The Defense Ministry plans to slash its tank forces by more than half and redeploy the remaining vehicles to Hokkaido and Kyushu to meet the realities of the post-Cold War world, sources said.
The number of Ground Self-Defense Force tanks will be reduced from the current 741 to 300 within 10 years, they said.
The proposal to reduce tank numbers will be included in the new National Defense Program Guidelines, the government’s basic 10-year plan for defense and national security, scheduled for completion in mid-December.
During the Cold War, the Self-Defense Forces put top priority on preventing an invasion by the Soviet Union with its large armored units. The Defense Ministry plans to shift its emphasis from the defense of the mainland to the protection of remote islands, with China’s growing naval capabilities in mind.
After all tank regiments are withdrawn from Honshu, the SDF will deploy high-speed, highly maneuverable, lightweight armored vehicles to Honshu in their place.
Armed with 105-millimeter cannons, the same caliber as that of standard tanks, the eight-wheeled maneuver combat vehicles can reach speeds of 100 kph. In addition, the vehicles are light enough to be transported aboard C-2 aircraft, allowing the SDF to deploy them to threatened islands more quickly.
Ordinarily I'd be up in arms about a reduction in the number of armored vehicles in any army, but in this case it makes perfect sense.
First, they're not giving up the firepower and shock effect of a heavy cannon. Second, they're a VERY highly urbanized country. Wheeled vehicles will be able to respond much better to enemy actions, without paying the penalty of having to survey roads and bridges to get them to the scene.
I do have an argument with the idea that transporting armored vehicles by aircraft is a reasonable approach but I think that might be more selling point than actual wartime utility (at least I hope so).
All in all I think the Japanese are taking the threat of future combat very seriously and are adapting their forces to face the future threat.
