This is the second Iranian stealth cruise missile, which I ignored yesterday, but was then pointed out by a friend.
In any case, it appears that Iran is starting to take its cruise missile program more seriously, with an increasing focus on incorporating low-profile design features into its new missiles.
However, a more accurate technical assessment would require more information about the missile's radar cross section (RCS) and the radar-absorbing materials (RAM) used in its airframe.
