The Japan Air Self-Defense Force (JASDF) is built largely around available American types including the F-4, F-15, and F-16 fighter lines.



POWER INDEX SCORE

60.9

(Ranked 9 of 53)
*See Notes
Japan's strategic place on the globe (in regards to global trade and potential threats from China and North Korea) forces it to operate a fairly impressive air arm (under the banner of the Japan Air Self-Defense Force = JASDF) within the confines of its post-World War 2 constitution. Its fighter fleet is made up largely of classic American Cold War types - the F-4 'Phantom II' and F-15 'Eagle' fighters - while the F-2A exists as a local Japanese interpretation of the successful F-16 'Fighting Falcon' line. However, the fleet received a shot in the arm with the arrival of the first nine Lockheed Martin F-35A 5th Generation strike fighters (of which one has since been lost to accident).

Beyond this is a traditional focus on a rotorcraft force (making up 8% of inventory) and transport (5%) - of which some of the latter are of local design, development, and production (including the C-2 set to arrive in greater numbers). Like other modern air services, the JASDF has a large training contingent led by the locally-built T-4 Advanced Jet Trainer and backed by the homegrown T-3 for basic training duties. Training (twin-seat) derivatives of frontline fighters are also on hand.

1% of total inventory is made up of aerial tankers while 6% mark various special-missions platforms. Other roles are fulfilled by the considerable American presence in the region which has the added benefit of providing a high-profile deterrence to potential enemies.
NOTES: The WDMMA.org Power Index (PwrIndx) score looks at various qualities of an individual air power (or service branch). While total aircraft certainly influences the rating, aircraft variety (force balance) also plays a key role in determining an air service's placement on the list. Other focused qualities include local industry (aerospace-related) capability, future outlook, and current/recent combat experience. All this is worked into a formula which provides an analytical approach to resolving a force's fighting state in the modern world. This approach to fighting strength is highly theoretical and does not take into account a nation's available manpower or resolve in the face of conflict nor does it involve land and naval fighting strength. The top achievable PwrIndx score belongs to the United States Air Force with its rating of 242.9. As of now, UAV systems are not taken into account due to reporting differences between publicly-available sources (these will be integrated as some point). Navy aviation branches do not take into account the fighting capacity of naval ships.
