About this file

This is a Standard Form 30 (Amendment of Solicitation/Modification of Contract) issued by the Naval Supply Fleet Logistics Center Yokosuka for solicitation N6264926RA065.

Amendment Details and Vessel Specifications

Amendment 0001 was issued on July 31, 2026, with an effective date of July 31, 2026, in response to a contractor question regarding propeller specifications for the Work Boat Medium (WBM-1) vessel. The amendment addresses a discrepancy in paragraph 4.2.1 concerning Rice Kaplan Style Propeller specifications. The original specification called for a propeller with a diameter of 38" x 38" pitch, 0.80 DAR (diameter area ratio), 4 blades, and 3" Standard dimensions. However, the Stamping Record of the existing propeller indicated the pitch had been changed to 38" x 36.8". The government response, provided by contracting officer Neil S. Flint, recommends procuring 38" x 36.8" propellers to match the existing size, ensuring engine performance and vessel characteristics remain unchanged. Offers must acknowledge receipt of this amendment prior to the hour and date specified in the solicitation, either by completing items 8 and 15 and returning copies of the amendment, by acknowledging receipt on each copy of the offer submitted, or by separate letter or electronic communication referencing the solicitation and amendment numbers.

CONTRACTOR QUESTION:

1. We have one question on para 4.2.1 "Rice Kaplan Style Propeller with a diameter of 38" x 38" pitch, 0.80 DAR, 4 blades, 3" Standard". From Stamping Record of Existing Propeller, it seems to be pitch was changed to 38" x 36.8", but should we procure 38" x 38" pitch?
