U.S. forces in the Persian Gulf. In the 2002 NIE, the IC assessed that Iraq was developing a UAV, "probably intended to deliver biological warfare agents," which could threaten the US. homeland if brought close to or into the U.S. The statement that the UAV was probably intended to deliver biological agents was made in the key judgments, and not in the main body of the delivery section of the NIE. The USAF disagreed with this assessment and added a footnote to the NIE which noted that it "does not agree that Iraq is developing UAVs primarily intended to be delivery platforms for chemical and biological warfare (CBW) agents. The small size of Iraq's new UAV strongly suggests a primary role of reconnaissance, although CBW delivery is an inherent capability." Of note, the text of the biological warfare section of the NIE was similar to the USAF footnote in stating that "although we have no information linking the current UAV development with BW delivery, this new airframe may represent another future method of BW delivery." The NIE assessment that Iraq was developing UAVs probably intended for BW delivery was based in part on information from UN inspections and Iraqi declarations. showed that in 1995 Iraq declared that it had a pre-Gulf War project to convert MIG-21 aircraft to pilotless aircraft with a drop tank that would deliver biological agent. Iraq conducted one experiment with this aircraft in 1991, but Iraq said it dropped the project because of the war. prior to the Gulf War, Iraq had been working on a program to modify drop tanks for use on an F-1 Mirage fighter for chemical and biological weapons (CBW) dispersal, and had tested the aircraft using an anthrax simulant. Although this was a manned aircraft, IC analysts assessed that the drop tank work could have had applications for use with UAVs. It was also noted that Iraq had modified commercial crop sprayers for BW delivery at the Salman Pak facility that were assessed to be suitable for the dissemination of BW agents from helicopters or slow-moving fixed-wing aircraft. IC analysts told Committee staff that when Iraq began to convert 1960s Czech-built L-29 jet trainers into UAVs in 1995, they assessed that Iraq may have intended to use the L-29s for CBW delivery instead of the MIG-21s they had worked on prior to the Gulf War. The IC provided the Committee with
