What the notice says
N0016425RGP87 � SOLE SOURCE � TR-143A TRANSDUCERS � PSC 6605 � NAICS 334511 Anticipated Issue Date: 10 JUNE 2025 � Anticipated Closing Date: 14 JULY 2025 � Time Eastern 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 H… (show all)
ydrophones to receive signals from the ocean floor and to improve submarine launch accuracy. The transducers are manufactured items used as replacement assets during normal 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, a firm-fixed-price, Indefinite Delivery, Indefinite Quantity contract with a five-year ordering period, is for the supplies for 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 6.302-1(a)(2)(ii), 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 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. Questions or inquiries should be directed to Kori Johnston, Code 0221, e-mail kori.a.johnston.civ@us.navy.mil. Please reference the above solicitation number when responding to this notice.

Value counts new single-winner awards. "Shared" awards are multiple-award contracts that list every winner with the same total ceiling (same contract, or the same office, day and amount); that ceiling is not one company's win, so it is not added in. Contract modifications are not new awards and are not added in either. Notices whose amount is a placeholder such as $999,999,999 are not added in. Revenue next to a ticker is the company's revenue over the latest 12 months in its SEC filings.

- $RTX reported $93.5B revenue (12 months to Jun 30, 2026). The median single-winner award in these 29 past awards, $19.8M, is under 0.1% of that. SEC filing
