So lets get this straight...despite the fact that Storm Shadow is 20 years younger,
TACTOM is essentially a new missile, and the fact that it doesn't drastically outperform the legacy variants is a clue here. Just being younger doesn't automatically make a missile better. You'll have to argue explicitly where all the progress went to have a valid point. Where is the new tech?
is the same size as Tomahawk,
Fair enough.
What's that supposed to even mean? Lift = weight, and since they're the same size (taking that as mass, which is what matters here), as you correctly point out, they are the same in this regard too?
Duplicate of argument #1
near exact warhead size...
Yeah, which is what makes argument #1 valid at all.
it somehow is totally unable to get 50% of the range of the Tomahawk...
Yes. In these low pressure ratio, low-thermal efficiency engines the benefit of having a turbofan (Tomahawk) over a turbojet (StormShadow) is hard to overstate.
even though it gets a bit of a boost from air launch...?
Tomahawk gets a bit of a boost from... a booster.
Must be some sort of 'magic' in the Tomahawk I guess....
Nope, just a much more efficient engine and lower cruise speed (to get a sense of the impact of that, compare the range at high-speed cruise vs. economical cruise Mach in a business jet, and consider that the speed difference between StormShadow and Tomahawk is substantially greater).
Although I'd be interested in seeing a lower heating value for the T-H dimer fuel in Tomahawk (I did look, but no dice)... seems it was more about insensitive storage properties than increased energy density, but still.
Black Shaheens payload is not within the MTCR critera, being less than 500kg....MTCR is also voluntary, its not an arms control agreement...
MCTR limits both range and payload. Which is why the export Iskander-E for example has a 480kg warhead AND sub-300km range. It's not either/or, but both.
To quote the US State Dept...
"The Missile Technology Control Regime (MTCR) is an informal political understanding among states that seek to limit the proliferation of missiles and missile technology."
So are you going to take non-proliferation seriously or not? I'll remind you next time the outrage runs high when a regime in less favourable esteem tries to get away with giving the international community "informal assurances" that they won't do X or Y. Until all of a sudden they decide it is opportune to do just that after all...
It's main aim is Dual Use technology transfers to nations with WMD programmes...the UAE didn't qualify in that regard...
It is supposed to tackle the delivery vehicle end of the WMD problem. Whether it applies or not does not depend on the recipient in question actually having an active WMD programme. Third-party transfer, etc.
