Did instances of "limited hangout" occur during the Collins submarine project ?

Question

<<Limited hangout

From Wikipedia, the free encyclopedia

A limited hangout is a form of deception, misdirection, or coverup often associated with intelligence agencies involving a release or "mea culpa" type of confession of only part of a set of previously hidden sensitive information, that establishes credibility for the one releasing the information who by the very act of confession appears to be "coming clean" and acting with integrity; but in actuality by withholding key facts is protecting a deeper crime and those who could be exposed if the whole truth came out. In effect, if an array of offenses or misdeeds is suspected, this confession admits to a lesser offense while covering up the greater ones.>>
