What the notice says

ITEM DESCRIPTION - Naval Surface Warfare Center, Crane (NSWC Crane) has a requirement to procure TR-143A Transducers, Part Number: 7146100-302. These transducers are utilized in the SP24 Trident Navigation Subsystem, supporting United States (U.S) Navy and United Kingdom (UK) Ballistic Missile Submarine Nuclear Powered submarines as part of the Navigation Subsystem Sonar. These transducers are used in coordination with TR-333 Hydrophones to receive signals from the ocean floor and to improve submarine launch accuracy. The transducers are manufactured items used as replacement assets during nor… (show all)

mal refit, replenish, and replacement operations for the SP24 Trident Navigation Subsystem and support U.S. Ohio and Columbia class submarines in addition to UK Vanguard and Dreadnought class submarines. The proposed contract action is for a two-year ordering period extension and ceiling increase, on contract N0016426DGP87, a firm-fixed-price, Indefinite Delivery, Indefinite Quantity contract with a five-year ordering period. The contract is for supplies which the Government intends to solicit and negotiate with one source, Massa Products Corporation, Hingham, MA 02043 (CAGE 88958), under the authority of 10 U.S.C. 3204(a)(1) as implemented by FAR 6.103-1 (c) (2), only one responsible source. The requirement is being solicited on a sole source basis, because the supplies have been deemed to be available only from the original source in the case of a follow-on contract for the continued production of highly specialized equipment, including major components thereof, when it is likely that award to any other source would result in (A) Substantial duplication of cost to the Government that is not expected to be recovered through competition or (B) Unacceptable delays in fulfilling the agency�s requirements. Additionally, the Government is pursuing a sole source procurement to mitigate associated certification costs and certification testing that can take up to thirty-six months to complete. Furthermore, if a potential vendor is not capable of meeting the certification requirements, there is high likelihood that ship schedules will be significantly impacted. All responsible sources may submit a capability statement, proposal, or quotation, which shall be considered by the agency. However, a determination by the Government not to compete this proposed contract extension based upon responses to the solicitation is solely within the discretion of the Government. Information received will normally be considered solely for the purpose of re-evaluating the justification for sole source or limitation of sources and making a determination to change the acquisition strategy to a competitive procurement. Contractors must be properly registered in the System for Award Management (SAM). Offerors may obtain information on SAM registration and annual confirmation requirements by calling 1-866-606-8220 or via the internet at https://www.sam.gov.
