Germany Advances F123 Frigate Modernization, Aligning Future F128 Fleet
6/11/2026, 9:17:43 PM
Background & Context
The Brandenburg-class (F123) frigates, commissioned in the 1990s, are the German Navy’s primary anti-submarine warfare (ASW) platform. Aging sonar and weapons have prompted a mid-life update (MLU) to keep them relevant against modern undersea threats.
Modernization Initiative and ASW Restoration
A €25 million amendment to the F123 MLU contract is slated for discussion by the Bundestag’s Defense Committee. The amendment authorises commissioning services to restore the frigates’ ASW capability, ensuring the four F123 ships remain effective in submarine-hunting roles after the upgrade.
Technical Upgrades and System Integration
The upgrade adds GeoSpectrum’s TRAPS towed sonar, chosen for its compact size after Atlas Elektronik’s system was ruled out. Saab will provide the 9LV command system, Sea Giraffe 4A/1X radars, Ceros 200 fire-control and IFF. Further electronic-warfare modules from Elbit are expected.
Timeline and Delivery Schedule
The MLU design freeze was completed at the end of 2023, allowing work to start in 2024. Delivery of the modernized frigates is set for 2029, aligning with the first F128 entry.
Data & Statistics
The amendment earmarks €25 million for ASW restoration. Four F123 frigates will be upgraded and four F128 frigates are planned, creating eight ships with a common sensor suite. The navy also operates six F126 and eight F127 frigates, with reports of up to €6 billion per F127.
Commonality with Future F128 Frigates
The 9LV command system, radars and fire-control suite chosen for the F123 upgrade will also equip the upcoming MEKO A-200-based F128 class. While the navy intends to adopt the CMS 330 from Lockheed Martin Canada as a future standard, it retained the 9LV to avoid risking an untested system before the 2029 delivery. Observers say a later swap to CMS 330 is possible.
Operational and Logistical Impact
Standardising eight frigates on an identical suite simplifies spare-parts supply, maintenance training and crew qualification, strengthening the navy’s ASW posture. The larger fleet will raise recruitment needs and could strain the defence budget, especially alongside six F126 and eight F127 vessels.
Official Statements & Responses
The Bundestag Defense Committee’s upcoming debate reflects parliamentary oversight of the €25 million amendment. The Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw) confirmed Saab’s role in delivering the 9LV system, radars and fire-control components, and affirmed integration of GeoSpectrum’s TRAPS sonar for ASW restoration.
Criticism, Financial Concerns, and Opposition
Analysts warn that estimates of up to €6 billion per F127 frigate would be politically hard to justify. Retaining the 9LV instead of the newer CMS 330 has been criticised as short-term risk mitigation that could delay broader modernisation. Funding eight identically equipped frigates alongside existing programmes poses a budgetary challenge.
Conflicting Reports & Information Gaps
Precise cost figures for the F127 class remain unconfirmed, and no official decision has been announced on replacing the 9LV with the CMS 330 on the F128. The scope of additional electronic-warfare equipment from Elbit beyond the TRAPS sonar has not been disclosed.
