From Whence Do They Come?

 The USNI newsletter notes:

U.S. fighter aircraft shot down an anti-ship cruise missile the Houthis fired toward USS Laboon (DDG-58), U.S. Central Command announced Sunday night. Central Command’s release did not specify the aircraft that shot down the missile or the military branch. The fighter aircraft shot down the missile off the coast of Al-Hudaydah, according to the release. There were no reports of damage or injury following the strike. The attack on Laboon comes after two days of strikes by the U.S. and the United Kingdom on Houthi targets in Yemen. During the strikes, which involved a number of warships and aircraft, the U.S. and U.K. hit sites that included radar systems, production facilities and munition depots, USNI News previously reported.

Now one may ask; where do these state of the art anti-ship cruise missiles come from. Sanaa in Yemen was a key stop on the trade routes from Aden on to Rome. It also was the source of incense used by Rome when burning bodies. Today Sanaa is a stronghold of the local terrorist clans. 

As far as I know there are no Raytheon or Lockheed factories there, no high tech firms, no universities etc. Thus, from whence do these weapons come? Perhaps addressing the source would be helpful.

BTW, the market for incense has dropped significantly in the last two thousand years.
