Five actions, five different results
The Maritime storefront on drones.mil sits inside a Department-wide marketplace that runs under an Army Commercial Solutions Opening. The Navy decides what appears there by issuing calls, and the one open in October 2026 covers Phase II medium unmanned surface vessels. Every other move a maritime firm can make, from the PAE RAS Front Door to a solution brief to consortium membership, produces something else, and none of them places a product on the storefront.
The open call has its own traps. Its call number duplicates the number on an Army Group 3 aircraft call, it refers to a placemat template that was not among the posted attachments, and it contradicts itself on how the first step is rated. The offeror pays for the sea demonstration, and a listed vessel carries no minimum order.
What the paper answers
- Who runs the Maritime storefront, and under which authorities does it operate?
- Does your vessel meet the seven requirements in the Navy's MUSV call?
- How far may a production vessel differ from the one demonstrated at sea?
- What must the demonstration show to earn a pass?
- What can a firm do when no call covers its product?
- How do end users choose among listed vessels once the agreement is in place?
A look inside
One of three tables in the paper. A production vessel that exceeds any of these limits will not be considered.
| Characteristic | Maximum allowed change from the demonstrated vessel to the production unit |
|---|---|
| Hullform | Same hull type required. |
| Material | Same hull and deckhouse material required. |
| Length overall | 15 percent. |
| Beam | 15 percent. |
| Full-load displacement | 10 percent. |
| Sustained speed | 2 knots faster. Any amount slower is acceptable. |
| Repowering, propulsion | Any change within an engine model rating, or a 30 percent increase in brake horsepower. Any decrease is acceptable. |
| Repowering, electrical | 100 percent increase in electrical kilowatts. Any decrease is acceptable. |
| Propulsor type | No deviation from type permitted. |
| Autonomy | Same autonomy provider and autonomy baseline. Other deviations are subject to Government approval. |
| Perception | Subject to Government approval. |

What's inside
- A comparison of five actions open to a maritime firm: who each is open to, its status, what it takes and what it can lead to.
- The three qualification steps in the Navy call, with format rules, grading and results.
- Eligibility and registration requirements, including the conflict-of-interest analysis submitted with the initial package.
- The call's internal inconsistencies and the questions to put to the Agreements Officer before relying on a reading.
- Seven recommendations and 12 references to the calls, notices and official pages.
Every required demonstration event
The paper sets out each event the sea demonstration must cover, including:
- Sustained speed, maneuverability and fuel burn at the advertised range speeds
- An unmanned mission of at least 24 continuous hours, 24 waypoints and 300 nautical miles
- Keep-in and keep-out zones, and navigation from chart data around charted objects, shallow water and land
- At least 20 contact interactions under the collision regulations, including overtaking under Rule 13(d)
Who it's for
- Builders of medium unmanned surface vessels weighing the Navy's open call.
- Makers of maritime payloads, autonomy software and subsystems with no category call of their own.
- Unmanned undersea vehicle firms looking for a way into the Navy's robotic and autonomous systems portfolio.
- Capture leads choosing between the Front Door, a solution brief and consortium membership.

Questions
- Does a listing mean the Navy will buy my vessel?
- No. The agreement that follows qualification sets no minimum order. End users choose among listed vessels on capability, total price and lead time.
- Does the Navy pay for the sea demonstration?
- No. Under the Navy call the Government does not fund or reimburse any of the three qualification steps.
- Is this legal advice?
- No. It is a practitioner's guide. The call, its parent opening and any amendments control, so confirm the current text on SAM.gov and PIEE before submitting.
- I already subscribe to Closing Rate. Do I need to buy it?
