Just some random info about iraqi weapon industry:
Prior to Gulf War Iraqis had 19 military plants running: the whole range of smallarms and ammo for it. AC, mortar, tank, arty shells. All kinds of MLRS and ballistic rockets. Both west and east variants: like 152 and 155 mm arty shells. Most vehicles were at least partially manufactured in Iraq: brasilian, french, soviet, yugoslavian licenses and so on. Iraqis fielded even own AWACS planes, also used them in last stage of Iran-Iraq War.
How many countries had AWACS back in 1990? Iraq had Baghdad-1 AWACS with radar integrated in tail and improved Adnan-1 conventially looking AWACS with rotodome radar over rump. Both were base on Il-76 cargo plane from USSR. AWACS planes were component of Iraqi IADS (Integrated Air Defence System).
The reason iraqi IADS performed bad against Coalition airforce was that it wasnt designed to work against such overwhelming air power, rather Iran or Israel. 1 plane got destroyed during the Gulf War, 2 planes escaped to Iran.
