I could be wrong, but aren't Scuds powered by a mix of

nitric acid? Which, again subject to error, powers the booster for the
SA-2 missile in widespread use in Iraq? (I'm sure both use red fuming
nitric acid as oxidiser - kerosene is hardly a classified agent and
hydrazine is widely used too)

The Iraqis were still allowed to use rocket-powered weapons,
just with
limitations.

I'm not familiar with the fuel used by either the Scud or the SA-2,
so I can't comment on whether the fuel is common to both types or
not. Kay did state in his report, however, that the fuel is
usable only by the Scud.

Reading his report, he refers only to red fuming nitric acid in the
unclassified public part. A search for "hydrazine" (the fuel, as opposed
to the oxidiser, for the Scud family) came up blank. So he's got Scud
_oxidiser_. (A small technical quibble, but us engineers are pedantic)

RFNA is indeed usable to power Scuds and derivatives... but it's also
used as oxidiser in Styx/Silkworm antiship missiles, which Iraq was
allowed to retain, and for SA-2 Guideline SAMs which again were
permitted - both use kerosene fuel with RFNA oxidiser. (Easy to forget
that Iraq wasn't being completely disarmed, just stripped of long-range
offensive weapons)

RFNA is one of those awkward "precursor" chemicals, like ammonium
nitrate; it's useful for a lot of tasks, one of which is powering Scuds;
but it can be used in other missiles, and it's necessary for a lot of
manufacturing tasks too.

If you find a stash of ammonium nitrate, the owner might intend to use
it to fertilise his fields. Or he might be quarrying for gravel. Or he
might be a terrorist about to build a huge truck bomb. All are
_possible_, only one is blatantly illegal. RFNA is crudely similar.


Doesn't prove Saddam was an angel of sweetness and light, but it's not
convincing that he was busy building ICBMs either. He'd need RFNA just
to make Kalashnikov ammunition, and he was allowed _that_ (and needed
it... Iraq still has hostile neighbours)

Hope this was at least somewhat helpful Paul. Take care

You too.
