German Frigate Programmes: F123 Modernisation, F126 to MEKO A-200, F127
A dated ledger tracking Germany's F126-to-MEKO-A-200 pivot, the F127 Aegis frigate and F123 modernisation, contract by contract.
This page is a maintained ledger of Germany's surface-combatant programmes — F123, F126/F128 and F127 — updated as each contract, budget vote or export clearance lands.
Why this page exists
Germany is rebuilding its surface fleet across three programmes at once, and the middle one collapsed and was rebuilt inside a single summer: the F126 anti-submarine frigate was cancelled on 24 June 2026 after its cost-to-complete estimate reached roughly €18bn, and a replacement — up to eight TKMS MEKO A-200 DEU frigates designated F128 — was submitted, priced, approved with conditions and given its first supplier contract within seven weeks. Tracking that sequence, alongside the F127 air-defence frigate's separate Aegis/SPY-6 export clearance and the F123's ongoing life-extension work, means following BMVg statements, Bundestag budget-committee sessions, and company releases from Rheinmetall, TKMS and Saab that each cover one piece of a fast-moving, three-programme file.
This hub holds the dated sequence in one place so a reader does not have to reconstruct it from separate dispatches: what was approved, what was only proposed, what is still pending a Bundestag vote, and where Großwald's own reporting has fallen behind the record it was tracking.
State of play
F123 Brandenburg-class: extending four hulls to 2035
Germany's four Brandenburg-class F123 frigates, in service since 1996, are absorbing the near-term sustainment budget while the newer classes work through procurement. On 11 June 2026 the Bundestag's budget committee cleared a Saab-integrated anti-submarine-warfare and torpedo-detection change order touching the ships' sensors and combat-management system — a change order, not a stand-alone sonar buy. Separately, at the end of the second quarter, Rheinmetall's Neue Jadewerft yard in Wilhelmshaven took a mid-three-hundred-million-euro contract to modernise the lead ship BAYERN: replacing the combat-management system outright, refreshing the radar suite, upgrading anti-submarine capability and overhauling propulsion, running to 2029 and intended to hold the class in service to at least 2035. BAYERN is already alongside at Wilhelmshaven with major components removed. The class's three sister ships have no modernisation order announced, so whether the BAYERN contract scales to the full class is still open — F123 is the sustainment floor under two new-build programmes still working through contracts of their own.
The F126 collapse and the F128 rebuild
On 24 June 2026 the defence ministry cancelled the six-ship F126 anti-submarine frigate programme — the largest surface-combatant project in postwar German naval history — after Damen Schelde Naval Shipbuilding notified Berlin it could not deliver on schedule or budget, and after the ministry judged a Rheinmetall-led rescue would still cost roughly €18bn against an original €10bn estimate, with the first ship slipping to 2032. Roughly €2–3.5bn was already sunk. In its place the Navy chose up to eight TKMS MEKO A-200 DEU frigates, an existing design about a third the F126's size: four firm at roughly €6.3bn, four optioned by end-2026 at roughly €5.3bn, first delivery targeted for 2029.
The replacement, designated F128, moved fast and then stalled. BMVg's 2 July submission priced four ships at €6.63bn — about 70 per cent above earlier estimates, mostly the cost of halving the batch and adding strike-length launch cells — with the entire F126 contractor team replaced: TKMS as prime, Saab on the combat system, Atlas Elektronik on sonar, Kongsberg on the Naval Strike Missile. The Bundestag budget committee approved the buy on 8 July, attaching conditions — quarterly reporting, cost control, a look at bringing former F126 subcontractors back in, and no slip past the December 2029 delivery date. Saab's roughly €790m combat-system order followed on 16 July; on 12 August TKMS signalled it would open the second four-ship batch to those returning suppliers.
Rheinmetall's naval bet and its unwind
Rheinmetall's move into warship-building ran through the March 2026 close of its Naval Vessels Lürssen acquisition — four yards (Peene-Werft, Blohm+Voss, Norderwerft, Neue Jadewerft) and about 2,100 staff — meant to convert a components supplier into a prime capable of delivering complete armed ships. F126 was the anchor: a non-binding roughly €12bn takeover bid tabled on 6 May 2026 was overtaken by the June cancellation, and the loss cost the company about €300m of 2026 revenue guidance, cut to €13.7–14.2bn at the August half-year results against a backlog that had still reached €80.5bn. Rheinmetall kept the F123 BAYERN sustainment contract and a non-binding bid for German Naval Yards Kiel — the yard tied to F127 construction — placed on 8 May and still unresolved after TKMS withdrew its own rival GNYK bid on 21 July. On 3 August the company unveiled the GMF 140, a 6,000-tonne Aegis-armed frigate design pitched first at a North American competition, with no customer, yard or schedule named.
