Federal Contract Alert: Preserve AFT AEM/S Mast — DEPT OF DEFENSE.DEPT OF THE NAVY.NAVSUP.NAVSUP GLOBAL LOGISTICS SUPPORT.NAVSUP FLC YOKOSUKA.NAVSUP FLT LOG CTR
What Is This Navy Opportunity?
This is a preservation and maintenance contract for the AFT (After) Antenna Equipment Mast (AEM/S) system on Navy vessels operating out of Yokosuka, Japan. NAVSUP FLC (Fleet Logistics Center) Yokosuka is seeking a contractor to perform preventive maintenance, inspections, repairs, and component replacements to keep antenna mast systems operational and mission-ready. This is not new construction—it's sustainment work on existing equipment, which means the Navy has baseline data on failure modes, parts usage, and labor requirements from prior contracts.
Contract Value and Timeline
The solicitation was posted August 7, 2026, with a deadline of September 3, 2026 at 10:00 AM Japan Standard Time. That's a tight 27-day window. Questions submitted after late August will likely not receive timely answers, so if you're serious about bidding, flag this now and pull the full PWS (Performance Work Statement) from SAM immediately.
Who Can Bid? Eligibility and NAICS Code
NAICS 336611 (Ship and Boat Building) is the assigned code, though the actual work is maintenance and repair, not construction. This is unrestricted—no small business set-aside, no 8(a), no HUBZone preference. You're competing against all contractors on the GSA schedule, IDIQ holders, and new bidders. If the incumbent has an existing contract with Navy or is already performing this work elsewhere in the Pacific, expect them to have institutional knowledge and possibly a built-in advantage on labor availability at Yokosuka.
Check your facility clearance status now. Yokosuka is a naval base, so you will need DoD Secret facility clearance or willingness to obtain one. If your company has no cleared facility, this bid is not viable without a significant timeline and cost investment.
How to Respond: Competitive Reality Check
Before drafting a proposal, answer these three questions honestly: (1) Do you have personnel with antenna mast maintenance experience or access to training from the OEM? (2) Can you establish a logistics tail to support operations at a forward naval base in Japan, including parts procurement and technician deployment? (3) Is your labor cost model competitive with regional contractors already embedded in the Western Pacific fleet support ecosystem?
If you answered "no" to any of these, your bid will lose on price or past performance. The Navy does not reward effort here—they measure capability against a threshold and award to the lowest qualified bidder. Look at who bid on the prior contract (check FPDS-NG or ask your contracting officer for competitive history). If three firms with 20+ years of Navy experience are already in the ring, your first bid is a scouting mission, not a win play.
Your proposal must include: a detailed maintenance plan tied to the PWS line items, resumes of key technicians with clearance status, a supply chain plan naming OEM partners or authorized distributors, and a labor rate sheet broken by skill level and geographic location. Travel and shipping costs to/from Yokosuka should be itemized separately—the Navy wants to see that you understand logistics overhead and are not sandbagging price.
CMMC & DFARS Compliance Checklist
This contract involves work on Navy vessels and equipment, which triggers DFARS (Defense Federal Acquisition Regulation Supplement) flow-down requirements. Before you bid, confirm the following in the full solicitation:
CMMC Level Requirement
Antenna mast maintenance is unlikely to require CMMC Level 2 unless you are handling technical data or CUI (Controlled Unclassified Information) related to vessel systems. If the contract does not explicitly require CMMC, assume Level 1 is the floor. However, working at a DoD facility (Yokosuka) means your personnel will be subject to facility access rules and background investigations. Budget for Secret clearance costs if you do not already have a facility clearance.
Key DFARS Clauses to Verify
252.204-7012 (Safeguarding Covered Defense Information): Check whether the PWS requires you to handle technical drawings, maintenance logs, or system specifications that qualify as controlled defense information. If yes, your company must have a compliant information security system before award.
252.204-7019 and 252.204-7020 (CMMC Attestation and Flowdown): These clauses specify whether you must attest to CMMC certification at contract award and whether you must flow CMMC requirements to subcontractors. Review the PWS attachment for the assigned CMMC level. If Level 2 is required and you are not certified, you cannot compete.
SPRS Self-Assessment
If you do not yet have a Secret facility clearance, your SPRS (Security Profile Resource System) self-assessment score must be submitted with your bid or shortly after award. The Navy will not issue a facility clearance to a contractor without a baseline SPRS assessment. This process takes 60-90 days. If you are awarded and your clearance is delayed, Navy may terminate your contract for convenience.
What You Must Have in Place Before Bidding
At minimum: a draft Security Plan outlining how you will control access to any technical data, a list of cleared or clearable personnel, evidence of contractor liability insurance and indemnification coverage, and a point of contact designated as your Facility Security Officer (FSO) or FSO-equivalent. If you do not have these, you are not ready for a DoD contract at a forward base.
Three Actionable Competitive Tips
1. Call the Contracting Officer This Week
Do not wait until August 25 to ask questions. Call now and ask: (a) Is there a facility clearance requirement for technicians on-site at Yokosuka? (b) What is the baseline annual maintenance cost and spare parts budget from the prior contract? (c) Who held the last contract and for how long? The answers will tell you whether this is a competitive open bid or an incumbent-favorable renewal. If the incumbent has been there five years and has zero customer complaints, you are chasing noise.
2. Identify Your OEM Partner Before Proposal Submission
Antenna mast systems are manufactured by a handful of companies (likely Raytheon, General Dynamics, or Ball Aerospace, depending on vessel class). Contact the OEM immediately and ask if they will support your bid with a letter of commitment to supply parts and technical data. Without OEM buy-in, your supply chain section will fail Navy evaluation. The OEM letter is not a proposal requirement, but it is the difference between "technically acceptable" and "best value."
3. Price-to-Win, Not Price-to-Lose
Navy uses competitive range evaluation. If you bid 20% above the incumbent, you will not make competitive range and your proposal will not receive past-performance evaluation. Run your labor, travel, and parts model against the prior contract (filed in FPDS). If you cannot match or beat that number while maintaining margin, do not bid. A lost-cost, low-win-probability bid wastes your proposal development budget. Save the effort for the next Yokosuka IDIQ or a regional supply contract where you have better leverage.
Next Steps
Pull the full solicitation from SAM now, identify the incumbent, and schedule a call with NAVSUP FLC Yokosuka contracting by August 12. If the competitive landscape is unfavorable or your facility clearance is not in place, use this cycle to build relationships and position for the next renewal. Government contracting is a long game—a scouting bid that loses can pay dividends two years later when you have better data and relationships in the channel.
