Japan Steps Up to a Stronger Defense

Nov. 1, 1989

Japan’s military buildup, once dismissed by many as a project doomed to fail, is proving to be a surprising success at a time of mounting problems for Western de­fense.

When Tokyo unveiled its plan in 1986, numerous analysts wrote it off as unlikely to go very far. Japanese advances, however, are forcing a re­assessment of military prospects for the island nation of 123,000,000 cit­izens.

Impressive strides have been made in overcoming an acute lack of modern arms that has hampered the 245,000-man Japanese Self-Defense Forces. The SDF, though small, will possess some of the world’s most advanced aircraft, warships, ground combat weapons, and communica­tions equipment.

Among these systems are F-15 in­terceptors, Patriot air-defense mis­siles, AEGIS-equipped destroyers, Yushio-class submarines, new tanks, sophisticated communica­tions, and advanced SX-3 fighters.

Japanese defensive capabilities are growing steadily. The judgment of the Pentagon now is that by 1991, Japan will achieve a minimum force level required to carry out funda­mental defense missions. Pre­viously, Japan fell far short of that goal.

Expanded defense budgets, high-technology prowess, and—until re­cently—strong domestic political stability all have contributed to the Japanese turnabout on defense.

For the US, Japan’s progress is a boon as Washington confronts pres­sures to cut Pentagon budgets and signs emerge that military efforts will decline sharply in West Europe­an nations. Events in Japan shape up as a singularly positive develop­ment.

One thing has not changed. US protection, codified in a 1960 de­fense treaty, remains the bedrock of Japan’s security.

Also, Japan’s involvement with military power still stirs controver­sy. Asian neighbors harbor concern about how far Japan may go. In Con­gress, by contrast, Tokyo is con­demned as a piker, free-riding on the back of the United States.

Tokyo’s new military effort comes as an addition to a broader Japanese thrust that is expanding its influence. Japan’s $2.5-trillion economy has helped make it the world’s greatest supplier of capital. Japan is set to become the largest foreign-aid donor. Even on the dip­lomatic front, Tokyo has begun to make waves.

A “Major Military Power?”

Surveying Tokyo’s defense plan, Henry Kissinger declared not long ago that “Japan will emerge as a ma­jor military power in the not-too­-distant future.”

Well, maybe, but the former Sec­retary of State might have been lay­ing it on a bit thick. Japan has no plans to acquire the long-range strike aircraft, missiles, or offensive naval forces of a conventional great power. Nuclear weapons are pro­scribed. But Kissinger was right about the determination with which Japan would pursue its modest goals. The 1986-90 Mid-Term De­fense Program projected spending of $132 billion (at prevailing ex­change rates in 1987); it has been fully funded in each of its first four years, and the same is virtually cer­tain in 1990. Spending will top $31 billion in 1989.

With one year left in the MTDP, notes a recent Pentagon report, Ja­pan has now achieved eighty-eight percent of its goal for tanks, eighty-two percent for artillery, eighty- nine percent for destroyers, eighty percent for submarines, seventy-five percent for interceptors, and 100 percent for transports.

Nowhere is the impact of the Jap­anese effort more apparent than in the 45,000-strong air force.

The Japanese Air Self-Defense Force (ASDF), with 340 front-line combat aircraft, can put aloft more planes than the US has permanently based in the Far East. By the end of 1990, Japan will deploy 400 war­planes in ten interceptor squadrons, three fighter-support squadrons, and other units.

Today, nine squadrons of US-designed, Japanese-built F-15s and F-4Es form the backbone of Japan’s air defense interceptor force. In a crisis, the ASDF could call on 130 new F-15DJ jets and another 129 F-4EJ Phantom II planes. These forces are armed with AIM-7 Spar­row III and AIM-9 Sidewinder mis­siles.

Plans call for Japan to form a tenth full fighter squadron by 1993 with new-production F-15s.

