Key dates and what happens at the deadline

Who this opportunity suits

This opportunity is suitable for businesses that can supply diesel engines with containers, specifically those matching part number 57K6791 and NSN 2815-01-562-6787. The technical data is available, but the top drawing is controlled by Oshkosh Defense (CAGE 75Q65). Vendors should have experience with military packaging requirements (PKG: Military A) and understand that inspection and acceptance will occur at the origin (INSP/ACCP: Origin/Origin) and the Free On Board (FOB) point is origin.

Tips for preparing a competitive response

Carefully review all solicitation documents to ensure full compliance with every requirement. Pay close attention to the specific part number, NSN, and packaging instructions. Since a reverse auction may be used, be prepared to potentially adjust your pricing during that phase if it occurs. Ensure your company is registered in the reverse auction system and that your representative completes the necessary online training if you intend to participate.

Given that the top drawing is source-controlled by Oshkosh Defense, understand any implications this may have for your ability to meet the specifications. Clearly articulate your capacity to meet the minimum and estimated maximum quantities over the 3-year contract period.