F127: the Aegis air-defence frigate without a budget vote
The F127, replacing the F124 Sachsen class, is the programme with the largest number and the thinnest parliamentary paper trail. On 17 April 2026 the US State Department cleared a Foreign Military Sale worth up to $11.9bn for eight shipsets of Aegis Combat System MK 6 MOD X and AN/SPY-6(V)1 radar, making Germany the first customer for that radar variant outside the US Navy; the Mk 41 vertical-launch system grew from 64 to 96 cells per hull under Baseline VIII, and $3.5bn of the package covers 173 SM-6 Block I and 577 SM-2 Block IIIC missiles. Entry into service is scheduled from the mid-2030s. What has not followed is a Bundestag budget-committee vote: Rheinmetall chief executive Armin Papperger said in May that the ministry's capacity meant no F127 procurement decision was likely in 2026, and the yard question — German Naval Yards Kiel, contested between Rheinmetall and TKMS — remains open.
Adjacent threads: ammunition, combat systems and the Dutch Aegis question
Two smaller moves round out the picture. Diehl Defence and BAE Systems signed a memorandum on 3 August to pair Diehl's 127mm Vulcano-family guided round with BAE's Mk 45 Mod 4 naval gun — fielded across a far larger allied fleet than any German hull — and to examine fitting IRIS-T into BAE's maritime launchers; no contract, schedule or qualification programme yet exists. Separately, the Netherlands sent Washington a Letter of Request in January 2026 for an Aegis variant to equip its own F126 follow-on tranche, with a US response received in April; Germany's cancellation of the F126 programme itself has left the design's export future — and therefore the Dutch decision — unresolved and unaddressed in any later reporting Großwald has traced. The K130 corvette fleet, unrelated to frigates but sharing the same yards, reached ten hulls with the 29 April christening of Lübeck, the final Batch-2 ship.

The contrarian read
The standing narrative reads the F126 collapse as an industrial failure that TKMS's readiness fixed and Rheinmetall's overreach exposed. A colder reading is that Berlin's own decisions did as much to drive cost as any contractor's: the ministry chose to buy only half the eight-ship batch it could have ordered outright, and that single choice generates most of the 70 per cent per-hull cost increase on the F128 — the state paying a price for its own caution, not for someone else's failure. The replacement package was assembled and pushed through the budget committee within seven weeks of cancellation, with conditions — quarterly reporting, cost control, no schedule slip — that read less like routine oversight than an admission that oversight, not shipbuilding capacity, was what went missing on F126. And the ministry has applied none of that urgency to F127: an Aegis programme worth more than the F126 ever was has sat without a budget-committee submission for over a year, while the yard meant to build it changes hands in an unresolved contest between the same two primes.
What to watch
F128 second batch
Berlin's option for four more MEKO A-200 DEU frigates (~€5.3bn) is exercisable through end-2026; watch whether it is taken up, and whether the returning ex-F126 subcontractors named in the 8 July conditions actually appear on the contract.
GNYK ownership
TKMS withdrew its bid for German Naval Yards Kiel on 21 July 2026; Rheinmetall's rival non-binding offer from 8 May is still open. Since GNYK builds F127 hulls, whoever wins shapes who delivers Germany's air-defence frigate.
F127 budget vote
The $11.9bn Aegis/SPY-6 export clearance dates to April 2026; no Bundestag budget-committee submission has followed, and Rheinmetall's chief executive said in May a 2026 decision was unlikely. A submission — or its continued absence — is the next dated gate.
F128 delivery date
The Bundestag's 8 July conditions require the December 2029 first-delivery date to hold; the F126 it replaces slipped from 2028 to a projected 2032 before cancellation, so 2029 is the new programme's first credibility test.
GMF 140 customer
Rheinmetall's GMF 140 design carries no named competition, yard or customer as of its 3 August unveiling; a named North American procurement process would be the first sign the design is more than a rendering.
