This is a sole source requirement for the repair of one specific flight display unit, as the government lacks the data to contract with any source other than the current one. The work is intended to be awarded under an already established Basic Ordering Agreement (BOA) with NAVSUP WSS Philadelphia. The induction period for the initial unit is 365 calendar days from award, with a government option to extend that period by an additional 365 days. The contractor must propose option pricing for up to 10 total units over the potential two-year contract period. Offers from non-approved sources must include a complete source approval submission with their proposal to be considered.
