StingrayThe F-105 design was updated for the US frigate bids. They being Navantia and G&C completely reworked the ship in a number of areas, and it would be essentially a flight II of the design if built. The US paid for this work, it was extensive, Warren was talking about it before stepping down. The F-105 proposal went quite far, but eventually lost out to the FREMM proposal that is now the constellation class which also has extensive changes.
Not long after the F-110 final version appeared, and seemed to feature many of the same type of modifications, but now reconfigured as a light frigate. Navantia also claims it could build a large ship very quickly which would be "simular" to a Hobart class. They are also going to update the F-101-105 ships.
The F-110 while similar in size and hull form to the Hobart/F-105, is quite different in bridge stucture and fitout, only one gas turbine, 4 diesels etc. It has far less crew, 150 vs ~230..
Navantia's proposal is being assessed by RAND for viability, which seems to indicate it is broadly suitable for the RAN. There would be no need to assess it unless it was broadly suitable.
We don't know what exactly being assessed. If it is new build, improve F-105 as proposed for the Constellation class. Or New build F-105 for the Sea5000, or F-110 frigates, or F-110 hulls with 48 VLS and a destroyer type fitout, or some classic form of the Hobart class made to meet modern code and equipment as older equipment is not available anymore and not up to code. The F-110 has been designed to operate alongside the F-105 and Spain intends to keep both classes operating.
thanks very much for the clarification of the Navantia class F-100/105/110 development. As long as any “Batch 2” Hobart class build was to the upgraded F-110 standard that seems a viable candidate for a “tier 1” warship for the RAN.
I am not wishing to imply that I think the Navantia offer should win the decision. It will depend on many factors. But I do think the RAN needs more “tier 1” warships. Therefore while switching the Arafura build to a “tier 2” warship makes sense in terms of the DSR, we should not lose sight of the need to make up for lost time building up the “tier 1“ hull numbers.
Given your comments on crew numbers I can understand why the Constellation class is a less viable alternative.
