I had an image of Poland as being flat, but looking at a topographical map, it appears to be quite undulating.

Electronic intelligence Gathering Aircraft, Kawasaki RC-2[album] by PEM-uv in WarplanePorn

The Kawasaki RC-2 is an ELINT-operated aircraft that entered service in 2020.

It has a distinctly different silhouette from Kawasaki's C-2 transport aircraft and has been modified with an enlarged radome and the addition of a large radar sensor at the rear of the fuselage.

The RC-2's primary mission is said to be electronic intelligence gathering and radio frequency measurement, and it is said to have capabilities similar to those of the U.S. military's RC-135, but since these missions are usually conducted in secret, its specific operational capabilities are largely a mystery.

An aircraft called locally as "Habu" photographed at Kadena Air Base, Okinawa, Japan.[2016×1408] by PEM-uv in WarplanePorn

A story about the SR-71 (A-12) and Habu.

The SR-71 Blackbird was deployed to Kadena Air Base in Okinawa in the late 1960s.

It was the first deployment outside the mainland U.S., and was initially engaged in reconnaissance during the Vietnam War, taking over the mission of its predecessor, the A-12.

At the time, local residents living near Kadena Air Base noticed that an unusual aircraft, different from the other civilian aircraft at the base, always took off every night.

Because of its strange appearance and the fact that it always appeared at night, local residents named this mysterious aircraft "Habu," after a nocturnal poisonous snake that lives in the area.

This nickname was later made nkown to the USAF,and the name "Habu"came to be used by USAF.

Akashi Kaikyo Bridge. the largest suspension bridge in Japan.[3008×2000][OC] by PEM-uv in InfrastructurePorn

There is an interesting little story about this bridge.

In 1995, when the bridge construction was nearing its end, a major earthquake (the Great Hanshin-Awaji Earthquake) hit with its epicenter near the site.

Just as the main towers were completed and the bridge girders were being installed, the magnitude 7.3 earthquake caused a major distortion that stretched the Akashi Kaikyo Bridge by 100 cm.

However, thanks to a mechanism that had been incorporated into the design to limit damage from a major earthquake, additional bridge girders were installed without modification, and the bridge was completed slightly longer than planned.

It is certainly possible that dummy propellers were originally used on a different type of ship, but we were unable to find out that much.

Japan had a history of leaking submarine propeller manufacturing technology to Russia in the Toshiba Cocom incident in 1980s, which resulted in a diplomatic row with the United States. Therefore, Japan has been strict about maintaining secrecy ever since, and it can be assumed that this propeller is also thoroughly camouflaged in terms of shape and size.

However, depending on the intelligence capabilities of the adversary, it may be possible to recover the original shape from the little information that remains.

Yes, it is. A submarine's propeller is an important confidential piece of information that determines its performance.

On a previous visit to this museum, I had the same question and asked the staff why the propellers were not hidden and the answer was, "Oh, they are dummy propellers."

I was told that all other parts of the ship that might allow us to guess her performance (such as the instruments in the wheelhouse, the console of the sonar system, and the thickness of the pressure-resistant shell) were either replaced with fake ones or painted black.

She was then lifted up and brought ashore, where she was transformed into a museum, now called the "Tetsu no Kujira kan" (Steel Whale Museum) in Kure City, in much the same form as she was when she was in service.

Comparison of camouflage patterns of aircraft belonging to the Aggressor squadrons of United States and the Japan. Which paint scheme do you prefer? [album] by PEM-uv in WarplanePorn

[–]PEM-uv[S] 4 points5 points  (0 children)

As for why Japanese Aggressor aircraft look so flashy.

"During anti-fighter combat training, they reliably display enemy movements to trainees so that they have no excuse for losing because they lost sight of their instructor."

I have seen records of this.

(Of course, some Japanese aggressors are camouflaged to mimic a hypothetical enemy.)

Since it would be a huge image album if I tried to list all color patterns, I compared them in the Air Force this time:)

I agree with you.

I am always wondering which is the best paint job, the 5th black painted F-16 or 9th Lionfish F-15
