The Department of Homeland Security, specifically the U.S. Customs and Border Protection, is planning to issue a Sole Source Contract Modification to General Atomics Aeronautical Systems, Inc. for the procurement of up to eleven MQ-9 Unmanned Aircraft Systems. This contract modification aims to increase the contract ceiling and extend the performance period by an additional 12 months, from October 1, 2026, to September 30, 2027, to support anticipated aircraft deliveries and ongoing operational and maintenance services for the existing UAS fleet. The MQ-9 systems are critical for enhancing the DHS's mission capabilities in border security and surveillance operations. Interested parties are encouraged to express their interest and capabilities in writing to Brenda Mealer at brenda.mealer@cbp.dhs.gov prior to the closing date of this notice, as this is not a request for proposals or bids.
