Was there “accessibility” between the Collins submarine design office and the legacy systems design office ?

Does it seem there was “accessibility” between the Collins submarine design office and the legacy systems design office ?

The book “Collins Class Submarine Story: Steel, Spies and Spin” suggests the legacy system was successful.
So it looks like the legacy system was a working model.

But there can be hiccups.

Ryle(1900-1976) argued in his paper “Systematically misleading expressions” (1932) that some quite ordinary forms of expression are ‘improper’ to the states of affairs they record, invite thereby misassimilation to other forms of expression, and so tend to generate complexity, even flat nonsense, from which it is the bisiness of philosophical argument to rescue us.

Lament for Seville, by Abu al-Baqa’ al-Rundi,1267, says (in translation) that “Everything declines after reaching perfection, therefore let no man be beguiled by the sweetness of a pleasant life”.

Murphy’s law cautions us that whatever can go wrong will go wrong.

There is, ” …a danger inherent in all secretive societies for their cellular form devised by the founders for the security of the movement, can as readily be used to ‘hoodwink’ the leadership, who thus become unwitting ‘front men’ for activities they would never countenance.” [from Stephen Knight's "Chinaman" report.]

It seem that something must have been impeding the project BEFORE Bob Clark, Operational Software Manager, SWSC, project and DMO.(see “Steel, Spies and Spin”)

Clark would have assisted to the extent that he could.
Clark would have done what he could, but the “damage to the project might have been too severe”.

All sorts of things might have happened.

Flat nonsense, masquerading as authentic legacy algorithms, might have been issued to the new design office.
Legacy algorithms supposedly “shrink wrapped” would be able to have been doctored, and simulators would also be able to have been doctored, unless there was special encryption technology to foil counterfeiting.
