A comparison of emergency scramble numbers between Reiwa 3rd and Reiwa 4th years.

A comparison of emergency scrambles conducted by the Air Self-Defense Force in the Reiwa 4th and Reiwa 3rd fiscal years reveals distinct trends:

Total Counts:
Reiwa 4th year: 778 scrambles
Reiwa 3rd year: 1,004 scrambles
The Reiwa 3rd year had a higher number of emergency scrambles.

Country/Region Breakdown:
Both years witnessed Russia and China causing the most emergency scrambles. In the Reiwa 4th year, Russia recorded 150 and China 575 scrambles, while in the Reiwa 3rd year, Russia had 266 and China 722 scrambles. Other countries/regions accounted for 53 scrambles in Reiwa 4th and 13 scrambles in Reiwa 3rd.

Emergency scrambles originating from Taiwan and North Korea were limited in both years.

Regional Air Command Breakdown:
In the Reiwa 4th year, the Southwestern Air Command executed 515 emergency scrambles, surpassing other commands. Similarly, in the Reiwa 3rd year, the Southwestern Air Command led with 652 scrambles.

While the emergency scramble counts for the Central and Western Air Commands were similar in both years, the Northern Air Command’s performance varied.

This comparison provides insights into how the Air Self-Defense Force’s emergency scramble achievements have shifted annually, delineated by country/region and regional air commands.

Annual Disaster Dispatch Records by the Self-Defense Forces

“Detailing the annual records of Self-Defense Forces’ disaster dispatches and unexploded ordnance disposal, including specific data such as the nature of dispatched aid, affected regions, and the count and types of unexploded ordnance disposed of.

The number of disaster dispatches has fluctuated over the past few years. In the fiscal year of Reiwa 4, 381 disaster dispatches were carried out, slightly lower than the 383 dispatches in the preceding Reiwa 3. Further back, in Reiwa 2, there were 531 dispatches, while in the fiscal years of Heisei 31 and Reiwa 1, 449 dispatches were made. These figures indicate the variability of dispatches, likely influenced by changing disaster demands and circumstances.

Even during the Heisei era, disaster dispatches were consistently conducted. There were notably high numbers in Heisei 18 and 17, recording 812 and 892 dispatches, respectively. However, from Heisei 20 onwards, the numbers ranged between 606 and 679. Across the late Heisei and early Reiwa periods, while fluctuations in dispatch counts occurred, the sustained engagement of the Self-Defense Forces in emergency disaster relief activities remained evident.”
