The government does not own the technical data needed to manufacture this item, so interested firms should contact the original equipment manufacturer (Mission Systems Davenport Inc). This acquisition is not set aside for small business and involves export-controlled technology, with foreign participation subject to restrictions. The government intends to solicit from a limited number of sources, but all responsible parties may submit a proposal for consideration.
