Actually the Israeli Dolphin submarines have had this capability for some time.... the iceing on the cake would be to have Babur cruise missiles launch from SSK with nuclear capability, that would be a first!
The 1st three Dolphins were specifially built as heavily modified German Type 209 subs, in fact so modified that they are not even included as a Type 209 sub-class but are a clss of their own. The second three are heavily modified German Type 212 subs (12 meters longer and 500 tons heavier) with Air Indeppendent proulsion (AIP), again, being in a class of their own as Dolphin IIs. In both cases longer submarines with heavier displacement.
These subs also added four, large 650mm firing tubes in addition to the six normal 533mm tubes. Many feel these larger tubes were added specifically to enable the launch of SLCMs.
It is widely believed that the Israeli subs arein fact equiped to carry and fire both conventional and nuclear SLCMs. In fact the US Navy monitored a test of one of the Dolphins firing 1,500 km missiles in the Indian Ocean in May of 2000. Two missiles were launched. So it is clear that they do in fact have this capability.
The first three Dolphins (heavily modified Type 209 design) were commissioned in 1999-2000. The fourth and fifth vessels (heavily modified Type 212 Design) were delivered to the Israeli Navy in 2012 and 2013. One is already commisisoned and the second is to be commissioned in 2014. One more is being built.
