There's a security scandal underway concerning the French manufacturer of the stealth submarine, Scorpene. The Australians, who recently ordered similar boats, are particularly vexed. From The Australian:
There is almost no breach of national security more serious than the disclosure of the stealth secrets of a country’s submarine fleet.
A submarine is only as effective as the secrets it keeps. If an enemy knows those secrets, the game is over. As the old wartime saying goes, “loose lips sink ships.”
That is why Australia should be deeply concerned by the Snowden-style leak of 22,400 secret documents written by the same French shipbuilder, DCNS, that will design Australia’s future submarine fleet.
The leaked DCNS documents describe in excruciating detail — line by line and bolt by bolt — the entire combat abilities of India’s new six-boat Scorpene submarine fleet. It has dealt a hammer blow to India’s national security and it begs the question; if it has happened to India, why couldn’t it happen to us?
Australia cannot afford to spend $50 billion on the biggest defence project in the nation’s history only to have it potentially compromised by sloppy security about confidential information.
Hmmm, sloppy security. Serious business. But not when it comes to another amazing bit of stealth warfighting gear, the Lockheed F-35 joint strike fighter.
Someone (everybody knows it's China) had a field day hacking Lockheed and British Aerospace computers downloading (stealing) massive amounts of data (secrets) and millions of lines of computer code (stealth operating system) of the F-35. Then Iran managed to hack a Lockheed RQ-170 super secret stealth drone, bringing it in for a crash landing. Chinese aerospace types didn't waste any time getting to Tehran. They scoured the drone for Lockheed's stealth secrets - shaping, materials, coatings and such and they went home with plenty of parting gifts, mainly the drone's electronic wizardry.
The hacks and the RQ-170 capture caused a big kerfuffle for a while but then the noise went silent and nobody has had much to say about it since. It's as though a blanket was thrown over it. After all the F-35, like American banks, is too big to fail.
The Australians are grappling with a legitimate security concern in the French sub leaks. It's a good thing, F-35 customers don't seem to care.
