Spanish shipyards with public aid granted under the Royal Decree 874/2017 or the Royal Decree 1071/2021 gain room for maneuver as of September 4, 2026. Royal Decree 709/2026 corrects an omission in the transitional regime of RD 485/2025 that left those who already had approval resolution at a disadvantage compared to those who had not yet obtained it.
The correction is surgical: a new letter c) is added to the transitional regime to equalize the treatment of all beneficiaries in an equivalent situation, regardless of when their resolution was issued.
What does this regulation establish?
RD 485/2025 already allowed modification of aid approval resolutions for naval construction when substantial changes occurred in the contract or ship financing. However, this possibility was limited to files that did not have prior approval resolution. Files that had already received approval were excluded, without objective justification.
RD 709/2026 corrects this omission by adding a new letter c) to the transitional regime, with the following scope:
| Situation | Before RD 709/2026 | After RD 709/2026 |
|---|---|---|
| Files without prior approval resolution | Could request modification for substantial changes | No changes — they continue to be able to request it |
| Files with prior approval resolution (ship not delivered) | Could not request modification | Now can request modification for substantial changes |
| Files with prior approval resolution (ship already delivered) | Could not request modification | Continue unable to request it — delivered ship closes the file |
The determining condition is clear: the ship must not have been delivered to the shipowner. Once delivery occurs, the file is considered closed and modification is not possible.
The regulation does not create new administrative burdens or require additional documentation compared to the procedure already existing for files without prior resolution.
Economic and operational impact
For affected shipyards, the impact is fundamentally one of reduction of financial and contractual risk. In naval construction, contracts are signed years before ship delivery. During that period, substantial changes can occur in:
- The conditions of the ship construction contract (technical specifications, deadlines, price)
- The financing structure of the project (changes in official credit, refinancing)
Without the possibility of modifying the approval resolution, a shipyard with aid already granted that faces a substantial change in the contract could be forced to choose between renouncing the aid or breaching the conditions of the grant. Both options have direct economic cost.
With RD 709/2026, that risk disappears for files with prior resolution, as long as the ship has not been delivered. The shipyard can request adaptation of the resolution to the new contractual or financial reality, maintaining access to the interest rate subsidy or naval R&D+i aid.
Who does it affect?
- Spanish shipyards with approval resolution for aid at the interest rate of credits for ship construction (RD 874/2017), as long as the ship has not been delivered to the shipowner.
- Naval construction companies beneficiaries of aid in research, development and innovation (RD 1071/2021), in the same situation.
- Financial directors and project managers in shipyards managing aid files with prior resolution and ongoing contracts subject to possible changes.
- Advisors and consultants specialized in naval financing and public subsidies to the maritime sector.
It does not affect shipyards whose ships have already been delivered to the shipowner, nor files that have not received approval resolution (these were already covered by RD 485/2025).
Practical example
A shipyard obtained in 2024 an approval resolution for interest rate aid for the construction of a cargo ship. In 2026, the shipowner requests relevant technical modifications to the ship's specifications that alter the cost and delivery schedule, forcing renegotiation of the official credit conditions linked to the aid.
Before RD 709/2026, that shipyard could not request modification of its approval resolution because it already had prior resolution. It had to choose between assuming the contractual change without adapting the aid (with risk of breach of conditions) or renouncing the subsidy.
As of September 4, 2026, that same shipyard can formally request modification of its approval resolution to adapt it to the new contract and financing, as long as the ship has not been delivered to the shipowner. The procedure is the same as already existed for files without prior resolution, without additional documentation.
What should companies do now?
- Identify files with prior approval resolution that have the ship not yet delivered to the shipowner. These are the ones that can now take advantage of the new possibility.
- Review whether there are substantial changes in the ship construction contract or in its financing that justify requesting a modification of the approval resolution.
- Consult with the granting authority the specific procedure for requesting the modification, since RD 709/2026 does not introduce additional documentation compared to the procedure already in force.
- Act before ship delivery: once the ship is delivered to the shipowner, the possibility of modifying the resolution is permanently closed.
- Document the substantial changes in the contract or financing that motivate the modification request, to prove compliance with the requirements of the transitional regime.
Frequently asked questions
What shipyards can request modification of their approval resolution after RD 709/2026?
Shipyards that have an already approved aid approval resolution (under RD 874/2017 or RD 1071/2021) and whose ship has not been delivered to the shipowner. If the ship has already been delivered, it is not possible to request modification.
What types of changes justify requesting modification of the approval resolution?
Substantial changes in the ship construction contract or in its financing structure. RD 709/2026 does not exhaustively define what is considered a "substantial change", so it is advisable to consult with the granting authority for any relevant modification in price, deadlines, technical specifications or official credit conditions.
When does RD 709/2026 enter into force and from when can modification be requested?
Royal Decree 709/2026 enters into force on September 4, 2026, one day after its publication in the BOE (September 3, 2026). From that date, files with prior resolution can request modification.
Are there new administrative burdens or additional documentation to request modification?
No. RD 709/2026 expressly establishes that the measure does not create new administrative burdens or require additional documentation compared to the procedure already existing for files without prior resolution.
What happens if the shipyard does not request modification and the contract changes substantially?
Without requesting modification of the approval resolution, the shipyard could breach the conditions under which the aid was granted, which could result in total or partial loss of the subsidy. It is essential to act before the ship is delivered to the shipowner.
