The Navy intends to award a cost-plus-fixed-fee and cost-reimbursement task order to L3 Technologies under an exception to fair opportunity, as only this contractor can provide the required services. The effort covers sustainment, technical, engineering, and administrative services for the proprietary L3 Control Element Software supporting the Orca Extra Large Unmanned Undersea Vehicle program. A redacted justification for the exception to fair opportunity is attached to the notice.
