Was a key algorithm doctored by rogue staff ?

Question

We kept reading in the media that there were "problems" with Collins submarine software "integration". It doesn't wash. Each algorithm would be vetted by an original equipment manufacturer before being approved for use in the system.

The only possible explanation is that an algorithm, already approved, was doctored by rogue staff.

"men are so simple, and so subject to present necessities, that he who seeks to deceive will always find someone who will allow himself to be deceived. One recent example I cannot pass over in silence. Alexander VI did nothing else but deceive men, nor ever thought of doing otherwise, and he always found victims; for there never was a man who had greater power in asserting, or who with greater oaths would affirm a thing, yet would observe it less; nevertheless his deceits always succeeded according to his wishes, because he well understood this side of mankind."

(machiavelli, the prince, ch 18, para. 21)

“Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth.”
