@Gautam
I think you are right and I got it wrong initially
I followed up with the air water missile thing , and later realised that the yellow model on the left is not that.
It is most probably what you claimed could be in the first place , a model of a new SSBN
If one takes the front portion of model as the front portion of a SSBN , then the slant appendages are the fore fins. While the hump on the model is the section containing the SLBM silos . While the extended portion before the hump is the conning tower aka mast .