Today, most ASDF missions en­tail intercepting Soviet fighters and reconnaissance aircraft entering Japanese airspace to the north of the island of Hokkaido. Japan confronts several hundred of these intrusions each year.

In war, Japan’s air force would also be charged with providing sup­port to ground and naval forces. The mainstay of the interdiction mission today is the fleet of about seventy-five Japanese-built F-1 fighter-bombers, organized into three squad­rons. These are armed with Japan’s Type-89 air-to-surface missile and with conventional ordnance.

A World-Class Fighter

The F-1 force is a weakness. Thus, two years ago, the US and Japan announced plans to jointly develop a new support fighter in a project to cost more than $8.2 bil­lion, based on a projected produc­tion run of at least 130 planes. The fighter, known in the US as the FSX and in Japan as the SX-3, is to be based on the General Dynamics F-16, but with heavy infusions of Japanese technology.

Under current plans, a prototype of the SX-3, expected to be one of the world’s finest fighters, will fly in 1993. The ASDF will organize a new wing to operate the SX-3. The first squadron will be in place in 1998, with two more to come soon after.

The ASDF is undergoing a mod­ernization program to improve its reconnaissance and early warning capabilities. Today, Japan’s recon­naissance mission is based on the fourteen-plane squadron of RF-4EJ planes. The fleet is scheduled to get upgraded reconnaissance packages. The first prototype is to reach op­erational status next year. ASDF’s fleet of eight E-2C Hawkeye air­borne early warning craft will ex­pand to ten by 1991.

Japan’s navy, the Maritime Self-Defense Force, has come far.

In a crisis, Tokyo would rely on the 44,000 men of the Japanese fleet to keep open critical sea-lanes or to blunt seaborne attack. Five regional naval commands defend specific geographic areas. A high-seas fleet would operate further from home.

Already, the MSDF could go to sea with fourteen attack sub­marines, fifty destroyers, seventeen frigates, forty-six amphibious craft of various sizes, thirty-seven mine-warfare ships, and fourteen small patrol combatants. The MSDF op­erates about 100 support, training, and survey ships.

By 1991, Japan plans to reach its goal of deploying sixty destroyers—twice the number in the US Seventh Fleet, which operates across the en­tire western Pacific. The attack-sub­marine fleet will probably level off at sixteen or seventeen boats when the program is complete. Some 100 P-3C Orion submarine-hunter air­craft, assembled in Japan by Ka­wasaki Heavy Industries, will be flying.

For antiair warfare, Japan is to build at least three, and perhaps four, destroyers outfitted with the US-developed, ultrahigh-capacity AEGIS air-defense system. The first of the class will be launched in 1991. The ships will greatly strengthen fleet defense against missile and aircraft attack.

Japan’s ability to wage antisub­marine warfare against Soviet un­dersea craft will improve. Aging Japanese Uzushio-class boats are being replaced with Yushio- and Improved Yushio-class subma­rines. Japan wants a sophisticated sonic depth-finder vessel for ASW. Also on tap: more and better equip­ment useful in tracking USSR naval movements, plus new ASW heli­copters.

Japanese Landpower

Less conspicuous but no less im­portant has been Japan’s modest up­grading of its army, referred to as the Ground Self-Defense Force, or GSDE

Goals that will soon be met in­clude deployment to specific re­gions of twelve active divisions, with between 7,000 and 9,000 troops each, and three composite brigades; one armored division and additional armored, helicopter, and airborne brigades for mobile warfare; and eight antiaircraft artillery groups.

The Army, responsible for ground combat, amphibious land­ings, some ground-based air de­fense, and close air support, stands at only 156,000 troops, below the authorized level of 180,000. Even so, Japan’s Army has embarked on several weapon-update programs to be completed in the 1990s.

Foreign acquisitions include the American Patriot air-defense SAM system and the US 227-mm Multi­ple Launch Rocket System.

