Now, regarding bypassing the SUBTICS CMS, well, that's impossible because GPS gives only locational coordinates. For any weapons launch, one requires a direct connection to the inertial navigation system using ring laser gyros. And this RLG-INS is integrated with the SUBTICS & cannot be bypassed. Even if a standalone RLG-INS is used only for weapons release, how will this RLG-INS interface & synchronise with the RLG-INS of SUBTICS? So, without such data on the stabilisation of the platform (submarine), it is impossible to adjust the horizontal/vertical attitude of the missile-launch fire-control system & without this any data pertaining to the horizontal/vertical attitude of the SLCM cannot be uploaded on to the SLCM's on-board RLG-INS & mission computer. Therefore, it is physically impossible to bypass the closed-loop fire-control sequence that always begins at the CMS (SUBTICS in this case) & no miracles happen in this domain.
Why is the standalone system required to interface with SUBTICS? You can carry any INS on a submarine and interface it with the missile.
I'd judge based on the content, not the title.
The key question in the article is:
Bypassing SUBTICS Combat-Management System on Agosta SSKs. Even India ran into problems wrt torpedo choice for IN Scorpenes because we had to choose from only those HWTs that were already integrated with SUBTICS (like BlackShark or F21), a new torpedo would require extensive re-writing of the CMS which would take too long & cost too much...and certainly cannot be done by anyone not certified by the OEM. At least not if you want to retain an ounce of credibility after that. There is no way a nuclear-capable guided cruise missile can be integrated with SUBTICS without probably violating a whole lot of End-User agreements.
As explained by other posters, ejecting any object from the submarine has already been achieved. Said object doesn't have to interface with the CMS. The target can be hardcoded into the missile for test purposes.
