Zitat:US Navy states fourth Constellation-class frigate to commission in 2029

The Constellation class will have multi-mission capability to conduct air warfare, anti-submarine warfare, surface warfare, electronic warfare, and information operations. [...] The US Navy has stated that the fourth Constellation-class guided missile frigate will be named USS Lafayette (FFG 65), with the vessel scheduled to commission in 2029. [...]

The difficulties experienced by the LCS also appear in part to have been the motivation behind the US decision to initiate the FFG(X) programme, now known as the Constellation class, which will deliver up to 20 frigates into USN service.

At between $500-600m per ship, the Constellation class is around 50% more expensive per ship than the LCS, although as a much larger warship (7,200t fully loaded) than the LCS Independence variant (3,400t full loaded) and Freedom variant (~3,500t), it necessarily has greater capability, and crucially, survivability.

Meldung zum Baubeginn der ersten FFG(X) von Anfang September 2023:
Zitat:US Navy: Baubeginn der Constellation-Klasse

Die amerikanische Tochter des italienischen Fincantieri-Konzern, Fincantieri Marinette Marine, hat am 31. August mit dem Bau der ersten Fregatte der Constellation-Klasse auf der konzerneigenen Werft in Wisconsin begonnen. Wie aus der Pressemitteilung des für das Projekt zuständigen Programmbüros der US Navy hervorgeht, soll Baunummer 1, die „USS Constellation“ (FFG 62), im Jahr 2026 ausgeliefert werden. Die Klasse wird nach dem Namen des ersten Schiffes sowie als FFG 62 und FFG(X) bezeichnet. [...]

Der Baubeginn der „USS Constellation“ erfolgt fast zweieinhalb Jahre nachdem Fincantieri im April 2020 den Zuschlag erhielt. [...] Gegenüber dem als Grundlage dienenden italienischen Fremm-Design, wird die Constellation-Klasse 7,13 Meter länger (151,20 Meter) und auf Höhe der Wasserlinie 1,10 Meter breiter sein (18,1 Meter), womit sich die Tonnage um rund 520 Tonnen erhöht (7.400 Tonnen). Der Sonardom im Bug entfällt ebenso wie der achtere Mast der Fremm. [...]

Die erste Fregatte der Constellation-Klasse erhält vier diesel-elektrische Antriebe von MTU. Fincantieri Marinette Systems (FMM) hat Rolls-Royce mit der Lieferung der Antriebsaggregate beauftragt (ESuT berichtete). Die Gensets basieren auf Motoren des Typs MTU 20V 4000 M53B, die eine Gesamtleistung von zwölf MW für den Antrieb und die Bordstromversorgung liefern. [...]

In einer Berichterstattung an den US-Kongress werden die Kosten der ersten Einheit mit 1,281 Milliarden USD beziffert.

Wiederbelebung einer alten Debatte...
Zitat:Does The Navy’s New Constellation Class Frigate Have Enough Vertical Launch Cells?

Recent events in the Red Sea again raise questions about whether 32 vertical launch cells is adequate for the Constellation class frigates. [...]

Debates about the Constellation's vertical launch capacity reflects broader concerns, including how these cells might be reloaded at sea in a major conflict, across the Navy as a whole. The underlying issues here have come into sharp relief recently as the service's vessels have been shooting down dozens of Houthi anti-ship ballistic and cruise missiles and drones and launching strikes on the group in Yemen. [...]

Though intended to perform many of the same missions as the Constellation class frigates, both the Freedom and Independence class LCSs have been especially criticized for their very limited armament packages. Their continued lack of air and missile defense capability on the LCSs for anything but close-in defense has been particularly glaring. Freedom and Independence class ships have been prominently absent from the current crisis in and around the Red Sea, which is by definition a littoral combat environment, underlying the ambiguous use case and poor return on investment of these ships many years after they entered into Navy service. [...]

When it comes to vertical launch system (VLS) capacity, there had been questions about the configuration of the Mk 41 array for Navy's new frigates even before the FREMM-based design was selected. The original threshold requirements for FFG(X), a program that was first announced publicly in 2017, called for just 16 VLS cells. By the time competition was over, this had increased to 32.

For comparison, each of the Navy's Flight I and II Arleigh Burke class destroyers have 90 Mk 41 VLS cells. Flight IIA and other subsequent subvariants of the Arleigh Burke have 96 cells. The service's trio of Zumwalt class destroyers feature Mk 57 VLS arrays, derived from the Mk 41, with 80 cells in total (these ships are also getting all new large vertical launch tubes primarily for firing hypersonic missiles). The Navy's Ticonderoga class cruisers, the last of which are slated to be decommissioned before the end of the decade, have 122 Mk 41 VLS cells apiece. All of these ships are, of course, notably larger than Constellation.

Die Diskussion läuft in amerikanischen Foren seit es Pläne dafür gab.

Man hat ja gegenüber dem ersten Entwurf die Zahl der VLS-Zellen auf 32 verdoppelt.

32 VLS Zellen für eine Fregatte reichen in einer Marine mit perspektivisch 100 Zerstörern und 10.000 VLS Zellen allemal. Erst recht wenn die Munitionsbestände schon die vorhandenen VLS kaum füllen können.

Notfalls könnte man anstatt der 16 (!) NSM auch zusätzlich SeaRAM oder ESSM Starter mitführen.

Zitat:Greece announces plans for joint production of Constellation-class frigates

Greek Minister of National Defence Nikos Dendias has announced that the country is interested in the joint production of a modified version of the Constellation-class frigates being built for the US Navy (USN). Dendias' comments were made following a meeting with the defence minister of the Republic of Cyprus on 29 January.

“On 16 January we received a letter from the US Navy accepting in principle our interest in the co-design and co-production of up to seven new Constellation-class frigates in Greek shipyards,” Dendias said. If an agreement could be reached, Dendias added, Greece would be able to participate in the programme from the beginning and could accordingly contribute to designing and customising the ships according to the needs of the Hellenic Navy.

The Constellation-class frigate design is derived from the Italian Navy's Bergamini-class FREMM (Frégate Européenne Multi-Mission) frigates. Four ships are being built for the USN at Fincantieri Marinette Marine, with total procurement of up to 16 further units planned.
