[Notes] This is T31 thread, I know. But, T13 program itself, and for the Rosyth yard to "survive", export is essential. So, export discussion must be deeply related to T31. But, wait. This is NEWS thread. So, I shall move to..... where? --> Sorry, help me admins.
On T26 thread, Brasil-san linked very nice movie of Tamandaré Class corvettes. https://youtu.be/aRmPiu_wS9s
Remarkably "similar" to T31, except for hull-size and standard, and even better in ASW and SSM.
In this movie, many good info is there.
1- CAMM number looks like 12 (1:33), using mushroom. (But LM says Brazil adopted ExLS. Not in this corvette?)
2- It carries 4 ISO containers (1:43)
3- 107.2 x 16 m, 3500t weight
4- Other weapons are, 1x 76mm gun (looks not with DARTS), 4x Exocet SSM, and a few guns.
5- It does NOT carry 40 mm gun (which was common to Brazilian warships to date. Not sure it is final, though).
6- No range/endurance info, as far as I know, but the failed Damen-10514 proposal states, "5000nm and 20 days". So, may be similar.
So, 12-SAM, 1-mid-cal-gun, 4-to-8-SSM and hull-sonar with helicopter, looks like common armament level as a typical heavy corvette / light-light frigate of the day. T31 is armed as a "typical heavy corvette of the day, but without ASW". Looks very similar to French Floreal-class. Only difference is better hull standard and lack of SSM.
(SAM difference is important, but it just reflects the difference of era = 1990s vs 2020s). Floreal hull is significantly enhanced merchant ship standard, which I understand is comparable to current OPV standard, like adopted in Mexican Damen 10514.
For Arrowhead 140 to get export, MEKO A100/A200, Damen 10514, Gowind2500 is clearly a good rival. "NATO frigate standard-hull" is good, but it is expensive and not popular in export market. So, Arrowhead 140 must be "one rank higher" assets = with less export chance (because higher ranked nations tend to have their own shipbuilding industry).
- New Zealand is very very important.
- Portugal: ENVC Shipyard is building their OPV = not much different from Babcock. Not easy, because they will think "if Babcock can build Arrowhead 140 by their own, ENVC Shipyard might be able to do it as well". Logical.
- Chili ASMAR ship yard is the same = not much different from Babcock. Not easy, again.
- Gulf states. May be, for example, Oman. But, other nations are already "booked" by French and Italian ships, look like.
I really really think T31 MUST aim at New Zealand as much as possible. Delaying the build program to enable RNZN to join in 2033-2035 (delivery) or finding a stop-gap (several MHC?) to "save the day" on Rosyth, between 2028 to 2033, will be of very high priority. I can see no other big chance, at least for now.
