The Naval Air Warfare Center Aircraft Division in Lakehurst, NJ intends to negotiate on a non-competitive, sole-source basis with Jeppesen ForeFlight to add up to ten commercial-off-the-shelf annual navigation database software subscriptions to an existing indefinite delivery, indefinite quantity contract. This action is justified under FAR 6.302-1, citing that only one responsible source can satisfy the requirement and that competition would likely cause substantial duplication of costs. This notice is not a request for proposal, but all responsible sources may submit a capability statement, proposal, or quotation for consideration by the agency. No contract will be awarded based on responses to this notice, and the government retains discretion on whether to compete the requirement. Performance is located at Lakehurst, New Jersey.
