I thought the Shipwreck was an anti-ship cruise missile, while the BrahMos can be used as a cruise missile targeted at land targets too? I thought that's the reason they are making the distinction that the BrahMos is the world's first supersonic submarine launched cruise missile, even though supersonic submarine launched
anti-ship cruise missiles have existed for years. So have supersonic cruise missiles (e.g. various families of supersonic air-launched cruise missiles), but I cannot recall a supersonic submarine-launched cruise missile. I could be mistaken, but I thought the anti-ship cruise missile vs cruise missile was the main difference, and if that's the case, then the BrahMos is the world's first supersonic submarine launched cruise missile.
Again, I may have understood the article incorrectly, but that's what I gleaned from it.
I also know in the past there is one case (by India btw) where they used an anti-ship cruise missile (the Styx) as a jury-rigged land-attack cruise missile (when the Styx was used against Pakistani naval base, taking out facilities that directly or indirectly took out most of the Pakistani navy during that war). Thus, I am sure an (for example) Oniks could be jury-rigged into a land-attack cruise missile. But I still think, maybe incorrectly, that the BrahMos is the first submarine-launched, supersonic, cruise missile.
You are likely correct. I was very fixated on the Sunburn back then, working on efforts to develop an aerial target to simulate it. The LTV candidate actually looked a lot like it, with cruciform intake.
Seems the Russians could have developed a ground attack version had they wanted to. But the supersonic capability is not nearly so desirable as in ship attack, and they had plenty of subsonic cruise stuff.
The flexibility of the Brahmos is impressive if it all works. Not sure how cost effective it is though.