Japan plans to produce Type-90 THX main battle tanks to replace its aging inventory of Japanese Type-61 models. The GSDF’s units possess a total of nearly 1,200 main battle tanks, half of them Type-61s, and 700 armored vehicles of all classes.

Overall, notes a recent General Accounting Office assessment, Ja­pan is now close to meeting all its defense goals. There is progress in lower-profile areas, such as more coordination between the various services. US military officers ap­plaud Japan for coming so far in a short time.

Says one Pentagon study: “Japan is making rapid progress towards the military capability to fulfill its agreed mission—i.e., the defense of its territory, including air and sea lanes to an offshore distance of 1,000 nautical miles.”

No one, however, thinks even that limited task would be easy. Soviet forces also have improved. Adm. Huntington Hardisty, US Pacific Commander, points out that in the past four years Moscow has de­ployed to the Pacific advanced Akula submarines, MiG-31 fighters, and long-range bombers with cruise missiles.

With an 8,485-mile coastline, Ja­pan naturally focuses its attention on maritime and coastal defense op­erations. Heavy concentrations of Soviet airpower around Vladivos­tok make air defense an additional concern.

Japanese forces would be called on to repel a limited assault on the home islands. Japan would also face the tasks of combating Soviet sub­marines and airpower in its vicinity and monitoring the passage of Sovi­et submarines and other warships through straits connecting the Sea of Japan with open ocean.

For all its improvement, say ana­lysts, the GSDF’s ability to under­take such sustained combat leaves much to be desired.

Radars and vital air bases, for ex­ample, still go undefended. The Air Force, lacking refueling capabili­ties, can’t provide air defense cover or strike support for ships at more than moderate distances. Day-to-day readiness and combat sus­tainability are problematic. Surviv­ability of critical installations is doubtful. Command control and communications would be tenuous at best.

Such weaknesses presumably will be addressed in Japan’s next de­fense plan, covering the years 1991­95 and due next fall. The Japan De­fense Agency already has begun work on it. The government has af­firmed its intent to seek long-term real growth in funding.

The Pentagon maintains that it is important that the next defense plan continue improvements in air defense, anti-invasion and antisub­marine warfare, and C31 capabili­ties, as well as combat sustainability and infrastructure.

Japan evidently will do so. The GAO investigation of the Japanese program reports that Tokyo is giving serious thought to acquiring an over-the-horizon radar system, three to four new squadrons of inter­ceptors, eighteen to twenty refuel­ing aircraft, twelve to sixteen long-range early warning aircraft, and fif­teen to twenty large air transports, plus readiness improvements.

“The Minimum Necessary”

Japanese politicians, however, will face some hard questions. One of the most important, Japanese ob­servers maintain, will be whether to set a new force goal for the SDF. Some believe that a larger military is in order, but any move in that direc­tion is sure to cause a political up­roar.

Another major question concerns extending the range of Japan’s air­craft. Building a modest refueling capability is one option. Tokyo is also evaluating the use of small air­craft carriers with updated AV-8B Harrier II jump jets on board. Ei­ther scheme could run afoul of do­mestic politics. To many in Japan, range-extension would make the aircraft “offensive” military equip­ment, prohibited by Japan’s pacifist constitution.

Domestic opinion is not the only constraint. Japan must satisfy its Asian neighbors—in particular, China, South Korea, and the na­tions of Southeast Asia—that its power will remain nonthreatening.

Some nations worry that Japan is on the road to becoming a military power again, despite Pentagon as­surances that “Japan is still doing the minimum necessary to meet its defense goals, goals which are clearly limited.”

Japan openly professes, in fact, that US military power remains and will continue to remain the ultimate guarantor of its national survival. Prime Minister Toshiki Kaifu, on his recent visit to Washington, em­phasized the need to “ensure the effective operation of US-Japan se­curity arrangements.”

A Pentagon report is more direct: “The Japanese force structure re­quires the presence of complemen­tary US forces to remain viable.”

