After reading yesterday's post about this missile, I did a quick Google search, and in the first page of results, I found various stories that described this Sizzler missile either as subsonic (and looking much like a Tomahawk), supersonic, or subsonic with a supersonic terminal phase. And we're talking about reputable sites, such as Jane's, with varying information.
I hope the Navy has a better idea of what it's up against than this.
Nope-there are around 5 variants in this missile family-something like 2 land attack variants(subsonic),1 anti-sub & 1 anti-ship variant with a range of 220 kms with a supersonic terminal stage.All of these look very similar to the Tomahawk & hence can be deployed from modified torpedo tubes of the Kilo class boats(India & China) or vertical launch tubes from Frigates(Indian navy).
