Som likely usefull if drveloped as local version of tomahaowk or scalp launch from subs or surface ship
Som’s shape and being specially developed for aircraft launched mission parameters , will not allow it to be further developed in to a tomahawk style missile.
Scalp (storm shadow) however is a similar missile. It is heavier larger and has longer range. It utilises a bigger jet engine. SOM’s next stage could be a missile like Scalp. But I think my money is on a supersonic cruise missile being in the works!
Current development work being carried out on SOM is the C series. A and B series are, HE and concrete buster versions. C series will be for moving sea targets. There is a SOM-J version which is smaller and good for moving sea targets and can be fitted in to the internal port of f35. SomJ will also be launched by Akinci drone.
Atmaca is the one that can hit be further developed as a cruise missile. There is however a program in the works called Gezgin . This is going to be a 800-1500km range subsonic cruise missile.
