Blackwater Worldwide was employed to assist the Hurricane Katrina relief efforts on the Gulf Coast. According to a company press release, it provided airlift, security, logistics, and transportation services, as well as humanitarian support. It was reported that the company also acted as law enforcement in the disaster-stricken areas, for example securing neighborhoods and confronting criminals. Blackwater moved about 200 personnel into the area hit by Hurricane Katrina, most of whom (164 employees) were working under a contract with the Department of Homeland Security to protect government facilities, but the company held contracts with private clients as well. Overall, Blackwater had a "visible, and financially lucrative, presence in the immediate aftermath of Hurricane Katrina as the use of the company contractors cost U.S. taxpayers $240,000 a day. There has been much dispute surrounding governmental contracts in post-Katrina New Orleans, especially no-bid contracts such as the one Xe was awarded. Xe's heavily-armed presence in the city was also the subject of much confusion and criticism.
Xe is one of five companies picked by the Department of Defence Counter-Narcotics Technology Program Office in a five-year contract for equipment, material and services in support of counter-narcotics activities. The contract is worth up to $15 billion. The other companies picked are Raytheon, Lockheed Martin, Northrop Gurmman and Arinc Inc. Blackwater USA has also been contracted by various foreign governments. The DEA and DoD counternarcotics program is supported by Blackwater Worldwide in Afghanistan as well.“Blackwater is involved on DoD side” of the counter-narcotics program in Afghanistan says Jeff Gibson, vice president for international training at Blackwater. “We interdict. The NIU surgically goes after shipments going to Iran or Pakistan. We provide training to set up roadblocks, identify where drug lords are, and act so as not to impact the community. About 16 Blackwater personnel are in Afghanistan at any given time to support DoD and DEA efforts at training facilities around the country. Blackwater is also involved in mentoring Afghan officials in drug interdiction and counter narcotics. As Richard Douglas, a deputy assistant secretary of defense, explained, "The fact is, we use Blackwater to do a lot of our training of counternarcotics police in Afghanistan. I have to say that Blackwater has done a very good job.
In 2005, it worked to train the Naval Sea Commando regiment of Azerbaijan, enhancing their interdiction capabilities on the Caspian Sea. In Asia, Blackwater has contracts in Japan guarding AN/TP-2 radar systems.
