• The acquisition is listed as UNRESTRICTED.

• Vendors must provide their CAGE Code, DUNS number, SAM registration status, and Tax ID Number.

• Paperless distribution of purchase orders, contracts, and modifications is required.

• Delivery is to Pearl Harbor, HI, with an estimated delivery date of March 17, 2026.

Amendment / Modification

• The solicitation closing date has been extended.

• Section A - Solicitation/Contract Form: The Response Due Date has been changed.

• The proposal submission deadline has been extended from February 23, 2026, to February 27, 2026. This extension is noted as being due to a lack of received quotes.

Amendment / Modification

This document modifies the "MODIFIED ULTRASONIC TEST REQUIREMENTS FOR LAMINAR DISCONTINUITIES" by making the following changes to MIL-T-16420K:

• Paragraph 3.4.3.4: The original paragraph is deleted and replaced with new text specifying that tubes with laminar discontinuities showing indications exceeding exploration threshold levels (20% for contact method at +6dB; 30% for immersion method at calibration) shall be rejected.
• Paragraph 4.4.7 (Second Sentence): The term "18-INCH" is deleted and replaced with "1-INCH."
• Paragraph 4.4.7 (Last Sentence): The phrase "3.4.3.4. AND" is inserted before "3.8.2. SHALL BE REJECTED."

• Paragraph 3.4.3.4 of MIL-T-16420K
• Paragraph 4.4.7 of MIL-T-16420K

These changes modify specific technical requirements related to ultrasonic testing for laminar discontinuities. Bidders should ensure their proposals and understanding of the requirements align with these updated specifications.
