Customs and Border Protection (CBP) on Friday awarded initial task orders to four companies under a potential $293.1 million contract to supply the agency with large-scale medium-energy mobile X-Ray systems for border security.

American Science & Engineering [ASEI] received an initial $3.3 million task order, Leidos [LDOS] $3.1 million, OSI Systems’ [OSIS] Rapiscan division $2.9 million, and Britain’s Smiths Group’s Smiths Detection division $3.6 million. The initial task orders satisfy the minimum guaranteed by for each company under the multiple award indefinite-delivery, indefinite-quantity contract, CBP says in a Sept. 11 award notice.

There are no guaranteed task orders beyond the minimum initial awards. All four companies either declined to discuss the award, including the systems they might be supplying, or did not respond for comment. All four companies have supplied container inspection systems to CBP at various times.

CBP originally planned to select up to three vendors for task orders under the original solicitation.

CBP plans to acquire large-scale non-intrusive inspection systems for use at various ports of entry throughout the United States. The systems will be used to inspect trailer trucks, pallets, trailer-mounted cargo containers and other vehicles for contraband such as illicit drugs, terrorist weapons such as weapons of mass destruction, and currency, according to a statement of work CBP issued in May as part of the Request for Proposal.

The mobile systems allow CBP to move the systems to different locations based on intelligence and changing threats.
