"The Japan Maritime Self-Defense Force?s (JMSDF) fixed-wing patrol aircraft force?s structure
comprised of ?100 P-3C Patrol aircraft-based Structure? has been a symbol of modernization of
Japan?s maritime defense capabilities since the 1980s along with the escort flotilla?s ?Eight Destroyers
with Eight Helicopters Concept?. However, this concept has not been systematically researched in
terms of the background and purpose of its formulation as well as its significance for Japan?s maritime
defense. I, the author, published research results related to the ?Eight Destroyers with Eight Helicopters
Concept?, which utilizes oral history material and other data, in the National Institute for Defense
Studies? (NIDS) Military History Studies Annual Report last fiscal year. Therefore, in this article here,
I look back on the background and other aspects of the ?100 P-3C Patrol aircraft-based Structure?
from the same perspective and using the same methods as the ones used for the article on the ?Eight
Destroyers with Eight Helicopters Concept? and reviews its significance in Japan?s defense force. "