The American presence in and around Japan is substantial, about 65,000 US troops on Japanese territory or waters. The largest seg­ment, a 38,000-man Marine Expedi­tionary Force, is based on the island of Okinawa. USAF maintains in Ja­pan some 16,200 personnel and three squadrons of F-15C/Ds, two squadrons of F-16s, and eighteen of RF-4Cs. The Navy has a major presence in the Western Pacific and a major facility at Yokusuka.

In recent years, cooperation be­tween US and Japanese forces has improved markedly. Japanese naval forces, for example, now exercise with Pacific Fleet and other friendly Pacific navies.

A Sense of Grievance

Even so, the Tokyo-Washington relationship is becoming a troubled one, for reasons that have more to do with domestic politics and econ­omies than with security matters.

The most fundamental problem causing friction between the two al­lies is the lopsided economic rela­tionship between Japan, the world’s biggest creditor nation, and the US, the largest debtor. Last year, Japan’s trade surplus with the US fell by $8 billion, but it still came to $52 bil­lion.

In addition, Americans and Japa­nese alike have been wounded by bitter disputes over technology ex­ports. On the US side, Americans felt betrayed when it was revealed that Toshiba Corp. illegally sold the Soviet Union sensitive milling tech­nology, which was then used to manufacture quiet propellers for Soviet nuclear attack submarines.

Japan’s sense of grievance was fueled by the Bush Administration’s reopening and modification of the US-Japan SX-3 agreement after Tokyo thought a deal had been struck. Japan believed it was being made into a scapegoat for US eco­nomic weakness and mismanage­ment.

Compounding the tensions is an increasingly sharp dispute over “burden-sharing.” Japan resents congressional charges that it is shirking its defense obligations. Tokyo points out that it no longer holds defense expenditures below one percent of its gross national product, as it did officially for ten years. It points to the fact that Japan now has the third largest defense budget in the world, surpassed only by the two superpowers. $45,000 per American

Host-nation support for US bases and troops in Japan is higher than ever. When all factors are consid­ered, says Tokyo, it contributes the equivalent of $2.7 billion annually to upkeep of American forces based in Japan. That works out to about $45,000 per US serviceman.

Many members of Congress re­main distinctly unimpressed by these arguments. They note that, though the one-percent limit no lon­ger is official policy, defense bud­gets remain only slightly above that level. The US outlay is closer to six percent of GNP. They add that much of the growth in Japan’s arms spending, calculated in US dollars, stems not from new commitments but from the spectacular rise in val­ue of the yen compared to the per­formance of the US dollar.

“The Japanese have a long way to go on the burden-sharing front,” charges Rep. Pat Schroeder, a Colo­rado Democrat who sits on the House Armed Services Committee. “Their support of US forces in Ja­pan is generous, but considering they only spend one percent of their [GNP] on defense, they can afford to be much more generous.”

A recently completed Defense Department report on burden-shar­ing supports Schroeder’s charge. In its analysis of the defense perfor­mances of the US, Japan, and Amer­ica’s NATO allies, Japan receives the lowest possible rating in six of the nine areas in which it can be judged. West Germany, by compari­son, rates high or highest in eight of fourteen areas in which it can be judged and medium in another three.

GNP per capita in Japan is $19,500, compared to that in the US of $18,200. Even so, the average Japanese spends only $200 on de­fense, vs. $1,200 for the average American.

Congress voted overwhelmingly in 1987 to urge Japan to triple de­fense spending to three percent of GNP. The question is where Tokyo would spend it all. Richard Armi­tage, the former Assistant Secre­tary of Defense for International Se­curity Affairs, estimated that Japan could buy everything on its wish list for the equivalent of two percent of its GNP. A significantly higher level of spending, he implied, would transform Japan into a truly formi­dable military power.

Japan’s military effort has made strong progress against heavy odds. The trick for Tokyo now will be to navigate between the insistent de­mands of a superpower patron and the dangers of military excess.
