Modernisation vs Modification - Marcin Ryngwelski on Polish Navy Upgrades

In the world of naval shipbuilding, not all upgrades are created equal. While the terms modernisation and modification may sound interchangeable, in practice they involve different objectives, scopes of work, and—critically—different contracting authorities within the Polish Ministry of National Defence (MON).

- Modernisation projects are commissioned by the Armament Agency in Warsaw, via the Naval Technology Directorate. Modifications, on the other hand, are handled by the Support Inspectorate in Bydgoszcz, explains Marcin Ryngwelski, President of PGZ Naval Shipyard (PGZ Stocznia Wojenna).

While both types of work may target the same class of naval vessels, the overseeing entities, funding lines, and technical deliverables are distinct.

- For example, modification of the ORKAN-class fast attack craft is under the Support Inspectorate. Potential modernisation of ORP Ślązak falls under the Armament Agency, adds Ryngwelski.

ORKAN vs Ślązak – Two Ships, Two Strategies

A current example of modification is underway on ORKAN-class vessels, where PGZ Naval Shipyard is executing a scope contracted via the Naval Port Command. The effort has been integrated with scheduled dry-dock and major overhauls. Key deliverables include:

• Reconfiguring the propulsion system from three to two engines
• Replacing obsolete Soviet-era diesel engines with new-generation units
• Overhauling electrical infrastructure and IT networks

Interestingly, the ships were originally intended to undergo full-scale modernisation—including a replacement of the integrated combat management system.

- Due to budgetary constraints, the task was reassigned from the former Armament Inspectorate to the Support Inspectorate, Ryngwelski notes. The change in mandate significantly narrowed the scope and funding available for the shipyard.

Meanwhile, ORP Ślązak is expected to undergo a true modernisation—pending final approval and launch by the Armament Agency. Planned upgrades include:

• Acquisition and installation of surface-to-air missile launchers
• Integration of next-generation electronic warfare systems
• Installation of anti-surface and land-attack weapons

Lifecycle Support – An International Standard

- It’s standard practice worldwide that the shipyard responsible for building a naval vessel continues to service, modify, and modernise it throughout its lifecycle—until decommissioning, says Ryngwelski.

This approach ensures technical continuity, reduces integration risks, and leverages the shipbuilder’s familiarity with the platform—especially in complex naval environments where interoperability and system-level reliability are non-negotiable.
