,677 3,877 5,242 6,331 Table 3 Indonesia, Malaysia, and Singapore: Real Defense Spending a Indonesia Malaysia Singapore Total 1,386 1,878 1,906 1,025 975 1,095 386 421 512 2,798 3,274 3,514 2,068 1,166 488 3,723 a Deflated using national GDP deflators. b Converted at June 1982 exchange rates.

Guided missile corvettes and mine hunters also are in the plan. A follow-on phase would provide further equipment and the support organizations needed for the new forces. Singapore has been committed to developing a credi- ble deterrent force since its independence in 1965. Realizing that its small size, strategic location, and economic prosperity make it vulnerable to aggression, Singapore has developed a strategy that calls for making such an attack on it unacceptably costly. The US Embassy in Singapore estimates that by next year a sophisticated air defense system incorporating surface-to-air missiles, F-5E and A-4S aircraft, and a ground radar command center will be operational. The Embassy further reports that since the Falklands confrontation, Singapore officials have indicated greater urgency in improving early warning and com- mand and control capabilities and intend to buy three E2C reconnaissance aircraft Growing Economic Constraints 25X1 Although military spending plans still remain largely on track, the global recession is beginning to cause these countries to review their planned spending lev- els. The weak oil market is cutting deeply into Indonesia's foreign exchange earnings. Oil export earnings are presently running some $10 million per day below 1981 rates. As a result, Indonesian Govern- ment receipts have also been reduced-taxes and royalties on the petroleum industry account for some 60 percent of Jakarta's revenues. In a similar fashion, the Malaysian balance of payments and terms of trade have deteriorated as tin, rubber, and timber prices dropped sharply in 1981, resulting in the first decline in export revenue since 1975. Manufactured exports, which grew rapidly in 1980, fell 17 percent last year; demand was particularly weak for electroni25X1 components and textiles. Even the well-balanced Sin- gaporean economy is beginning to feel the impact of the recession. Growth in real GDP fell to 7.3 percent 25X1 Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7 Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7 Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7 Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7 Secret 25X1 25X1 in the first quarter of 1982-the worst performance in four years. Output in the electrical goods and elec- tronics sector declined by nearly 7 percent; in the first half of 1982 export growth slowed. Implications 25X1 Recession-induced cuts in defense budgets will, we believe, probably lead Malaysia and Indonesia to put less pressure on the United States and other suppliers for early delivery of advanced military aircraft and 25X1 The tightening economic situation has already affect- ed the Malaysian defense budget. Prime Minister Mahathir has indicated to Malaysian Defense offi- cials that military spending goals for 1981-85 will not be met on schedule. DIA reports that there are indications that this year's defense budget may be reduced as much as 20 percent and that cuts next year may be even greater. In July the Malaysian Air Force postponed the planned purchase of 16 F-5 E/F fight- ers because of a moratorium on such purchases by the Finance Ministry. According to the Air Force Chief of Staff, only essential equipment and training will be funded through 1983. In addition, the activation of additional Malaysian combat units has been canceled for budgetary reasons. As a result, Malaysian defense expenditures in the first three months of 1982 were almost 30 percent below year-earlier levels. Although we believe Indonesian military programs have not yet been affected by the recession, they are likely to undergo cutbacks should oil prices not rise from current levels as most analysts now expect. In such a case, we believe Indonesia will look abroad for additional aid and concessionary financing of military purchases. Both general force improvements-train- ing, barracks modernization, and ground force expan- sion-and improvement of military capabilities along the strategic northern flank of Indonesia-Sumatra, Kalimantan, and Sulawesi would be slowed. We do not believe plans for the acquisition of advanced defense systems will be shelved but rather stretched over a longer period of time. Singapore's defense budget is the least likely to be affected by the global recession in our view. The city- state boasts a well-balanced economy that can ride out even extended recession. Furthermore, the current modernization effort will be essentially complete with- in the next year or two. perhaps ask to stretch out purchases. Certainly there will be increased pressure for US credits. ing a mix of Harpoons, Exocets, and Gabriels, we believe the share of Harpoon acquisitions in future planned acquisitions may drop. In any case, we expect the United States to remain the supplier of choice for most advanced weapons systems even if economic pressures increase comparative shopping in Europe. 25X1 Even with delays in planned hardware purchases, we believe the military forces of the three littoral states will evolve into a more credible deterrent as the 25X1 decade progresses. Purchases of defense systems have already made these states a more potent force than they were only two or three years ago. Added surveil- lance capability will greatly improve the usefulness of these systems. Proper training and maintenance re- main the most significant constraint on the efficacy of advanced weaponry in Indonesia and Malaysia. More- over, we believe defense cuts could come in these areas, exacerbating existing deficiencies and thereby negating the usefulness of newly acquired defense systems. 25X1 Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7 Secret Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7 Secret Approved For Release 2008/08/05: CIA-RDP84SO0554R000100160004-7
